From Philip Moeller writing for PBS News Hour:
Sharilyn – Ind.: My daughter has cancer. She is on disability and Medicare. She is getting married in two months. Can she stay on Medicare or will she have to get on her new husband’s insurance?
Phil Moeller: If she is receiving Medicare through her Social Security disability, it will be her choice whether to continue it or, if available, choose to be covered by her husband’s health plan. She could even keep both, using one as primary and the other as supplemental, depending on which has the best benefits.How many ways can you mislead someone in two sentences? First, Moeller fails to mention the very real possibility that the daughter is on Disabled Adult Child benefits. If so (apart from a very unusual circumstance) marriage will end not just the Medicare but the cash benefits as well. That's more than a theoretical possibility since the question probably concerns a young woman. It is important to warn people who may be at risk about this trap. Second, no, you don't get to choose between Medicare and private healthcare insurance. If you're Medicare eligible, any private healthcare insurance is a secondary payer even if you decline Medicare Part B coverage. In other words, you better have Medicare Part B because your healthcare insurance won't pay for anything Medicare Part B would have paid for. You can't decline Medicare Part A. You don't have to pay a premium for Part A. The young woman needs to be told to ask her new husband's insurer about any options they would offer her but what they offer will only supplement Medicare, not substitute for it.
