We file and win No Surprises Act disputes for out-of-network providers
Flat fee per filing. You keep every dollar of the award.
Payers count on out-of-network groups never pushing back. The No Surprises Act gave providers a federal arbitration process, called independent dispute resolution (IDR), and the published record shows providers win it 4 out of 5 times. Lido IDR runs that process for you: eligibility, deadlines, evidence, and filing.
All 3.39 million federal IDR disputes published by CMS, 2023 through 2025. Explore the data at idrexplorer.com.
What is Lido IDR? Lido IDR files No Surprises Act arbitration cases (federal IDR) for out-of-network providers and the billing companies that serve them. We find the eligible claims, track every deadline, prepare the evidence, and submit the filings, for a flat fee per filing instead of a percentage of the award. The service is built by Lido, a software company, on top of every federal IDR decision CMS has published.

The deadlines are the trap
The No Surprises Act runs on business-day clocks: 30 days to open negotiation, 30 days of negotiation, 4 days to start arbitration. Payers know the clocks better than most practices do. Some ask for 45 more days and hope the window closes. For most groups the entire process is a spreadsheet counting down 30 days, and one vacation week away from a missed deadline. We track every clock on every claim, so no dispute dies of old age.
Paid is not the same as paid fairly
Underpaid claims are invisible. A claim billed at $554 and paid at $74.74 never appears in a denial queue, because the payer technically paid it. Groups accept those scraps for years because contesting each one by hand costs more than the difference. Arbitration changes that math: the median federal IDR award runs 4.7 times the qualifying payment amount the payer started from.
You did not sign up to run an arbitration desk
Portal re-keying, evidence packets, offer deadlines, fee receipts. Groups that file at volume do most of it by hand, and practice leaders tell us plainly they do not want to be in the arbitration business. That is the part we take off your desk. You approve the strategy, we do the filing work.
How it works
One pipeline carries every claim from remittance to award. Software does the repetitive parts: reading remits, checking eligibility, tracking business day clocks, assembling filings. Anything that needs judgment leaves the lane and goes to a person, with the reason attached. No offer goes out without your approval.
Swipe to see the full pipeline
- We find the eligible claims. From your remits, we flag which out-of-network claims qualify under the No Surprises Act and what similar claims have won in your state and specialty.
- We prepare and file everything on time. Open negotiation notices, IDR initiation, offers, evidence packets, each inside its deadline. You see the status of every dispute.
- You keep the award. Payers pay your group directly. Our flat fee per filing is the same whether the award is $500 or $50,000, so our incentive is simple: file everything worth filing, and win it.
Built on the public record, by a software company
Lido IDR is built by Lido, the document automation company. We started by publishing the entire federal IDR record at idrexplorer.com: every dispute, every payer, every IDR entity, and award benchmarks for more than 800 specialty and state combinations. That data now powers our filings, from picking winnable claims to setting offer amounts. More about us.
Common questions
What does Lido IDR cost?
A flat fee per filing, quoted for your claim volume on a 30 minute call. We never take a percentage of your awards. Separately, CMS charges each party a $15 administrative fee per dispute, and the certified IDR entity charges a fee that is refunded to you when you win. Full fee breakdown.
Who can use federal IDR under the No Surprises Act?
Out-of-network providers, for emergency services, for non-emergency services at in-network facilities such as hospitals and surgery centers, and for air ambulance transport. In states with their own surprise billing process, claims under state-regulated plans go through that process instead. State or federal, explained.
Do you take a percentage of awards?
No. Awards are paid by the payer directly to your group, and you keep all of them. Most IDR vendors and law firms take roughly 15 to 35 percent of each award instead. What that costs on your award sizes.
How often do providers win?
Providers won 85.8% of decided federal IDR disputes from 2023 through 2025, with a median award of 4.7 times the qualifying payment amount and a median of 37 days from filing to decision. Computed from the CMS federal IDR public use files at the dispute level.
