Recently, I received the following question from a reader:

“I have health insurance through my employer, my husband is self-employed. Will my insurance still be the primary insurance when my husband turns 65 and applies for Medicare?”

Suspecting this could be a complicated question, I went to the medicare.gov website to research the answer. Not too much longer I believe I found the answer in their publication CMS #02179, dated August 2015, “Your Guide to Who Pays First.”

In both the chart that starts on page 6, and in the text on page 12, they refer to such a scenario, answering that when one is 65 or older and covered by a group health plan of either oneself or one’s spouse, and the employer has 20 or more employees, the group health plan pays first, and Medicare second. When the employer has less than 20 employees, then Medicare would be the first payor.

This publication is worth a look because there are many more scenarios to consider. It is available for download on the medicare.gov website here. If you prefer to someone directly, call 1-855-798-2627.
