The Issue
Healthcare-payment debates often place unlike dollar constructs side by side: billed charge, contracted rate, Medicare payment, Qualifying Payment Amount (QPA), party offer, agreed amount, and selected IDR payment. They may be related, but they arise from different methods and answer different questions. Calling each one a “rate” or “market value” creates false equivalence.
Why it matters
- The No Surprises Act gives QPA a defined legal role; an out-of-network payment can arise through agreement or IDR.
- Policy analysis becomes unstable when one construct silently borrows the meaning of another.
- Public-use data are valuable only when cohort, version, missingness, selection, and distribution are visible.
Policy Direction
Recommended action: Adopt a Payment Benchmark Transparency and Construct-Separation Standard requiring every public payment metric to identify the construct it measures, its numerator and denominator, cohort, time period, distribution, missingness, and limits—while expressly prohibiting use of the Adjudicated Rate Index as an individual payment formula or substitute for the statutory Qualifying Payment Amount.
- Label every payment construct explicitly and disclose numerator, denominator, unit, cohort, geography, period, exclusions, and data version.
- Report distributions, sample size, subgroup results, correction history, and known missingness—not only a headline multiple.
- Preserve the statutory role of QPA and prohibit use of ARI as an individual payment formula or substitute benchmark.
- Replicate across procedures, specialties, regions, payers, years, and data sources before generalizing.
What the research contributes
ARI is the cohort median of case-level selected-payment-to-reported-QPA multiples. In CMS federal IDR data for complex repair codes (2023 Q1–2025 Q2), the median was 22.41× among analytic cases and 28.73× in provider/facility-prevailing cases; plan-prevailing disputes clustered near QPA parity. The study supports descriptive separation within that domain.
Evidentiary Boundary
ARI does not prove that QPA was wrong, that a selected payment was correct, that either multiple should be paid elsewhere, or that the findings generalize beyond the studied code family and dataset. It does not predict an individual IDR outcome.
