ICD-10-CM F24: Shared Psychotic Disorder Overview

The International Classification of Diseases, 10th Revision, Clinical Modification (ICD-10-CM) code group F24 covers shared delusional disorder where a delusional belief is transmitted from one individual to another, targeting psychiatric and behavioral health. These diagnoses involve primary and secondary cases of induced delusional beliefs and affect mental and social functioning. Accurate coding ensures complete clinical documentation and supports appropriate reimbursement for psychiatric services.

When to Use

Use a code from this group when clinical documentation indicates a delusional belief adopted by one person as a result of a close relationship with another individual who has a psychotic disorder. Select codes that reflect the role of each individual and any specified clinical detail recorded in the medical record.

Typical Clinical Scenarios

A middle-aged woman brings her elderly mother to outpatient psychiatry because the mother has developed persistent false beliefs that neighbors are poisoning the family food; the daughter shares and reinforces many of these delusional ideas and the mother’s symptoms began after moving in with the daughter. Evaluation reveals that the second person’s delusions closely mirror the primary patient’s firm false beliefs rather than independent psychosis, leading to assignment of a shared psychotic disorder diagnosis. Typical codes: F24
An adult man presents to the emergency department with agitation and paranoid delusions after living in close quarters with a roommate who has a longstanding persecutory delusion; the patient’s symptoms emerged only after prolonged exposure and remit when separated from the roommate. Because the patient’s psychotic symptoms appear induced by and closely resemble another person’s delusions, a shared psychotic disorder code is applied in the acute setting. Typical codes: F24
A caregiver brings an adolescent to a community mental health clinic because the teen has adopted stalking-related delusional beliefs from an older sibling who has chronic delusional disorder; the adolescent’s social and school functioning have declined over months but symptoms improve with reduced contact. The clinic documents the secondary nature of the adolescent’s delusions due to influence from a dominant family member, and codes the condition as a shared psychotic disorder for ongoing treatment planning. Typical codes: F24
