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.

The gap is $13,350 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.
Detail (click headers to sort, or “why” for cost vs price)
*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.
