About coding Hyperovarism
The ICD-10-CM code for Hyperovarism is E28.8 (Other ovarian dysfunction).
Within E28, choose E28.8 (Other ovarian dysfunction) only when documentation doesn't support a more specific option: estrogen excess (E28.0), androgen excess (E28.1), polycystic ovarian syndrome (E28.2), primary ovarian failure (E28.3) and unspecified (E28.9).
Don't report E28.8 together with the conditions in its Excludes1 note: postprocedural ovarian failure (E89.4-).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
Don't confuse with (Excludes1 for E28.8)
- postprocedural ovarian failure (E89.4-)
