Summary & Overview
HCPCS G2172: All-Inclusive Opioid Use Disorder Treatment Payment
HCPCS Level II code G2172 designates an all-inclusive payment for highly coordinated and integrated opioid use disorder (OUD) treatment services provided under a demonstration project. The code matters nationally as policymakers and payers explore payment models that support comprehensive OUD care through bundled, demonstration-based reimbursement structures aimed at improving access, care coordination, and outcomes.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of what the code represents, how it aligns with integrated OUD treatment service delivery, and the national policy context driving demonstration payments. The publication summarizes available benchmarks and payment model characteristics, clarifies typical sites of service and service components captured by the all-inclusive payment, and highlights implications for coverage and care coordination under demonstration arrangements.
This summary is national in scope and focuses on the clinical and payment purpose of the code, the payers engaged in analysis, and the types of information readers can expect: descriptive benchmarks of bundled payment design, recent policy updates affecting demonstration projects, and clinical context for highly coordinated OUD treatment.
Billing Code Overview
HCPCS Level II code G2172 represents an all-inclusive payment for services related to highly coordinated and integrated opioid use disorder (OUD) treatment services furnished for a demonstration project. The code is intended to capture bundled care that covers the range of activities involved in delivering intensive, coordinated OUD treatment under a structured demonstration model.

Clinical & Coding Specifications
Clinical Context
A typical patient is a 32-year-old adult with moderate-to-severe opioid use disorder presenting to a multidisciplinary outpatient addiction treatment program participating in a demonstration project. The patient is referred after an emergency department visit for opioid overdose and receives an intake assessment by a licensed clinician, medication evaluation by an addiction medicine prescriber, initiation of buprenorphine or methadone as indicated, counseling by a behavioral health clinician, coordinated care planning, medication monitoring (including urine drug testing), care management for social needs (housing, transportation, benefits), and regular team case conferences to adjust treatment. Services are delivered across integrated settings including outpatient clinic visits, telehealth encounters, community outreach, and coordinated referrals to social services. The billing code G2172 represents an all-inclusive payment covering these highly coordinated and integrated opioid use disorder treatment services furnished over the demonstration project episode of care, rather than a single discrete procedure.
