When I priced my stomach surgery and the surgery to remove the mass on my leg, both were priced in the tens of thousands. Stomach surgery was, IIRC, about 30,000.
That was before I had insurance. The bills I got, the ones that the insurance paid, were a fraction of the cost because the Insurance company had a contract with the surgeons.
Opposite story here.
I had two MRIs done after a car accident. The one from the hospital charged the insurance company $4500.
A year later I paid cash for an MRI at a private clinic. $515. Newer machine, better service. Same scan.
I must now wait 2 months for my first appointment after losing my insurance (it went up 90%). I will probably go pay cash so I can get my prescription refilled before I actually run out.
I have never needed public assistance until ACA. It will be temporary.
