Same hospital, same procedure — different price depending on who’s paying. Each payer’s median negotiated rate as a percent of Medicare, across every hospital × procedure cell where that payer publishes commercial rates. Spread is the typical same-procedure price ratio between this payer’s cheapest and most expensive hospitals (10th–90th percentile, median across procedures): a low median with a wide spread still overpays somewhere.
