Here's a quick way to evaluate whether an Independent Dispute Resolution (IDR) vendor is worth the cost. Hand a single eligible out-of-network claim to someone on your team and have them take it through the No Surprises Act arbitration process from start to finish.
They'll likely win, and recover more than the initial payment. They'll also see how much has to happen to get there.
Take certified IDR entity (IDRE) selection: the provider proposes one, the payor rejects it, counters with another, and the two trade names until they either agree or the system assigns one at random. Every one of those moves arrives as an email notification, on a tight deadline. And that's one step, on one claim, before anyone has argued the actual dispute. Multiply that across every stage, and the work isn't hard so much as relentless.
In other words, one dispute is manageable. A thousand becomes an operating model.
That's where the decision changes from whether IDR is worth pursuing to whether you can run it consistently and effectively, at a scale that makes financial sense for the organization.
This article provides a framework for answering that question. It examines the four factors that determine whether providers are better off building an in-house IDR capability or partnering with a vendor.
The four factors that determine whether to use an IDR vendor
Building an IDR program is an investment in a new organizational capability. Before committing to it, providers should weigh four factors that determine whether building internally is justified, or whether partnering with a vendor is the better path.
1. Volume economics: “Can IDR pay for itself?”
The first question is the foundational one: how many IDR-eligible claims does your organization generate on a recurring basis?
That figure determines whether the economics of building an in-house operation can work. Eligible claims may proceed through the federal No Surprises Act IDR process or an applicable state dispute resolution program, which may have different parameters, but the underlying question is the same: is there enough recurring volume to justify dedicated infrastructure?
Every IDR program has a break-even point. Building internally means upfront investment in people, technology, and operational processes. Partnering replaces most of that fixed cost with a vendor fee, often under a contingency model.
Each dispute also carries its own costs: an administrative fee, and the IDRE fee, the latter of which the losing party pays. On lower-dollar claims, particularly in specialties like pathology and laboratory services, those fees can swallow much of the recovery if claims are filed one at a time. Batching similar claims into a single dispute spreads the cost across multiple, and often makes IDR viable where it otherwise wouldn't be. Doing that well at scale is its own capability.
Once claim volume reaches a certain threshold, the economics change. A provider with the team, the data, and the working capital to run the process at a strong win rate can absorb the fixed cost and keep the full margin. That's the real argument for building in-house. The remaining three factors test whether a provider can clear that bar.
2. Compliance execution: “Can we run IDR the right way?”
Volume economics tell a provider whether building IDR capabilities in-house can pencil out. Compliance execution asks whether they can run the process correctly, because the cost of getting it slightly wrong is often the claim itself.
IDR is a deadline-driven process, and the deadlines are unforgiving. After an initial payment or denial, there's a 30-business-day open-negotiation window, then a four-business-day window to initiate IDR. If you miss either, the dispute is off the table, along with your shot at fair reimbursement.
And the deadlines are the visible part. A functioning IDR operation has to screen eligibility based on ambiguous signals before filing, route eligible claims to the federal process or applicable state program, carefully batch claims to optimize ROI, build an evidence-based offer and supporting documentation for each dispute, promptly respond to IDRE requests for information, and manage cases that resolve along the way. Each is a distinct workflow with its own rules, and they all have to run together (and keep running as the rules change).
These are all potential failure points with consequences that can't be easily reversed. An eligibility error invites payors to challenge the claim and can lead IDREs to close it administratively before anyone argues its merits. A single claim under the wrong health plan group number can jeopardize an entire batch. And sloppy upstream work shows up downstream, because the awards payors don’t pay are usually the ones built on shaky eligibility.
The economics, then, are only a small part of the equation. A provider with the volume to justify building still has to decide whether a compliant, deadline-perfect IDR operation is a capability worth owning, or one better handed to a vendor that runs it at scale. Neither answer is wrong. But the bar is high, and clearing it only partway is measured in forfeited claims and uncollected awards.
3. Data and expertise: “Can we win IDR consistently?”
The first two factors ask whether an organization can run an IDR program. This one asks a different question: can it consistently make the right decisions once a dispute reaches arbitration?
