CMS cuts the IDR filing fee to $15 and now allows batching. Here's what changed.The final rule of May 28, 2026, effective June 11, 2026: $15 fee, batching permitted, IDR Gateway rolling out.

On May 28, 2026, CMS finalized a new rule overhauling federal IDR, jointly with the Departments of Labor, Treasury, and the Office of Personnel Management. Two changes affect how your practice should think about filing: the administrative fee dropped from $115 to $15 per dispute, and batching multiple claims into one submission is now explicitly permitted to lower costs and speed resolution.

What changed

The rule reduces the standard administrative filing fee from $115 to $15, a meaningful drop for any practice weighing whether a lower value claim is worth disputing. CMS also finalized permission to batch multiple related claims into a single IDR submission, aimed at reducing the backlog that has built up since the process launched. CMS cites more than 5 million disputes sent to IDR since April 2022. A new centralized platform, called IDR Gateway, is rolling out in phases to let providers initiate disputes, track case status, and manage the process in one place. Payers will be required to register on the Gateway, which should make it easier to confirm which party you are disputing with.

What this means for your practice

The fee was never the reason large claims went unfiled. At $115 a side it was the reason small ones did. A $2,000 underpayment carried an administrative cost that made pursuing it marginal; at $15 it does not.

The practical effect is that the floor on what is worth disputing dropped, and most billing workflows have not been rebuilt around that.

The IDR fee dropped to $15. Here's what it means for your claims.

CMS cut the federal IDR filing fee from $115 to $15 and now permits batching claims. Dr. John Abrahams, MD explains the batching tradeoff and how Sydra handles it.

Transcript

CMS just cut the IDR filing fee from $115 to $15, and made a change that could actually hurt your win rate if you use it wrong. As of the May 2026 federal rule, filing a federal IDR dispute costs fifteen dollars instead of a hundred and fifteen. CMS also started allowing practices to batch multiple claims into one submission, to speed things up and cut costs across the system. Here's what that means in practice. If you batch ten high value codes into one submission, the arbiter picks one offer for the whole batch. One offer. If it's not selected, all ten codes lose together. File them one at a time, and each code stands on its own. In my own practice, that's the difference between winning eight or nine out of ten, or risking all ten on one roll. That's why Sydra still files one claim per CPT by default. But batching is real now, it's sanctioned, and there are cases where it makes sense: lower value codes, claims from the same encounter with strong overlapping evidence. So we put the decision in your hands. Every submission, you choose. See how it works on a real claim from your specialty. Free 15-minute call, link below.
