Z92.2Personal history of drug therapy

Z92.2 is the ICD-10-CM diagnosis code for personal history of drug therapy. It belongs to category Z92 (personal history of medical treatment), 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 7 subcodes must be used instead.

Within Z92 (personal history of medical treatment), Z92.2 is specifically for personal history of drug therapy. Related codes cover contraception (Z92.0), irradiation (Z92.3) and other medical treatment (Z92.8).

To report this condition, pick the subcode that matches the documentation: Z92.21 (chemotherapy), Z92.22 (therapy), Z92.23 (therapy), Z92.24 (therapy), Z92.25 (therapy), Z92.26 (therapy) and Z92.29 (therapy).

The conditions in its Excludes2 note aren't part of Z92.2, but may be coded alongside it if the patient has both: long term (current) drug therapy (Z79.-).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
