I've seen 'this was Big Anesthesia whining that they can't bill for random bullshit anymore,' but... I keep coming back to 'there was no audit and therefore no proof that things need to be changed.'
Also, what was said might have been 'we're changing billing standards for when things run long,' but what people heard was 'we're going to tell them to let you wake up on the table.'
why would the anesthesiologists care, they'd get paid either way. the punishment would fall to the patient's wallet and they have no control over what the anesthesiologists bill them for
you also never know what might actually happen on an operating table. my last operation ran longer than expected because they ran into issues, and they put all of that info in the surgical notes, descriptively
(And like I said, they can say 'we want to streamline the billing' or whatever, but what people will hear is 'we're going to tell them to let you wake up on the table.')
