**“x Medicare”** compares each price with what original Medicare actually paid hospitals in the same state for the same kind of stay in 2024, the newest year it has published: the average per stay, the patient’s share included, at hospitals with more than ten such stays. Medicare’s payment varies by hospital (wages, teaching, low-income patients), so this is a state average, not any one hospital’s rate. Insurers write their contracts as a share of Medicare, so 1.3x means the insurer pays 30% more than Medicare would; Medicare Advantage plans generally pay close to 1.0x.

Prices are what the insurer has agreed to pay, not what you will be billed. This is a statewide summary: prices vary far more between towns and between practices than these medians suggest, and "providers" counts everyone with a contracted price, not only those who perform the procedure.
