What affects Medicare Part D costs each year?

Several factors can play into determining the cost of a Medicare Part D plan, such as:

  • Drug formulary
    Each Medicare Part D plan contains a formulary, which is a list of drugs covered by the plan.

    Covered drugs are divided up into different tiers. Generic drugs are typically on lower tiers and cost less, while brand name drugs and specialty drugs are typically on higher tiers and cost more.

  • Local competition
    Medicare Part D plans are sold by private insurance companies. These insurance companies are generally free to set their own premiums for the plans they sell.

    Medicare Part D plan costs in any particular area may depend partly on the cost of other plans being sold in the same area by competing carriers.

  • Cost-sharing
    Some Medicare Part D plans have deductibles and copayments or coinsurance.

    The cost of your Part D premium may depend on the amounts of coinsurance or copayments you pay with your plan, as well as whether or not your plan has a deductible.

Your Part D deductible is the amount that you must spend out of your own pocket for covered drugs in a calendar year before the plan kicks in and begins providing coverage.

Copayments and coinsurance are the amounts that you must pay once your plan’s coverage does begin.

A copayment is usually a fixed dollar amount (such as $5) while coinsurance is most often a percentage of the cost (such as 20 percent). Plans might have different copayment or coinsurance amounts for each tier of drugs.

The Medicare Part D “donut hole” coverage gap

After 2020, Medicare Part D plans have a shrunken coverage gap, or “donut hole,” which represents a temporary limit on what the plan will cover for prescription drugs.

You enter the Part D donut hole once you and your plan have spent a combined $5,030 on covered drugs in 2024.

Once you reach the coverage gap, you will pay up to 25 percent of the cost of covered brand name and generic drugs until you reach total out-of-pocket spending of $8,000 for the year in 2024.

Once you reach $8,000 in out-of-pocket spending, you are out of the donut hole and enter “catastrophic coverage,” where you won't pay a copayment or coinsurance payment for your covered drugs for the rest of the year.

Extra Help for Medicare Part D

Extra Help is a governmental assistance program that helps lower income individuals more easily afford Medicare Part D. Extra Help helps pay for Part D premiums, deductibles and copayments/coinsurance.

Medicare Advantage plans are an alternative to Original Medicare (Part A and Part B).

Medicare Advantage plans (also called Medicare Part C) provide all of the same coverage as Medicare Part A and Part B and can include some benefits that Original Medicare doesn’t cover, such as prescription drug coverage.
