About coding stimulation
The ICD-10-CM code for stimulation is E28.1 (Androgen excess).
Within E28 (ovarian dysfunction), E28.1 is specifically for androgen excess. Related codes cover estrogen excess (E28.0), polycystic ovarian syndrome (E28.2), primary ovarian failure (E28.3), other ovarian dysfunction (E28.8) and unspecified (E28.9).
Use an additional code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
