Why anesthesia billing needs an IDR view
Billing teams usually start with eligibility, coding, documentation, and payer policy. For protected out-of-network claims, that is not enough. The remaining payment dispute may depend on QPA, open negotiation timing, the correct state or federal route, and whether the economics justify filing IDR.
The useful question is not whether a national average looks favorable. It is whether your payer, state, and code mix behaves like the disputes below.
