Sydra is an AI-powered platform for the No Surprises Act (NSA) Independent Dispute Resolution (IDR) process. It automates eligibility screening, evidence packaging, offer preparation, submission, and deadline tracking so providers, contingency firms, and RCM companies recover fair out-of-network payments.

Healthcare providers and provider groups, contingency firms pursuing out-of-network disputes, and revenue cycle management (RCM) companies that add NSA IDR to their services.

Do you file disputes for us, or is it self-service?

Both. Sydra offers full-service filing (we file for you), self-service (your team files with the software), or staff training. You can switch models at any time.

How much does Sydra cost?

Sydra is a flat, predictable fee — less than half of what most contingency firms charge (which typically take 20% or more of every recovery, indefinitely) — or you can license the software and run it yourself.

Is Sydra HIPAA compliant?

Yes. Protected health information is handled under a Business Associate Agreement (BAA).

We use privacy-friendly, cookieless analytics (Plausible) plus one first-party cookie for anonymous visit counting — no advertising and no cross-site tracking. See our Cookie Policy and Privacy Policy.

Out-of-network claims in Illinois — that payment is an opening offer

Dispute pathway: Federal IDR + state pathway

Out-of-network surgical and hospital-based claims in Illinois 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 Illinois

Federal IDR + state pathway

Illinois runs binding, baseball-style arbitration for out-of-network payment disputes (215 ILCS 5/356z.3a; Public Act 102-0901, effective 2022). After a 30-day window either party may file; the arbiter picks one final offer and decides within 45 days.

State-regulated plans follow Illinois's arbitration. Self-funded ERISA plans follow the federal IDR process. Confirm routing by plan type before filing.

What's specific to Illinois

Illinois bars treating the insurer's qualifying payment amount as a presumed-correct number — a provider-favorable departure from the federal QPA anchor.
Providers may batch similar claims into a single arbitration.

There is a defined pathway between a payer's underpayment and a binding arbitrated amount — an open negotiation window, an eligibility determination, a batching decision, then arbitration. Each step has a hard deadline, and missing one forfeits the claim. Providers win roughly 88% of federal IDR determinations they contest. Sydra is a flat, predictable fee — less than half of what most contingency firms charge. We file it, you keep the recovery.
