Code of Federal Regulations Title 20. Employees' Benefits § 20.725.710 How are payments for outpatient medical services determined?

(a)(1) Except as provided in paragraphs (b) and (c) of this section, OWCP pays for outpatient medical services according to Ambulatory Payment Classifications (APCs) derived from the Outpatient Prospective Payment System (OPPS) devised by the Centers for Medicare & Medicaid Services (CMS) for the Medicare program (42 CFR part 419).

(2) For outpatient medical services paid under the OPPS, such services are assigned according to the APC prescribed by CMS for that service. Each payment is derived by multiplying the prospectively established scaled relative weight for the service's clinical APC by a conversion factor to arrive at a national unadjusted payment rate for the APC. The labor portion of the national unadjusted payment rate is further adjusted by the hospital wage index for the area where payment is being made. Additional adjustments are also made as required or needed.
