About Sydra
Built by a surgeon who ran the workflow.Not a technology company that discovered healthcare.
Sydra is federal IDR software built out of a working revenue cycle operation, founded by Dr. John M. Abrahams, MD, a board certified practicing neurosurgeon in New York.
The team
Dr. John M. Abrahams, MD
Founder, Board Certified Neurosurgeon
Fellow, American Association of Neurological Surgeons · President, New York Brain & Spine Surgery · Founder, Sydra
Dr. John M. Abrahams, MD is a practicing neurosurgeon in New York. He built the original federal IDR submission process for his own neurosurgical practice after the No Surprises Act took effect in 2022, and it produced consistently better outcomes than the contingency model the practice had used before.
The clinical coding framework, the determination library curation criteria, and the clinical necessity narrative structure in Sydra are all built from that work. He reviews every piece of medical content Sydra publishes.

Why this origin matters for your practice.
Most software in this category is built by people who read the regulation. This was built by someone who missed deadlines, argued market rate, and watched a contingency take 20 percent of recoveries he had already done the clinical work for.
That is why Sydra defaults to one claim per CPT, why the eligibility check runs before drafting, and why nothing files without a human approving it. Those are not product decisions made in a planning session. They are scar tissue.
