    Clinical & Coding Specifications

    Clinical Context

    A 38-year-old patient with alcohol use disorder is enrolled in a residential addiction program that provides sub-acute detoxification services coded as H0012. The patient presents with acute alcohol withdrawal symptoms (tremor, diaphoresis, mild hypertension) and co-occurring major depressive disorder (F32.9) and generalized anxiety disorder (F41.1). The clinical workflow begins with an intake assessment by a licensed clinician (mental health counselor or clinical social worker) documenting substance use history, withdrawal risk, and comorbid psychiatric diagnoses. A medical evaluation by program nursing staff and, when indicated, collaboration with a prescribing practitioner occurs to determine need for benzodiazepine taper or other symptomatic medication. The program provides structured monitoring, psychosocial interventions, group education, and brief individual counseling focused on stabilization. Daily progress notes document vital signs, withdrawal scale scores, medication administration, and readiness for transition to outpatient treatment. Discharge planning includes referral to outpatient behavioral health services and coordination with payors such as Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, BUCA, and Medicare for continued care authorization and claims submission.
