Payment for a procedure, service or device identified by a HCPCS/CPT code shall not exceed the amount derived by multiplying the Relative Value Units (RVU) values for that procedure by the Geographic Practice Cost Index (GPCI) values for services in that area and by the conversion factor to arrive at a dollar amount assigned to one unit in that category of service.

(a) The “locality” which serves as a basis for the determination of cost is defined by the Office of Management and Budget Metropolitan Statistical Areas. The Director shall base the determination of the relative per capita cost of medical care in a locality using information about enrollment and medical cost per county, provided by the Centers for Medicare and Medicaid Services (CMS).

(b) The Director shall assign the RVUs published by CMS to all services for which CMS has made assignments, using the most recent revision. Where there are no RVUs assigned to a procedure, the Director may develop and assign any RVUs that he or she considers appropriate. The geographic adjustment factor shall be that designated by GPCI for Metropolitan Statistical Areas as devised for CMS and as updated or revised by CMS from time to time. The Director will devise conversion factors for each category of service as appropriate using OWCP's processing experience and internal data.

(c) For example, if the RVUs for a particular surgical procedure are 2.48 for physician's work (W), 3.63 for practice expense (PE), and 0.48 for malpractice insurance (MP), and the conversion factor assigned to one unit in that category of service (surgery) is $61.20, then the maximum allowable charge for one performance of that procedure is the product of the three RVUs times the corresponding GPCI values for the locality times the conversion factor. If the GPCI values for the locality are 0.988(W), 0.948 (PE), and 1.174 (MP), then the maximum payment calculation is:

[(2.48)(0.988) + (3.63)(0.948) + (0.48)(1.174)] × $61.20

[2.45 + 3.44 + .56] × $61.20

6.45 × $61.20 = $394.74