IDR leaves little room to hedge. In most cases, the IDRE selects either the provider's offer or the payor's, in full, with nothing in between. Aim too low and reimbursement the provider was entitled to stays with the payor. Aim too high and the offer loses outright. The entire recovery depends on putting forward an amount the provider can credibly defend with the right evidence.
Making those decisions requires data, and some of it is public. CMS releases the Federal IDR Public Use File (PUF), which reports offer amounts and outcomes for closed determinations. It's a valuable resource, but it's history with the reasoning stripped out.
The public record shows what happened across many disputes, not why. Documentation quality, how the statutory factors were presented, and whether the payor ultimately paid the award all influence outcomes, yet none of that appears in the dataset.
The result is that two disputes can look nearly identical in the PUF and end with opposite determinations, with nothing in the record to explain the difference. Likewise, a dispute can appear to be a win because the provider's offer prevailed, even though the payor never ultimately paid the award.
That missing context has to come from somewhere. The differentiator isn't filing more disputes; it's having enough of them to learn what works and the ability to systematically analyze those insights over time. A provider filing a handful of cases each year learns them slowly, if at all. A high-volume in-house program, or an IDR vendor managing disputes for many providers, learns them much faster.
4. Cash-flow tolerance: “Can we afford the outlay and risk?”
A provider can clear the first three factors and still stall on this one: launching an IDR program requires fronting costs before dollars start coming in.
Every dispute begins with administrative and IDRE fees. Those costs are incurred early in the process, while payments and refunds come back on a lag. Across hundreds or thousands of disputes, that can leave meaningful working capital tied up for months before the program begins funding itself through recoveries.
But winning an arbitration award doesn't eliminate the risk.
Collection is a separate hurdle, and providers have limited recourse when a payor doesn't pay. The United States Court of Appeals for the Fifth Circuit held that the No Surprises Act gives providers no private right of action to sue over an unpaid award and other federal court cases have reached the same conclusion. That makes disciplined claim selection and offer strategy even more critical. The goal is not to file every dispute possible or demand the highest defensible amount, but to pursue claims that are likely to be won and ultimately get paid.
This factor gates the other three. A provider can have the claim volume, build a compliant operation, and make sound arbitration decisions, yet still find the cash requirements and collection risk more than the balance sheet can comfortably absorb.
For organizations in that position, partnering with an IDR vendor can materially change the economics of the program. Some vendors front the process fees, eliminating the need for providers to finance disputes while they work through arbitration. Others go a step further, deferring their contingency fee until the money is in the provider’s lockbox, not when the arbitration award is issued. When cash flow is the limiting factor, these differences in vendor structure can matter just as much as the recovery rate.
Signals your organization should consider an IDR vendor
The four build-versus-buy factors rarely point unanimously in one direction. In practice, a few specific signals tip the decision toward partnering with an IDR vendor. The more of these that describe a provider’s situation, the stronger the case.
The signals can also point the other way. A provider with high recurring eligible out-of-network claim volume, an experienced team already in place, and the capital to fund the program may recover more by keeping IDR in-house and the full margin with it.
How Pivotal works as your IDR vendor
For providers whose evaluation points toward partnering, Pivotal Health offers a technology-driven approach to IDR designed to remove the barriers this framework lays out.
At the center is a purpose-built IDR platform that incorporates years of IDR-specific expertise and automates the entire process: identifying eligible claims, batching them to keep per-dispute fees down, managing deadlines, generating credible offers informed by determination history, and tracking each dispute through payment. The technology is backed by customer success specialists who provide hands-on support throughout. Together, the Pivotal platform and team enable providers to capture the reimbursement they're rightfully owed without standing up and maintaining an IDR operation themselves.
Today, Pivotal supports more than 200 hospital-based physician groups, specialty practices, and health systems, processing more than 200,000 IDR claims each month. That scale keeps expanding our IDR dataset, and each new claim builds more expertise into the platform. The platform itself then drives disciplined, compliant execution and consistently unlocks fair reimbursement for our customers.
And to keep incentives aligned, Pivotal works on contingency and earns its fee only after the provider has collected payment, not when an arbitration award is issued. Because we only get paid when you do, we have every reason to run the process compliantly: submitting eligible claims and making reasonable, well-supported offers. When a payor can see that a dispute was brought in good faith and the ask was fair, they're far more likely to pay it.
