  • Medicare does cover prescription drugs. Which drugs and how they’re covered depend on your plan choices.

  • People with Original Medicare buy prescription drug coverage through a stand-alone Medicare Part D plan.

  • People with Medicare Advantage generally get prescription drug coverage through their Medicare Advantage plan.

  • Certain outpatient prescription drugs administered in medical offices or hospitals might be covered by Medicare Part B, instead.

Over 80% of Medicare beneficiaries have outpatient prescription drug coverage, according to data from the Centers for Medicare & Medicaid Services (CMS)

. Everyone with Medicare can get prescription drug coverage, but the specific method varies depending on whether you have Original Medicare or Medicare Advantage.

People with Original Medicare (Part A and/or Part B) get prescription drug coverage by enrolling in a stand-alone Medicare Part D plan sold by a private insurance company.

People with Medicare Advantage generally have prescription drug coverage through the Medicare Advantage plan, so they can’t enroll in a separate Part D plan

.

In either case, plans’ drug formularies, out-of-pocket costs and pharmacy networks can differ significantly, so it’s important to compare options with your personal situation in mind.

Here’s what you should know about how Medicare covers prescription drugs.

What Medicare Part D plans cover

Medicare sets certain rules for how prescription drug coverage works, but individual insurance companies and plans determine what specific drugs they cover and how

Centers for Medicare & Medicaid Services. What Medicare Part D Drug Plans Cover. Accessed Jun 20, 2024.
. The list of a plan’s covered drugs is called a formulary. It’s crucial to check a plan’s formulary before you enroll.

Formularies are generally organized into tiers with different copays, coinsurance and/or deductibles according to the tier. Check where your drugs fall on the formulary to see what you’d owe for your prescriptions. You should also check each plan for restrictions on drug coverage, such as requirements that certain drugs be approved in advance by the insurer.

If your plan doesn’t cover a needed drug, it’s possible for you and/or your health care provider to request an exception. If you or your provider can demonstrate that it’s medically necessary, the plan might cover the drug or bill you as if the drug were on a less expensive formulary tier

Does Medicare Part B pay for prescription drugs?

Most outpatient prescription drugs are covered by Medicare Part D. But Medicare Part B, which covers outpatient (non-hospital) medical care, covers certain outpatient drugs you don’t administer yourself, such as infusions you get in a doctor’s office or in an outpatient department in a hospital

What you’ll pay for prescriptions

Premiums

Most stand-alone Medicare Part D plans have premiums. Part D plans have an average total monthly premium of $55.50 in 2024, according to CMS

Centers for Medicare & Medicaid Services. CMS Releases 2024 Projected Medicare Part D Premium and Bid Information. Accessed Jun 20, 2024.
.

Medicare Advantage plans with prescription drug coverage include the cost of that coverage in the plan’s premium — you don’t pay separately for Part D benefits.

With either kind of coverage, people with very high income might owe an additional amount known as an income-related monthly adjustment amount (IRMAA)

Centers for Medicare & Medicaid Services. Monthly Premium for Drug Plans. Accessed Jun 20, 2024.
.

In 2024, beneficiaries whose 2022 income exceeded $103,000 (individual return) or $206,000 (joint return) will pay an added amount on top of plans' premiums ranging from $12.90 to $81 per month, depending on income.

Out-of-pocket costs

In addition to any premiums, you might also pay out-of-pocket costs such as copays, coinsurance and deductibles. These costs vary depending on the plan, drug and pharmacy where you fill the prescription.

You can enter your information on Medicare.gov to compare what different plans would cost for your specific drugs and pharmacies.
