Non-billable headerICD-10-CM

Z86.0 is a non-billable header ICD-10-CM code for personal history of in-situ and benign neoplasms and neoplasms of uncertain behavior. 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 malignant neoplasms (Z85.-)

Other codes that can never be billed with Z86.0

These codes carry an Excludes1 note pointing at Z86.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Z86.0 alone.

  • Z87.41Personal history of dysplasia of the female genital tract

Risk adjustment

Z86.0 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 Z86.0

3 child codes. Green means billable.
