Same operation · Three buildings · Every hospital

One knee. Three prices.

What Medicare pays for a joint replacement at a surgery center, a hospital outpatient department, and a hospital inpatient unit, for every hospital that reports it. Add quality, list prices, and the surgery centers down the road.

Why this exists

Prices you can see are prices you can question.

American health care pays very different amounts for the same operation, depending on the building it happens in. Most of that is invisible to the people who choose where to have surgery.

This atlas puts the public record in one place: what Medicare pays every hospital, what hospitals list, how they perform, and which surgery centers are close by. It is free, and every number traces to a federal file.
