Answers / What a filing service does

What does an IDR filing service do?

Federal IDR is not a courtroom process. There is no hearing, no testimony, and no judge. Each side submits one payment offer with written evidence, and a certified IDR entity picks one offer in full. That design is why a filing service can run the process at scale, and why the quality of the service shows up in operational details: which claims it finds, what it files on time, and what its evidence packets say. Providers win 85.8 percent of federal IDR disputes that reach a decision, the median award is 4.7 times the qualifying payment amount, and the median time from filing to decision is 37 days, based on 3.39 million disputes in the federal public use files.

Stage one: eligibility screening

Everything starts with the remittance data. The service reads your payer remits and flags claims that qualify under the No Surprises Act: out-of-network emergency services, out-of-network care at an in-network facility, and air ambulance transport. It also sorts each claim onto the right track. Self-funded employer plans go through the federal process, while fully insured plans in some states follow a state arbitration process instead. The sorting matters because the deadlines and rules differ by track. The full rules are in who can use federal IDR.

Screening is also where underpayments get found. An underpaid out-of-network claim does not land in a denial queue, because the payer technically paid it. The explanation of benefits says processed and the balance quietly disappears. A filing service compares what the payer paid against benchmarks for the same service in your state and specialty, and flags the gap.

Stage two: open negotiation

Before any dispute can be filed, the No Surprises Act requires open negotiation. The provider must send the open negotiation notice within 30 business days of the payer's initial payment or denial, and the negotiation window then runs 30 business days. The service sends the notice, tracks the window, and negotiates. A meaningful share of claims settle here, which is cheaper and faster than arbitration for everyone. A service that treats open negotiation as a formality is leaving the fastest money on the table.

Stage three: filing in the federal portal

If negotiation fails, the window to act is short: 4 business days to initiate the dispute in the federal IDR portal. The service prepares the initiation, handles the certified IDR entity selection, and responds to eligibility challenges from the payer. This stage is also where batching happens. Claims against the same payer for the same or similar services, furnished within a 30 business day window, can be combined into a single dispute. Batching spreads the fixed fees across more claims and is the single biggest lever on the economics of small-dollar claims.

Stage four: the offer and the evidence packet

Each party submits one offer, and the arbiter must choose one of the two. There is no splitting the difference. That rule makes offer strategy a real discipline: the offer has to be aggressive enough to be worth filing and credible enough to be chosen over the payer's. The evidence packet is the argument for it, built around the qualifying payment amount the payer disclosed, the complexity of the case, the provider's training and outcomes, and what arbiters have awarded for comparable services. A filing service that works from published decision data, like the record at idrexplorer.com, can set offers from evidence instead of instinct.

Stage five: fees

Two government-side fees attach to every dispute. Each party pays a $15 administrative fee per dispute, set by the May 2026 rule for disputes initiated on or after June 11, 2026. Each party also deposits the certified IDR entity fee, and the winner gets that deposit refunded, so the losing party ultimately pays it. The service pays these on time, tracks the refunds, and accounts for them in what it recommends filing. The pricing details, including what the service itself charges, are in IDR filing service pricing.

Stage six: decision and payment

The median time from filing to decision is 37 days. The decision is binding. The payer must pay the awarded amount within 30 calendar days, and this is where a surprising amount of revenue stalls: awards that simply do not get paid. The service tracks every award to payment, documents non-payment, and files complaints with CMS when payers sit on binding awards.

Stage seven: reporting

The process produces data your group should own: which payers underpay, which services win, award sizes against the qualifying payment amount, and where revenue is leaking. A good service reports per-dispute outcomes, not just a quarterly total. That reporting is also how you audit the service itself.

What a filing service does not do

Two things sit outside the job. It does not litigate: if a payer ignores a binding award, the service documents the non-payment, files the CMS complaint, and hands the record to your attorney. And it does not negotiate network contracts: IDR is for out-of-network claims, and joining a network is a separate decision the data can inform but the service does not make.

How services charge for all this

Two models. Contingency firms take 15 to 25 percent of the recovery, the dollars collected above the payer's initial payment. Flat fee services charge a fixed amount per arbitration. Lido IDR uses the flat fee model: no percentage of the award, every dollar of the award is yours.
