Z86.0101Personal history of adenomatous and serrated colon polyps

Z86.0101 is the ICD-10-CM diagnosis code for personal history of adenomatous and serrated colon polyps. It belongs to category Z86 (personal history of certain other diseases), 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 Z86.010 (personal history of colon polyps), Z86.0101 is specifically for personal history of adenomatous and serrated colon polyps. Related codes cover unspecified (Z86.0100), hyperplastic colon polyps (Z86.0102) and other colon polyps (Z86.0109).

Code first: any follow-up examination after treatment (Z09).

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.
