Source: CMS, Federal IDR Supplemental Tables, Q3 and Q4 2024, Table 9 — “Top 10 Non-Initiating Parties”. “Non-initiating party” is the Departments' own term for the party a dispute is brought against; it carries no finding about conduct, and the counts measure volume of disputes rather than anything else. CMS publishes these tables here.
Federal Process or State Process
Because ERISA preempts state regulation of self-insured employer plans, the federal IDR route applies to the 74% of disputes tied to self-insured coverage regardless of any state surprise-billing law. The 20% fully insured share is the only portion where a state pathway may be available, depending on the state; the individual market, FEHB, and unidentified plans follow their respective applicable pathways.
Why this decides so much: filing into the wrong process ends the dispute on eligibility rather than on the merits. About 19% of disputes initiated nationally in 2024 were found ineligible, and eligibility was challenged by the other side in 41% to 43% of disputes in the second half of that year. What eligibility turns on.
Before you file against UnitedHealthcare
- Confirm the plan's funding type from the SPD before choosing the federal or state route, since 74% of the profile is self-insured
- Verify the 30-day open-negotiation and 4-day IDR initiation deadlines against the date of the payment or denial
- For the 12,593 disputes logged without a plan response, compile the eligibility file and remittance advice to establish the funding type
What the Federal Medians Say Your Claims Are Worth
Volume tells you who is in the room. What a decided dispute is worth depends on the service and the size of the claim, not on the payer: CMS reports the median prevailing offer at 5.53× the plan's own qualifying payment amount on claims under $100, falling to 1.73× at $10,000 and above, and it varies by specialty from 2.26× to 16.75×.
