Questions About F02.A11Overview

Is F02.A11 a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report dementia in other diseases classified elsewhere, mild, with agitation on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

Can F02.A11 be a principal diagnosis?

No. This is a manifestation code: dementia in other diseases classified elsewhere, mild, with agitation describes the manifestation of an underlying disease rather than the disease itself, so the underlying condition is sequenced first.
