Z86.0Personal history of in-situ and benign neoplasms and neoplasms of uncertain behavior

Z86.0 is the ICD-10-CM diagnosis code for personal history of in-situ and benign neoplasms and neoplasms of uncertain behavior. It belongs to category Z86 (personal history of certain other diseases), 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 3 subcodes must be used instead.

Within Z86 (personal history of certain other diseases), Z86.0 is specifically for personal history of in-situ and benign neoplasms and neoplasms of uncertain behavior. Related codes cover infectious and parasitic diseases (Z86.1), diseases of the blood and blood-forming organs and certain disorders involving the immune mechanism (Z86.2), endocrine, nutritional and metabolic diseases (Z86.3), mental and behavioral disorders (Z86.5), diseases of the nervous system and sense organs (Z86.6) and diseases of the circulatory system (Z86.7).

To report this condition, pick the subcode that matches the documentation: Z86.00 (neoplasm), Z86.01 (neoplasm) and Z86.03 (behavior).

The conditions in its Excludes2 note aren't part of Z86.0, but may be coded alongside it if the patient has both: personal history of malignant neoplasms (Z85.-).

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.
