You hired a great LCSW six weeks ago. She’s seeing patients. You can’t bill a dime for any of it because three commercial payers still haven’t loaded her — and one of them lost the application packet for the second time. Payroll keeps going out anyway.

This is the credentialing timeline problem in behavioral health, and it’s not getting faster. Here’s what to actually expect by payer type, and the levers that move the needle.

The short version

  • Commercial payers: 60–120 days on a clean file. Aetna and Cigna trend faster; UnitedHealthcare/Optum Behavioral runs longer because the medical and behavioral arms don’t always sync.
  • Medicaid MCOs: 90–180 days. State Medicaid enrollment must clear before MCO loading — the steps can’t run in parallel.
  • Medicare: 60–90 days through PECOS when nothing kicks back. Add 30–45 days for each data mismatch.
  • The biggest accelerator: a complete, error-free packet on day one. Most delays are self-inflicted at submission.

How long does behavioral health credentialing take by payer?

Commercial plans (Aetna, Cigna, UnitedHealthcare, Humana, regional BCBS)

Plan on 60–120 days from a clean submission to a loaded provider record. Aetna and Cigna are usually the quickest when the application is complete. UnitedHealthcare/Optum Behavioral runs longer because the behavioral arm and medical arm don’t always sync, and you’ll occasionally chase the file across two queues.

Regional BCBS plans are the wild card. Some states process in 60 days; others routinely take 150+. If you operate in multiple states, build the longer timeline into hiring decisions.

Medicaid and Medicaid MCOs

Two-step process, and you can’t skip ahead. The clinician (and often the facility) must enroll with state Medicaid first — typically 30–90 days depending on the state. Only after the state issues a Medicaid ID can the MCOs (Sunshine, Molina, CareSource, Humana Healthy Horizons, etc.) begin their own loading, which adds another 45–90 days.

Realistic total: 90–180 days. Florida and Texas have improved; others still run paper-heavy workflows that drag.

Medicare

PECOS submissions for behavioral health providers (now including LCSWs and LMFTs after the 2024 expansion) generally process in 60–90 days. The catch is that any inconsistency — an old practice address, a mismatched NPI taxonomy, a typo in a license number — kicks the application into a development request that adds 30–45 days each round.

TRICARE and VA

TRICARE through Humana Military or TriWest typically runs 90–120 days. VA Community Care Network credentialing through Optum or TriWest is similar but more paperwork-heavy and usually requires extra facility-level documentation.

Why does behavioral health credentialing take longer than other specialties?

Three reasons worth naming directly:

Facility-level credentialing is layered on top of provider-level credentialing. For PHP, IOP, and residential SUD programs, payers credential the facility (often with a separate site visit or accreditation review) AND each rendering clinician. Both clocks have to finish before clean claims go out.

Behavioral health networks are managed separately. Optum Behavioral, Carelon (formerly Beacon), Magellan, and Evernorth Behavioral are carve-outs with their own queues, contacts, and application portals. Even if you’re already in-network medically, the behavioral side starts from scratch.

Levels of care complicate contracting. Getting credentialed isn’t the same as having ASAM levels (2.1, 3.5, 3.7) loaded correctly on the contract. Plenty of facilities finish credentialing, start billing, and then learn the payer only loaded outpatient — claims for residential bounce until contracting fixes the levels.

How can you speed up the credentialing timeline?

1. Submit a complete packet — once

The single biggest accelerator is not getting kicked back. CAQH attestations within 120 days, current malpractice with correct limits, board certifications not expired, work history with no unexplained gaps over 30 days, all licenses verified primary-source. Every error adds two to four weeks.

2. Start before the hire date when you can

If a clinician is licensed and CAQH-ready, begin payer applications the day the offer is signed. Don’t wait for day one. Eight weeks of overlap turns into eight weeks of billable revenue.

3. Track follow-ups weekly, not monthly

Most payer reps won’t call you when something is missing — the application just sits. A weekly status check (with a contact name, not a portal ticket) catches missing-document requests before they become 30-day delays.

4. Negotiate effective dates retroactive to application receipt

Some commercial payers will backdate the effective date to the application receipt date if you ask during contract negotiation. Not all will, but the ones that do can recover a month or more of revenue.

5. Keep credentialing and contracting on the same desk

When credentialing and contracting are split between vendors, levels of care get missed, fee schedules don’t match what was negotiated, and nobody owns the gap. Behavioral health is too specific for a generalist RCM shop to figure out on your timeline. Running the full stack in-house — credentialing, contracting, VOB, UR, billing, appeals — means nothing falls between desks.

What should you do while waiting for credentialing to finish?

Two practical moves:

Bill under a credentialed supervising provider where allowed. Some commercial payers and state Medicaid programs permit incident-to or supervised billing for non-credentialed clinicians under specific rules. Confirm in writing — don’t assume.

Track pending claims by clinician and payer. Hold and date-stamp encounters so the moment the provider loads, you can release a clean batch. Facilities that don’t track this lose timely-filing on a meaningful chunk of pre-effective-date services.

What’s the bottom line on credentialing timelines?

Plan for 90 days commercial, 120+ days Medicaid MCOs, and 60–90 days Medicare on a clean file. Build hiring and pro forma assumptions around those numbers, not the optimistic ones. The biggest speed gains come from submitting clean the first time and following up weekly with a real human at the payer — not from any shortcut on the back end.

Frequently Asked Questions

How long does it take to credential a behavioral health provider?

For a clean submission, expect 60–120 days for commercial payers, 90–180 days for Medicaid and Medicaid MCOs, and 60–90 days for Medicare. Behavioral health carve-outs (Optum Behavioral, Carelon, Magellan) tend to run on the longer end of those ranges.

Can you bill for services rendered before credentialing is complete?

Sometimes. Some commercial payers will backdate effective dates to the application receipt date if negotiated. A few states allow supervised or incident-to billing under a credentialed provider. Both require written confirmation from the payer — don’t assume eligibility.

Why does Medicaid credentialing take so long for behavioral health facilities?

Medicaid is a two-step process. The clinician and often the facility must enroll with state Medicaid first (30–90 days), and only then can the Medicaid MCOs begin their own loading process (another 45–90 days). The steps cannot run in parallel.

What’s the most common reason credentialing applications get delayed?

Incomplete or inconsistent submissions. Expired CAQH attestations, mismatched NPI taxonomies, missing malpractice coverage details, unexplained work history gaps, and outdated license info are the top culprits. Each kickback typically adds two to four weeks.

Is facility credentialing different from provider credentialing?

Yes. For PHP, IOP, and residential SUD programs, the facility is credentialed separately from each rendering clinician — often with site visits and accreditation review (Joint Commission or CARF). Both clocks must finish before clean claims can be submitted, and contracting must load the correct ASAM levels of care.

You pull the AR aging report Monday morning and 14% of last month’s claims came back denied. Is that bad? Average? A crisis? Most behavioral health operators can’t answer that question, because the denial benchmarks floating around online were built for primary care and hospital systems — not detox, residential, PHP, or IOP.

Behavioral health denials behave differently. The payer mix is different, the medical necessity bar is higher, and one botched concurrent review can wipe out a week of revenue. Before you accept a bad number as normal — or panic over a healthy one — here’s what the benchmarks actually look like for a behavioral health facility, and where the dollars are usually leaking.

What’s a good denial rate for behavioral health billing?

  • First-pass clean claim rate should sit at 92–95%. Below 90% means something upstream is broken — usually VOB, authorization, or coding.
  • Total initial denial rate of 5–10% is workable. 10–15% is a warning. Above 15% is bleeding.
  • Hard denial rate (claims you’ll never collect on) should stay under 2–3% of billed charges. Higher than that points to medical necessity or authorization failures, not coding nits.
  • Appeal overturn rate on substantive denials should hit 50%+ if your UR and documentation are solid.

