N85.7Hematometra

Billable / specific codeICD-10-CM

N85.7 is a billable, specific ICD-10-CM code for hematometra. 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.

  • hematometra with hematocolpos (N89.7)

Inclusion terms

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

  • Hematosalpinx with hematometra

Excludes1 inherited from the categories above N85.7

These are not written on N85.7, but they bind it: a note on a category applies to every code beneath it. Billing N85.7 with anything listed here is a denial.

Written on N85 Other noninflammatory disorders of uterus, except cervix

  • endometriosis (N80.-)
  • inflammatory diseases of uterus (N71.-)
  • noninflammatory disorders of cervix, except malposition (N86-N88)
  • polyp of corpus uteri (N84.0)
  • uterine prolapse (N81.-)

Other codes that can never be billed with N85.7

These codes carry an Excludes1 note pointing at N85.7. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading N85.7 alone.

Risk adjustment

N85.7 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

N85.7 is named in 1 Medicare coverage policy 1 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.

How N85.7 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 N85.7.

  • Hematometra
  • Hemorrhage, hemorrhagicintrauterine
  • Hematosalpinxwithhematometra
  • Hemosalpinxwithhematometra

Code history
