Ever heard of a health plan denying coverage for a certain diagnosis to a certain age group? Civil rights?

You can keep appealing their decision. Get your doctor to state the acne is a symptom of the polycystic ovaries and not just plain acne. While I agree their policy is wrong, it is in your policy which when you subscribed you agreed to abide by it. Just keep fighting for the coverage. Our insurance co. originally refused to pay for my husband to have his teeth cut out because it was cosmetic. We fought it by having his dentist and doctors submit proof it was for health reasons. We won the appeal and they paid.