Why are behavioral health denial rates higher than general medical?

Three structural reasons. First, levels of care — detox, residential, PHP, IOP — are subject to concurrent review, meaning a payer can cut authorization mid-stay even after they approved admission. Every level-of-care downgrade is a potential denial. Second, medical necessity criteria (ASAM, LOCUS, MCG) get interpreted aggressively by commercial payers and Medicaid MCOs, especially for residential SUD. Third, the codes themselves — H0010, H0015, H2036, 90837 — get scrutinized for frequency, duration, and modifier accuracy in ways a 99213 office visit doesn’t.

Add out-of-network billing, single case agreements, and the documentation burden of proving ongoing necessity, and the 3% denial rate often cited as the general medical benchmark isn’t realistic. A behavioral health facility running at 7% with strong appeal recovery is doing well. One running at 18% with no appeal process is leaving six figures a quarter on the table.

Where do most behavioral health denials actually come from?

From years of working denials across SUD and mental health facilities, the pattern is consistent. The bulk of denied dollars trace back to four buckets:

1. Authorization and concurrent review failures

The biggest dollar-value bucket. A missed concurrent review window, an authorization that lapses one day before discharge, a level-of-care downgrade nobody appealed in time. This is where utilization review earns its keep — or doesn’t. If your UR team is reactive instead of building the medical necessity case before the payer asks, this category will dominate your denial log.

2. Eligibility and benefit issues

Plan terminated. Behavioral health carved out to a different payer. Out-of-network benefits assumed but not confirmed. Deductible not met and patient responsibility not collected. A thorough verification of benefits at admission — not a 30-second phone check — prevents most of this. These denials are often technically appealable but rarely worth the labor cost to chase.

3. Coding and documentation mismatches

Wrong revenue code paired with the right HCPCS. Missing modifier on a 90837 when 90834 was supported by time documentation. Group therapy billed as individual. Usually fixable on rebill, but they tank your first-pass rate and slow cash by 30–60 days.

4. Timely filing and follow-up gaps

The denials that hurt most because they’re 100% preventable. A claim sits in a worklist for 95 days, gets denied for timely filing, and there’s no recourse. That’s a staffing and workflow problem, not a payer problem.

How do you calculate denial rate correctly?

Most facilities calculate denial rate wrong, which is why their number doesn’t match reality. Two ways to do it:

By claim count: Denied claims ÷ total claims submitted in the period. Easy to pull, but misleading — a $400 office visit denial counts the same as a $40,000 residential stay denial.

By dollar value: Denied charges ÷ total billed charges in the period. This tells you what’s actually at stake. Track both, but make business decisions off the dollar number.

Also separate initial denials from final denials after appeal. A 12% initial denial rate with 60% overturn becomes a ~5% net denial rate — very different conversation than a 12% net rate.

What do you do when your denial rate is too high?

Don’t start with appeals. Start upstream. Pull 60 days of denied claims, sort by denial reason code, and look at the top three reasons. They almost always account for 70%+ of the volume. If your top reason is CO-197 (no authorization), the fix is in admissions and UR, not billing. If it’s CO-50 (medical necessity), the fix is in clinical documentation. If it’s CO-29 (timely filing), the fix is workflow.

That diagnostic is exactly what our free 6-month billing audit produces for prospective facilities — we quantify which buckets are costing what, and whether the leak is upstream of billing or inside it. Most operators are surprised to learn the denial number isn’t a billing problem at all; it’s an admissions or clinical documentation problem showing up on the billing report.

How fast should denied claims be worked?

Touch every denial within 7 days of receipt. File the appeal within 30. If a denial sits longer than 14 days untouched, the probability of recovery drops sharply — payers count on attrition, and a stale denial is a paid one. Your AR aging by denial-status bucket should be a metric you look at weekly, not monthly.

If your denial rate is above 10% and you don’t know which of the four buckets is driving it, that’s the first thing worth fixing. Request the free 6-month billing audit and we’ll show you the breakdown before you commit to anything.

Frequently Asked Questions

What is considered a good denial rate for behavioral health billing?

A total initial denial rate of 5–10% is healthy for SUD and mental health facilities, with a first-pass clean claim rate of 92–95%. Hard denials (uncollectable) should stay under 2–3% of billed charges. Rates above 15% indicate systemic problems in authorization, VOB, or documentation.

Why are behavioral health denial rates higher than general medical denial rates?

Behavioral health levels of care are subject to concurrent review, meaning payers can downgrade or cut authorization mid-stay. Medical necessity criteria (ASAM, LOCUS, MCG) are applied aggressively for SUD and residential care, and codes like H0010, H0015, and 90837 face more scrutiny than standard E/M codes.

Should I measure denial rate by claim count or dollar value?

Track both, but make decisions based on dollar value. A residential stay denial and an office visit denial count equally by claim count, which distorts the picture. Denied charges divided by total billed charges shows what’s actually at risk.

What’s the difference between initial denial rate and net denial rate?

Initial denial rate is the percentage of claims denied on first submission. Net denial rate accounts for appeals you win back. A facility with a 12% initial denial rate and 60% appeal overturn has a roughly 5% net denial rate — a much more accurate picture of actual revenue loss.

How quickly should denied claims be worked?

Touch every denial within 7 days of receipt and file appeals within 30 days. Recovery probability drops sharply once a denial sits longer than 14 days untouched, and many payer appeal windows close at 60–180 days depending on contract.

You signed the contract three years ago, accepted the rates because you needed in-network status, and haven’t looked at it since. Meanwhile, your residential per diem hasn’t moved while staffing costs are up double digits, the payer has quietly tightened concurrent review from 7 days to 5, and your IOP rate is below what a competitor across town gets for the same CPT codes. That’s not a contract — that’s a slow bleed.

Renegotiation isn’t an annual ritual for most behavioral health operators. It should be. Here’s when to push, what leverage you actually have, and how to structure the ask so the payer engages instead of stalling.

The short version

  • Most SUD and mental health contracts include a renegotiation clause — usually 60–90 days written notice before the anniversary date. If you’ve never invoked it, you’re probably underpaid.
  • The strongest leverage points are census data, level-of-care mix, outcomes, and proof you’re filling a network gap the payer can’t easily replace.
  • Triggers to renegotiate now: rates older than 24 months, a new accreditation, a measurable shift in patient acuity, or the payer changing UR behavior mid-contract.
  • Plan for 4–9 months from prep to signed amendment. Commercial payers move slowly; Medicaid MCOs move slower.

When should you renegotiate a behavioral health payer contract?

There’s no universal calendar, but there are five specific triggers that should put a contract back on the table:

  1. The contract is more than 24 months old without a rate adjustment. Wage inflation alone justifies the conversation. If your rates haven’t moved since 2022, the payer is paying you in dollars that buy less labor than they used to.
  2. You’ve added a level of care or accreditation. Joint Commission, CARF, a new PHP track, medical detox capability — anything that changes your clinical footprint changes your value to the network.
  3. UR behavior has shifted. If a payer that used to authorize 21 days of residential is now cutting at 14, your effective rate dropped even if the per diem on paper didn’t. That’s a renegotiation conversation, not just an appeals problem.
  4. Your case mix has changed. Higher acuity, more co-occurring, more medically complex admits — document it. You’re delivering more clinical value per admission than you were when the contract was signed.
  5. A competitor closed or left the network. Network adequacy is a real lever, especially in markets where the payer needs in-network beds for ASAM 3.5 or 3.7.

What leverage do you have with commercial payers and Medicaid MCOs?

