Benign neoplasm of ovary (D27) ICD-10-CM
The D27 code range covers benign neoplasm of ovary with 4 ICD-10-CM diagnosis codes. 3 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.
Use Additional Code
The “use additional code” indicates that a secondary code could be used to further specify the patient’s condition. This note is not mandatory and is only used if enough information is available to assign an additional code.
- code to identify any functional activity.
Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the D27 range.
Luteoma
An ovarian neoplasm composed of LUTEAL CELLS derived from luteinized GRANULOSA CELLS and THECA CELLS. Luteomas respond to GONADOTROPINS, and vary in their hormone production (PROGESTERONE; ESTROGENS; or ANDROGENS). During PREGNANCY, a transient type of luteoma may develop due to an exaggerated LUTEINIZATION of the OVARY.
Thecoma
A gonadal stromal neoplasm composed only of THECA CELLS, occurring mostly in the postmenopausal OVARY. It is filled with lipid-containing spindle cells and produces ESTROGENS that can lead to ENDOMETRIAL HYPERPLASIA; UTERINE HEMORRHAGE; or other malignancies in postmenopausal women and sexual precocity in girls. When tumors containing theca cells also contain FIBROBLASTS, they are identified as thecoma-fibroma tumors with less active hormone production.
