Clinical & Coding Specifications
Clinical Context
A 34-year-old adult with moderate to severe alcohol use disorder is discharged from an inpatient detoxification unit but requires structured, residential supportive services to maintain abstinence, receive counseling, and reintegrate into the community. The patient is admitted to a licensed halfway house that provides daily supervision, group counseling, relapse prevention services, medication monitoring, and linkage to outpatient treatment. The clinical workflow begins with an intake assessment documenting substance use history, mental health comorbidity screening, and a written plan of care. Daily services include supervised living, attendance at therapeutic group sessions, random urine drug testing as clinically indicated, medication administration or monitoring (e.g., for naltrexone or buprenorphine if applicable), and case management for employment and housing. Clinicians (licensed addiction counselors, social workers, primary care or psychiatry as needed) periodically reassess progress; utilization review determines per diem authorization under H2034. Discharge planning includes referral to outpatient therapy, community support groups, and coordination with payors for continued coverage of services.
