HCPCS Code H0017: Behavioral Health; Residential, Without Room and Board, Per Diem

## **What is a Behavioral Health Residential Treatment (without room and board)?** HCPCS code H0017 is defined as “Behavioral health; residential (hospital residential treatment program), without room and board, per diem.” This code is used to report structured, hospital-based residential behavioral health treatment provided to patients who require 24-hour clinical oversight and multidisciplinary care, while excluding lodging and meal costs from reimbursement. These services are billed on a daily basis (per diem) and represent only the clinical and therapeutic components of care, which are priced separately from housing or meals. Residential treatment under H0017 encompasses intensive, medically supervised programs designed for individuals with substance use disorders, mood disorders, or co-occurring psychiatric conditions. Covered services may include drug services, individual and group therapy, medication management, behavioral interventions, and continuous clinical monitoring within a hospital-affiliated or licensed behavioral health facility. Because H0017 specifies “without room and board,” facilities must bill accommodation and meal charges separately or through another funding source. H0017 applies to hospital-based or state-licensed residential behavioral health programs that meet behavioral health accreditation requirements and provide continuous, structured care consistent with medical necessity and payer-defined levels of care.

## **HCPCS code H0017 documentation requirements** Providers must maintain clear, complete clinical documentation to establish the medical necessity and scope of services delivered. Documentation should demonstrate that the intensity of care meets criteria for hospital residential treatment and complies with payer and licensing standards for substance use or equivalent behavioral health level. Documentation must include: - **Comprehensive intake and assessment**: Psychiatric, medical, and psychosocial evaluations justifying the need for hospital-level residential treatment. - **Individualized treatment plan**: Includes measurable goals, therapeutic interventions (e.g., individual/group therapy, medication management, psychoeducation), and expected outcomes. - **Daily service notes**: Record of all therapeutic, nursing, and medication management services delivered per diem. - **Progress and discharge summaries**: Describe treatment response, progress toward goals, and post-discharge recommendations. - **Qualified provider documentation**: All care must be delivered or supervised by licensed behavioral health professionals within a state-approved or hospital-accredited facility.

## **H0017 billing requirements** Because H0017 covers only the clinical component of residential treatment (not lodging), accurate billing requires adherence to payer-specific guidelines. - One per diem (one unit = one day of treatment). Do not bill multiple times per day. - Must be a hospital-affiliated or licensed residential program providing 24-hour supervision, therapy, and medical oversight. - Bill room and board separately if permitted (e.g., S9976) or ensure another payer covers it. - Medicare may reimburse H0017 for alcohol and drug abuse treatment services under specific benefit plans, though coverage is not automatic. It depends on local or national coverage determinations (LCDs/NCDs) and whether the facility qualifies under hospital outpatient or partial hospitalization benefit categories. - Many private insurers and Medicaid programs recognize H0017 for residential substance use or mental health treatment, often requiring prior authorization and documentation aligned with the American Society of Addiction Medicine (ASAM) or equivalent state criteria. Providers should verify eligibility, authorization requirements, and payer-specific clinical criteria before submitting claims to prevent denials for non-covered or incorrectly coded services.

Frequently asked questions

No. H0017 covers only clinical services. Room and board must be billed separately using revenue codes like S9976 or as directed on the facility UB-04 guidelines.

No. H0017 is strictly per-diem. A single service day equals one unit. Use the respective per-diem code (e.g., H0018 or H0019) depending on program type and duration.

It depends on the payer. In some state guides (e.g., New Mexico), no prior authorization is needed for initial clinical intervention. Still, it may be required if transitioning to a different American Society of Addiction Medicine (ASAM) level of care.
