Is F03.A a billable ICD-10-CM code?

No. F03.A is a non-billable header code. Code to a higher level of specificity using one of its child codes.

Where does F03.A sit in the tabular list?

Mental, Behavioral and Neurodevelopmental disorders (F01-F99), in the block Mental disorders due to known physiological conditions (F01-F09).

What cannot be coded together with F03.A?

F03.A carries Excludes1 notes, which means the conditions they list can never be coded together with it on the same encounter.

F03.A

F03.A — Unspecified dementia, mild

Non-billable headerICD-10-CM

F03.A is a non-billable header ICD-10-CM code for unspecified 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-)

Excludes2 inherited from the categories above F03.A

Also inherited, and the opposite of Excludes1: these conditions are not part of F03.A, but a patient can have both, so you may code both.

Written on F03 — Unspecified dementia

dementia with delirium or acute confusional state (F05)
mild memory disturbance due to known physiological condition (F06.8)

Other codes that can never be billed with F03.A

These codes carry an Excludes1 note pointing at F03.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 F03.A alone.

F06Other mental disorders due to known physiological condition
F06.7Mild neurocognitive disorder due to known physiological condition
G30Alzheimer's disease
G31.84Mild cognitive impairment of uncertain or unknown etiology
R54Age-related physical debility

Risk adjustment

F03.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

F03.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 F03.A

5 child codes. Green means billable.
