What Cardiology teams should benchmark
Cardiology IDR outcomes are shaped by code mix. The same payer can look fair in one lane and misaligned in another. Start with the codes that dominate your disputed claims, then compare state and payer behavior.
The purpose of this page is to help a specialty leader or RCM team decide where the federal IDR data supports a closer claim-level review.

Filing checklist before you take Cardiology claims to IDR
- Confirm the claim is NSA-eligible: emergency care, or out-of-network care at an in-network facility, with no state arbitration law that displaces the federal process for that plan type.
- Start open negotiation within 30 business days of the initial payment or denial notice. The negotiation window then runs 30 business days.
- If negotiation fails, initiate federal IDR through the portal within 4 business days after the window closes.
- Batch same-payer items in the same service code category. Open negotiation periods starting on or after November 1, 2026 can batch up to 50 line items per dispute, up from 25.
- Budget for fees: the federal administrative fee is $15 per party for disputes initiated on or after June 11, 2026 (down from $115), and the non-prevailing party pays the certified IDR entity fee.
- Anchor your offer to the data: the Cardiology median provider-won award is 6.9x QPA across 108,746 disputes.
The fee and batching changes come from the May 2026 federal IDR operations final rule. See the 2026 and 2027 No Surprises Act changes guide for the full timeline, or request a free NSA audit to see how your claims compare.

FAQ
How many Cardiology federal IDR disputes are in the dataset?
This benchmark shows 108,746 Cardiology disputes.
What is the Cardiology provider win rate?
The non-default provider win rate is 85.4%.
What should Cardiology groups compare first?
Start with service-code mix, then narrow by payer and state. That sequence usually gives a more useful answer than a national specialty average.
What changes in 2026 and 2027 affect Cardiology IDR filings?
The administrative fee dropped to $15 per party for disputes initiated on or after June 11, 2026, batching expands to 50 line items for open negotiation periods starting on or after November 1, 2026, and standardized CARC/RARC remittance codes arrive January 1, 2027.