Operators often assume they have none. That’s usually wrong. Leverage comes from data the payer doesn’t already have on you:

  • Length of stay vs. expected. If your average residential LOS runs below the payer’s book of business, you’re saving them money. Show it.
  • Readmission rates. 30- and 90-day readmissions are the metric medical directors care about. If yours are lower than regional norms, lead with that.
  • Completion rates and step-down conversion. A patient who completes residential and steps down to PHP/IOP is cheaper for the payer long-term than one who drops out and re-presents in detox six weeks later.
  • Network adequacy gaps. Pull the payer’s own provider directory in your zip codes. If there are three in-network residential providers and one of them stopped admitting, that’s a conversation starter.
  • Specialty populations. Adolescents, dual-diagnosis with serious mental illness, perinatal SUD, professionals’ programs — anything narrow and hard to replace strengthens your position.

Payers respond to specificity. “We deserve a rate increase” goes nowhere. “Our 90-day readmission rate is X, our average LOS is Y days below your book average, and we’re one of two in-network 3.5 providers in this county” gets a meeting.

How long does payer contract renegotiation actually take?

Plan for 4–9 months. The phases:

  • Weeks 1–4: Internal prep. Pull two years of claims data by payer, by CPT, by level of care. Calculate effective reimbursement (billed vs. paid vs. authorized days). Identify your top three asks.
  • Weeks 4–8: Outreach. Submit a written renegotiation request to the provider relations rep, citing the contract’s notice provision. Attach a one-page summary of your value proposition. Don’t lead with the rate ask.
  • Months 2–5: Back-and-forth. Expect a counter that’s lower than your ask, requests for more data, and a 30–60 day silence period. This is normal. Don’t escalate prematurely.
  • Months 5–9: Redlines and signature. Once a verbal agreement is reached, the amendment cycle through legal can take 60–90 days on its own.

Medicaid MCO contracts move on a different clock entirely — often tied to state contract years and rate floors set by the state Medicaid agency. Your room to move on rate is narrower, but language around UR, retro-authorizations, and timely filing is often negotiable.

Which contract terms matter as much as the rate?

Operators fixate on per diems and CPT rates. The fine print often costs more than the headline number:

  • Timely filing windows. 90 days vs. 180 days is the difference between a manageable AR and writing off legitimate claims.
  • Authorization requirements. Concurrent review intervals, retro-auth allowances, and what happens when a peer-to-peer is requested but not scheduled within the payer’s own SLA.
  • Appeal rights and timelines. Some contracts limit you to one level of internal appeal. Push for two, plus external review language.
  • Termination without cause. 90-day notice is standard. Anything shorter is a problem.
  • Rate escalators. An annual CPI-tied bump, even at 2–3%, is worth more over five years than a one-time increase.

This is where having a team that handles contracting and contract negotiations alongside billing matters. The billers see which contract terms actually cost money in practice — short timely filing windows, narrow auth definitions, ambiguous level-of-care language — and that intelligence feeds the next negotiation. At Global AHS we keep contracting, utilization review, and billing under one roof specifically because the data flows both directions: UR patterns inform what to renegotiate, and contract language informs how to bill cleaner.

What’s the biggest mistake operators make in payer negotiations?

Treating it as a single conversation instead of a process. Operators send one email, get a soft no, and walk away for another two years. Payers count on that. The facilities that get rate increases are the ones who treat the relationship as ongoing — quarterly check-ins with provider relations, sharing outcomes data unprompted, flagging issues before they become formal disputes. By the time the renegotiation window opens, the payer already knows who you are and what you deliver.

The second mistake: negotiating without clean data. If you can’t show your own numbers — LOS, readmissions, denial rates by reason code, average days in AR by payer — you’re negotiating on vibes. The payer is not.

Frequently Asked Questions

How often should behavioral health facilities renegotiate payer contracts?

Review every contract annually and formally renegotiate every 24–36 months at minimum. If rates haven’t moved in three years, you’re effectively taking a pay cut every year due to wage and operating cost inflation.

Can you renegotiate a payer contract mid-term?

Sometimes. Most contracts allow amendments at any point if both parties agree. Mid-term renegotiation usually requires a triggering event — a new level of care, a documented shift in payer behavior, or a network adequacy issue the payer needs to solve.

What data should I bring to a payer rate negotiation?

Two years of claims data by CPT and level of care, average length of stay vs. payer norms, 30- and 90-day readmission rates, completion and step-down rates, denial and appeal outcomes, and network adequacy analysis for your service area.

Do Medicaid MCOs negotiate rates with behavioral health providers?

Rate flexibility is limited because state Medicaid agencies often set floors, but MCO contracts have negotiable language around timely filing, authorization timelines, retro-authorizations, and appeal rights. Those terms often affect collections more than the headline rate.

Should I hire someone to handle payer contract negotiations?

If you don’t have an in-house contracting lead with behavioral health experience, yes. The ROI on a single rate increase or improved timely filing window typically pays for outside contracting support several times over, and a specialist will know which terms in your current contract are actually costing you.

A patient is sitting in admissions. Their commercial plan won’t cover your facility in-network, the clinical need is clear, the family wants treatment to start tomorrow, and the payer’s case manager just floated a single case agreement at a per diem that won’t cover your nursing line. Take it, walk away, or push back?

Single case agreements (SCAs) are one of the most leverageable — and most under-negotiated — pieces of out-of-network behavioral health billing. Most facilities accept the first number a payer floats. They shouldn’t.

The short version

  • Pursue an SCA when there’s a real network adequacy gap, a continuity-of-care argument, or a specialized clinical capability the in-network panel doesn’t offer.
  • The payer’s first offer is almost never their ceiling. Expect 15–40% movement on rate when you have leverage and documentation.
  • Rate is one variable. Authorization length, level-of-care step-downs, covered codes, and timely-filing windows are all negotiable in the same conversation.
  • Get every term in writing — rate, CPT and revenue codes, auth period, appeal rights — before the patient is admitted.

When is a single case agreement worth pursuing?

Not every out-of-network admission warrants an SCA. The cases that do share a few traits:

Network adequacy gaps

If the payer’s in-network options for residential SUD treatment are full, geographically unreasonable, or clinically inappropriate (no co-occurring capability, no MAT, no trauma-informed program), you have an adequacy argument. State parity laws and federal MHPAEA rules give it teeth. Document the gap before you call: which in-network facilities you contacted, wait times, distance from the patient’s home, clinical fit.

Continuity of care

The patient stepped down from a higher level of care at your facility, or has an established therapeutic relationship with a clinician on staff. Payers are obligated to consider continuity. This is one of the strongest arguments for an SCA at parity with in-network rates.

Specialized clinical capability

Your program offers something the in-network panel doesn’t — pregnant women’s residential, adolescent SUD, dual-diagnosis with active psychosis, complex withdrawal protocols. Name it specifically in the request.

If none of those apply and the patient simply prefers your facility, an SCA is unlikely and probably not worth chasing. Put that energy into a verified out-of-network benefits quote and a transparent patient financial conversation.

How do you negotiate a higher SCA rate?

Rate negotiation is the part most facilities skip. Here’s what actually moves the number:

Anchor with your billed charge

Don’t open with what you’ll accept. Open with your billed charge or your standard out-of-network rate. The payer will counter low — that’s fine. You’ve established the ceiling.

Reference comparable in-network rates

If you carry in-network contracts with other commercial payers, you know the going rate for residential, PHP, and IOP in your market. Cite a range. “Residential SUD is contracting between $X and $Y in this region” is a defensible anchor without disclosing a specific contract.

Bundle the asks

If the payer won’t move on per diem, push on length of stay. A modest rate at 21 days authorized upfront beats a higher rate with 7 days and a UR fight every week. Same conversation, different lever.

Frame the SCA as cost-avoidance

If the patient otherwise lands in an ED, an inpatient psych unit, or relapses into a medical detox admission within 60 days, that costs the payer more than your SCA. Make that math explicit.

Know when to decline

An SCA at 35% of billed charges with a 7-day cap and no appeal rights is not a deal — it’s a liability. Walking away is sometimes the right answer, especially if your census allows it. Payers track facilities that accept anything, and they price accordingly next time.

