WIESNZ08 cost weights


This document provides the definitions for inclusion of hospital events in casemix funding together with information related to the calculation of cost weights for these events and the assignment of events to purchase units. WIESNZ08 uses the same AR-DRG set as the WIES11C framework, but new cost weights are provided.

This version includes the following major changes:

  • a new cost weight table, based on New Zealand costs;
  • the framework rules now indicate the appropriate non casemix purchase unit (XPU) to apply to casemix-excluded events.

Supplementary changes
