E78.5: Hyperlipidemia, unspecified
E29.1: Testicular hypofunction
I see no reason why this would be denied for "mutually exclusive." They're two different body systems, one is not a symptom associated with the other, and there's no excludes1 note. Scratching my head over this.
Unless there's a wrong gender marker somewhere, since E29.1 couldn't be used on a coded-female patient.
