Detailing Medicare prescription drug coverage

If you're covered by Medicare, here's some welcome news — Medicare drug coverage can help you handle the rising cost of prescriptions. If you're covered by Original Medicare, some Medicare Cost Plans, Medicare Private Fee-For-Service Plans, or Medicare Medical Savings Account Plans, you can sign up for a Medicare Prescription Drug Plan (Part D) offered in your area by a private company or insurer that has been approved by Medicare. Most Medicare Advantage (Part C) plans also off er prescription drug coverage.

Although prescription drug plans vary, all provide a standard amount of coverage set by Medicare. Every plan offers a broad choice of brand name and generic drugs at local pharmacies or through the mail. However, some plans cover more drugs or off er a wider selection of pharmacies than others, so you'll want to choose the plan that best meets your needs and budget.

How much will it cost?

All Medicare drug plans (both standalone plans and those offered through Medicare Advantage) cap out-of-pocket costs for prescription drugs, and off er enrollees the option to pay costs in monthly installments instead of all at once at the pharmacy.

What you'll pay for Medicare drug coverage depends on which plan you choose. But here's a look at how the cost of Medicare drug coverage for a standard plan is generally structured. All figures are for 2026.

A monthly premium. Most plans charge a monthly premium, which vary considerably. This premium is in addition to the premium you pay for Medicare Part B. You can have the premium deducted from your Social Security check, or you can pay your Medicare drug plan company directly.

If your modified adjusted gross income is above a certain amount, you may also pay a Part D income-related monthly adjustment amount (IRMAA). The Social Security Administration will contact you if you have to pay Part D-IRMAA.

Annual deductible. Plans may require you to satisfy an annual deductible of up to $615. Deductibles vary widely, so make sure you compare them when choosing a plan.

Copayments/coinsurance. Once you've satisfied any deductible that applies, you generally pay no more than 25% of the cost for covered prescription drugs until you reach the annual $2,100 cap for out-of-pocket expenses.

Catastrophic coverage phase. Once your out-of-pocket spending reaches $2,100, you won't pay anything for covered prescription drugs for the rest of the calendar year.

What if you can't afford coverage?

Extra help with Medicare drug plan costs is available to people who have limited income and resources. Medicare will pay all or most of the drug plan costs of people who qualify for help. If you haven't already received a letter telling you that you have automatically qualified for help, you can apply online at the Social Security website, ssa.gov, or at your local Medicaid office.

When can you join?

Individuals new to Medicare have seven months to enroll in a drug plan (three months before, the month of, and three months after becoming eligible for Medicare). Current Medicare beneficiaries can generally enroll in a drug plan or change drug plans during the annual election period (also called the open enrollment period) that occurs between October 15 and December 7 of each year, and their Medicare prescription drug coverage will become effective on January 1 of the following year. If you qualify for special help, you can enroll in a drug plan at anytime during the year. If you have a Medicare Advantage plan, you can switch to another plan with or without drug coverage or switch to Original Medicare (and join a separate Medicare drug plan) during Medicare Advantage's open enrollment period that runs from January 1 through March 31 each year. Certain other events may qualify you for a Special Enrollment Period outside of the annual election period when you can enroll in a plan or switch plans.

If you already have Medicare drug coverage, remember to review your plan each fall to make sure it still meets your needs. Before the start of the annual election period, you should receive a notice from your current plan letting you know of any important plan modifications or additional plan options. Unless you decide to make a change, you'll automatically be re-enrolled in the same drug plan for the upcoming year.

Do you have to join?

No. The Medicare prescription drug benefit is voluntary. However, when deciding whether or not to enroll, keep in mind that if you don't join when you're first eligible, but decide to join in a future year, you'll pay a premium penalty that will permanently increase the cost of your coverage.

There's an exception to this premium penalty, though, if the reason you didn't join sooner was because you already had creditable prescription drug coverage, defined as coverage through another source (such as employer health plan) that was at least as good as the coverage available through Medicare. If you have coverage through another source, talk to your benefits administrator, insurer, or plan before making changes to your coverage. If you drop your coverage, you may not be able to get it back.

What happens after you join?

Once you join a plan, you'll receive a prescription drug card and detailed information about the plan. In order to receive drug coverage, you'll generally have to fill your prescription at a pharmacy that is in your drug plan's network or through a mail-order service in that network. When you fill a prescription, show the card to the pharmacist (or provide the card number through the mail) even if you haven't satisfied your annual deductible, so that your purchase counts toward the deductible and benefit limits.

What if you have questions?
