How We Help

Why Behavioral Health Programs Choose Thrive

Thrive Medical Billing manages the revenue cycle for behavioral health and substance use disorder programs across every level of care. We verify behavioral health benefits before admission, secure and track prior authorizations through discharge, apply the correct HCPCS, revenue, and modifier combination for each payer, and submit clean claims on both institutional and professional claim forms. When a payer denies a claim for medical necessity or a lapsed authorization, our team writes the appeal and requests a peer-to-peer review. The result is a behavioral health billing partner that treats authorization and documentation as revenue protection, not paperwork.

Full-Cycle Support

What Our Behavioral Health Billing Team Manages

A behavioral health billing company earns its keep in the details. Our behavioral health revenue cycle management team handles every step, from claims to payment, for your program.

Eligibility & Benefit Verification

Confirming behavioral health and SUD benefits, visit or day limits, and which entity, not just which plan, is financially responsible before admission.

Prior Authorization & Concurrent Review

Requesting initial authorization for detox, residential, PHP, and IOP, then filing concurrent reviews before each authorization window closes.

Specialty Coding & Claim Scrubbing

Applying the correct H-code, S-code, G-code, or CPT code plus the credential, program, and telehealth modifiers each payer requires.

Institutional & Professional Claims

Filing UB-04 facility claims for program days alongside CMS-1500 claims for the attending physician’s or prescriber’s visits.

Denial Management & Appeals

Building medical necessity and parity-based appeals for level-of-care downgrades, lapsed authorizations, and documentation denials.

A/R Follow-Up & Aging Recovery

Working every claim past 30 days, not just the newest denials, so aged balances do not get quietly written off.

Patient Statements & Collections

Sending clear statements for deductibles, coinsurance, and out-of-network balances tied to single case agreements.

Payment Posting & Reconciliation

Posting ERA and EOB payments against the correct level of care and reconciling per-diem underpayments against the contracted rate.

Credentialing & Payer Enrollment

Enrolling facilities and prescribers with commercial payers, state Medicaid behavioral health plans, and Medicare OTP billing privileges.

Coding Reference

Behavioral Health CPT & HCPCS Code Reference

Behavioral health CPT codes and HCPCS ranges vary by level of care and by payer. Here is the coding landscape our behavioral health billers work in every day.

Assessment, Screening & Case Management

SUD assessments, treatment eligibility screening, lab drug screening, and monthly case management coordination.

Detoxification

Sub-acute, acute, ambulatory, and outpatient detox services across residential and outpatient settings.

Intensive Outpatient (IOP)

Per-diem IOP billing. H0015 is used for Medicaid and SUD programs, S9480 for commercial mental health IOP.

Medicare IOP Benefit

Bundled weekly Medicare IOP billing at CMHCs, FQHCs, RHCs, hospital outpatient departments, and OTPs.

Residential Treatment

Per-diem codes for short-term and long-term residential SUD and mental health treatment, ASAM levels 3.1 through 3.7.

Partial Hospitalization (PHP)

Medicaid per-diem billing (H0035) and Medicare component billing for occupational therapy, activity therapy, and group psychotherapy within a PHP day.

Opioid Treatment Program (OTP) Bundles

Methadone and buprenorphine dispensing bundled with counseling and toxicology testing, billed per seven-day episode.

Office-Based MAT (Non-OTP)

Monthly bundled opioid use disorder treatment for physicians and qualified practitioners billing outside an OTP setting.

Outpatient Psychotherapy

Time-based individual, family, and group psychotherapy codes used for outpatient behavioral health encounters.

Orthodontics

Psychological Testing

Test evaluation and administration codes used for diagnostic clarification during intake and treatment planning.

What is a level-of-care (LOC) authorization?

A level-of-care authorization is a payer's approval for a specific intensity of treatment, such as residential or PHP, tied to ASAM or payer-specific clinical criteria. It expires on a set date and has to be renewed through concurrent review before that date, or every day billed afterward is at risk of denial.

H-codes, S-codes, and G-codes: what's the difference?

H-codes are permanent HCPCS codes states use for Medicaid behavioral health and SUD services. S-codes are temporary codes commercial payers use when no CPT code fits, such as S9480 for IOP. G-codes are Medicare-specific, including the newer G0510/G0511 IOP benefit and the G2067–G2088 opioid treatment bundles.

Where Revenue Gets Lost

Where Behavioral Health Claims Break Down

These are the denial patterns that are specific to behavioral health and substance use disorder billing, not generic claim errors.

Authorizations Expire Mid-Treatment

Detox, residential, and PHP/IOP authorizations are approved in short windows. When concurrent review isn’t filed before the window closes, every day billed after expiration is denied, not just delayed.

Medical Necessity Is Proven Session by Session

A diagnosis alone doesn’t carry the claim. Payers expect each note to show why the patient still meets criteria for that level of care, and a vague progress note can trigger a retroactive denial across an entire admission.

The Same Code Needs Different Modifiers by Payer

H0015 billed with modifier HF for one Medicaid plan may need HH for another, and a missing credential modifier like HO or AJ causes an automatic denial regardless of documentation quality.

