About Z86
Z86 is the ICD-10-CM diagnosis code for personal history of certain other diseases. 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 7 subcodes must be used instead.
To report this condition, pick the subcode that matches the documentation: Z86.0 (behavior), Z86.1 (diseases), Z86.2 (mechanism), Z86.3 (diseases), Z86.5 (disorders), Z86.6 (organs) and Z86.7 (system).
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 hasn't changed since.
