Clinical context
Inherited from F68 (Other disorders of adult personality and behavior)
ICD-10-CM code F68 covers other disorders of adult personality and behavior within the F60-F69 range (disorders of adult personality and behavior). Use the most specific leaf code that matches the documented clinical presentation — the parent code is a navigational header, not a billable code on its own. Documentation should capture symptom onset, course, severity, and functional impact. Where applicable, attach a validated screening instrument score (PHQ-9, GAD-7, PCL-5, or equivalent) and note any comorbid conditions in the same encounter.

- Non-billable/Non-specific code
Coding rules
- Specify the leaf code — the parent code (e.g. F32) is a navigational header; billing requires a leaf code (F32.0, F32.1, etc.) that matches the documented presentation.
- Document onset, course, and severity (mild / moderate / severe) plus functional impact. Payers use this combination when adjudicating medical necessity.
- Attach a validated instrument score (PHQ-9, GAD-7, PCL-5, or equivalent) at intake and at follow-up where applicable. Objective measures support code selection and continued authorization.
- Review at every visit and update if presentation changes — including remission and partial remission states.
