HCPCS H0015: Intensive Outpatient Alcohol and/or Drug Services

The code is used across outpatient behavioral health settings and is an important mechanism for classifying and billing structured, non-residential addiction treatment nationally.

Readers will find a concise profile of what H0015 covers clinically and administratively, common payer considerations and level‑of‑care indicators, and comparisons to closely related service codes used for intensive outpatient and therapeutic behavioral services. The publication highlights coding context, typical sites of service and billing practice notes, model encounter structures, and crosswalks to related HCPCS and service‑level codes.
