Behavioral Health Billing Services
Behavioral health programs bill differently from a typical therapy practice. Substance use treatment, intensive outpatient (IOP), partial hospitalization (PHP) and ABA therapy each have their own codes, authorization rules and documentation standards, and many of their claims go on a UB-04 instead of a CMS-1500.
Prospect Healthcare Solutions handles billing for these programs from start to finish: eligibility and authorizations, coding, claim submission, denial follow-up and payment posting. We also work within the extra privacy rules that apply to substance use records under 42 CFR Part 2.

Behavioral Health Programs We Bill For
- Substance use disorder (SUD) treatment: outpatient counseling, medication-assisted treatment (MAT) and opioid treatment programs.
- Intensive outpatient programs (IOP): mental health and SUD programs. Medicare covers IOP in hospital outpatient departments, community mental health centers, FQHCs, RHCs and opioid treatment programs when the care plan calls for at least 9 hours of services a week.
- Partial hospitalization programs (PHP): structured day programs billed by hospitals and community mental health centers.
- ABA therapy: assessments, technician-delivered treatment, protocol modification and caregiver training for autism services.
- Community mental health centers and multi-program clinics that run several of these services under one roof.
We work inside your existing EHR and practice management system, track every claim and manage claim denials so revenue doesn’t stall.
Why Choose Our Behavioral Health Billing Services?

Expertise in Behavioral Health Billing
We focus on behavioral health program billing (SUD, IOP, PHP and ABA) and know the payer rules that make these claims different. That means cleaner submissions, fewer denials and steadier collections.

Complete Revenue Cycle Solutions
We manage all stages of your revenue cycle, such as the verification, coding, filing of claims, and posting the payment. We have a lean process that reduces delays, maximizes collections, and requires less work on administration. Through effective management of every detail, we assist your behavioral health practice to have a reliable cash flow and financial health.

Denial Management
We also actively avoid claim rejection as we detect and address possible problems at their inception. In case of denials, our specialists promptly research, rectify, and remit claims. Our priorities are to keep our clean-claim rates high and to enhance the speed of reimbursement to make sure that your practice does not lose revenue and gets the maximum financial compensation.

Accurate Coding
Our coders work with HCPCS H-codes, UB-04 revenue codes and ABA CPT codes, so each service is billed the way your payer contract expects and backed by the right documentation.

Transparent Reporting
We offer elaborate financial reports and analytics, which give you a complete picture of your revenue performance. Our open system assists you in claim tracking, collection tracking as well as making business decisions that are data-driven. You can always get to know how your practice is financially performing with precise and straightforward reporting.

