Policy Statement: In 6.5.2.1c, replace: "This calculation can be summarized as /N where N = P-(X+Y) and P is the organization?s Provider Allocation Unit X is a multiple of 4 greater than 4/3*serving sites and Y is a multiple of 4 greater than 4/3*end sites served by largest serving site." with: "This calculation can be summarized as /N where N = P-(X+Y) and P is the organization?s Provider Allocation Unit, X is a multiple of 4 greater than 4/3*log_2(serving sites) and Y is a multiple of 4 greater than 4/3*log_2(end sites served by largest serving site). In 2.15 and 2.16, replace "provider assignment unit" with "provider allocation unit." Comments: ?Provider assignment unit? in section 2.15 was intended to match ?Provider Allocation Unit? in this policy section, but the words fell out of sync. Timetable for implementation: Immediate
