Inclusion terms

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

Ovarian cyst, NOS

Excludes1 inherited from the categories above N83.209

These are not written on N83.209, but they bind it: a note on a category applies to every code beneath it. Billing N83.209 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 N83.209

Also inherited, and the opposite of Excludes1: these conditions are not part of N83.209, but a patient can have both, so you may code both.

Written on N83 — Noninflammatory disorders of ovary, fallopian tube and broad ligament

hydrosalpinx (N70.1-)

Risk adjustment

N83.209 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

N83.209 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
