I was still working when my wife turned 65. She remained covered with my employer's health insurance and used my employers Aetna insurance plan as her primary medical insurance. Medicare became her secondary insurance. When I turned 65 my employer's insurance was also considered my primary plan and Medicare my secondary plan.
When I retired at 65 1/2 both my wife and I went on a Medicare Advantage plan after looking at all available plans in our area. We chose this plan because it was less expensive than available "medigap" plans in our area and we didn't want to risk going uninsured on the 20% that isn't covered by Medicare. Our Medicare Advantage plan covers everything that was covered by my former employer's plan, includes prescript
ion drug coverage (subject to the "doughnut hole" which is now gradually going away under the ACA), two dental cleanings per year for each of us, and is accepted by all of the doctors we were already using at our university medical center / teaching hospital.
If you haven't already done so, I suggest you go to the government's medicare site where you can compare all of the Medigap, medicare prescript
ion, and Medicare Advantage plans offered in your area. When comparing plans (especially some of the "free" or low cost ones, be sure to check to see if your doctors accept those plans and also carefully compare your potential maximum out-of-pocket expenses.
We opted for a plan that costs about
$125 per month for each of us because it has minimal out-of-pocket expenses for both local and out-of-network providers. One of the "free" plans we looked at wasn't accepted by our local doctors and could have exposed us to annual maximum out-of-pocket expenses of over $8,000 each. We travel quite a bit, so on a plan like that, we could end up on the hook for more than $16,000 if, say, we had a traffic accident that put us both in the hospital for a couple of days.
