General Notes

The All Patient Refined Risk of Mortality Class (ADRGRiskMortality) reports the likelihood of dying as determined by the APR system. APR Risk of Mortality Class is supplied by the data source. During HCUP processing, the codes are assigned to the HCUP data element ADRGRMS as reported, without modification. For more information see "All Patient Refined Diagnosis Related Groups (APR-DRGs)," published by 3M Health Information Services. In HCUP databases before 1998, this data element is called ADRGRMS.
