ICD-10-PCS Code for Hypnosis: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group GZFZ includes procedures performed to induce a heightened state of suggestibility using auditory, visual, and tactile techniques. These ICD-10-PCS codes are used for inpatient documentation when a clinician provides therapeutic hypnosis to elicit an emotional or behavioral response as part of mental health care. Accurate coding within the ICD-10-PCS GZFZ group is essential for proper inpatient reimbursement, as it captures the procedure performed and supports clinical documentation accuracy.

GZFZZZZ	Hypnosis

Typical Clinical Scenarios

An adult inpatient with severe, treatment-resistant chronic pain admitted for multidisciplinary pain management including psychological therapies; the patient has significant pain-related anxiety and maladaptive behaviors that impede rehabilitation, so a clinician performs therapeutic hypnosis sessions to facilitate relaxation, reduce pain perception, and promote behavioral coping during the hospital stay. Typical codes: GZFZZZZ
A pediatric patient hospitalized after a traumatic injury who exhibits acute stress reactions and distress that interfere with medical care and wound management; a qualified clinician provides bedside hypnosis to decrease procedural anxiety, increase cooperation with dressing changes and reduce the need for sedative medications during the admission. Typical codes: GZFZZZZ
An inpatient receiving psychiatric care for severe phobia-related functional impairment who has not responded to first-line therapies; as part of an escalated, coordinated mental health treatment plan during the admission, a clinician conducts hypnotic induction sessions to target maladaptive emotional responses and facilitate behavioral change. Typical codes: GZFZZZZ
