About Z87.890

Z87.890 is the ICD-10-CM diagnosis code for personal history of sex reassignment. 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 a header code, so it can't be reported by itself; one of its 5 subcodes must be used instead.

Within Z87.89 (personal history of other specified conditions), Z87.890 is specifically for personal history of sex reassignment. Related codes cover nicotine dependence (Z87.891), anaphylaxis (Z87.892), gender detransition (Z87.893) and other specified conditions (Z87.898).

To report this condition, pick the subcode that matches the documentation: Z87.8901 (transition), Z87.8902 (transition), Z87.8903 (transition), Z87.8904 (surgery) and Z87.8909 (transition).

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

It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2027 (expanded into subcodes).

Before ICD-10, this condition was coded in ICD-9-CM as 302.50 (Trans-sexualism with unspecified sexual history).
