The figures referenced on this site are industry-reported statistics, not Verity findings. Each claim and its basis:
Reported range across industry billing-audit reviews; commonly cited estimates run from 49% to 80% depending on the review and bill type, which is why the site states the figure as “up to.”
KFF (Kaiser Family Foundation) analyses of ACA marketplace (HealthCare.gov) claims data on in-network claim denial rates and consumer appeal rates.
Industry claim-review reporting on audited hospital bills over $10,000, as cited by consumer billing-advocacy organizations.
Figures describe industry-wide patterns and do not predict the outcome of any individual bill or dispute. Verity's own results are reported only when they are real.
