Is COBRA considered creditable coverage for Medicare, or do I still need to sign up for Part B?
Answered by 3 licensed agents
If you are 65 or older and your employment ends, your 8-month Special Enrollment Period for Part B begins when the job or active employer coverage ends — even if you elect COBRA afterward. Do not wait until COBRA ends to enroll in Part B.
Prescription coverage is different.
Your COBRA plan may include prescription coverage that Medicare considers creditable, meaning it is expected to pay at least as well as Medicare Part D. The plan is required to tell you whether the drug coverage meets that standard.
If the COBRA drug coverage is creditable, you can generally delay Part D without a late-enrollment penalty while that coverage continues.
If it is not creditable, do not rely on COBRA as your prescription coverage. Once you go 63 days or more without Part D or other creditable drug coverage, you can begin accumulating a Part D late-enrollment penalty. The penalty generally increases for every month you went without creditable coverage and can stay with you for as long as you have Medicare drug coverage.
That is why I would confirm the drug coverage before the employer plan ends. If it is not creditable, use your Medicare enrollment opportunity to get Part D or a Medicare Advantage plan that includes prescription coverage rather than waiting for COBRA to run out. Medicare also provides a Special Enrollment Period when creditable drug coverage is lost or is determined to no longer be creditable.
The simple rule is: COBRA does not stop the Part B clock, and non-creditable COBRA drug coverage does not protect you from the Part D penalty.

No. COBRA does not count as creditable coverage for delaying Medicare Part B, even though it may feel like "still having employer coverage." The Social Security Administration is explicit on this point: coverage based on current employment excludes COBRA, retiree health coverage, VA health coverage, and individual Marketplace coverage. If you're leaving a job and electing COBRA, you generally still need to enroll in Medicare during your Initial Enrollment Period — the seven-month window centered on your 65th birthday.
This trips people up because the logic feels backwards. While you were actively working, your employer coverage genuinely was creditable, and you could delay Medicare without penalty. COBRA is different: it's coverage that continues after your employment ends, and Medicare's rules don't treat it the same way.
Three scenarios matter here. If you have COBRA first and then become eligible for Medicare, your COBRA typically ends automatically at 65, and you still need to enroll during your Initial Enrollment Period. If you already have Medicare and then become eligible for COBRA, you can elect it, but since Medicare pays primary, COBRA may only cover a limited remainder — often making Medigap the better value. If you're still working past 65 with active employer coverage, that coverage is genuinely creditable, and once it ends you get an eight-month Special Enrollment Period.
