A public record, finally readable.
When an insurer and a provider can't agree on an out-of-network bill under the No Surprises Act, the fight goes to arbitration — and the outcome becomes part of the public record. That record is vast, scattered, and almost nobody reads it. NSA Tracker turns it into something you can actually look at — who files, who wins, who arbitrates, and where each insurer sets its benchmark.

Where the numbers come from
NSA Tracker is built entirely on public, fair-use records — synthesized and aggregated from several public sources, including government releases, Freedom of Information Act files, and CMS public data covering out-of-network payment disputes under the No Surprises Act. Every figure on this site is counted or derived from those public records. There is no private data, no third-party feed, and no login.

Read the walkthrough →Methodology
A counted figure is never blurred with a modelled one — what's exact is shown exact, what's estimated is labeled, and what the record can't support is left out.
Read the method →Absent is not zero. A state the record never covered is drawn as stippled, not colored pale — and a quarter that does not exist is a hole in the timeline that playback steps over, never through.
