What G2088 covers
G2088 captures additional time spent providing office-based treatment for opioid use disorder during a calendar month. The monthly service may include care coordination, individual or group psychotherapy and counseling, and treatment-plan work. Physicians and other qualified practitioners furnishing this care in an office setting use the code when the documented treatment time extends beyond the amount represented by the primary monthly service.
Report G2088 only with the applicable primary code, G2086 for the initial month or G2087 for a subsequent month. Each unit represents an additional 30 minutes; documentation should identify the treatment activities and support the additional time. CMS treats payment for this add-on as part of the primary procedure’s global period. It is not a stand-alone monthly treatment code.
This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
