Out-of-network claims in Washington — that payment is an opening offer
Dispute pathway: Federal IDR + state pathway
Out-of-network surgical and hospital-based claims in Washington are routinely paid below the billed charge or denied outright. Under the No Surprises Act that payment is an opening offer, and dispute resolution exists to contest it. Sydra checks what qualifies, assembles the submission, holds every deadline, and can file it for you.
How disputes route in Washington
Federal IDR + state pathway
Washington runs baseball-style arbitration for out-of-network payment disputes through the Office of the Insurance Commissioner (Balance Billing Protection Act, 2019; RCW 48.49; WAC 284-43B). The law lets the Commissioner move these disputes to federal IDR, but no transition has taken place: in March 2026 the OIC delayed it for at least two more years, so the state forum remains live.
State-regulated plans follow Washington's arbitration, and self-funded plans may opt in. No move to federal IDR has happened: the Insurance Commissioner has delayed it again and will revisit in 2028. Air ambulance, and self-funded plans that have not opted in, follow the federal IDR process.
What's specific to Washington
- Final-offer arbitration: the arbitrator must award one side's final offer, argued against a commercially reasonable amount referenced to in-network rates. Up to 20 similar claims can be bundled per filing.
- Negotiation runs 30 calendar days from the provider's (deemed) receipt of the carrier's offer to pay, and the arbitration request is due 10 calendar days after negotiation ends.
- Ground ambulance is paid at a set rate with no arbitration, and air ambulance is outside the state process.
Claims that go to federal IDR follow a defined pathway between a payer's underpayment and a binding payment determination — an open negotiation window, an eligibility determination, a batching decision, then a decision by a certified IDR entity. Claims under Washington's own law follow the state rules described above instead. Each step has its own deadline, and missing one can cost the claim. Providers win roughly 88% of federal IDR determinations they contest. Sydra is a capped, predictable fee — less than half of what most contingency firms charge. We file it, you keep the recovery.