What terms matter besides the per diem?

The rate gets all the attention. These often matter more:

  • Authorization length. Negotiate the initial auth period — 14 or 21 days for residential is reasonable. Shorter auths mean more concurrent reviews and more denial risk.
  • Level-of-care continuum. Build step-down language into the SCA: residential to PHP to IOP under the same agreement. Otherwise you renegotiate at every transition.
  • Covered codes. Specify CPT and revenue codes — H0010, H0011, H0015, H0035, plus room and board revenue codes. If a code isn’t named, expect it to be denied.
  • Timely filing. Out-of-network SCAs sometimes carry 90-day filing windows. Push for 180 or 365.
  • Appeal rights. Confirm in writing that standard internal and external appeal rights apply to denied claims under the SCA. Some payers try to waive these in exchange for the agreement.

Who should be negotiating SCAs at your facility?

This is where most treatment centers lose money. The admissions coordinator who’s also running intake, insurance verification, and bed assignments is not the right person to negotiate a five-figure agreement under time pressure. Neither is the clinical director.

SCA negotiation sits at the intersection of billing, utilization review, and contracting. The person on the call needs to know your cost per day, your typical length of stay by level of care, what other payers in your market reimburse, and what authorization patterns the specific payer follows. That’s a billing-and-UR skill set, not an admissions one.

Behavioral health is a narrow specialty. Generalist RCM shops handle SCAs the same way they handle everything else — quickly, with a script. Global AHS works exclusively with addiction treatment and mental health facilities, which means the person picking up the phone has negotiated SCAs with the same case managers your payers will assign, on the same level-of-care codes, in the same week. That pattern recognition is what moves rates.

How do you protect the SCA after it’s signed?

Getting the agreement is half the work. Holding it together through the stay is the other half.

  • Send the signed SCA to your billing team and your UR team the same day. Both need it.
  • Bill exactly to the codes and rates specified. SCAs pay outside your normal fee schedule — claims need to be flagged so they don’t autoadjudicate at the wrong rate.
  • Track the auth end date. Concurrent review for SCA patients is the same as any other commercial case — miss it and the agreement doesn’t save you.
  • If a claim is denied or underpaid against the SCA terms, appeal with the agreement attached. These appeals win more often than standard ones because the contract is explicit.

Frequently Asked Questions

What is a single case agreement in addiction treatment?

A single case agreement (SCA) is a one-time contract between an out-of-network treatment facility and a health plan that establishes payment terms for a specific patient’s care. It’s used when an in-network option isn’t available or clinically appropriate, and it typically covers a defined level of care, length of stay, and reimbursement rate.

How long does it take to negotiate an SCA?

Most SCAs are negotiated within 24 to 72 hours when the clinical need is documented and the request is routed correctly. Complex cases — high-cost residential stays, multi-level-of-care agreements, or payers with multiple internal approvals — can take a week or longer. Starting the conversation before admission is critical.

What rate should I expect on a single case agreement?

Rates vary widely by market, payer, and level of care. As a general observation, SCAs for residential SUD treatment tend to land somewhere between Medicaid rates and billed charges, with significant room to negotiate based on network adequacy arguments and clinical specialization. The first offer is rarely the best one.

Can I negotiate an SCA after the patient is already admitted?

Yes, but you lose leverage. Once the patient is in your facility and stable, the payer knows you’re motivated to get paid for care already delivered. Whenever possible, negotiate and sign before admission, or at minimum within the first 24 hours.

Do single case agreements include appeal rights if a claim is denied?

They should, but not all SCAs do by default. Confirm in writing that standard internal and external appeal rights apply to claims billed under the agreement. If a payer pushes back on this, that’s a signal the rest of the terms deserve closer scrutiny.

A competitor across town went in-network with three commercial payers and doubled their census in six months. Meanwhile, your out-of-network admissions are slower, single-case agreements are dragging, and patient AR is creeping past 90 days. The instinct is to sign every contract you can get a meeting with. That’s usually a mistake.

In-network versus out-of-network isn’t a philosophy — it’s a math problem with a payer-by-payer answer. Here’s how to think about it before you sign anything.

The short version

  • In-network rates typically run 40–60% lower than OON reimbursement, but pay faster and shift patient balance risk off your books.
  • OON pays more per claim but increasingly requires single-case agreements, tougher medical necessity reviews, and tolerates higher denial rates.
  • The right mix depends on your level of care, geography, and which payers dominate your referral channels — not on what worked for the facility down the street.
  • The contracts you sign in year one set your revenue ceiling for the next three to five years.

How does in-network behavioral health billing actually pay?

Going in-network means signing a contract at a negotiated rate, agreeing to the payer’s utilization management rules, and accepting the contractual write-off on every claim. The upside is real: clean claims usually turn around in 14–30 days, patient cost-shares are predictable, and you land in the payer’s member directory — which drives organic admissions.

The downside is the rate sheet. Commercial payers will often open with a rate barely above Medicaid for residential SUD or PHP. Sign that rate without negotiating — or without knowing the regional benchmarks for your level of care — and you’re locked in for the contract term. Renegotiation is possible but slow; most payers won’t revisit rates inside 18 months without a documented case.

The difference between an opening offer and a negotiated rate is frequently 15–25% on the same CPT codes. That’s where contracting and contract negotiations earn their keep.

What are the revenue tradeoffs of staying out-of-network?

OON trades reimbursement size for reimbursement certainty. A residential day at OON rates can pay two to three times the in-network rate, but you work harder for every dollar:

  • Patient responsibility sits with you. OON deductibles of $5,000–$10,000 are common, and collecting after discharge is its own operational burden.
  • Denial rates run higher. OON claims face more aggressive medical necessity reviews and more frequent downcoding than in-network claims for the same level of care.
  • Payer pressure is increasing. Several large commercial carriers have tightened OON behavioral health policies in the last 24 months, and that trend isn’t reversing.

OON can still be the right model — for facilities with strong outcomes data, premium accommodations, or specialized populations. It requires a UR team that defends medical necessity at every level of care change and an appeals process that doesn’t let timely-filing deadlines slip.

Which payers should you actually contract with?

Not every in-network contract is worth signing. Before you accept an offer, you need three things:

  1. Member density in your catchment area. A payer with 8% market share in your county is a different decision than one with 35%.
  2. The payer’s behavioral health utilization patterns. Some commercial payers approve PHP-to-IOP step-downs reliably; others fight every level of care change. That affects your effective reimbursement, not just the rate sheet.
  3. Their credentialing timeline. A payer that takes 120+ days to credential providers is worth less than one that credentials in 60.

Operators who go in-network without looking at referral source data tend to sign the wrong contracts first — usually whichever payer was easiest to get a meeting with. The contracts that grow your business are the ones whose members are already calling your admissions line.

Can you run a hybrid in-network and out-of-network model?

Yes, and most successful behavioral health operations do. The pattern usually looks like this: in-network with two or three regional commercial payers (and Medicaid MCOs, if you accept them) for stable baseline volume, OON with national commercial payers where rates are strong and SCAs are achievable, and an admissions screening process that routes each prospective patient to the right billing pathway.

The catch is operational. Hybrid models require tight coordination between admissions, verification of benefits, and UR. A patient routed incorrectly — admitted as OON when the plan would have paid in-network, or vice versa — costs real money and surfaces as a collection problem weeks later.

This is where behavioral-health-specific RCM matters. A generalist billing company learning your payer mix on your dime will miss these routing calls. Global AHS works in behavioral health and SUD billing only — the team reading the VOB has seen that exact plan, that exact payer, and that exact level of care a hundred times before.

How do you know if your current contracts are profitable?

Most operators can tell you their gross revenue per admission. Far fewer can tell you their net collection rate by payer, average days in AR by contract, or denial rate broken out by in-network versus OON. Without those numbers, you’re making contract decisions on instinct.

