Section 725.708 - How are payments for professional medical services and medical equipment determined?(a)(1) OWCP pays for professional medical services based on a fee schedule derived from the schedule maintained by the Centers for Medicare & Medicaid Services (CMS) for the payment of such services under the Medicare program ( 42 CFR part 414 ). The schedule OWCP utilizes consists of: An assignment of Relative Value Units (RVU) to procedures identified by Healthcare Common Procedure Coding System/Current Procedural Terminology (HCPCS/CPT) code, which represents the work (relative time and intensity of the service), the practice expense and the malpractice expense, as compared to other procedures of the same general class; an assignment of Geographic Practice Cost Index (GPCI) values, which represent the relative work, practice expense and malpractice expense relative to other localities throughout the country; and a monetary value assignment (conversion factor) for one unit of value for each coded service.(2) The maximum payment for professional medical services identified by a HCPCS/CPT code is calculated by multiplying the RVU values for the service by the GPCI values for such service in that area and multiplying the sum of these values by the conversion factor to arrive at a dollar amount assigned to one unit in that category of service.(3) OWCP utilizes the RVUs published, and updated or revised from time to time, by CMS for all services for which CMS has made assignments. Where there are no RVUs assigned, OWCP may develop and assign any RVUs that OWCP considers appropriate. OWCP utilizes the GPCI for the locality as defined by CMS and as updated or revised by CMS from time to time. OWCP will devise conversion factors for professional medical services using OWCP's processing experience and internal data.(b) Where a professional medical service is not covered by the fee schedule described in paragraph (a) of this section, OWCP may pay for the service based on other fee schedules or pricing formulas utilized by OWCP for professional medical services.(c) Paragraphs (a) and (b) of this section apply to professional medical services rendered after April 26, 2020.(d) OWCP pays for medical equipment identified by a HCPCS/CPT code based on fee schedules or other pricing formulas utilized by OWCP for such equipment.83 FR 27695, June 14, 2018, as amended at 84 FR 64198, Nov. 21, 2019
