ICD-10-PCS Code For Interpersonal: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group GZ53 includes procedures performed to provide individual psychotherapy focused on interpersonal functioning. These ICD-10-PCS codes are used for inpatient documentation when a patient receives one-on-one psychotherapy addressing interpersonal relationships, communication, and social functioning as part of their treatment plan.

Interpersonal Individual Psychotherapy Procedure Overview

Procedures in this group involve individual psychotherapy focused on interpersonal themes and skills to improve a patient’s mental health and functioning. These procedures are part of mental health treatment rather than targeting any anatomical body system, and they involve therapeutic techniques delivered one-on-one. Accurate coding matters for inpatient reimbursement because it documents the type of psychotherapy provided and supports appropriate case mix and payment.
