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. Note that MultiPlan is a cost-management and repricing vendor that appears in disputes as the plan's representative, not as the insurer. CMS publishes these tables here.
Federal Process or State Process
ERISA preemption directs the 70% self-insured portion to the federal IDR route. The 5% fully insured share is where a state pathway may be available; the 2% individual market and 0% FEHB follow their 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 MultiPlan
- Verify whether MultiPlan is acting as a leasing network or as the actual plan administrator, since the funding type of the underlying plan determines the route
- Confirm the 30-day open-negotiation and 4-day IDR initiation deadlines against the date of the underlying remittance
- For the 22,720 disputes logged without a plan response, compile the eligibility and contract file to support the funding determination
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×.
