About coding tumor benign brenner
The ICD-10-CM code for tumor benign brenner is D27.9 (Benign neoplasm of unspecified ovary). The official index lists 3 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on D27.9.
Within D27, choose D27.9 (unspecified ovary) only when documentation doesn't support a more specific option: right ovary (D27.0) and left ovary (D27.1).
Use an additional code to identify any functional activity.
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
