ICD-10 Code F24 – Shared psychotic disorder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F24 – Shared psychotic disorder
What it is
F24 identifies shared psychotic disorder, a condition in which a delusional belief is transmitted from one person to another in a close relationship. Use it when documentation shows the shared nature of the delusion.
Clinical signs
Clinical features vary; refer to documentation. Typical references describe persistent delusional beliefs in two or more closely connected people, often with one primary individual and one or more secondary individuals adopting the same belief.
When to use this code
Use F24 when the record clearly states shared psychotic disorder or an induced delusional disorder between closely associated persons. It may also apply when a clinician documents shared delusions without another more specific psychotic diagnosis. Check documentation if the relationship or diagnosis is unclear.
Do not use for
Do not use this code for isolated delusions, schizophrenia, or other psychotic disorders that are not described as shared. If the chart does not document a shared delusional relationship, check documentation.
Coding tip
Assign F24 only when the provider explicitly links the delusion to another person’s influence or shared belief.
