This is a straw man argument. Yes they shouldn't deny a prescription if your doctor says you need it.

What I'm talking about is capping the costs of a supporting doctor for a surgical procedure. From my quick research, there is no significant cost basis for surgery running longer than planned besides the anesthesiologist's time. So the doctor would make $400k instead of $500k per year.

Here is some perspective. The anesthesiologist's bill for my wife's colonoscopy in 2023 was $2k. This is a routine procedure that takes less than an hour. Also, the place was just filled with patients and there was one guy handling them all.
