HZ92ZZZ	Pharmacotherapy for Substance Abuse Treatment, Levo-alpha-acetyl-methadol (LAAM)

Typical Clinical Scenarios

A 38-year-old patient with long-standing opioid dependence is admitted for medically managed withdrawal and initiation of inpatient replacement therapy after failing outpatient programs. During the hospital stay, levo-alpha-acetyl-methadol is administered under monitored conditions to stabilize cravings and prevent relapse while psychosocial services are arranged. The procedure documents the specific pharmacotherapy provided as part of the inpatient addiction treatment plan. Typical codes: HZ92ZZZ
A 26-year-old presents to the emergency department with acute complications of opioid misuse and is subsequently admitted for intensive medical and behavioral stabilization. Once medically stabilized, the patient is started on levo-alpha-acetyl-methadol during the inpatient stay to manage withdrawal symptoms and transition to ongoing addiction treatment. The administration is recorded to capture the inpatient pharmacotherapy intervention used in the acute stabilization period. Typical codes: HZ92ZZZ
A 52-year-old patient already receiving outpatient replacement therapy is admitted for a medical complication unrelated to substance use but requires continuation of addiction pharmacotherapy during hospitalization. Clinicians continue the patient's levo-alpha-acetyl-methadol regimen to avoid withdrawal and ensure continuity of care while treating the acute medical issue. Documentation of the inpatient provision of the medication is used to reflect continuation of replacement pharmacotherapy during the hospital stay. Typical codes: HZ92ZZZ
