Do any Medicare Part D plans cover extended or bonus drugs beyond the normal Medicare Part D formulary?

Yes. Some Medicare Part D prescription drug plans cover, not only brand-name and generic prescription drugs, but also so-called "Bonus Drugs" not usually covered by the Medicare Part D program, such as:

B Complex w/Vitamin C
Cyanocobalamin
Folic Acid
Levitra
Mephyton
Multiple Vitamin Injection
Viagra (or other ED medications)
Over-the-Counter (OTC) medications

What you pay for your Supplemental Drugs...

Please note that when you purchase one of your Medicare Part D plan's Supplemental (non-Part D) drugs, payment for these "Bonus" or "Supplemental" Drugs – made by you or your Medicare drug plan – may be treated differently as compared to other Medicare Part D drug payments.

For example, "Bonus Drug" purchases may not count toward your annual Total out-of-pocket (TrOOP) threshold or (RxMOOP) - which is set at $2,000 in 2025 ($2,100 in 2026). After reaching RxMOOP, Medicare Part D beneficiaries will enter Catastrophic Coverage and have a $0 copay (no additional costs) for all formulary Medicare Part D drugs through the remainder of the year.

Please note: The medications below were formerly Bonus Drugs but are now included on many Medicare Part D plan formularies.

Please also note that we do not include non-Part D "Bonus Drugs" or "Supplemental Drugs" in our Formulary Browser or the drug finder Drug Finder tools since they do not affect your Medicare Part D plan's total out-of-pocket spending (TrOOP) limit.
