Measuring severity of illness within diagnosis-related groups (DRGs) has become increasingly important because of the growing need to compare outcomes across providers. In response to these needs, the Health Care Financing Administration (HCFA) has developed a DRG-based severity system as a refinement to its current Medicare DRG structure. As a result of this recent HCFA research, all-payer severity-adjusted DRGs (APS-DRGs) have been developed to provide a uniform approach for severity classification that is also applicable to the all-payer population.
