HCPCS Level II code G2086 designates comprehensive office-based treatment for opioid use disorder (OUD) delivered during the first calendar month, requiring at least 70 minutes of services including treatment planning, care coordination, and individual and group therapy. The code is important nationally as payers and providers expand outpatient OUD care options and align billing with time-intensive initial-month interventions. Coverage and payment policies for this service influence access to evidence-based OUD treatment in community settings and affect practice workflows for behavioral health and primary care clinicians.
Key payers covered in this brief include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of what this code represents, typical sites of service, and the clinical services it encompasses. The analysis highlights benchmarking and policy-relevant context for payers and provider organizations, including how time-based reporting in the initial month may affect billing, care coordination, and multidisciplinary delivery models. This publication also summarizes common modifiers and other administrative considerations where available. Data not available in the input will be identified explicitly in relevant sections.

Clinical & Coding Specifications
Clinical Context
A 32-year-old patient with moderate-to-severe opioid use disorder presents to an office-based medication-assisted treatment (MAT) program for initial management. The clinician performs an intake visit that includes a comprehensive assessment of substance use history, medical and psychiatric comorbidities, medication reconciliation, and risk assessment for overdose. A multidisciplinary team member (licensed clinician or counselor) develops an individualized treatment plan, initiates buprenorphine treatment when appropriate, and arranges care coordination with behavioral health services and community supports. Over the first calendar month the patient receives combined individual behavioral therapy and weekly group counseling sessions, with the clinician documenting at least 70 minutes of total face-to-face treatment time across visits in that month. Typical workflow steps include triage and medical evaluation, medication induction or stabilization, individual therapy, group counseling, care coordination (for social supports, pharmacy, and specialty referrals), and documentation of time and treatment plan updates for billing under G2086.
