It’s single payer from the patient’s point of view.
And Medicare is heavily subsidized by the government. I once worked as a consultant to a Medicare Managed Care plan. They were charging the patient anywhere from 0 to $120 a month depending on what the plan covered. But they were getting $1000 a month per patient from the government.
There’s many reasons not to do this, but if they do, I hope they allow supplemental plans for things that Medicare doesn’t cover.
“It’s single payer from the patient’s point of view.”
Then why do they need to pay for a Supplemental Plan?
