Providing care is only one part of the financial equation. Healthcare organizations must also make sure the payment they receive accurately reflects the services delivered.
For certain out-of-network claims, the initial payment from a health plan may be lower than the provider believes is appropriate. When negotiation does not resolve that difference, Independent Dispute Resolution, commonly called IDR, may provide a formal path to challenge the payment amount.
IDR is a specialized part of revenue recovery. It requires more than submitting a claim and waiting for a decision. The organization must identify the correct dispute pathway, confirm that the claim is eligible, meet strict deadlines, prepare a strong case, and follow the payment through resolution. When any part of that process breaks down, reimbursement can be delayed or lost.
What Is Independent Dispute Resolution in Healthcare?
Independent Dispute Resolution is a process used to resolve certain payment disputes between healthcare providers or facilities and health plans. It applies to eligible out-of-network items and services and keeps the patient outside the dispute over the payment amount.
The federal process was established under the No Surprises Act. The law protects patients from many unexpected out-of-network bills while creating a separate process for providers, facilities, and health plans to resolve payment disagreements. Depending on the claim, plan type, service, and applicable state law, the dispute may follow either a federal or state IDR process.
IDR is not a replacement for every denial or appeal. Coverage, authorization, medical necessity, coding, and other claim issues may require different forms of follow-up. IDR is specifically designed for eligible out-of-network payment disputes. That makes accurate claim review and pathway selection critical from the beginning.
Why IDR Matters to Healthcare Providers
An underpaid claim does not become less important simply because the original claim was processed. If eligible payment differences are repeatedly accepted or written off, the effect compounds across the organization.
IDR gives providers a structured way to pursue payment when the parties cannot reach an agreement directly. A disciplined IDR strategy can help an organization:
- recover revenue tied to eligible out-of-network services;
- reduce avoidable write-offs;
- identify recurring payor and reimbursement patterns;
- bring greater accountability to payment follow-up; and
- protect the cash flow needed to support staff, operations, and patient care.
The scale of the federal program shows that IDR is no longer an uncommon edge case. According to the Centers for Medicare & Medicaid Services’ Federal IDR reports, more than 7 million disputes were initiated between the portal’s launch on April 15, 2022, and July 31, 2026. During that period, more than 1.16 million disputes were closed as ineligible. Those numbers reinforce two realities: payment disputes are widespread, and successfully navigating eligibility is a meaningful operational challenge.
Where IDR Fits into the Revenue Cycle
As discussed in What Is Revenue Cycle Management? Building Stronger Systems to Protect Healthcare Revenue, revenue cycle management connects the clinical, operational, and financial processes that move an account from patient registration through final payment.
IDR sits near the back end of that cycle, after care has been delivered, the claim has been submitted, and the health plan has issued an initial payment or notice of denial for an eligible out-of-network item or service. It is part of the broader work of payment recovery, alongside claim follow-up, denial management, appeals, prompt-pay enforcement, and payor negotiation.
A strong IDR process also depends on the work that happened earlier. Accurate patient and plan information helps determine which rules apply. Complete documentation and correct coding support the payment position. Timely claim monitoring allows the team to identify an eligible dispute before the filing window closes. IDR may occur late in the revenue cycle, but its success is connected to the integrity of the entire system.
How the Federal IDR Process Works
- Identify the claim and confirm eligibility
The team reviews the item or service, plan, initial payment or denial, dates, location, claim information, and applicable law. The first question is not simply whether the payment appears low. It is whether the dispute is eligible for Federal IDR and whether a state process or another recovery pathway applies instead. - Begin open negotiation
The provider or health plan initiates an open negotiation period. The parties then have 30 business days to try to agree on an out-of-network payment amount without moving into formal IDR. - Initiate IDR if negotiation is unsuccessful
If the parties do not reach an agreement, either party may initiate the Federal IDR process. Under current federal guidance, the initiation window is generally four business days after the open negotiation period ends. Current notices and extensions should always be reviewed before relying on a deadline. - Submit offers and supporting information
The parties select, or are assigned, a certified IDR entity. Each party submits a payment offer and information supporting its position. The certified entity then selects one of the two offers. This final-offer structure makes case preparation and a defensible payment position especially important. - Track the determination and final payment
The work does not end when a decision is issued. The determination, payment obligation, fees, and account status must be monitored and reconciled. CMS states that the parties must follow the certified entity’s decision and that payment must be made within 30 calendar days.

