N83.20 — Unspecified ovarian cysts

Non-billable headerICD-10-CM

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 N83.20

Also inherited, and the opposite of Excludes1: these conditions are not part of N83.20, but a patient can have both, so you may code both.

Risk adjustment

N83.20 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

N83.20 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
