Clinical & Coding Specifications
Clinical Context
A typical patient is an adult with severe, persistent behavioral health needs such as chronic major depressive disorder with suicidality, treatment-resistant bipolar disorder, or severe post-traumatic stress disorder who requires a structured, non-acute residential treatment environment for longer than 30 days. The patient is admitted after an outpatient psychiatric crisis or discharge from an acute inpatient psychiatric unit when acute safety concerns have stabilized but ongoing intensive psychosocial, medication, and rehabilitative services are needed.
Admission workflow: initial intake by a multidisciplinary team (psychiatrist, therapist, nursing), comprehensive biopsychosocial assessment, formulation of a residential treatment plan with daily therapeutic programming, medication management, and periodic multidisciplinary reviews. Nursing staff provide daily monitoring and coordination with community supports. Discharge planning begins at admission and includes step-down referrals (outpatient therapy, intensive outpatient program, or community-based resources). Billing uses per diem reporting for room, board, and bundled behavioral health services under T2048. Documentation includes signed consent, treatment plan, progress notes, daily nursing notes, medication administration records, and multidisciplinary team meeting summaries.
