Summary & Overview
HCPCS H0023: Alcohol and/or Drug Outreach
HCPCS Level II code H0023 represents alcohol and/or drug outreach services delivered in community settings to engage individuals with substance use needs. As a behavioral health outreach code, H0023 supports initial contact, engagement, brief intervention, and linkage to continuing care—functions that are central to population health strategies and efforts to reduce barriers to treatment nationally. The code matters because outreach services are a key component of integrated behavioral health and public health responses to substance use disorders.
Key payers covered include Aetna, Blue Cross Blue Shield, Cigna Health, and UnitedHealthcare. Readers will find a concise overview of clinical context for outreach services, common co-occurring behavioral health diagnoses typically associated with outreach encounters, and how H0023 relates to neighboring behavioral health codes used for assessment, service planning, crisis intervention, and community supports. The publication outlines common modifiers and practitioner taxonomies used alongside the code and highlights related procedure codes to clarify service differentiation and billing pathways.
This summary equips payers, practice managers, and behavioral health clinicians with a focused reference on the purpose and clinical role of H0023, common sites of service, and the service types most often associated with alcohol and/or drug outreach.

Clinical & Coding Specifications
Clinical Context
A 34-year-old patient with a history of bipolar disorder presents to a Community Mental Health Center (Place of Service 53) and is not currently engaged in office-based treatment. A community outreach specialist conducts an in-person visit at the patient’s home or another community location to engage the patient, assess substance use risk, provide brief motivational engagement, and connect the patient to ongoing behavioral health services. The outreach specialist documents engagement attempts, barriers, brief interventions, safety concerns, and referrals in the patient record. This service is billed using HCPCS Level II code H0023 and is provided as a behavioral health outreach service when performed by qualified staff such as a mental health counselor, clinical social worker, psychologist, psychiatry physician, or counselor.
