Questions About Z80.1Overview
Is Z80.1 (Family history of primary malignant neoplasm) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report family history of malignant neoplasm of trachea, bronchus and lung on HIPAA-covered claims from October 1, 2025 through September 30, 2026.
Can Z80.1 be a principal diagnosis?
No. The Medicare Code Editor rejects this code as a principal diagnosis because family history of malignant neoplasm of trachea, bronchus and lung describes a circumstance that influences health status rather than a current illness. Report it as a secondary diagnosis.
Is Z80.1 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 trachea, bronchus and lung on inpatient claims.
What is the ICD-9 equivalent of Z80.1?
Under the General Equivalence Mappings, family history of malignant neoplasm of trachea, bronchus and lung converts to ICD-9-CM V16.1 (fm hx-trach/bronchog mal). The mapping is a direct match.
