About N83.1
N83.1 is the ICD-10-CM diagnosis code for corpus luteum cyst. 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 (noninflammatory disorders of ovary, fallopian tube and broad ligament), N83.1 is specifically for corpus luteum cyst. Related codes cover follicular cyst of ovary (N83.0), other and unspecified ovarian cysts (N83.2), acquired atrophy of ovary and fallopian tube (N83.3), prolapse and hernia of ovary and fallopian tube (N83.4), torsion of ovary, ovarian pedicle and fallopian tube (N83.5), Hematosalpinx (N83.6), hematoma of broad ligament (N83.7), other noninflammatory disorders of ovary, fallopian tube and broad ligament (N83.8) and 1 more.
To report this condition, pick the subcode that matches the documentation: N83.10 (of ovary, unspecified side), N83.11 (of right ovary) and N83.12 (of left ovary).
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).
