The list of drugs your Medicare Part D or Medicare Advantage plan covers, organized into pricing tiers.
Tiers group covered drugs by cost — Tier 1–2 are low-cost generics, Tier 3 preferred brands, Tier 4 non-preferred, Tier 5 specialty drugs.
Your plan must approve the drug before covering it, usually to confirm it's medically necessary.
You may need to try one or more lower-cost drugs first before the plan covers a more expensive option.
Plans may limit how much of a drug they cover over a period of time for safety or cost reasons.
You can request a formulary exception and appeal, switch to a covered alternative, or compare plans during enrollment. We can help.
