Hello, I am turning 65 and on COBRA. My (3 years younger = 62) husband is also on COBRA with me, so can he get another extension, since our COBRA is at the end of our 18 months?

No because the medicare entitlement did not enable him to get COBRA a second time.

Dependents Extending Medicare

My 18 months of COBRA ended March 31st, 2011. I became eligible for medicare April 1, 2011 (My 65th birthday was on March 21). Is my wife eligible for another 18 months of COBRA?

I would also like to know, am i elgiable for cobra insurance through my employer even if i have medicare?

You should be able to elect Cobra but it's is always very expensive when you have pay the entire premiums alone. Medicare, With medicare part A and part B and then a supplemental policy which cost a lot less than Cobra and would cover most of your health insurance expenses. Medicare would become your primary insurance and then a good medsup policy would take care of the balance. Medicare pays very little due to the contractual adjustment the hospital are required to write off. Having Cobra as your primary insurance and Medicare secondary is not as good.
