Illustration 1 — Spine surgery group, Texas

From batched attorney filings to 84% win rate in one quarter

A three surgeon spine surgery group was filing NSA IDR through a contingency attorney at 20%. The attorney bundled CPT 22612 with instrumentation add-ons 22840 and 22842 and decompression 63030 into single IDR submissions. Kronos Revenue filed CPT 22612, 22840, 22842, and 63030 as four separate IDR submissions. Win rate on the same claim population, first full quarter under Kronos: 84%. Practice specific dollar figures available under NDA on request.

Illustration 2 — Orthopedic hand surgery, New York

From zero IDR filings to consistent wins

A hand surgery practice was filing zero IDR disputes. 30 plus minutes per claim, 8 to 10 out of network cases per month, accepted insurer initial payment on everything. Kronos handled IDR end to end. First full quarter: provider prevailed in 6 of 7 month one, 6 of 7 month two, 7 of 7 month three. The procedures did not change. The filing did. Practice specific dollar figures available under NDA on request.

Illustration 3 — Neurosurgery, multi practice group

Cranial cases from below average to 91% win rate

A five provider neurosurgery group was using a contingency attorney. Complex cranial cases CPT 61510, 61512, 61520 were filed with generic market rate language. Kronos Revenue took over with procedure specific clinical narrative, surgeon credential block, and prior winning determinations from Sydra library. Win rate on cranial submissions, first two quarters: 91%.

Questions about NSA IDR results

What happens if a claim loses at IDR?
We review the determination, advise on appeal options where available, and factor outcomes into your quarterly recovery review.
Can a claim be re filed?
In some cases yes, depending on the determination basis and statutory windows. We advise case by case.
What is your typical win rate?
We publish recovery rates on our Results page. Exact figures are confirmed during your free case review using your claim data.
How is Kronos different from batched attorney filing?
We file one claim per CPT code — the way federal IDR was designed. Batched filings are the most common reason generalist firms lose.
