Medicare reference data
See which CMS files support the Medicare reference lookup, the dates covered and the limits of the calculation.
The Medicare reference lookup uses an imported CMS Physician Fee Schedule snapshot. Open the data page to check the service dates, supported settings and source files before using a reference in a comparison.
What the lookup supports
Review the RVU, locality and ZIP sources, along with the conditions where the tool cannot return an amount.

Check the version used for a result. Earlier calculations keep their original source reference when a new version is added.

Each supported lookup identifies the source rows and shows the RVU/GPCI calculation. The optional contract percentage is a separate multiplication. A reference amount does not determine coverage or the final payer payment.
