ICD-10 Code F25.9 – Schizoaffective disorder, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F25.9 – Schizoaffective disorder, unspecified
What it is
F25.9 identifies schizoaffective disorder when the record does not specify the bipolar type or depressive type. Use it for a mixed psychotic and mood disorder that is documented, but not further classified.
Clinical signs
Clinical features vary; refer to documentation. Typical records describe psychotic symptoms such as delusions or hallucinations along with mood episodes, but the subtype is not identified.
When to use this code
Use this code when the clinician documents schizoaffective disorder without stating whether it is bipolar type or depressive type. It is also appropriate when the available note confirms the diagnosis but lacks enough detail for a more specific code.
If later documentation identifies the subtype, update coding to the more specific schizoaffective diagnosis. Check documentation for any associated mood features or psychotic symptoms that support the diagnosis.
Do not use for
Do not use F25.9 for schizophrenia, bipolar disorder, or major depressive disorder without psychotic features. Do not assign it when the record clearly identifies a specific schizoaffective subtype.
Coding tip
Code the documented diagnosis exactly as stated, and query the provider if the schizoaffective subtype is missing but clinically relevant.