Facility and Professional Claims Split Two Ways

Program days go on a UB-04 institutional claim while the attending psychiatrist’s or prescriber’s visits go on a separate CMS-1500. Missing either half leaves revenue uncollected.

Step-Down Criteria Get Challenged

Reviewers increasingly ask why a patient hasn’t stepped down to a lower level of care, not just what happened in group that day, and treat a weak answer as grounds to deny continued stay.

Single Case Agreements Bring Their Own Denial Pattern

Many programs operate out-of-network for some payers. Single case agreements solve access but introduce coordination-of-benefits errors and balance-billing complications that general billers rarely handle correctly.

State Medicaid Carve-Outs Route Claims Elsewhere

Several states carve SUD residential care out to a separate behavioral health organization or local authority. Billing the medical plan on the card instead of the carve-out entity produces a denial that can take 45 to 90 days to resolve.

OTP and MAT Bundles Have Strict Timing Rules

Weekly opioid treatment bundles can’t be billed more than once every seven days, and injectable or implant codes carry four- and six-month reuse limits. Billing outside those windows triggers an automatic rejection.

Our Process

Our Path From Admission to Payment

Each step below exists because of a specific challenge above. This is how we keep behavioral health claims from stalling out.

Verify Behavioral Health Benefits Before Admission

Confirm active coverage, day and visit limits, and which entity (medical plan or carve-out) is financially responsible before the first day of treatment.

Secure and Track Every Authorization

File the initial authorization for the certified level of care, then set alerts well ahead of the expiration date so concurrent review goes out on time, every time.

Code and Scrub Every Claim Against Payer Rules

Apply the correct HCPCS, revenue, and modifier combination for that specific payer, then run the claim through scrubbing before it reaches the clearinghouse.

Submit Clean Institutional and Professional Claims

File UB-04 facility claims and CMS-1500 professional claims in parallel so provider revenue isn't waiting on facility revenue, or the reverse.

Appeal Every Denial With a Documented Reason

Build medical necessity and, where applicable, parity-based appeals, and request a peer-to-peer review rather than writing the balance off.

Follow Up Aging Claims and Report the Numbers

Work the full A/R bucket, not just fresh denials, and report denial rate, authorization lapses, and days in A/R broken out by level of care.

Why Thrive

The Thrive Difference for Behavioral Health Programs

Coders Who Live in H-Codes and Modifiers

Our behavioral health billers work HCPCS ranges, revenue codes, and payer-specific modifier stacks daily, not as one specialty among many.

Authorization Tracking Built for Renewal

We treat authorization as a recurring deadline, not a one-time approval, with concurrent review filed ahead of every expiration date.

Dual Claim-Form Fluency

We file UB-04 institutional claims and CMS-1500 professional claims side by side so facility and provider revenue move together.

HIPAA-Compliant, Start to Finish

Every step of eligibility verification, authorization, coding, and appeals follows HIPAA-compliant handling of protected health information.

Nationwide Payer & Medicaid Experience

We bill across commercial payers, state Medicaid behavioral health carve-outs, and Medicare OTP benefits nationwide, not one region's payer mix.

Denial Management That Doesn't Write Off

Aged claims and prior denials get worked, appealed, and tracked to resolution rather than absorbed as a routine cost of doing business.

FAQ

Behavioral Health Billing Questions We Get Asked Most

How much do behavioral health billing services cost?

Most behavioral health billing companies charge a percentage of monthly collections, and the rate depends on your levels of care, claim volume, and payer mix. Thrive quotes a custom fee schedule after a free revenue review rather than a flat rate, since a detox program and a residential-to-IOP continuum bill very differently.

How long does onboarding take?

Timelines vary by how many payers and levels of care your program bills for. We prioritize active admissions and open authorizations first so nothing gets missed during the transition, then move to full claims submission once credentialing and payer connections are verified.

Can you take over our existing AR and open authorizations?

Yes. We review open authorizations, aging claims, and any denials already in progress before taking over billing, so nothing falls through during the transition. Legacy A/R does not get abandoned. We work it alongside new claims until it is resolved.

Do you bill for detox, residential, PHP, and IOP, or only outpatient counseling?

We bill across the full continuum, including detox, residential treatment, partial hospitalization, intensive outpatient, medication-assisted treatment, and outpatient counseling, using the HCPCS codes, revenue codes, and modifiers each level and each payer requires.

How do you handle denials and appeals?

Every denial gets a reason-specific appeal, not a form letter. For medical necessity or level-of-care denials, we document why the patient met continued-stay criteria. For parity-eligible situations, we include a Mental Health Parity Act argument and request a peer-to-peer review when appropriate.

Is your billing process HIPAA-compliant?

Yes. Every stage of eligibility verification, authorization requests, coding, claims submission, and appeals follows HIPAA-compliant handling of protected health information, and our team is trained on behavioral health confidentiality rules including 42 CFR Part 2 for substance use records.

How do we track our billing numbers?

You get visibility into denial rate, authorization status, days in A/R, and revenue by level of care, so you can see where claims are getting stuck instead of waiting on a monthly summary to find out.

Do you work with programs in every state?

Yes. We bill nationwide, including state Medicaid behavioral health carve-outs and Medicare's opioid treatment program benefit, and our coders track how modifier and code requirements differ from one state's program to the next.
