About Z87.8902

Z87.8902 is the ICD-10-CM diagnosis code for personal history of medical gender transition. It belongs to category Z87 (personal history of other diseases and conditions), 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 Z87.890 (personal history of sex reassignment), Z87.8902 is specifically for personal history of medical gender transition. Related codes cover social gender transition (Z87.8901), surgical gender transition (Z87.8903), intersex surgery (Z87.8904) and unspecified gender transition (Z87.8909).

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 887 (Other Mental Disorder Diagnoses, relative weight 1.1139), in MDC 19 (Mental Diseases and Disorders), 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 FY2027, effective October 1, 2026.