A six-month look-back at your billing data usually surfaces two or three contracts that aren’t pulling their weight — either the rate is too low, the denial rate is too high, or the payer is downgrading levels of care faster than your UR team can defend them. Those are the contracts to renegotiate or exit before you sign anything new.

The next step

If you don’t have those numbers in front of you, get them before you sign your next contract. Global AHS runs a free 6-month billing audit for treatment center operators — net collection by payer, AR aging by contract, denial patterns by level of care. Request the audit here, and you’ll know which contracts to keep, renegotiate, or walk away from.

Frequently Asked Questions

Is in-network or out-of-network better for a new behavioral health treatment center?

For most new facilities, a hybrid works best: one or two strategic in-network contracts to establish baseline volume and credibility, with OON billing for payers where rates and single-case agreements support stronger reimbursement. Going fully OON from day one creates cash flow risk; going fully in-network at opening rates caps your revenue ceiling early.

How much lower are in-network rates compared to out-of-network reimbursement?

It varies by payer, region, and level of care, but in-network rates for residential SUD, PHP, and IOP are commonly 40–60% lower than OON reimbursement on the same CPT codes. The tradeoff is faster payment, lower denial rates, and no patient balance collection risk.

Do single-case agreements pay as well as out-of-network claims used to?

Generally yes, when negotiated well. SCAs lock in a rate before admission and reduce the medical necessity fight at the back end. The challenge is that payers have become more selective about granting them, and the negotiation has to happen during admissions — not after the patient is already in care.

How long does it take to go in-network with a commercial behavioral health payer?

Credentialing and contracting together typically run 90–180 days from application to effective date. Some Medicaid MCOs move faster; some commercial payers take longer, especially when network adequacy in your area is already met.

Can you renegotiate an in-network rate that’s too low?

Yes, but rarely inside the first 18 months and never without documented justification — outcomes data, level-of-care mix, regional rate benchmarks, or a credible threat to terminate. Most operators leave money on the table because they don’t bring data to the renegotiation.

Your clinical director just got off a seven-minute peer-to-peer for a residential client. The reviewing MD didn’t read the chart, asked two questions, and downgraded the authorization to PHP anyway. That’s a week of revenue gone, and the written appeal is due in five business days.

This is the grind behind utilization review denial appeals — and most of it is winnable if your process is built for it.

TL;DR: What makes UR appeals win

  • Speak the criteria, not the narrative. Reviewers score against ASAM or MCG — your argument has to map to those dimensions directly.
  • Prep the peer-to-peer like a deposition. One page, six bullet points, the exact clinical markers that failed the lower level of care.
  • Written appeals win on specifics. Vitals, quotes, UDS results, failed outpatient history — not adjectives.
  • Track every denial reason by payer. Patterns repeat, and the second appeal is easier when you’ve seen the first.

Why do peer-to-peer reviews feel rigged before the call starts?

Because they kind of are. The payer’s medical director has a queue of 15 cases, a rubric in front of them, and about six minutes per call. They’re not reading your progress notes live. They’re listening for specific words that map to medical necessity criteria — and if your clinician walks in telling a story instead of hitting those words, the call is over before it starts.

The fix isn’t a better storyteller. It’s a pre-call sheet. Before every peer-to-peer, the UR team should hand the clinician a half-page document with:

  • The exact denial reason quoted from the payer letter
  • The ASAM dimension(s) that justify the level of care being requested (Dimension 3 for emotional/behavioral, Dimension 5 for relapse risk, etc.)
  • Three to five concrete clinical markers from the last 48 hours — CIWA scores, PHQ-9, SI documentation, failed step-downs, positive UDS, medication non-compliance
  • The failed-at-lower-level-of-care history, if it exists
  • A one-sentence summary of why discharge or downgrade is unsafe right now

Clinicians who walk into the call with that sheet convert peer-to-peers at meaningfully higher rates than those winging it from memory. That’s an industry observation, not a controlled study — but anyone running a busy UR desk will tell you the same thing.

What should a written UR appeal actually include?

Written appeals lose when they read like a treatment summary. They win when they read like a legal brief. Structure matters more than length.

1. Quote the denial reason verbatim

Open by citing the payer’s exact language and the date of the determination. This forces the reviewer on the other end to engage with the specific reason, not a general reassessment.

2. Cite the criteria set being applied

If the payer uses ASAM, reference the dimension. If they use MCG or InterQual, cite the specific guideline number. This signals that your appeal is scored against the same rubric they’re using.

3. Deliver the clinical evidence in bullets, not paragraphs

Reviewers skim. A wall of prose gets a wall of prose in return — denial upheld. Bullets with dates, scores, and direct chart quotes force the reviewer to either rebut each point or concede.

4. Address the downgrade alternative directly

If the denial offers a lower level of care, explain specifically why that setting cannot safely manage this patient right now. “Outpatient is insufficient because…” — then three reasons tied to documented behavior.

5. Attach the right pages, not the whole chart

Cherry-pick the two or three progress notes, the admission H&P, and any relevant labs. A 40-page attachment gets less attention than a 6-page one.

How do you prevent UR denials before they happen?

The best appeal is the one you don’t have to file. Three upstream fixes catch most problems before a denial letter goes out:

  • Concurrent review timing. Submit the next authorization request 48–72 hours before the current auth expires, not the day of. Late submissions get pended, and pended cases get denied.
  • Documentation templates tied to criteria. If your progress note template prompts clinicians to document across all six ASAM dimensions daily, your UR nurse has the ammunition they need without hunting.
  • Denial pattern tracking by payer. When you can see that one commercial payer consistently denies residential on Dimension 5 after day 14, you adjust documentation on day 10 — not after the denial.

This is where an in-house utilization review function that also owns billing matters. When the same team sees the denial, writes the appeal, and watches the cash hit (or not), the feedback loop is tight. When UR is one vendor and billing is another, the lessons don’t cross the gap. Global AHS runs the full RCM stack under one roof — UR, billing, VOB, appeals, credentialing — so a denial trend on Tuesday becomes a documentation change on Wednesday.

When should you escalate to an external review?

After two internal appeals fail, most commercial plans allow an Independent Review Organization (IRO) review. Escalate when:

  • The dollar amount justifies the clinical time — typically several thousand dollars or more per episode
  • You have strong documentation and the denial rationale is weak or internally inconsistent
  • The payer has a pattern of overturning at IRO for this diagnosis or level of care

IROs overturn a meaningful share of behavioral health denials because the reviewing physicians are usually contracted specialists, not the payer’s in-house staff. Don’t leave this option on the table for high-dollar cases.

Which UR denial reasons are hardest to overturn?

Three show up consistently and each requires a different strategy:

  • “Lack of medical necessity for continued stay.” Win with day-over-day functional decline data or new clinical events — not “patient is still working on their issues.”
  • “Member could be treated at a lower level of care.” Win with documented failed step-down attempts, environmental instability, or acute safety concerns.
  • “Services not covered under the plan.” This is a benefits issue, not a clinical one. The appeal goes to the benefits administrator with plan language, not to a medical reviewer.

Knowing which category a denial falls into decides who writes the appeal and what evidence goes in it. A clinical appeal on a benefits denial is a wasted appeal.

Next step

If your overturn rate is under 40% or your peer-to-peers feel like coin flips, the fix is usually upstream of the appeal itself. Global AHS offers a free 6-month billing and UR audit that quantifies where denials are coming from and what’s winnable. Request the audit here.

Frequently Asked Questions

How long do I have to file a UR denial appeal?

Timelines vary by payer and plan type, but most commercial plans allow 60–180 days for an internal appeal and require expedited appeals (for active admissions) to be filed within 24–72 hours of the denial. Medicaid MCOs and Medicare Advantage have their own timelines. Read the denial letter — the deadline is always stated there, and missing it forfeits the appeal.

Should the attending physician or the UR nurse do the peer-to-peer?

