N84.0 — Polyp of corpus uteri
N84.0 is a billable, specific ICD-10-CM code for polyp of corpus uteri. It is valid for submission on a claim.
Excludes1 — never code together
These conditions cannot occur together. Billing both on the same encounter is a denial.
- polypoid endometrial hyperplasia (N85.0-)
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Polyp of endometrium
- Polyp of uterus NOS
Other codes that can never be billed with N84.0
These codes carry an Excludes1 note pointing at N84.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading N84.0 alone.
- N85Other noninflammatory disorders of uterus, except cervix
Risk adjustment
N84.0 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.
Medicare coverage
N84.0 is named in 5 Medicare coverage policies — 5 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.

How N84.0 is indexed
Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to N84.0.
- Polyp, polypus›corpus uteri
- Polyp, polypus›endometrium
- Polyp, polypus›myometrium
