Is F02.81 a billable ICD-10-CM code?

No. F02.81 is a non-billable header code. Code to a higher level of specificity using one of its child codes.

Where does F02.81 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 F02.81?

F02.81 carries Excludes1 notes, which means the conditions they list can never be coded together with it on the same encounter. Some are written on the categories above F02.81 (F02) and apply to it just the same.

F02.81

F02.81 — Dementia in other diseases classified elsewhere, unspecified severity, with behavioral disturbance

Non-billable headerICD-10-CM

F02.81 is a non-billable header ICD-10-CM code for dementia in other diseases classified elsewhere, unspecified severity, with behavioral disturbance. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 inherited from the categories above F02.81

These are not written on F02.81, but they bind it: a note on a category applies to every code beneath it. Billing F02.81 with anything listed here is a denial.

Written on F02 — Dementia in other diseases classified elsewhere

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

Excludes2 inherited from the categories above F02.81

Also inherited, and the opposite of Excludes1: these conditions are not part of F02.81, but a patient can have both, so you may code both.

Written on F02 — Dementia in other diseases classified elsewhere

dementia in alcohol and psychoactive substance disorders (F10-F19, with .17, .27, .97)
vascular dementia (F01.5-, F01.A-, F01.B-, F01.C-)

Other codes that can never be billed with F02.81

These codes carry an Excludes1 note pointing at F02.81. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading F02.81 alone.

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

Risk adjustment

F02.81 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.

Medicare coverage

F02.81 is named in 1 Medicare coverage policy — 1 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
