Z15.0 is a non-billable header ICD-10-CM code for genetic susceptibility to malignant neoplasm. It cannot be billed on its own: choose one of the more specific child codes below.

Code first

The underlying condition must be sequenced before this code.

  • , if applicable, any current malignant neoplasm (C00-C75, C81-C96)

Use additional code

Add a secondary code to capture the detail described below.

  • code, if applicable, for any personal history of malignant neoplasm (Z85.-)

Risk adjustment

Z15.0 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 Z15.0