The attending or a physician familiar with the case should do it whenever possible. Payer medical directors give more weight to peer physicians, and clinical nuances land better MD-to-MD. UR nurses should prep the call, not run it, unless plan rules require otherwise.

Can I appeal a denial after the patient has already discharged?

Yes. Post-service appeals are standard and have their own timelines (often 180 days or longer for commercial plans). The clinical argument is the same — the documentation just has to support medical necessity as of the dates of service in question.

What’s the difference between a reconsideration and a formal appeal?

A reconsideration is typically an informal re-review by the same payer, sometimes without a new peer-to-peer, and doesn’t always count against your formal appeal levels. A formal appeal triggers the plan’s defined appeal process. Know which one you’re filing — it affects your remaining options if it fails.

What’s a normal UR denial rate for a behavioral health facility?

It varies heavily by payer mix, level of care, and documentation quality. As an industry observation, facilities with strong concurrent review processes run lower denial rates than those submitting authorizations reactively. The bigger question isn’t the raw denial rate — it’s your overturn rate on appeal. Overturn rates below 40% usually indicate a documentation or process problem, not bad luck.

Your 90837 hits the clearinghouse at $250. Two weeks later the EOB lands at $68 — a MultiPlan or Viant “repriced” amount the payer treats as payment in full. No contract, no signature, no agreement from you. Just a take-it-or-leave-it number and a member you can’t balance bill without blowing up the admissions relationship.

This is the out-of-network repricing squeeze, and if you run a behavioral health or SUD facility, it’s quietly eroding 20–40% of your expected OON revenue. The good news: repriced offers are offers, not adjudications. You can push back. The question is when it’s worth the effort.

TL;DR

  • Repriced offers from third-party networks (MultiPlan/Viant/Zelis/Data iSight) are negotiable — signing the single-case agreement is optional.
  • Accept quickly when the offer is at or above your usual contracted rate, cash flow is tight, or the member has high deductible exposure you’d rather not collect on.
  • Challenge when the offer falls below your cost-of-care floor, the methodology is unclear, or the payer has a documented history of paying higher on similar CPT/level-of-care combinations.
  • Document your cost basis, UCR benchmarks, and prior payment history before the call — repricers negotiate on data, not outrage.

Why does claim repricing hit behavioral health harder than other specialties?

When a patient has OON benefits, the payer often routes the claim to a third-party repricing network — MultiPlan, Viant, Zelis, Data iSight, and similar — that offers the provider a “negotiated” rate lower than billed charges but higher than the payer’s default OON allowable. The repricer takes a percentage of the savings. The payer treats the repriced amount as payment in full and zeroes out member balance-billing exposure.

Behavioral health gets hit harder than most specialties for three reasons. First, OON utilization is high — networks are thin, especially for residential and PHP. Second, billed charges for RTC, PHP, and IOP vary wildly facility to facility, which gives repricers a wide range to anchor low. Third, parity enforcement on OON reimbursement methodology is inconsistent, so repricers can lean on outdated UCR data without much pushback.

The result: a $1,200/day PHP claim gets repriced to $380. A $90791 intake at $450 gets offered $185. If you sign, that’s the ceiling.

When should you just accept the repriced offer?

Not every claim is worth a negotiation call. Accept the offer when:

  • The offer meets or beats your in-network equivalent. If your BCBS contracted rate for H0015 is $320/day and the repricer offers $340, take it and move on.
  • The member has a $7,500 OON deductible you’d otherwise chase. A signed single-case agreement often means the payer pays at in-network benefits — your net is higher than billing the patient for a deductible you’ll collect 30 cents on the dollar on.
  • The claim is older than 90 days and AR is aging. Cash today beats a slightly better number in 60 days, especially if the alternative is an appeal cycle.
  • The CPT code is low-dollar and high-volume. Individual therapy sessions aren’t worth a 45-minute negotiation call each. Batch them or accept the standard offer.

When is it worth challenging the repricer?

Push back when at least one of these is true:

  • The offer is below your documented cost of care. If your all-in per diem cost for residential is $540 and the offer is $410, signing locks in a loss.
  • The payer has paid higher on identical claims in the last 12 months. Repricers anchor low by default. If you have EOBs showing the same payer paid $620/day last quarter, you have leverage.
  • The methodology is opaque. If the offer letter cites “usual and customary” with no percentile or data source, ask. FAIR Health benchmarks at the 80th percentile typically run 2–3x Medicare for behavioral health services — far above most repriced offers.
  • It’s a high-dollar authorization-heavy episode. A 30-day RTC stay with solid UR documentation is worth fighting for. The repricer knows it too.

How do you negotiate a higher reimbursement with MultiPlan or Viant?

Repricers run phone-based negotiation desks. The reps have authority bands — they can typically move 10–25% from the initial offer without escalation, more with a supervisor. Here’s the approach that works:

1. Come with three numbers, not one

Have your billed charge, your walk-away floor (cost plus margin), and your target. Anchor at billed charges, land at target, never go below floor. If they won’t move above your floor, hang up and appeal the underpayment through the payer directly.

2. Cite comparable paid claims

“On claim [ID] for the same CPT and diagnosis family, this payer paid $X on [date].” This is the single most effective lever. Repricers have access to their own historical data — they know when you’re right.

3. Reference benchmarks, not emotion

FAIR Health percentiles, Medicare multiples, and state parity guidance carry weight. “This is below 150% of Medicare for H0015” lands harder than “this is unfair.”

4. Get the SCA language right before signing

Make sure the single-case agreement covers the full date range, all CPT codes on the claim, and specifies the payer will process at in-network benefits with no member balance beyond standard cost-share. Missing language here is where “accepted” offers still result in underpayments.

What do you do when the repricer won’t budge?

If the repricer won’t move above your floor, decline the offer in writing and let the claim adjudicate at the payer’s default OON allowable. Then:

  • Appeal the underpayment citing plan documents, parity (if commercial), and UCR benchmarks.
  • If the member has OON benefits, bill the patient responsibility per the EOB — but coordinate with admissions so it doesn’t become a surprise.
  • Track the payer and repricer pattern. Repeated lowballing on a specific payer is grounds for a contracting conversation. Sometimes the answer is to go in-network at a rate you’d actually accept — our contracting team runs these analyses regularly.

The operators who win at repricing aren’t the ones who fight every claim — they’re the ones with clean data on what each payer has paid historically, a defensible cost floor, and a workflow that flags underpayments within days, not months. Repricing patterns by payer look very different in SUD and mental health than they do in orthopedics, which is why we built behavioral health billing as a specialty practice rather than a generalist service.

Frequently Asked Questions

Is a repriced offer from MultiPlan or Viant legally binding if I don’t sign?

No. Repriced offers are proposals for a single-case agreement. Without your signature, the payer must adjudicate the claim at the plan’s default OON allowable per the member’s benefits. You retain the right to appeal and, depending on state law and the member’s plan, to balance bill.

How much can I typically negotiate above the initial repriced offer?

Industry observation: first-line negotiators usually have authority to move 10–25% from the opening offer. Supervisor escalations can yield more, especially on high-dollar residential or PHP claims with strong clinical documentation and comparable paid-claim data to cite.

Does accepting a repriced offer waive my right to appeal?

Usually yes, for that specific claim. A signed single-case agreement typically includes language accepting the amount as payment in full. Read the SCA carefully — some include broader waivers that affect future claims or member balance billing rights.

Should I pursue the patient for the balance if I decline the repriced offer?

Only if the member has OON benefits and your admissions process disclosed OON financial responsibility clearly. Balance billing without upfront disclosure damages referral relationships and, under the No Surprises Act, can expose you to penalties depending on the service setting and notice requirements.

How quickly do I need to respond to a repricing offer?

Most offers include a 5–10 business day response window. Missing the window usually means the claim adjudicates at the default OON rate, which is often lower than the repriced offer. Build a workflow that flags repricing letters within 48 hours of receipt.

