About Z83.718
Z83.718 is the ICD-10-CM diagnosis code for family history of other colon polyps. 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 Z83.71, choose Z83.718 (other colon polyps) only when documentation doesn't support a more specific option: adenomatous and serrated polyps (Z83.710), hyperplastic colon polyps (Z83.711) and colon polyps, unspecified (Z83.719).
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 FY2024, effective October 1, 2023, and changed in FY2026.
