How to read the Indiana IDR market
Indiana is one of the largest federal IDR markets in the CMS public files. For a provider group, the useful comparison is rarely the national average. The better question is how a payer behaves in the same state, service mix, and specialty lane.
The tables below show the payer, code, and IDR entity mix that shape Indiana disputes. Use them to spot where an underpaid out-of-network book may deserve a closer NSA workflow review.
