Why it is called arbitration
The No Surprises Act created a binding dispute-resolution process for certain out-of-network payment disputes. It is commonly described as arbitration because a neutral certified IDR entity reviews both sides and issues a binding payment determination.
It is different from litigation or a negotiation where the decision-maker chooses a middle number. Federal IDR uses final offers.
Final-offer arbitration
In final-offer arbitration, each party submits one payment offer and supporting information. The certified IDR entity selects the offer that best represents the appropriate out-of-network rate based on the allowable factors.
This structure changes the strategy. An offer that is too low leaves money on the table; an offer that is too high without support may be easier for the IDR entity to reject. The strongest submissions connect the requested amount to the QPA and other statutory factors.
What the arbitrator can consider
The certified IDR entity must consider the qualifying payment amount and may consider other allowable information, including the provider's training and experience, quality and outcomes measurements, the parties' market share, patient acuity, service complexity, teaching status, case mix, scope of services, and good-faith efforts to enter network agreements where applicable.
The best submissions do not simply say the plan underpaid. They explain why the provider's final offer better fits the statutory factors for that service, patient, market, and payer.
- QPA for the item or service
- Provider training, experience, and quality/outcome measurements
- Market share of the provider, facility, plan, or issuer
- Patient acuity and service complexity
- Teaching status, case mix, and scope of facility services
- Good-faith contracting efforts where applicable
What the arbitrator cannot consider
Federal rules prohibit reliance on certain factors, including billed charges, usual-and-customary charges, and public payer rates such as Medicare or Medicaid. Those numbers may be familiar to revenue-cycle teams, but they are not the right anchor for a federal IDR offer.
A provider can still argue for payment above the QPA. The key is to support the amount with allowable evidence rather than prohibited benchmarks.
What happens after the decision
The determination is binding except in limited circumstances. Any amount due from one party to the other must be paid within 30 calendar days after the certified IDR entity issues its determination.
The prevailing party's certified IDR entity fee is refundable under the applicable rules. For portfolio management, teams should track win rate, award multiple, default rate, settlement rate, eligibility loss rate, and time to payment.

FAQ
Is No Surprises Act arbitration the same as federal IDR?
In this context, yes. Federal IDR is the No Surprises Act arbitration process for eligible out-of-network payment disputes.

No. The certified IDR entity selects one of the parties' final offers.
Can billed charges be used to justify the offer?
Billed charges are a prohibited factor in federal IDR and should not be used as the anchor for the arbitration case.