Federal IDR vs. State IDR
Federal and state IDR processes share a common purpose, but they are not interchangeable. Which route applies depends on several factors, including how the health plan is funded, where the service was provided, the type of service, and whether an applicable state law determines the out-of-network payment amount.
Self-funded plans generally fall under the federal process because they are typically governed by federal law. Fully insured plans may fall under a state process when the state has an applicable payment dispute mechanism. If a state law does not apply to the particular plan or service, the federal process may govern instead.
State requirements can vary substantially. Filing windows, portals, eligibility standards, fees, documentation, mediation procedures, and arbitration rules may differ by jurisdiction. A claim submitted through the wrong pathway can cost time, add administrative work, or jeopardize the opportunity to recover payment.
This is why plan and claim classification must happen before filing, not after a dispute has already been rejected.
Why IDR Is Difficult to Manage at Scale
IDR is both deadline-driven and detail-heavy. A healthcare organization may have a valid payment concern but still lose the recovery opportunity because the claim was routed incorrectly, an open negotiation notice was incomplete, documentation was not organized, or a filing deadline passed.
The rules also continue to evolve. In May 2026, federal agencies finalized operational changes to the Federal IDR process, including updates related to payor communications, open negotiation, batching, eligibility review, fees, and a future IDR registry. Some provisions depend on additional guidance and system implementation, which means healthcare organizations need an active process for monitoring changes rather than relying on an outdated checklist.
At scale, effective IDR management requires clear ownership, reliable claim identification, accurate deadline tracking, organized case documentation, consistent portal work, and follow-through after the determination. It also requires the ability to see patterns across claims. Repeated underpayments, eligibility problems, or delays may reveal a larger revenue cycle issue that should be addressed upstream.
How Gryphon Healthcare Supports the IDR Process

Organizations can use Gryphon Healthcare’s Federal and IDR services as specialized support or as part of a broader revenue cycle partnership. The goal is the same: protect earned revenue, reduce the burden on internal teams, and build a more reliable path from claim submission to final payment.
A Stronger Recovery Process Starts with Visibility
Healthcare leaders do not need to assume every low payment belongs in IDR. They do need a reliable way to identify eligible claims, understand why revenue is being lost, and direct each account into the right recovery process.
The most useful starting questions are straightforward:
- How are eligible out-of-network underpayments identified today?
- Who determines whether federal IDR, state IDR, an appeal, prompt-pay action, or another pathway applies?
- Are open negotiation and filing deadlines tracked consistently?
- How often are disputes lost to ineligibility, incomplete information, or missed follow-up?
- Can leadership see recovery results and recurring payor trends?
The answers help show whether the problem is an isolated backlog or a broader gap within the revenue cycle.
Strengthen the Recovery Side of Your Revenue Cycle
If eligible out-of-network claims are being underpaid, delayed, or written off because your team lacks the time or specialized expertise to pursue them, Gryphon Healthcare can help identify the right recovery path and manage the process from review through resolution.
Frequently Asked Questions
What does IDR mean in healthcare?
IDR stands for Independent Dispute Resolution. It is a formal process used to resolve certain out-of-network payment disputes between healthcare providers or facilities and health plans.
Is IDR the same as a claim appeal?
No. A traditional appeal may address issues such as coverage, authorization, coding, or medical necessity. IDR addresses the payment amount for eligible out-of-network items and services under applicable federal or state rules.
What is the difference between federal and state IDR?
The applicable pathway depends on the plan, service, location, and governing law. Self-funded plans generally use Federal IDR. Fully insured plans may use a state process when an applicable state law determines the out-of-network payment amount.
Does the patient participate in IDR?
No. For services protected under the No Surprises Act, the patient is generally limited to the applicable in-network cost-sharing amount. The provider or facility and the health plan resolve the payment dispute separately.
Where does IDR fit within revenue cycle management?
IDR is a payment-recovery function near the back end of the revenue cycle. It follows claim submission and payor adjudication and depends on accurate information, documentation, coding, eligibility review, and timely claim monitoring across the broader revenue cycle.
