F02.ADementia in other diseases classified elsewhere, mild

Non-billable headerICD-10-CM

F02.A is a non-billable header ICD-10-CM code for dementia in other diseases classified elsewhere, mild. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

  • mild neurocognitive disorder due to known physiological condition with or without behavioral disturbance (F06.7-)

Risk adjustment

F02.A does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Code to one of these instead F02.A

5 child codes. Green means billable.
