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 86% of disputes involving self-funded employer plans, virtually all BCBS Arizona claims follow the federal IDR process, because ERISA prevents Arizona from regulating those plans even where state law exists. Fully insured plans account for only 2%, so a state route applies to a negligible share of volume. The individual market adds 7% and FEHB carriers 4%. Disputes with no plan response total 109.
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 BCBS Arizona
- Plan on the federal route for most claims, given the 86% self-funded share, and check federal IDR eligibility criteria first.
- Confirm the plan type from the EOB rather than assuming it, particularly with employer groups of similar size.
- Note the 4% FEHB share and determine whether the claim falls under FEHB rules, which sit outside the standard IDR process.
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×.
