Why hospital bills get a dedicated analyzer
The evidence audit behind Bill X-Ray. What billing-error research actually supports, where estimates disagree, and how conservative claims discipline shaped the product — including which popular statistics were deliberately dropped.
- Claim discipline: the broad “75–90% of bills contain errors” figure was dropped — it traces largely to interested parties. Public framing: published estimates vary substantially because studies measure different populations, billing stages, and definitions of error.
- $88B medical debt is treated as a dated CFPB (2022) estimate of medical tradelines on credit reports — later bureau analysis (~$49B after record removals) is cited alongside it, never the headline number alone.
- “Under 1% appeal” statistics are scoped to their actual populations — marketplace qualified health plans (KFF, 2024–25) and Medicare Advantage (HHS OIG, 2015) — and never generalized to all insured patients.
- Federal rules cited in-product — FDCPA §1692g, No Surprises Act (PHSA §2799B), IRS §501(r), ERISA §1133, PHSA §2719 — all retrieved 2026-09-25, linked not reproduced.
