Z80.44Family history of malignant neoplasm of fallopian tube(s)

Z80.44 is the ICD-10-CM diagnosis code for family history of malignant neoplasm of fallopian tube(s). It belongs to category Z80 (family history of primary malignant neoplasm), block Z77-Z99 (persons with potential health hazards related to family and personal history and certain conditions influencing health status) and chapter 21 (factors influencing health status and contact with health services). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within Z80.4 (family history of malignant neoplasm of genital organs), Z80.44 is specifically for family history of malignant neoplasm of fallopian tube(s). Related codes cover ovary (Z80.41), prostate (Z80.42), testis (Z80.43) and other genital organs (Z80.49).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 951 (Other Factors Influencing Health Status, relative weight 0.5577), in MDC 23 (Factors Influencing Health Status and Other Contacts with Health Services), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It is not acceptable as the principal diagnosis for an inpatient stay; it may be reported as a secondary diagnosis.

It is exempt from present-on-admission (POA) reporting, so no POA indicator is required.

It was added in FY2026, effective October 1, 2025.
