Clinical & Coding Specifications

Clinical Context

A typical patient is an adult court-ordered or probation-referred individual adjudicated for a sexual offense who requires structured treatment as part of sentencing, supervision, or civil commitment. The service H2029 is delivered as a per diem program entry for specialized sexual offender treatment focusing on risk assessment, relapse prevention, cognitive-behavioral interventions, victim empathy work, and community safety planning. The clinical workflow begins with intake and multidisciplinary evaluation (psychiatric, psychological, and social history), completion of standardized risk assessment instruments, development of an individualized treatment plan, and assignment to daily group and individual therapy sessions. Documentation includes daily attendance, treatment goals, progress notes, risk monitoring, urine drug screens if indicated, and coordination notes for probation/parole or court liaisons. Typical sites of service are residential treatment facilities, secure outpatient programs with daily attendance requirements, correctional treatment units, or civil commitment hospitals providing structured per diem care. Services are billed per diem using H2029 for each day the patient receives the sexual offender treatment program.