Reliable Support
Our communication with the clients has been given high priority, and we are providing dedicated support at each stage. Our staff responds to your questions promptly, clears billing questions, and provides smooth operations. We think in the establishment of enduring relationships based on a reliable service, which will assist your behavioral health practice to operate effectively and profitably.
Billing Rules by Program Type
SUD services. Medicaid and many state-funded programs use HCPCS H-codes, such as H0001 (alcohol and/or drug assessment), H0004 (behavioral health counseling, per 15 minutes), H0005 (alcohol and/or drug group counseling) and H0015 (alcohol and/or drug intensive outpatient). Commercial plans and Medicare often expect CPT or facility coding instead, so we match codes to each payer’s contract. Medical necessity is usually reviewed against ASAM level-of-care criteria.
IOP and PHP. Facility claims go on the UB-04 with revenue codes such as 0905/0906 (intensive outpatient, psychiatric / chemical dependency) and 0912/0913 (partial hospitalization). We track per-diem versus per-service billing, weekly hour requirements and concurrent reviews so authorizations don’t lapse mid-stay.
ABA therapy. ABA uses CPT 97151–97158, billed in 15-minute units, plus Category III codes 0362T and 0373T for destructive-behavior protocols. We check unit caps, technician and supervising-analyst credentials, and authorized hours before every claim. Revisions to the adaptive behavior codes have been proposed for 2027, and we will update your setup if they are finalized.
Every program also gets full revenue cycle management: verification, coding, claims, denials and payment posting.
Opioid Treatment, Drug Testing and Peer Support Rules
Substance use programs have their own Medicare and Medicaid billing models for medication treatment, drug testing and peer support. These are the rules our revenue cycle management team handles for them:
Opioid treatment program bundles
What it means: Medicare pays opioid treatment programs a weekly bundle (G2067–G2080) based on the medication given, with add-on codes for take-home doses and extra counseling.
How we handle it: We bill the bundle that matches the medication and week, and add the add-on codes only when the service is documented.
Office-based opioid use disorder treatment
What it means: Practices that prescribe buprenorphine in the office can bill monthly bundled codes (G2086–G2088) for care management and counseling, alongside separate E/M visits.
How we handle it: We track minutes each month and bill the bundle only when the time threshold is met.
Drug testing in treatment programs
What it means: Presumptive tests (80305–80307) and definitive tests (G0480–G0483 for Medicare) have frequency limits, and payers expect the number of drug classes tested to match the patient’s history and treatment plan.
How we handle it: We check the order and the treatment plan for each test, and bill the definitive tier that the documented drug classes support.
Peer support services
What it means: Many Medicaid programs pay for peer support (H0038) only when it is delivered by a state-certified peer specialist under a treatment plan.
How we handle it: We confirm the peer specialist’s certification and the treatment plan before billing.
A Common Behavioral Health Denial and How We Fix It
Example: IOP days denied after the authorization ran out
The denial. A patient’s intensive outpatient program continues past the approved number of days, and the extra days are denied with CARC 198 (authorization exceeded).
How we fix it:
- Check the approval. We compare the authorized days and dates with the days billed.
- Request a retro review. Where the payer allows it, we request a review of the extra days with the progress notes and level-of-care assessment.
- Appeal. If the review is denied, we appeal with the clinical record showing why the patient needed continued care.
- Prevent the next one. We track remaining authorized days and schedule concurrent reviews before the approval ends.
Example: a definitive drug test denied for medical necessity
The denial. A definitive drug test covering 22 or more drug classes (G0483) is denied with CARC 50 (not medically necessary).
How we fix it: we check the order and the treatment plan for the reason each drug class was tested. If the record supports fewer classes, we correct the claim to the matching tier (G0480–G0482). If it supports all of them, our denial management team appeals with the plan. We then work with the program on a testing policy that matches payer rules.
HIPAA and 42 CFR Part 2 Compliant Billing
Substance use treatment records carry stricter privacy rules than other health records. Under the updated 42 CFR Part 2 rule, with a compliance date of February 16, 2026, patients can sign a single consent for treatment, payment and health care operations, and Part 2 breaches now follow HIPAA-style notification and penalties.
We bill within those limits, sharing only the information each claim needs and working in encrypted, access-controlled systems. The same HIPAA safeguards apply to every behavioral health and ABA account we handle.
Behavioral Health Billing FAQs
What does behavioral health billing cover?
Billing for substance use treatment, intensive outpatient programs (IOP), partial hospitalization programs (PHP), ABA therapy and community mental health centers. For outpatient therapy and psychiatry practices, see our mental health billing services.
How is behavioral health billing different from mental health billing?
Behavioral health programs often bill as facilities on the UB-04 with revenue codes, use HCPCS H-codes for Medicaid and state-funded services, bill per diem or per program day, and face level-of-care reviews. Substance use records also fall under 42 CFR Part 2.
Does Medicare cover intensive outpatient programs?
Yes. Medicare Part B covers IOP services in hospital outpatient departments, community mental health centers, FQHCs, RHCs and opioid treatment programs when the care plan calls for at least 9 hours of services a week. Patients generally pay 20% coinsurance after the Part B deductible.
Which CPT codes are used for ABA therapy?
ABA services use CPT 97151–97158, billed in 15-minute units, plus Category III codes 0362T and 0373T for destructive-behavior protocols. Revisions to these codes have been proposed for 2027.
What is 42 CFR Part 2 and does it affect billing?
42 CFR Part 2 protects substance use disorder treatment records. The updated rule, with a compliance date of February 16, 2026, allows a single patient consent for treatment, payment and health care operations, so billing must follow the consent on file and share only what each claim needs.
