About G2088: Additional office-based opioid treatment time
Reports each additional 30 minutes of office-based opioid use disorder treatment during a calendar month beyond the time represented by the primary monthly service.
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.
