Source: CMS, Federal IDR Supplemental Tables, Q3 and Q4 2025, 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
With 63% of disputes involving self-funded employer plans, most claims against UnitedHealthcare fall under ERISA, which prevents states from regulating self-funded plans. For those claims, the federal No Surprises Act IDR process applies even in states with their own surprise-billing laws. Fully insured plans make up 24% of disputes, so a meaningful share of claims may be eligible for a state-route alternative where one exists. State and local government plans add another 9%; those are not ERISA plans, so what applies to them depends on the state. A further 4,308 disputes show no plan response, meaning the plan type was never established.
Why this decides so much: filing into the wrong process ends the dispute on eligibility rather than on the merits. Of the 1,449,900 disputes closed nationally in the second half of 2025, 271,399 — about 19% — were closed as ineligible, and the non-initiating party challenged eligibility in 574,128 of the 1,372,563 disputes initiated. What eligibility turns on.
Before you file against UnitedHealthcare
- Confirm whether the plan is self-funded or fully insured before selecting a route, since 63% of disputes here involve self-funded plans.
- Obtain plan-type documentation early from the EOB or plan documents — 4,308 disputes here were logged with no plan response at all.
- Check federal IDR filing deadlines and required documents for the specific plan type on the EOB.
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 5.22× the plan's own qualifying payment amount on claims under $100, falling to 1.69× at $10,000 and above, and it varies by specialty from 2.00× to 25.85×.
