Had to go back to work to get my wife Heathcare Coverage!

I am 73 years old, on Medicare and SS.
My wife is 62 years old, Real Estate agent.
The RE market is bad, cannot afford to sign up for Healthcare.
I was forced to go back to work with a company that has benefits.
The point I’m trying to make is that to get my wife Healthcare coverage I would have to drop my Medicare and pay full coverage for myself and my wife as my Medicare drops to a supliment coverage that pays very little leaving us with huge medical bills,

Is this a normal practice.

Thank you
