ICD-10 Code F48.8 – Other specified nonpsychotic mental disorders (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F48.8 – Other specified nonpsychotic mental disorders
What it is
F48.8 is used for nonpsychotic mental disorders that do not fit a more specific ICD-10 category. It captures conditions with documented mental or behavioral symptoms, but without psychosis.
Clinical signs
Clinical features vary; refer to documentation. You may see distress, impaired functioning, anxiety-like symptoms, or other nonpsychotic complaints that do not meet criteria for a named disorder.
When to use this code
Use this code when the provider documents a specific nonpsychotic mental disorder that is not classified elsewhere in ICD-10. It is appropriate when the record supports a mental health condition but lacks a better-defined code. Check documentation for the exact diagnosis and whether a more specific code applies.
Do not use for
Do not use F48.8 for psychotic disorders, mood disorders, or anxiety disorders that have their own ICD-10 codes. Avoid using it when the chart supports a more specific diagnosis.
Coding tip
Code F48.8 only after confirming there is no more specific documented diagnosis available.
