Pillar 1 · The BaseRate™ CompositeHow 1.00× Fair BaseRate Works: Raw price averages unfairly penalize hospitals in high-wage cities or trauma centers treating sicker patients. We adjust for local CMS hospital wage levels and patient complexity first. A 1.00× score means right at the fair price average, 0.85× means 15% cheaper than fair market, and 1.30× means 30% above fair market.Near Fair BaseRate Benchmark
1.00×vs. Fair Market Price
Position vs. 1.00× Fair PriceRight at U.S. Average (0%) 1.00× (center of the bar) is the U.S. fair price average after accounting for local hospital wages and patient complexity. Left of center (<1.00×) is below fair price; right of center (>1.00×) is above fair price.

Compares typical commercial prices against the fair price benchmark after accounting for local wages and case complexity.

Pillar 2 · VeriRate™ Data TrustHow VeriRate™ (0–100) Works: Hospitals are legally required to publish machine-readable price files, but some bury fake $0.01 numbers or omit cash discounts. VeriRate audits each file across 5 checks (hover any badge below to see what it tests).86/100 · Verified

File Completeness90Provenance (File Completeness): Checks whether the hospital published a complete, up-to-date machine-readable price file with valid CPT and MS-DRG billing codes instead of leaving blanks.
Price Logic88Coherence (Price Logic): Checks whether the hospital’s numbers make basic sense — e.g., self-pay cash price is lower than gross list price, with no fake $0.01 or $999,999 placeholder numbers.
Peer Alignment86Concordance (Peer Alignment): Checks whether reported prices sit in a realistic range compared to Medicare and nearby hospitals rather than wild 100× unit errors.
Clean Billing83Regularity (Clean Billing): Checks whether rates are structured consistently across procedures without erratic statistical spikes or hidden unbundled facility fees.
Real Cash Discount84Cash Honesty (Real Cash Discount): Checks whether the hospital offers a genuine self-pay cash discount that beats or matches commercial insurance rates instead of billing full sticker price.
