N80.0Endometriosis of uterus

Non-billable headerICD-10-CM

N80.0 is a non-billable header ICD-10-CM code for endometriosis of uterus. It cannot be billed on its own: choose one of the more specific child codes below.

  • stromal endometriosis (D39.0)

Inclusion terms

Alternative wordings a physician may use in the chart for this same code.

  • Endometriosis of the cervix

N80.0 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 N80.0
