Major neurocognitive disorder due to vascular disease, mild, NOS
Vascular dementia, mild, NOS

Excludes1 inherited from the categories above F01.A0

These are not written on F01.A0, but they bind it: a note on a category applies to every code beneath it. Billing F01.A0 with anything listed here is a denial.

Written on F01.A — Vascular dementia, mild

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

Other codes that can never be billed with F01.A0

These codes carry an Excludes1 note pointing at F01.A0. 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.A0 alone.

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

Risk adjustment

F01.A0 risk-adjusts. Under the CMS-HCC V28 model it maps to this category:

HCC 127 Dementia, Mild or Unspecified0.341 RAF

Coefficient shown for the Community Non-dual Aged segment. A higher HCC in the same hierarchy will suppress this one, so capturing it does not always add score.
