Typical Clinical Scenarios

A middle-aged patient is admitted to an inpatient substance abuse program following acute alcohol withdrawal complicated by inability to maintain sobriety in outpatient treatment. During the inpatient stay, structured individual behavioral psychotherapy sessions are provided to address maladaptive drinking behaviors, triggers, and relapse prevention as part of the treatment plan. The behavioral individual psychotherapy procedure is performed to modify learned behaviors and support recovery while medically stabilized. Typical codes: HZ51ZZZ
A young adult is admitted electively for a planned inpatient course of substance abuse rehabilitation after failing multiple outpatient attempts. As part of the scheduled multidisciplinary treatment, daily one-on-one behavioral psychotherapy sessions are conducted to teach coping strategies, contingency management, and behavioral modification techniques. The procedure documents delivery of individualized behavioral psychotherapy during the planned inpatient rehabilitation stay. Typical codes: HZ51ZZZ
An older adult with recurrent stimulant use disorder is readmitted for inpatient care following multiple relapses despite prior therapy; the current admission focuses on intensified behavioral interventions after previous treatments proved insufficient. Individual behavioral psychotherapy sessions are escalated in frequency and duration to address persistent maladaptive patterns and to revise the therapeutic approach as part of the readmission treatment plan. The procedure captures the provision of targeted behavioral individual psychotherapy during this repeat inpatient episode. Typical codes: HZ51ZZZ
