HCPCS Level II code G9621 documents that a patient was identified as an unhealthy alcohol user through a systematic screening method and received brief counseling. This preventive-intervention code reflects growing emphasis on screening, brief intervention, and referral to treatment (SBIRT) approaches in ambulatory care and primary care settings. Nationally, the code supports documentation of population health and behavioral health integration efforts and can affect quality measurement and coverage determinations.
Key payers covered in this summary include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The discussion highlights how payers recognize and reimburse brief behavioral interventions tied to documented screening results, and how use of the code interfaces with quality reporting and preventive care initiatives.

Clinical & Coding Specifications
Clinical Context
A 42-year-old male presents to a primary care clinic for an annual visit. During the visit, the patient completes a standardized alcohol screening instrument (for example, the AUDIT-C) administered by medical staff as part of the clinic’s systematic screening program. Responses indicate unhealthy alcohol use. The clinician performs a brief counseling intervention during the same visit, discussing the screening results, assessing readiness to change, providing brief advice to reduce drinking, and offering resources for follow-up or referral to specialized care. Documentation includes the screening tool used, the positive screening result, the content and duration of brief counseling, and any follow-up plan. Typical sites of service include outpatient primary care clinics, community health centers, and federally qualified health centers where routine preventive screening and brief intervention are integrated into workflow.
