If you are approaching 65 and currently covered through continuation health insurance, there is a critical decision that requires your attention before that birthday arrives. Federal law allows people to keep their employer group health plan coverage after losing a job or experiencing certain other life events, but COBRA does not exempt you from Medicare enrollment requirements, and the consequences of missing the enrollment window are both financial and permanent.
Understanding how these two programs interact is essential for anyone navigating this transition.
What COBRA is and who qualifies
The Consolidated Omnibus Budget Reconciliation Act, commonly known as COBRA, is a federal law that permits workers and their dependents to continue employer-sponsored group health coverage for a limited time after the coverage would otherwise end. You may be eligible for this coverage if you leave your job for any reason, whether voluntarily or involuntarily.
COBRA generally applies to employers with 20 or more employees. Many states have enacted what are sometimes called mini-COBRA laws that extend similar continuation rights to employees of smaller organizations with fewer than 20 workers, so coverage options may exist beyond the federal program depending on where you live.
Standard continuation coverage runs for 18 months in most cases, though 36-month coverage may be available in certain qualifying circumstances. Coverage through this program is also available beyond job loss. A divorce or legal separation backed by a court order can make you eligible, which is a provision that affects many people during life transitions that coincide with approaching retirement age.
Why turning 65 changes everything
The mistake that costs people money, sometimes thousands of dollars in lifetime premium surcharges, is assuming that the continuation coverage delays or replaces the Medicare enrollment obligation. It does not.
When you turn 65, you become eligible for Medicare. If you are not covered by an active employer group health plan at that point, you must enroll in Medicare during your initial enrollment period, which begins three months before your 65th birthday month and ends three months after it. The program is not considered active employer group health plan coverage under Medicare’s rules, which means continuation coverage does not give you an extension on that window.
If you miss the initial enrollment period because you thought the continuation coverage was sufficient, you may face a late enrollment penalty on Medicare Part B, which covers outpatient care. That penalty is 10 percent of the Part B premium for every 12-month period you were eligible but did not enroll, and it continues for as long as you have Part B. The penalty does not go away.
The situations most likely to create confusion
People who lose their jobs close to their 65th birthday and elect continuation coverage to bridge the gap are the most common group to encounter this issue. Continuation coverage works well as a temporary bridge between jobs or before retirement healthcare options kick in, but it can create a false sense of security about enrollment timing.
If you retired early, never enrolled because you had employer coverage, and then lost that coverage and elected COBRA, your Medicare clock may already be running depending on when you left active employment. The specific rules about what counts as qualifying employer coverage and when your special enrollment period begins can be complex.
What to do
If you are approaching 65 and currently on COBRA, contact Social Security or visit Medicare.gov to understand your enrollment timeline. Do not assume your continuation coverage satisfies the Medicare requirement. The two programs serve different purposes and operate under different rules.
Enrolling on time protects you from permanent premium increases that compound over the years. Missing the window because of a misunderstanding about COBRA is avoidable with the right information.
