About Z83.72

Z83.72 is the ICD-10-CM diagnosis code for family history of familial adenomatous polyposis. It belongs to category Z83 (family history of other specific disorders), 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 Z83.7 (family history of diseases of the digestive system), Z83.72 is specifically for family history of familial adenomatous polyposis. Related codes cover colonic polyps (Z83.71) and other diseases of the digestive system (Z83.79).

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 FY2025, effective October 1, 2024.
