Source & method
GPCIs and example rates computed from the CMS Medicare Physician Fee Schedule Q3 2026 release. Example amounts are national non-facility figures rescaled by each locality's GPCIs, before the ~2% sequestration cut. Releases are immutable; a rate retrieved for a past quarter always reflects that release.
