Obviously not; if they're billing 72 hours a day, that's fraud.
If my procedure goes long because of a complication, I'd still prefer they not wake me up mid-procedure for a credit card and signature.
But it was presented in popular media as if the insurance company was trying to shift the cost of overlong procedures onto the patient, rather than onto the anesthesiologists. Thankfully there was a public outcry and the anesthesiologists won, well-deservedly so considering they must be barely scraping by on a median income of $470,000/year.
The policy even had a path for the anesthesiologist to justify the overrun so that portion could be covered too. No doubt Anthem would scrutinize the justification closely and reject cases where they detect abuse, and the incentives are for Anthem to be too strict, but there was nothing wrong with the policy on its face. These sorts of things are absolutely necessary in order to drive healthcare costs, which are absolutely obscene, down.
