N85.0 — Endometrial hyperplasia
N85.0 is a non-billable header ICD-10-CM code for endometrial hyperplasia. It cannot be billed on its own: choose one of the more specific child codes below.
Excludes1 inherited from the categories above N85.0
These are not written on N85.0, but they bind it: a note on a category applies to every code beneath it. Billing N85.0 with anything listed here is a denial.
Other codes that can never be billed with N85.0
These codes carry an Excludes1 note pointing at N85.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading N85.0 alone.
Risk adjustment
N85.0 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 history
N85.0 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
