Source & method

Show sources

This page uses CMS's Medicare Physician Fee Schedule Q1 2017 release (effective January 2017). National baselines use GPCI 1.000 and exclude sequestration. Whether a national amount exists depends on the status and CMS’s payment instructions; blank RVUs are never treated as zero. Past releases are never edited, so these sources stay valid after CMS publishes a newer one. Our methodology explains sourcing, parsing, versioning, and how we cross-check claims before we publish them.
