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.
convex. adj. 1. curving or bulging outwards. 2. (General Physics) physics having one or two surfaces curved or ground in the shape of a section of the exterior of a sphere, paraboloid, ellipsoid, etc: a convex lens. 3. (Mathematics) maths (of a polygon) containing no interior angle greater than 180Â°.
When all angles are equal and all sides are equal it is regular, otherwise it is irregular: A convex hexagon has no angles pointing inwards. More precisely, no internal angles can be more than 180Â°. When any internal angle is greater than 180Â° it is concave. (Think: concave has a cave in it)
