Benign neoplasm of ovary (D27)
The ICD-10 code D27 and its subcodes are specifically used to identify benign tumors of the ovary. These codes help categorize non-cancerous growths in either the right ovary (D27.0), left ovary (D27.1), or when the ovary affected is unspecified (D27.9).
These benign ovarian neoplasms include various types such as mature cystic teratomas, fibromas, serous cystadenomas, mucinous cystadenomas, and Brenner tumors. When medical coders encounter terms like "benign teratoma of ovary," "benign germ cell tumor," or "benign sex cord tumor," these commonly correspond to the D27 series codes. The unspecified category (D27.9) covers benign tumors of the ovary where the side is not detailed and may include rarer types like Microcystic stromal tumor or Meigs’ syndrome. Understanding these synonyms and corresponding codes is essential for accurate coding of benign ovarian growths using the ICD-10 system.

Instructional Notations
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.
