6 weeks after the procedure I was sent another bill for 30% higher

I was quoted (after they reviewed my insurance) and charged one price. Six weeks after the procedure I was sent another bill for 30% higher. The cost was already on the high side, and the procedure was nothing special. If I had known it was going to cost 30% more I would have gone somewhere else. Their billing department was like talking to a brick -- no explanation other that "this is how we do it." So beware, how they do it is by ripping you off.
