Yes, if you are 65 or older, there may be advantages to enrolling in Medicare before, or instead of, electing COBRA. In general, if you don’t enroll in Medicare Part A or B when you are first eligible because you are still employed, after the Medicare initial enrollment period, you have an 8-month special enrollment period to sign up for Medicare Part A or B, beginning on one of the following dates (whichever comes earlier):
The month after your employment ends; or
The month after group health plan coverage ends based on current employment ends.
If you don’t enroll in Medicare and elect COBRA continuation coverage instead, you may have to pay a Part B late enrollment penalty and you may have a gap in coverage if you decide you want Part B later.
If you elect COBRA continuation coverage and later enroll in Medicare Part A or B before the COBRA continuation coverage ends, the Plan may terminate your continuation coverage. However, if Medicare Part A or B is effective on or before the date of the COBRA election, COBRA coverage may not be discontinued on account of Medicare entitlement, even if you enroll in the other part of Medicare after the date of the election of COBRA coverage.
If you become entitled to Medicare after you’ve signed up for COBRA, your COBRA benefits cease. (But if COBRA covers your spouse and/or dependent children, their coverage may be extended for up to 36 months because you qualified for Medicare.)
