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.
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.
Pick a measure. Click a state to see its hospitals and surgery centers, then a hospital for its full record.

Every hospital is a row. Choose a question or build your own: any two measures, grouped any way, with the statistics computed live.
Ask in plain English. Claude writes one read-only query against the atlas, your browser runs it, and you see the answer with the query and its assumptions. Public questions join the wall.
Every number traces to a public file. Here is where each comes from and what it can't tell you.
