Hospital Price Lens
Hospital Price Lens organizes hospitals' published standard-charge files and explains when those prices can and cannot be compared across hospitals. Hospitals are required to publish their standard charges, but the files are messy and rarely comparable as-is. This site currently covers the Nashville corpus only — more metros are planned.

From published to comparable
Hospitals publish far more price rows than qualify for cross-hospital comparison. Each stage below applies another comparison rule. Rows that do not pass remain in the data but are excluded from rankings.
Hospitals by data confidence
Data confidence describes how usable each hospital's published file is for price comparison. It does not measure care quality or legal compliance.
See the hospital scoreboard for each hospital's score and what it is made of.
Featured price comparisons
Each row shows its comparable-hospital count ("n") — the number of hospitals behind the statistics, each contributing exactly one representative price. Click a service to see every hospital's price for that exact context.
Why many rows can't be compared
A single row can be blocked for several reasons at once, so these counts overlap. The full explanation of every blocker lives on the data quality page.
