What This Code Means
F07.0 is the ICD-10-CM diagnosis code for personality change due to known physiological condition. A change in personality or behavior caused by a known medical condition affecting the brain, such as a stroke, tumor, or head injury. F07.0 sits in the ICD-10-CM chapter for mental, behavioral and neurodevelopmental disorders (f01-f99), within the section covering mental disorders due to known physiological conditions (f01-f09).
F07.0 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.
Always document the underlying physiological condition causing the personality change.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for F07.0 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.

- •Always document the underlying physiological condition causing the personality change
- •This code requires evidence that the personality change is directly attributable to a medical condition, not a primary psychiatric disorder
