Filing checklist before you take CPT 84443 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 CPT 84443 median provider-won award is 3.7x QPA across 3,627 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.
