1 – Compounded treatments
Medicare supplements cover most broad categories of medication-the key is to find one that works for you.
The reason for this is that compounded medications are not usually approved by the FDA and therefore are not covered by Medicare Part D.

2 – Sexual dysfunction medications
Medications for erectile dysfunction and sexual dysfunction are also not covered by Medicare, since they are not considered medically necessary.

3 Cosmetic drugs
By Priority Health, cosmetic drugs will also never be covered by Medicare. Nonetheless, some drugs used to treat skin conditions may also have cosmetic benefits, so it’s worth asking.

4 Fertility medication
In spite of the fact that Medicare is primarily intended for retirees, some individuals on disability may be eligible for Medicare benefits before they reach retirement age. Unless a doctor deems it medically necessary, these people are unlikely to be eligible for fertility assistance, according to a Kaiser Family Foundation (KFF) report.
