How to file federal IDR step by stepA guide for surgical billing teams.

Filing IDR is not complicated, but it is unforgiving on timing. The process rewards practices that move quickly and punishes the ones that let a window close.

Start with eligibility. The claim must be out of network and within the scope of the No Surprises Act. Plan type matters here: self funded employer plans route to federal IDR everywhere, while fully insured plans may route to a state process in states that have one.

Next comes open negotiation. This is a 30 business day period where you and the plan try to settle directly. Most do not settle, but the period is required before IDR.

Then the window that decides everything. After open negotiation closes, you have only four business days to initiate IDR. This is where most recoverable claims quietly die. A practice gets busy, the window passes, and the underpayment becomes permanent.

Once initiated, you submit one offer backed by benchmark data and prior determinations on the same code. The arbitrator picks one number.

These five steps are the easy part to understand. The hard part is running them across a full claim volume without a single window slipping, and that is the part that loses practices money. Sydra builds the packet, cites the supporting determinations, files one claim per CPT, and keeps both clocks visible for every claim at once, so knowing the steps turns into actually getting paid.
