Addiction Medicine Billing Services for MOUD, OTP Bundles, Denials, and AR Recovery
Addiction medicine billing is the specialty revenue cycle process for medications for opioid use disorder (MOUD), opioid treatment program (OTP) weekly bundles, and office based substance use disorder treatment. Medicare pays OTPs through seven-day episode bundles built around the medication pathway — methadone, oral or injectable buprenorphine, or naltrexone — while office based MOUD practices bill separate monthly codes (G2086, G2087, G2088) through professional claims. Using an OTP code outside an enrolled opioid treatment program, or mixing up weekly and monthly billing periods, is the single most common cause of MOUD claim denials. ClaraRCM manages addiction medicine billing for OTPs, office based practices, and behavioral health organizations across all 50 states with a 97% clean claim rate.
ClaraRCM provides addiction medicine billing services for U.S. opioid treatment programs, office based MOUD practices, behavioral health groups, and integrated care organizations. Our team manages eligibility, OTP weekly bundles, office based monthly SUD services, counseling, toxicology, take home medication add ons, payment posting, denials, and aging AR.

What Is Addiction Medicine Billing, and Why Do MOUD Claims Get Denied?
In brief: Addiction medicine billing converts MOUD, counseling, therapy, toxicology, intake, assessment, care coordination, and recovery support into payer compliant claims. Revenue is lost when the program setting, episode period, code family, medication pathway, documentation, consent, payer rule, or claim format does not match the service delivered.
Addiction medicine billing is the specialty revenue cycle process for substance use disorder treatment. It connects patient eligibility, program enrollment, diagnosis, medication pathway, weekly or monthly service evidence, HCPCS and CPT selection, claim submission, payment posting, denials, and AR follow up.
Medicare OTP claims use weekly episode bundles, while office based SUD treatment uses different professional code families and monthly service requirements. Commercial plans and state Medicaid programs can apply their own authorization, medication, counseling, toxicology, and network rules.
Our team validates the program, clinician, payer benefit, consent, diagnosis, medication, episode dates, counseling, toxicology, add on services, claim format, remittance, and outstanding balance before revenue is left unresolved.

Opioid Treatment Program Billing vs Office Based MOUD Billing
Both models treat substance use disorders, but Medicare uses different enrollment, code, claim, service period, medication, and documentation rules. Accurate billing begins by identifying the setting and covered treatment model.
| Factor | OTP Billing | Office Based MOUD Billing |
|---|---|---|
| Eligible organization | Medicare enrolled and SAMHSA certified opioid treatment program | Eligible physician or nonphysician practitioner in an office based setting |
| Core billing period | Seven day episode of care | Calendar month |
| Common codes | G2067, G2068, G2069, G2073, G2074, and supported add ons | G2086, G2087, and G2088, plus other separately supported professional services |
| Medication treatment | Covered within the applicable OTP medication bundle | Medication may be prescribed and covered through the applicable pharmacy benefit |
| Claim focus | POS 58 or applicable institutional OTP claim structure | Professional office claim structure |
| Core documentation | Episode service, medication pathway, counseling, toxicology, and add on support | Treatment plan, care coordination, therapy, counseling, and monthly time |
| Common billing risk | Overlapping episodes, wrong medication bundle, or unsupported add on units | Missing time, plan, coordination, or use of an OTP code outside an enrolled OTP |

What is addiction medicine billing?
Addiction medicine billing is the revenue cycle process for substance use disorder evaluation, medications for opioid use disorder, counseling, therapy, toxicology, care coordination, and follow up. It connects the treatment setting, payer enrollment, diagnosis, service period, code family, documentation, claim submission, payment posting, denials, and accounts receivable.
What is the difference between MOUD and MAT billing?
MOUD billing focuses specifically on medications for opioid use disorder, including methadone, buprenorphine, and naltrexone treatment pathways. MAT is an older and broader term that combines medication with counseling and behavioral services. Payers and regulations may use either term, so claims should follow the exact covered benefit and code family.
How does Medicare pay opioid treatment programs?
Medicare pays enrolled opioid treatment programs through weekly bundled payments. The selected base code depends on the medication or non drug pathway. The bundle can include dispensing, administration, counseling, therapy, toxicology, intake, assessment, and other covered services, with supported add on codes for qualifying additional work.
What is the difference between G2067 and G2068?
G2067 is the Medicare weekly OTP bundle that includes methadone treatment. G2068 is the weekly bundle for oral buprenorphine treatment, including eligible buprenorphine and naloxone combination products. Each code generally represents one seven day episode and should not be duplicated for the same patient and period.
How is OTP billing different from office based MOUD billing?
OTP billing uses Medicare weekly episode codes and requires an enrolled opioid treatment program. Office based treatment uses professional claims and may use monthly SUD bundle codes G2086, G2087, and G2088 when their service and time requirements are met. Clinicians cannot use OTP codes for ordinary office based treatment.
Can counseling be billed separately from a Medicare OTP bundle?
Routine substance use counseling and individual or group therapy are included in the weekly OTP bundle. G2080 may be reported for each additional thirty minutes when medically necessary counseling or therapy substantially exceeds the amount in the individualized treatment plan. The additional service must be documented and linked to the qualifying base bundle.
How are take home methadone and buprenorphine supplies billed?
G2078 reports up to seven additional days of take home methadone, while G2079 reports up to seven additional days of oral buprenorphine. Each is an add on to the corresponding weekly bundle. Medicare limits frequency and does not allow overlapping take home dates with medication periods already represented by a weekly bundle.
What is the difference between G2086 and G2087?
G2086 describes the first calendar month of office based SUD treatment and requires treatment plan development, care coordination, and at least seventy minutes of qualifying services. G2087 describes a subsequent month and requires care coordination plus at least sixty minutes of qualifying office based treatment services.
Which claim details are important for Medicare OTP billing?
Professional OTP claims commonly require POS 58, the applicable HCPCS code, the date for add on services, an OUD diagnosis, the ordering or prescribing professional NPI, and the organizational NPI as billing provider. Institutional OTP claims use the applicable type of bill, revenue code, condition code, and diagnosis information.
How does 42 CFR Part 2 affect addiction medicine billing?
42 CFR Part 2 protects substance use disorder patient records. Billing and payment workflows must control consent, access, disclosure, notices, and secure handling of Part 2 information. The updated final rule aligned several provisions with HIPAA and required regulated organizations to comply with the applicable changes by February 16, 2026.
Why are MOUD and addiction medicine claims denied?
Common causes include using an OTP code for office based care, overlapping weekly episodes, missing OUD diagnosis support, incorrect POS or claim type, absent service evidence, unsupported take home units, duplicate counseling, payer authorization issues, medication policy differences, and incomplete coordination between clinical, pharmacy, counseling, and billing records.
Is outsourcing addiction medicine billing worth it?
Outsourcing can be valuable when a program needs specialized OTP, office based MOUD, behavioral health, toxicology, privacy, payer, denial, and AR expertise. The decision should compare vendor cost with missed weekly bundles, unbilled add on services, staffing gaps, underpayments, aging AR, compliance risk, and the quality of claim level reporting.
