Z85Personal history of malignant neoplasm

Z85 is the ICD-10-CM diagnosis code for personal history of malignant neoplasm. 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 10 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: Z85.0 (of digestive organs), Z85.1 (of trachea, bronchus and lung), Z85.2 (of other respiratory and intrathoracic organs), Z85.3 (of breast), Z85.4 (of genital organs), Z85.5 (of urinary tract), Z85.6 (leukemia), Z85.7 (tissues) and 2 more.

The conditions in its Excludes2 note aren't part of Z85, but may be coded alongside it if the patient has both: personal history of benign neoplasm (Z86.01-) and personal history of carcinoma-in-situ (Z86.00-).

Code first: any follow-up examination after treatment of malignant neoplasm (Z08).

Use an additional code to identify: alcohol use and dependence (F10.-), exposure to environmental tobacco smoke (Z77.22), history of tobacco dependence (Z87.891), occupational exposure to environmental tobacco smoke (Z57.31), tobacco dependence (F17.-) and 1 more.

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