What Are GPCIs?

The Geographic Practice Cost Index (GPCI) is a set of three adjustment factors used by CMS to modify Medicare physician payments based on geographic differences in the cost of practicing medicine. Every Medicare locality has its own set of GPCI values.

Work GPCI

Adjusts the work RVU based on local physician earnings. Most states have a floor of 1.000.

PE GPCI

Adjusts the practice expense RVU based on local rents, wages, equipment, and supply costs.

MP GPCI

Adjusts the malpractice RVU based on local professional liability insurance premiums.

About Washington: Seattle-area practice expenses are above the national average.

Medicare Payment Formula

CMS calculates Medicare physician payment using this formula:

Payment = [(Work RVU x Work GPCI) + (PE RVU x PE GPCI) + (MP RVU x MP GPCI)] x Conversion Factor

The 2026 Medicare conversion factor is $32.74. This single dollar amount is multiplied by the GPCI-adjusted total RVU to determine the Medicare Allowed Amount for each service.
