Medicare and COBRA – Rocky Mountain Reserve

The way that COBRA and Medicare coordinate depends on which form of insurance you have first. While it is possible to get COBRA if you already have Medicare, it is not usually possible to keep COBRA if you have it before you become Medicare-eligible. Specifically, whether you can have both COBRA and Medicare depends on which form of insurance you have first.

If you have COBRA when you become Medicare-eligible, your COBRA coverage usually ends on the date you get Medicare. You should enroll in Part B immediately because you are not entitled to a Special Enrollment Period (SEP) when COBRA ends. Your spouse and dependents may keep COBRA for up to 36 months, regardless of whether you enroll in Medicare during that time.

You may be able to keep COBRA coverage for services that Medicare does not cover. For example, if you have COBRA dental insurance, the insurance company that provides your COBRA coverage may allow you to drop your medical coverage but keep paying a premium for the dental coverage for as long as you are entitled to COBRA. Contact your plan for more information.

If you have Medicare Part A or Part B when you become eligible for COBRA, you must be allowed to enroll in COBRA. Medicare is your primary insurance, and COBRA is secondary. You should keep Medicare because it is responsible for paying the majority of your health care costs. COBRA is typically expensive, but it may be helpful if you have high medical expenses and your plan covers your Medicare cost-sharing or offers other needed benefits.

Note: If you are eligible for Medicare due to End-Stage Renal Disease (ESRD), your COBRA coverage is primary during the 30-month coordination period. Be sure to learn about ESRD Medicare rules when making coverage decisions.

Regardless of how many months of COBRA coverage you’re offered — if you’re retiring before or at age 65, you should sign up for Medicare during your seven-month initial enrollment period (IEP), which expires three months after the month in which you turn 65. Or, if you delay Medicare enrollment beyond age 65 because you have health coverage from a current employer (your own or your spouse’s), you should enroll no later than eight months after the employment ends, when your special enrollment period expires.
