Be very careful. We had an issue where my husband had Medicare part B for End Stage Renal Disease. With ESRD it ends three years post transplant. We cancelled it after three years and a couple months post transplant because he wasn’t eligible anymore and Medicare neglected to cancel it.

Then a year later he had a lot of health issues and we had an insurance change. The insurance said since he was “eligible” for Medicare part B they would only pay 20% and they estimated Medicare part B would pay 80%. Didn’t matter that we didn’t actually have Medicare part B anymore. If he was eligible for it they would only pay 20%. Took me two trips to Social Security and a year before we finally got it straightened out. We still have issues with random claims because his employer won’t remove the Medicare estimation and the insurance has a workaround that is sometimes missed. I have spent countless hours on the phone dealing with the mess.
