ICD-10-PCS Body System: ICD-10-PCS Body System GZ - None

The ICD-10-PCS root operation None (Character GZ) in the Mental Health classification encompasses non-surgical therapeutic and assessment services that do not involve physical alteration of the body. These procedures focus on psychological evaluation, treatment, and management.

Examples of this root operation include a wide range of mental health interventions. Psychological Tests (GZ1) involve administering standardized assessments to evaluate psychological function, while Crisis Intervention (GZ2) provides short-term stabilization for acutely distressed individuals. Medication Management (GZ3) monitors and adjusts psychiatric medications. Psychotherapeutic treatments like Individual Psychotherapy (GZ5), Family Psychotherapy (GZ7), and Group Psychotherapy (GZH) use behavioral or cognitive methods to improve mental well-being. Other examples are Electroconvulsive Therapy (GZB), Biofeedback (GZC), and Light Therapy (GZJ), each representing specialized treatment approaches. These codes accurately document non-invasive mental health procedures essential for clinical care and billing.
