N80.A — Endometriosis of bladder and ureters
N80.A is a non-billable header ICD-10-CM code for endometriosis of bladder and ureters. It cannot be billed on its own: choose one of the more specific child codes below.
Other codes that can never be billed with N80.A
These codes carry an Excludes1 note pointing at N80.A. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading N80.A alone.
- N85Other noninflammatory disorders of uterus, except cervix
Risk adjustment
N80.A 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 history
N80.A has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
