Billable / specific codeICD-10-CMright

N83.201 is a billable, specific ICD-10-CM code for unspecified ovarian cyst, right side. It is valid for submission on a claim.

Excludes1 inherited from the categories above N83.201

These are not written on N83.201, but they bind it: a note on a category applies to every code beneath it. Billing N83.201 with anything listed here is a denial.

Written on N83.2 Other and unspecified ovarian cysts

  • developmental ovarian cyst (Q50.1)
  • neoplastic ovarian cyst (D27.-)
  • polycystic ovarian syndrome (E28.2)
  • Stein-Leventhal syndrome (E28.2)

Excludes2 inherited from the categories above N83.201

Also inherited, and the opposite of Excludes1: these conditions are not part of N83.201, but a patient can have both, so you may code both.

Risk adjustment

N83.201 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

N83.201 is named in 2 Medicare coverage policies 2 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
