They were considering putting a time limit on the anesthesia they would pay for during procedures. Have a complication and the surgery runs long? Guess you're going to be in intense pain.

You know how in many industries there is a standard amount of time something takes and that determines the standard cost? Like it takes .5 work hours to change your oil so they charge .5 of labor + cost? Well, as I understand it, the plan was to limit the amount of anesthesia they'd cover based on the standard/expected time a medical procedure would take.

"In other words, if a procedure takes longer than expected, patients may wake up to an unexpected bill." https://www.prevention.com/health/a63104965/blue-cross-blue-shield-anthem-insurance-anesthesia-time-limit/

They proposed only paying for a certain amount of anesthesia during surgery, ie you are getting a kidney transplant you only get 45 min of anesthesia the rest wouldn't be covered.
