Questions About Z80.44Overview

Is Z80.44 (Family history of malignant neoplasm of genital organs) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report family history of malignant neoplasm of fallopian tube(s) on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

Can Z80.44 be a principal diagnosis?

No. The Medicare Code Editor rejects this code as a principal diagnosis because family history of malignant neoplasm of fallopian tube(s) describes a circumstance that influences health status rather than a current illness. Report it as a secondary diagnosis.

Is Z80.44 exempt from POA reporting?

Yes. CMS lists this code among those exempt from present on admission reporting, so hospitals do not assign a POA indicator for family history of malignant neoplasm of fallopian tube(s) on inpatient claims.
