12-Step Individual Psychotherapy Procedure Overview

Procedures in this group involve individual psychotherapy specifically using a 12-step approach for substance abuse treatment, delivered to a single patient to modify addictive behaviors and support recovery. These interventions are non-anatomical and focus on behavioral, cognitive, and psychosocial techniques rather than a physical body system. Accurate coding ensures inpatient records reflect the therapeutic modality provided and supports appropriate case mix assignment and reimbursement.

Typical Clinical Scenarios

A 34-year-old patient admitted after medically supervised detoxification for severe alcohol dependence with persistent cravings and high risk of relapse. During the inpatient stay, the treatment team documents daily one-on-one psychotherapy sessions using a structured 12-step approach to address addictive behaviors and support transition to outpatient recovery programs. The 12-step individual psychotherapy is provided as the primary behavioral intervention to prepare the patient for continued sobriety after discharge. Typical codes: HZ53ZZZ
A 22-year-old patient presents to the emergency department after an opioid overdose and is admitted for stabilization and observation following reversal. Once medically stable, the patient receives individualized 12-step psychotherapy during the inpatient stay to address substance use triggers, increase motivation for recovery, and plan follow-up care. The documented one-on-one 12-step sessions are part of the acute hospitalization’s substance abuse treatment plan. Typical codes: HZ53ZZZ
A 46-year-old patient with a history of recurrent stimulant misuse is readmitted for escalating relapse despite prior treatments. As part of the inpatient readmission, clinicians provide intensive individual psychotherapy using a 12-step model to modify entrenched addictive behaviors and to revise the personalized relapse-prevention plan. The focused one-on-one 12-step intervention is documented as the therapeutic modality for this repeat inpatient episode. Typical codes: HZ53ZZZ
