N83.2 vs Q50.1
N83.2 (Other and unspecified ovarian cysts) compared with Q50.1 (Developmental ovarian cyst), from the official CMS tabular data. Do not report these codes together: the official tabular list marks them Excludes1.
Can these codes be reported together?
No — do not report together. N83.2 carries an Excludes1 note covering Q50.1: “developmental ovarian cyst (Q50.1)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
