Each PHP revenue code is associated with particular cost centers on the cost report. The revenue-to-cost-center crosswalk identifies the primary, secondary (if any), and tertiary (if any) cost centers that are associated with each PHP revenue code, and which are the source for the CCRs used in PHP ratesetting. The PHP portion of that OPPS crosswalk is shown in Table 52 below.
