ICD-10 Code F20.8 – Other schizophrenia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F20.8 – Other schizophrenia
What it is
F20.8 identifies schizophrenia that does not fit the more specific ICD-10 subtypes. Use it when the record clearly supports schizophrenia, but the documented presentation is atypical or not otherwise classified.
Clinical signs
Clinical features vary; refer to documentation. Schizophrenia commonly involves delusions, hallucinations, disorganized thinking, and impaired functioning, but you should code only what is documented by the clinician.
When to use this code
Use F20.8 when the provider diagnoses schizophrenia and specifies “other” schizophrenia or documents a schizophrenia presentation that does not match a more specific code. It may also apply when the note describes schizophrenia without enough detail to select a more exact subtype, and documentation supports the diagnosis.
Do not use for
Do not use this code for schizoaffective disorder, brief psychotic disorder, or psychotic symptoms caused by substances or a medical condition. If the record supports a more specific schizophrenia subtype, code that instead.
Coding tip
Query the provider if the chart says schizophrenia but does not clarify the subtype.
