Service Type: Behavioral health residential treatment

Typical Site of Service: Residential treatment program (non-hospital)

Clinical Context

A 28-year-old patient with a history of recurrent major depressive disorder (F33.9) and generalized anxiety disorder (F41.1) is referred by an outpatient psychiatrist to a non-medical residential treatment program for long-term behavioral health stabilization. The clinical workflow begins with an intake assessment by a licensed mental health clinician, development of an individualized treatment plan, daily group therapy, individual psychotherapy, medication management coordinated with the treating psychiatrist, and ongoing progress reviews. The program provides structured therapeutic services longer than 30 days without room and board billing; services are billed per diem using HCPCS Level II code H0019.
