Sydra

For surgical practices fighting insurance underpayments

Win more IDR disputes.
In minutes, not hours.

Sydra drafts your No Surprises Act IDR submissions using AI trained on hundreds of real determinations — built by a practicing neurosurgeon who got tired of insurance companies underpaying his cases.

No setup fees. Integrates with your EMR and Clearinghouse. SOC 2 controls in place.

Insurers are systematically underpaying out-of-network claims.

The No Surprises Act gave providers the right to dispute these payments through Independent Dispute Resolution — but writing a winning IDR submission takes hours of clinical, financial, and legal work for every case. Most practices either skip it or pay a billing service 30%+ of recovered revenue.

Sydra changes that math.

What Sydra produces

  • Executive summary tailored to your CPT codes
  • Market-rate justification with comparable cases
  • Citations from prior winning determinations
  • Clinical-necessity narrative drawn from your op notes
  • Submission-ready DOCX export with checklist

How it works

Three steps from claim to submission

1

Upload your case

Drop in EOBs, op notes, patient notes, radiology, or scan a denial letter. Sydra pulls structured data automatically — CPT codes, dates, charges, patient demographics — and matches it against your provider profile.

2

Sydra drafts the submission

Our AI — trained on hundreds of real IDR determinations — identifies the strongest argument for your specific CPT codes, cites prior wins, and assembles the executive summary, market-rate analysis, and clinical narrative.

3

Review, export, submit

You review the draft and edit anything you want. One click to copy for the IDRE portal or export as a submission-ready DOCX with a guided checklist. Clearinghouse and EMR integration handles the upstream data flow.

Why it works

The library is the moat

We've ingested every public IDR determination relevant to surgical practices. Sydra knows what arguments actually win — and what patterns the IDREs reject.

About Sydra

Built by a surgeon, not a billing company.

Sydra is a product of Kronos Health, an expert in Revenue Cycle Management and specifically the NSA IDR Process.

After watching insurers underpay his own cases case after case, and seeing the legal-hourly-rate billing companies charge to handle IDR submissions, he built Sydra for his practice and then opened it to other surgical groups.

Sydra runs in production today at NY Brain & Spine Surgery and is being licensed to additional surgical practices in 2026.

Common questions

What does Sydra cost?

Sydra is licensed per-practice with annual pricing scaled to your submission volume. Most practices recover the license cost on their first 1–2 cases. Request a demo for a custom quote.

How long does setup take?

Most practices are up and running in under a week. We provision your tenant, import your provider profiles, connect your clearinghouse and EMR, and walk one of your billing leads through their first submission.

Is my data secure?

Yes. Strict tenant isolation, encrypted at rest and in transit, AWS BAA in place, role-based access for your staff. PHI is handled under HIPAA controls. We are happy to walk through our security posture with your compliance team before signing.

Does Sydra replace my biller?

No. Sydra is the IDR layer specifically. Your biller still handles charge capture, claim submission, and standard A/R follow-up. When a denial qualifies for IDR, Sydra is the tool that drafts the submission faster and stronger than a biller can on their own.
