Medicare prescription drug coverage (Medicare Part D)

Español

The Medicare annual open enrollment period is October 15 through December 7.

How does drug coverage work?

Medicare prescription drug coverage (Medicare Part D) pays some of the costs for prescription drugs at participating pharmacies in your area. Everyone with Medicare is eligible for this coverage, regardless of income and resources, health status, or current prescription expenses. The program is voluntary and can be especially helpful for people who have high drug costs and no drug coverage.

You usually pay a monthly premium, which varies by plan, and you may pay a yearly deductible. You will also have additional costs for your prescriptions. These additional costs are called copays or coinsurance, depending on the plan you select.

Medicare sets standard costs for the prescription drug benefit each year. Private companies approved by Medicare offer plans with different costs and selections of prescription drugs. You can select a plan based on the prescriptions you take and select a company that is most effective for you. To reduce your costs, enter your medications on Medicare's secure online Find health and drug plans website. You will pay more if your prescriptions are not in the plan formulary or the plan restricts or limits their use.

How to find a plan

There is no single Medicare drug plan. To get coverage, you must enroll in a Medicare-approved private drug plan. There are at least two ways to get Medicare prescription drug coverage. You can join a Medicare prescription drug plan or you can join a Medicare Advantage plan with prescription drug coverage. 

  • Visit the Medicare Prescription Drug Plan Finder to find a Medicare prescription drug plan in your area. You may either search for plans by entering your Medicare claim number and other personal information or by entering only your ZIP code. Providing your personal information will ensure you receive the most accurate results for the new Medicare drug benefit, how it applies to you, and how much you will pay.
  • Call 800-Medicare (800-633-4227) to get help searching for a plan. Have a list of medications and your Medicare card ready before calling.
  • Contact your local Area Agency on Aging (AAA) at 800-252-9240 for assistance understanding Medicare prescription drug coverage.

Important dates

Medicare beneficiaries who were eligible but have not enrolled in a drug plan can enroll during annual enrollment periods at the end of each year. If you were eligible and did not enroll before the deadline, you will have to pay a financial penalty. The annual Open Enrollment Period for Medicare Part D and Medicare Advantage plans is October 15 through December 7 of each year. Coverage begins January 1.

Individuals newly eligible for Medicare don't need to wait for the next annual enrollment period to enroll in a drug plan. You can enroll during your seven-month initial enrollment period that begins three months before the month you're eligible and ends three months after the month you're eligible.

If you are enrolled in a Medicare prescription drug plan that leaves Medicare, you will have to select a new plan to maintain your prescription drug coverage. You must enroll in a new plan between October 15 and December 7.

If you currently have a Medicare prescription drug plan, the plan will notify you in the fall of each year about its changes for the coming year. It is important to ensure the plan you have still covers your prescriptions and at the best prices.

If you lose "creditable drug coverage" under certain situations, you may qualify to enroll in a Medicare drug plan within 63 days of losing coverage. Upon learning that you will lose prescription coverage, contact Medicare to learn what rights you have to pick up a Medicare prescription plan.

Resources

Protect yourself against fraud

Companies approved to offer the Medicare prescription drug benefit can only contract with state licensed agents to sell their plans. Agents are required to follow state and federal laws when selling these plans. Ask agents to show proof of their license and verify the information by calling our Help Line at 800-252-3439.

If you believe you've been the victim of insurance fraud or attempted insurance fraud, report it to TDI.

File a complaint

If you have a complaint against an agent or company selling Medicare Part D coverage, first file a complaint with the Medicare drug plan. Learn how to file a grievance or appeal.

If you suspect agent misconduct, file an insurance complaint online with TDI.
