Clinical & Coding Specifications
Clinical Context
A 38-year-old patient with a history of alcohol dependence presents to an inpatient behavioral health unit with escalating withdrawal symptoms including tremor, agitation, and autonomic instability.

The clinical workflow includes initial nursing triage and medical evaluation, baseline vital signs and labs, medication-assisted withdrawal management as needed, psychosocial assessment by an addiction counselor or psychologist, daily progress reviews by the treatment team, and discharge planning to an outpatient treatment program or higher level of care when medically stable.
