How to read “% of Medicare” Medicare’s payment is a hospital-specific benchmark built from CMS files — adjusted for local wages and case complexity, and roughly pegged to the cost of care. A commercial rate at 300% means a private plan pays about triple that benchmark for the same care at the same hospital. The gap is negotiation, not quality. Full methodology →

The gap is $5,277 in every row. The only thing that changes is how much of it reaches the person choosing. Nobody hid the price — the deductible structure hides the difference, and a difference nobody feels is a difference nobody shops. Illustration uses a 20% coinsurance plan with no separate facility or professional bill; your own plan governs.

*Cost estimates use hospital-level cost-to-charge ratios from federal cost reports and are approximate; ~ marks categories (imaging, labs) where they are least precise. "Plan rows" is how many distinct plan rates the hospital published; medians over more rows are sturdier.
