F07.89 ICD-10-CM Code: Other personality and behavioral disorders due to known physiological condition

F07.89 is the ICD-10-CM diagnosis code for other personality and behavioral disorders due to known physiological condition. This code describes personality and behavioral changes that result from a medical condition affecting the brain or body, when the specific cause doesn't fit other defined categories. These changes are directly caused by the underlying medical condition rather than being primary mental health disorders. F07.89 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).

F07.89 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 or behavioral changes, as this code requires a known medical cause to be identified and coded separately.
