Where does Z85 sit in the tabular list?

Factors influencing health status and contact with health services (Z00-Z99), in the block Persons with potential health hazards related to family and personal history and certain conditions influencing health status (Z77-Z99).

Z85

Z85 — Personal history of malignant neoplasm

Non-billable headerICD-10-CM

Z85 is a non-billable header ICD-10-CM code for personal history of malignant neoplasm. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes2 — not included here, but may coexist

The excluded condition is not part of this code, but a patient can have both. You may code both.

personal history of benign neoplasm (Z86.01-)
personal history of carcinoma-in-situ (Z86.00-)

Code first

The underlying condition must be sequenced before this code.

any follow-up examination after treatment of malignant neoplasm (Z08)

Use additional code

Add a secondary code to capture the detail described below.

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.-)
tobacco use (Z72.0)

Other codes that can never be billed with Z85

These codes carry an Excludes1 note pointing at Z85. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Z85 alone.

Z85.52Personal history of malignant neoplasm of kidney
C81Hodgkin lymphoma
C82Follicular lymphoma
C83Non-follicular lymphoma
C84Mature T/NK-cell lymphomas
C85Other specified and unspecified types of non-Hodgkin lymphoma
Z87.430Personal history of prostatic dysplasia
Z87.44Personal history of diseases of urinary system

Risk adjustment

Z85 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Code to one of these instead Z85

10 child codes. Green means billable.
