F01.A

F01.A — Vascular dementia, mild

Non-billable headerICD-10-CM

F01.A is a non-billable header ICD-10-CM code for vascular dementia, mild. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

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

Other codes that can never be billed with F01.A

These codes carry an Excludes1 note pointing at F01.A. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading F01.A alone.

F06.7Mild neurocognitive disorder due to known physiological condition
G31.84Mild cognitive impairment of uncertain or unknown etiology

Risk adjustment

F01.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 history

F01.A has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.

Code to one of these instead F01.A
