F02: Dementia in other diseases classified elsewhere
Non-billable headerICD-10-CM
F02 is a non-billable header ICD-10-CM code for dementia in other diseases classified elsewhere. 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.

Excludes2: not included here, but may coexist
The excluded condition is not part of this code, but a patient can have both. You may code both.
