As someone who's worked on the provider side in different capacities, I can tell you that there could be tremendous value on the provider side.
It's entirely possible that two surgeons with offices next to each other could be getting reimbursed at wildly different rates for their most common procedures for their most common procedures by the same provider.
If you're that provider, you ABSOLUTELY want to know what the surgeon next door is getting paid the next time your group is negotiating with the insurance provider.
