What's up above isn't completely true.
Medicaid is State based Health care that is 100% paid for by
the State. It's true they don't pay well, sometimes not at
all. Lots of Doctors and Surgeons stopped taking on new
patients since a lot of states don't pay. Texas is a bad state
for doing this.
Medicare is Health insurance from the USA government.
Most Doctors and Surgeons would go out of business if they stopped taking these patients.
There is always exceptions to everything and you do have some hard core doctors that are
trying to make a point and lean hard right and are not taking new patients.
The Surgeons I play golf with tell me that it's Medicare that is holding down the price of Health care.
That they set the market price. The insurance companies normally pay the surgeons a little more.
Most people who become a doctor or surgeon do it to help people, not to become wealthy.
In the end, I think you are right and the doctors will have to keep medicare patients just to keep the practice going, but consider some quotes made after the health care discussion:
After the legislators approved the $500 billion in medicare cuts (which was mostly money owed), half of doctors in multiple states, like Texas, Georgia and others, indicated that they will stop taking medicare patients when the health care law is fully implemented. A third of primary care doctors polled said they will either change fields or retire early.
I don't play golf, but I attend an investing club that involves mostly doctors. Personally, I'm hearing the same types of comments regarding cutting off patients. The friends that I talk to mostly are a rheumatologist and an internist. Both have already stopped taking new referalls for medicare patients.
Medicare drives down the fees that they can charge for procedures. Their period costs still go up, though. What is happening is that they are losing money on medicare patients.
NPR did a piece on the impact of the $500 billion "Cut". I believe that it was rate increases that were technically due for some time period, and legislators just chose to cancel them and call it "savings". They interviewed hospitals that were reeling from unpaid medicare balances as a result.