Are there CPT codes where repricing offers are consistently worse than default OON allowables?

Yes. H0015 (IOP), H0035 (PHP), and H2036 (RTC) per diems vary widely by repricer and payer. Compare the offer to the payer’s published OON methodology before signing — occasionally the default allowable at a FAIR Health percentile is higher than what the repricer proposed.

You pull the aging report Monday morning and a third of your AR is over 90 days. Your billing company blames “payer delays.” But admissions is sending clean intakes, census is steady, and the same claims keep showing up in the 120+ bucket month after month. The payers aren’t the problem. Your vendor is.

When cash flow slides at a behavioral health facility, operators blame payers first. Sometimes that’s right. More often, the billing vendor is missing the basics — and the symptoms are specific enough that an operator can diagnose the problem in an afternoon.

TL;DR: How to spot a failing billing vendor

  • AR over 90 days climbing past 20–25% is almost never a payer problem — it’s a follow-up problem.
  • First-pass denial rates above 10% on core SUD and mental health codes point to front-end gaps in VOB, auth, or coding.
  • Vague reporting — “we’re working on it” without claim-level detail — means no one is tracking the work.
  • Slow or templated communication from your billing contact is the leading indicator of everything else on this list.

What should behavioral health AR aging actually look like?

A healthy behavioral health AR distribution skews heavily into the 0–30 day bucket. As an industry observation, well-run SUD and mental health billing operations keep AR over 90 days in the 15–20% range, with total days in AR under 45. Commercial payers for residential and PHP/IOP services pay slower than primary care — but not unboundedly slower.

Warning signs in your aging report:

  • The over-90 bucket is growing month over month, not shrinking.
  • Large dollar amounts sitting in 120+ with no appeal activity logged.
  • Claims in “submitted” status for 30+ days with no payer acknowledgment — usually meaning they were never actually submitted, or were rejected at the clearinghouse and ignored.
  • The same claims appear in the aging report three months in a row with no status change.

Pull a claim-level aging report — not a summary. If your vendor can’t produce one within 24 hours, that itself is a red flag.

What denial rate is acceptable for SUD and mental health billing?

First-pass denial rates in behavioral health run higher than other specialties because of utilization review, level-of-care disputes, and auth complexity. Even so, a first-pass denial rate above 10% on core services — 90837, 90834, H0015, H0018, H2036 — usually means preventable errors are slipping through. Above 15%, you have a systemic problem.

Look at the denial reason codes. The ones that point directly to vendor underperformance:

  • CO-197 (auth missing/invalid) — a VOB and UR handoff failure.
  • CO-16 (claim/service lacks information) — sloppy claim scrubbing.
  • CO-45 or CO-97 recurring on the same CPT codes — nobody is correcting the fee schedule or bundling logic.
  • Timely filing denials — these should almost never happen. If you’re seeing them, claims are sitting in someone’s queue.

Denials are recoverable if they’re worked fast. The problem isn’t that denials happen — it’s that they’re not appealed inside the payer’s window. Ask your vendor for their appeal overturn rate. If they don’t track it, they’re not working appeals with any rigor.

Why is my billing company so hard to reach?

Communication is the leading indicator. Every operator who switches to Global AHS after a bad vendor relationship tells the same story: it started with slower email replies, then a ticketing portal replaced the phone, then the assigned contact turned over and the new person didn’t know the facility.

Specific red flags:

  • Your dedicated contact has changed twice in six months.
  • Questions about specific claims take 48+ hours to answer.
  • Reports come monthly instead of weekly, and they’re PDFs instead of exports you can filter.
  • You’re routed through a support queue instead of a person who knows your facility’s payer mix.

Behavioral health billing isn’t a ticketing problem. It’s a relationships-with-payers problem, and those relationships don’t form when the person on your account rotates every quarter.

What reporting should a billing vendor actually provide?

If your monthly report is a one-page summary of charges, payments, and adjustments, you’re flying blind. At minimum, you should have ongoing access to:

  • Claim-level AR aging by payer.
  • Denial log with reason code, date received, action taken, and current status.
  • First-pass clean claim rate and first-pass denial rate, broken out by payer.
  • Days in AR trended over the last 6–12 months.
  • UR approvals vs. denials by level of care.
  • Appeal pipeline — what’s pending, what’s overturned, what’s lost.

A vendor that can’t show you these numbers on demand doesn’t have them. And if they don’t have them, they’re not managing to them.

How do front-end gaps show up in back-end performance?

A lot of what looks like billing underperformance is actually broken handoffs upstream. Weak verification of benefits leads to surprise out-of-network claims. Missed auth extensions from utilization review lead to mid-stay denials that no appeal will save. Lapsed credentialing leads to “provider not par” denials that sit in AR for months.

This is why fragmented vendor stacks — one company doing VOB, another doing UR, another doing billing — tend to underperform. Nothing gets caught early because no one owns the full chain. Consolidating the stack, or at least auditing the handoffs, fixes more denial problems than hiring a better coder ever will. Worth looking at alongside your billing workflow.

How do I verify my billing company is underperforming this week?

Three things to do before Friday:

  1. Pull a claim-level aging report. Sort by age bucket and dollar amount. Identify the top 20 oldest claims and ask your vendor, claim by claim, what’s being done on each.
  2. Run a denial audit on the last 90 days. Group by reason code. Anything that clusters around auth, eligibility, or coding is preventable.
  3. Request an appeal log. Count how many denials from the last quarter were actually appealed. The gap between denied and appealed is usually where your cash is.

If those three exercises surface gaps — or if your vendor pushes back on producing the data — you have your answer. Global AHS runs a free 6-month billing audit for treatment centers that want the numbers quantified before making any decisions. Request the audit here.

Frequently Asked Questions

What percentage of AR over 90 days is considered a red flag?

As an industry observation, behavioral health facilities with well-run billing operations keep AR over 90 days in the 15–20% range. Consistently above 25%, or climbing month over month, usually points to follow-up and appeal work not being done — not to slow payers.

What is a reasonable first-pass denial rate for SUD and mental health claims?

Behavioral health runs higher than primary care due to UR and level-of-care complexity, but a first-pass denial rate above 10% on core CPT and HCPCS codes (90837, H0015, H0018, H2036, etc.) generally indicates preventable front-end errors. Above 15% is systemic.

How quickly should my billing company respond to claim-specific questions?

Same business day for urgent questions, within 24 hours for routine claim status inquiries. If you’re waiting 48+ hours or getting templated replies from a ticketing portal, that’s a leading indicator of deeper performance issues.

What reports should I be getting from my billing vendor?

At minimum: claim-level AR aging by payer, a denial log with reason codes and current status, first-pass clean claim rate, days in AR trended over time, UR outcomes by level of care, and an active appeal pipeline. You should be able to pull these on demand, not wait for a monthly PDF.

Can switching billing companies mid-year cause cash flow disruption?

There’s always a transition period, but a structured handoff — running parallel for 30–60 days, transferring aging claims with documented status, and re-credentialing cleanly — typically stabilizes collections within one billing cycle. The bigger risk is staying with an underperforming vendor and watching AR age out past timely filing windows.

Your aging report is climbing past 90 days. Claims you submitted in March still haven’t been touched. Your current biller stopped returning calls two weeks ago, and the last UR got approved because your clinical director worked it on a Saturday when no one at the billing company picked up. You’ve already decided you need to switch. The question is how to do it without torching six figures in open AR.

Switching behavioral health billing companies is one of the higher-risk operational moves a treatment center can make. Get it wrong and claims get lost in transit, timely filing windows close, and cash drops for a quarter. Get it right and you recover revenue you didn’t know was stuck.

Here’s the checklist operators use to make the move, plus the questions that separate a real RCM partner from a login and a prayer.

