About D27
D27 is the ICD-10-CM diagnosis code for benign neoplasm of ovary. It belongs to block D10-D36 (benign neoplasms, except benign neuroendocrine tumors) and chapter 2 (neoplasms). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.
To report this condition, pick the subcode that matches the documentation: D27.0 (ovary), D27.1 (ovary) and D27.9 (ovary).
The conditions in its Excludes2 note aren't part of D27, but may be coded alongside it if the patient has both: corpus albicans cyst (N83.2-), corpus luteum cyst (N83.1-), endometrial cyst (N80.1-), follicular (atretic) cyst (N83.0-) and 3 more.
Use an additional code to identify any functional activity.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
