Dear Marci,
When I become eligible for Medicare, what do I need to know about signing up for Part D?

Dear Isaac,
When you become eligible for Medicare, you can sign up forPart D, the prescription drug coverage part of Medicare, as soon as you are enrolled in either Medicare Part A or Part B. You do not necessarily have to sign up for Part D, but you may face a late enrollment penalty if you do not sign up when you are first eligible. That said, if you have creditable coverage (discussed below), you can delay signing up for Part D and will not have to pay a late enrollment penalty.
Creditable coverage is coverage that is, on average, as good as or better than the Medicare drug benefit. You should receive notice from your plan or employer every year informing you whether your drug coverage is creditable for Part D. If you do not receive this notice, you should contact your plan or employer’s benefits administrator.
Creditable coverage can be from:
- Current employer coverage from you or your spouse
- Former employer coverage from you or your spouse, such as retiree insurance
- Federal Employee Health Benefits
- Military coverage, such as TRICARE for Life (TFL) or Veterans’ Affairs (VA) benefits
If you currently have creditable coverage that you like, you may want to keep it. If you join a Medicare prescription drug plan, you may lose your creditable drug coverage and be unable to get it back later. Ask your employer or benefits administrator what will happen to your other drug coverage if you join a Part D plan.
Although you will not face a Part D late enrollment penalty if you have creditable drug coverage, if you do not sign up for Part D when you are first eligible, you will have to wait until Fall Open Enrollment (October 15 through December 7 every year) to do so— unless you have a Special Enrollment Period (SEP). An SEP allows you to enroll in a Medicare Part D plan at other times during the year. For example, if you lose your creditable drug coverage through no fault of your own, you will have an SEP to enroll in Medicare Part D. This Special Enrollment Period lasts for two months after the month you lost creditable drug coverage. For example, if you have creditable drug coverage through your current employer, and you lose that coverage in May because you stopped working, then you would have until the end of July to sign up for Part D. Other SEPs apply to different circumstances and have different durations.
Remember, if you are eligible for Medicare but have prescription drug coverage that you want to keep, it is important to find out if the coverage is creditable. You should keep records of your creditable drug coverage for as long as you have it so that you can provide proof of coverage if needed.
