About N83.20
N83.20 is the ICD-10-CM diagnosis code for unspecified ovarian cysts. It belongs to category N83 (noninflammatory disorders of ovary, fallopian tube and broad ligament), block N80-N98 (noninflammatory disorders of female genital tract) and chapter 14 (diseases of the genitourinary system). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.
Within N83.2, choose N83.20 (Unspecified ovarian cysts) only when documentation doesn't support a more specific option: other ovarian cysts (N83.29).
To report this condition, pick the subcode that matches the documentation: N83.201 (side), N83.202 (side) and N83.209 (side).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2017 (expanded into subcodes).
