Not in all cases - it varies significantly for everyone. In my case the hospital, surgeon, anesthesiologist, and some of the assistants were all billed under different systems and as separate entities. The hospital has nothing to negotiate because they're in-network so I had no balance due (meet my out of pocket maximum). The surgeon's assistant was the out of network provider and he was also part of a different practice, so it was his practice billing department that would not budge because they deemed their costs as reasonable and "already discounted".
