Part D Costs

Premium

Most Part D plans require a monthly premium.

Deductible

Some plans have deductibles.

Copays

Many Part D plans require that you pay a fixed copayment each time you fill out a prescription.

Coinsurance

Some Part D plans require that you pay a percentage (coinsurance) of a medication's cost every time you fill a prescription.

Coverage Gap

Although plan designs can vary, most Medicare Part D plans have a cost sharing component commonly known as a coverage gap or “donut hole.” The coverage gap is a temporary limit where you are responsible for all of your drug costs until you reach the plan’s annual out-of-pocket limit. After you reach that limit, you will pay only a small share of your prescription costs for the remainder of the year.

Beginning in 2025, Medicare Part D enrollees will have the option to pay their out-of-pocket Part D prescription drug cost in monthly amounts over the course of the plan year. Part D enrollees can voluntarily opt into the program prior to or at any time during the plan year.

Limits and Considerations

Limits

Most Part D plans have “formularies,” which are lists of covered prescription drugs. Part D plans also have networks of approved pharmacies in your area.

Things to Consider

  • Costs for Part D plans can vary, so choose a plan that meets your needs and budget.
  • Part D insurance premiums may change each year. You will be notified of these changes in the fall prior to the annual Open Enrollment Period.
  • Medicare Part D has a low-income subsidy program, and Medicare beneficiaries may qualify for financial assistance with the cost of their medications based upon their income and assets.
