TL;DR
G2011 is a Level II code from the G section (procedures and professional services, temporary), in use since 2019: "Alcohol and/or substance (other than tobacco) misuse structured assessment (e.g., audit, dast), and brief intervention, 5-14 minutes". National PFS payment for G2011 is $17.37 in an office and $14.70 in a facility (October 2026), built from 0.33 work, 0.16 practice-expense and 0.03 malpractice RVUs at $33.4009 per RVU. Qualifying APM participants get $17.46 at $33.5675. CMS caps G2011 at practitioner 1 (MAI 2, Code Descriptor / CPT Instruction); hospital outpatient 1 (MAI 2, Code Descriptor / CPT Instruction) units per day in the 2026 Q4 MUE tables. In the NCCI PTP files v323r0 G2011 appears in 103 practitioner pairs as column 2 and 8 as column 1 (most often with 90791, 90792, 90832), and in 103 hospital outpatient pairs as column 2 and 5 as column 1. G2011 appears in no active LCD or billing and coding article, so coverage follows HCPCS coverage code C (carrier judgment, so the Medicare contractor decides coverage) and any NCD. HCPCS record: BETOS M1B (office visits - established); pricing indicator 13; type of service 1 (medical care). 2 other active codes open with "Alcohol and/or substance"; related codes: G0397, G0396, G2010, G2014.

Physician fee schedule (RVU26D)
Status A: active: paid separately under the physician fee schedule when covered. Global period XXX (global surgery concept does not apply); PC/TC indicator 0 (physician service; the professional/technical split does not apply).

| Practice expense RVU | 0.16 | 0.08 |
| Malpractice RVU | 0.03 | 0.03 |
| Total RVUs | 0.52 | 0.44 |

Medically Unlikely Edits for G2011
CMS caps G2011 at practitioner 1 (MAI 2, Code Descriptor / CPT Instruction); hospital outpatient 1 (MAI 2, Code Descriptor / CPT Instruction) units per day in the 2026 Q4 MUE tables. The practitioner MUE is a date-of-service policy edit: units above the limit deny even when split across lines, and appeals rarely succeed.
| Setting | MUE (units/DOS) | MAI | CMS rationale |
|---|---|---|---|
| Practitioner services | 1 | 2 Date of Service Edit: Policy | Code Descriptor / CPT Instruction |
| Facility outpatient hospital | 1 | 2 Date of Service Edit: Policy | Code Descriptor / CPT Instruction |
The MUE lookup for G2011 shows every setting next to any other code on the same claim.
NCCI edits and add-on rules
In the practitioner PTP file v323r0, G2011 is the column-2 (bundled) code in 103 active pairs, 90% of which allow a modifier and the column-1 code in 8 (25% modifier-allowed); 132 earlier pairs have been deleted. CMS's most frequent rationale for the bundled pairs: Standards of medical/surgical practice.
