What This Code Means

F06.70 is the ICD-10-CM diagnosis code for mild neurocognitive disorder due to known physiological condition without behavioral disturbance. Mild problems with memory, thinking, or concentration due to a known medical condition, without behavioral problems. F06.70 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).

F06.70 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.

This code is for mild cognitive impairment only; use other codes for moderate or severe neurocognitive disorders.

HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for F06.70 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
