Notes
General instructions on how these codes are used.
- Z codes represent reasons for encounters. A corresponding procedure code must accompany a Z code if a procedure is performed. Categories Z00-Z99 are provided for occasions when circumstances other than a disease, injury or external cause classifiable to categories A00-Y89 are recorded as 'diagnoses' or 'problems'. This can arise in two main ways:
- (a) When a person who may or may not be sick encounters the health services for some specific purpose, such as to receive limited care or service for a current condition, to donate an organ or tissue, to receive prophylactic vaccination (immunization), or to discuss a problem which is in itself not a disease or injury.
- (b) When some circumstance or problem is present which influences the person's health status but is not in itself a current illness or injury.

Cancer
Cancer is not just one disease but many diseases. Cancer begins in your cells, which are the building blocks of your body. Usually, your body forms new cells as needed, replacing old cells that die. Sometimes this process goes wrong. New cells grow even when you don't need them, and old cells don't die when they should.

Questions About Z80.2Overview
Is Z80.2 (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 other respiratory and intrathoracic organs on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does Z80.2 group to?
On inpatient claims, family history of malignant neoplasm of other respiratory and intrathoracic organs maps to MS-DRG 951 (other Factors Influencing Health Status), which carries a relative weight of 0.5574. Higher weights mean higher Medicare reimbursement.
Can Z80.2 be a principal diagnosis?
No. The Medicare Code Editor rejects this code as a principal diagnosis because family history of malignant neoplasm of other respiratory and intrathoracic organs describes a circumstance that influences health status rather than a current illness. Report it as a secondary diagnosis.
Is Z80.2 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 other respiratory and intrathoracic organs on inpatient claims. The code appears in the Persons with potential health hazards related to family and personal history and certain conditions influencing health status (Z77-Z99) range of the CMS exempt list.
What is the ICD-9 equivalent of Z80.2?
Under the General Equivalence Mappings, family history of malignant neoplasm of other respiratory and intrathoracic organs converts to ICD-9-CM V16.2 (fam hx-intrathoracic mal). The mapping is a direct match.
