About Z92
Z92 is the ICD-10-CM diagnosis code for personal history of medical treatment. It belongs to 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 4 subcodes must be used instead.
To report this condition, pick the subcode that matches the documentation: Z92.0 (contraception), Z92.2 (therapy), Z92.3 (irradiation) and Z92.8 (treatment).
The conditions in its Excludes2 note aren't part of Z92, but may be coded alongside it if the patient has both: postprocedural states (Z98.-).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
