This wasn't an immediate ER situation, at least directly (yet). More of a if this procedure doesn't get done now, at some point in the relatively near future, there will be multiple ER situations, almost certainly multiple hospitalizations, and one of those might go past the point of no return.
And the insurance still played games. Like, it's in your best interest to pay once and get this situation resolved in a scheduled/controlled manner than wait for multiple emergency hospitalizations AND have to pay for this in an emergency situation...you're probably talking at least 2x cost if not more.
