That definitely seems the case.
I actually got them to go back and cover one procedure and I had another 12 days later that they say it was the job of the provider to apprise me of changes and the provider is like nuh uh....
But instead of reliving the cyclical nature of these conversations, seems I'm just gonna pay out of pocket and now I'm collecting all new providers...which kind of is a blessing in disguise, but ugh...