How do you know it’s time to switch billing companies?

Not every billing problem is a biller problem. Before interviewing replacements, rule out the usual suspects on your side: intake collecting bad insurance info, clinical documentation missing medical necessity language, or UR deadlines getting blown because no one owns the calendar.

That said, the following patterns are hard to blame on anything but the vendor:

  • Days in AR creeping past 60 with no explanation and no action plan.
  • Denials sitting unworked past the appeal window — especially 90837 downcodes and medical necessity denials on residential and PHP claims.
  • You can’t get a clean, current aging report on demand.
  • Your dedicated account rep has changed three times in a year, or you no longer have one.
  • UR approvals are coming in late, short, or not at all, and your census is taking the hit.
  • Payer credentialing gaps are being discovered by your billers, not prevented.

Three or more of those, and the math almost always favors switching.

TL;DR: What does a clean billing company transition look like?

  • Don’t terminate first. Sign with the new biller, build the transition plan, then give notice — in that order.
  • Protect the open AR. Decide in writing who works claims with dates of service before the cutover. That single clause saves the most revenue.
  • Export everything before access is revoked. Aging, payer contracts, fee schedules, EOBs, ERA enrollments, patient ledgers, clearinghouse history.
  • Re-point ERAs and EFTs early. Payer portal updates take 30–45 days. Start day one, not cutover day.
  • Interview on specifics, not pitches. Ask about 90837 denial rates, UR turnaround, and how they handle timely filing on inherited claims.

What should you do before giving notice to your current biller?

The worst transitions happen when an operator fires the old company in frustration on a Friday and starts looking for a new one on Monday. By then, logins get shut off, AR goes cold, and claims past timely filing start dying quietly.

Before you send a termination letter, lock these down:

1. Read your current contract

Look specifically for the termination clause, notice period (usually 30–90 days), data return obligations, and any fees for claims worked after termination. Some contracts entitle the outgoing biller to a percentage of collections on claims they submitted, even if your new biller does the follow-up work. Know that number before you negotiate with anyone.

2. Pull a full data export now

Don’t wait until the relationship is tense. Request:

  • Current AR aging by payer and by date of service
  • A list of every claim submitted in the last 12 months with status
  • All EOBs and ERAs
  • Patient demographic and insurance files
  • Your payer contract copies and fee schedules
  • Clearinghouse enrollment records
  • Credentialing files and CAQH attestation history

Industry observation: the data you can get while the relationship is cordial is often five times what you’ll extract after you give notice.

3. Map your payer mix and open authorizations

Every active patient has an authorization with a start date, end date, and level of care. If that spreadsheet doesn’t already live in your EMR, build it before cutover. Dropped auths during transition are where census revenue leaks.

What questions should you ask a new behavioral health billing company?

Every RCM vendor’s sales deck says the same three things: experienced team, technology-driven, dedicated support. None of that is diligence. Ask questions that force specifics.

On billing performance

  • What’s your average days in AR for residential, PHP, and IOP clients?
  • How do you handle 90837 downcodes to 90834? What’s your appeal success rate?
  • Walk me through your denial workflow. Who touches a denial on day one, and what’s the turnaround to appeal?
  • How do you handle single case agreements and out-of-network negotiations?

On utilization review

  • Do you do concurrent UR in-house, or subcontract it?
  • What’s your average turnaround from clinical handoff to payer submission?
  • How do you handle peer-to-peers? Does your UR team coordinate them or does that fall back on my medical director?

If the answer to UR questions is vague, that’s a real warning sign. A strong utilization review process is the difference between a full census and a discharge-heavy month.

On the transition itself

  • Who works the open AR from the previous biller, and how is that scoped?
  • What’s your onboarding timeline — when does the first clean claim go out under you?
  • How do you handle claims that were denied before you took over but are still within appeal window?
  • What reporting will I get in the first 30, 60, and 90 days?

On people and accountability

  • Who is my named point of contact and what’s their direct line?
  • How many accounts does that person carry?
  • What happens when they’re out — who picks up?

A real answer sounds like “Maria is your account manager, she carries 8 facilities, her backup is Jon, here are both their cells.” A bad answer is “you’ll have access to our support team.”

How do you protect open AR during a billing transition?

This is where most money is lost, and most of it is preventable with one well-written paragraph in your transition plan.

Decide — in writing, signed by both billers if possible — who owns claims by date of service. The cleanest split looks like this:

  • Outgoing biller continues to work claims with dates of service before the cutover date for 60–90 days, on a reduced percentage or flat fee.
  • New biller owns everything from the cutover date forward, plus any claim the outgoing biller has not touched in 30 days.
  • Appeals on pre-cutover denials go to whichever party has the bandwidth and documentation, agreed case by case.

If the outgoing relationship is too far gone for that arrangement, plan for the new biller to inherit everything and price it accordingly. Expect a temporary dip in collections in months two and three — that’s normal, not a red flag, as long as the aging report starts compressing by month four.

What does the first 90 days with a new biller actually look like?

A realistic timeline for a mid-sized residential and PHP operation:

Days 1–15

Data migration. EMR integration or file feeds established. Payer portal access transferred or new logins created. ERA and EFT re-enrollment submitted to every payer — this alone is a 30–45 day process with some Medicaid MCOs, so starting day one matters. Credentialing and payer enrollment gaps get identified and flagged.

Days 16–45

First clean claims go out under the new biller. Initial aging cleanup on inherited AR begins. You should be getting weekly reports by week three, not monthly. Any authorization gaps from the transition are closed.

Days 46–90

Denial rates stabilize, AR days start trending down on post-cutover claims, and recovery on aged AR shows up in cash. If by day 90 your new biller can’t show you a side-by-side of inherited aging vs. current aging, that’s a conversation to have immediately.

What are the most common billing transition mistakes?

  • Giving notice before signing a new contract. Now you’re negotiating from weakness with every vendor who finds out.
  • Assuming the old biller will hand over data cleanly. They might. Don’t bet AR on it.
  • Not updating ERAs and EFTs fast enough. Payments keep flowing to the old biller’s bank account or clearinghouse, and clawing them back is painful.
  • Letting authorizations lapse during the handoff. The new UR team needs the active auth list on day one, not day fifteen.
  • Signing a long contract with the new biller to get a discount. A 90-day out clause is worth more than a 10% rate cut.

Frequently Asked Questions

How long does it take to switch behavioral health billing companies?

Plan on 60–90 days from signing with a new biller to a fully stable state. The first clean claims usually go out within the first 2–3 weeks, but ERA and EFT re-enrollments with payers often take 30–45 days, and inherited AR cleanup runs through the first 90 days.

Who works my open AR when I switch billers?

That should be decided in writing before you give notice. The cleanest arrangement is the outgoing biller continues working pre-cutover claims for 60–90 days while the new biller handles everything from the cutover date forward. If the outgoing relationship is too strained, the new biller inherits all AR and prices accordingly.

What data do I need to export from my current billing company?

At minimum: current AR aging by payer, 12 months of claim history with statuses, all EOBs and ERAs, patient demographic and insurance files, payer contracts and fee schedules, clearinghouse enrollment records, and credentialing and CAQH files. Pull this while the relationship is still cordial.

Will my collections drop during the transition?

Usually yes, temporarily — most commonly in months two and three as old claims age out and new claims are still moving through first-payer cycles. A competent new biller should show aging compression and improving collections by month four.

Should I give notice to my current biller before signing a new one?

No. Sign the new contract, build the transition plan, then give notice. Terminating first leaves you negotiating from weakness and at risk of losing access to data and portals before you’re ready.

What’s the single most important question to ask a new behavioral health biller?

Ask them to walk through their denial workflow in specifics — who touches a denial on day one, what the turnaround is to appeal, and what their success rate looks like on common behavioral health denials like 90837 downcodes and medical necessity denials on residential. Vague answers here predict vague performance.
