Tests, procedures, medications are already limited by regulation and third party payors. Some things require cash payment now (meds not approved for a specific condition, for example).
I sure don't think this recent legislation is going to improve things, though.
Family member out of the blue after getting a dry socket from tooth pulled began to break out in boils , took 5 doctors to find they had Phempagus, a split gene or what ever that goes back to the time of Moses.
There was only one doctor who believed they could help as the disease is making a come back. This Doctor practiced in Boston and the afflicted came from around the world to see him. One does not die of the disease, the pain is so great they commit suicide.
This doctor knew he could not cure the disease but had found a way to place it in remission.
So expensive were his treatments that medicare would not pay for them. So the Doctor diagnosed his patients with a similar disease that was paid for.
He got caught a few years ago, what a mess for him and his patients.
Then there are the Vets. that get caught perscribing drugs for animals knowing the owners will be taking them,-----A drug for a dog or cat may cost $5.00 a month and the exact same thing for a human $350.00.
Some doctors today prescribe a double dose of medication and instruct the patient to cut them in half so they get an extra months worth.
All this has been going on for years, I wonder how the new and better medical care will indeed bring out American ingenuity between the doctors and their patients to keep costs very low.?
