The short answer

No. COBRA is not considered active employer coverage for Medicare purposes. Relying on COBRA instead of enrolling in Medicare when you are first eligible can result in late enrollment penalties and gaps in coverage.

The full explanation

This is one of the most common and costly mistakes people make. COBRA lets you keep your former employer's health insurance for a limited time after leaving a job, but Medicare treats it very differently than it treats active employer coverage.Active employer coverage, for Medicare's purposes, means you are currently working and covered through your own job or a spouse's current job. That kind of coverage gives you a special enrollment window after you stop working, so you can delay Medicare without penalty.COBRA does not qualify. The moment you turn 65 and become eligible for Medicare, COBRA stops being a valid reason to delay enrolling. If you miss your Initial Enrollment Period because you assumed COBRA would protect you, Medicare can hit you with a late enrollment penalty on Part B, which adds a permanent percentage increase to your monthly premium. And that penalty lasts for as long as you have Part B.The short version: use COBRA only as a bridge if you need it, but do not let it delay your Medicare enrollment past your Initial Enrollment Period. If you are in this situation right now, talking to a licensed agent or your local SHIP counselor soon is important. The rules have real financial consequences.

In 

Ohio

 specifically

In Ohio, Medicare plan options usually vary by county, and metro areas like Franklin, Cuyahoga, Hamilton, and Summit often have more plan competition than smaller counties. Ohio beneficiaries should check provider and hospital networks carefully before enrolling, because a plan can be available in your county without including the doctors or systems you prefer. Ohio residents can get free Medicare counseling through OSHIIP, the Ohio Senior Health Insurance Information Program, for help with plan comparisons, enrollment rules, appeals, and savings programs.

What this means for you

For you, this means if you are on COBRA and turning 65, you likely need to enroll in Medicare right away to avoid penalties that could follow you for the rest of your life.
