HCPCS Code H0018: Behavioral Health; Short-Term Residential

H0018 covers short-term residential treatment program options designed for a targeted population such as individuals with acute mental health, alcohol and or drug issues. A licensed program will determine eligibility and ensure the appropriate level of care, which may include group counseling, brief intervention, or referral service for ongoing support.

It differs from a treatment program without room or a residential treatment program without board, which may be delivered in an ambulatory setting or through intensive outpatient care. H0018 provides structured, 24-hour support rather than non direct contact or external activities geared toward prevention.

Claims must specify the number of covered days (per diem) and comply with payer guidelines, including Medicaid services and some commercial insurers. Note: Medicare generally does not cover residential treatment programs billed under H0018.
