Short Info: AR-DRG (Australia)

The ARDRG system was created in 1998 as an original Australian product based on the experience previously gathered from the DRG-inspired system called "AN-DRG".1 In its version 4.1 from 1999, it consisted of 409 base ARDRGs and 661 ARDRGs

[Table 2] A particular feature of the ARDRG system is the CCL matrix (CCL = Complication and Comorbidity Level). In a space-saving way, it allows for each secondary diagnosis to be split into different severity levels depending on the base ARDRG.

[Table 3] Out of the combination of the CCL values of all secondary diagnoses, the "Patient Clinical Complexity Level" (PCCL) is determined. In order to operate with the least number of ARDRGs, PCCLs are subsequently aggregated into one up to four severity categories per base ARDRG.2
