General Notes
 

The All Patient Refined DRGs (APR-DRGs) are assigned using software developed by 3M Health Information Systems. This severity measure includes the base APR-DRG, the severity of illness subclass, and the risk of mortality subclass within each base APR-DRG. The prefix "APRDRG" has been included in the data element names to distinguish APR-DRG measures from other HCUP data elements. For more information, please refer to the following documents:

The version of the APR-DRG software varies by data year, but the APR-DRG data elements are uniformly coded across States because they are assigned during HCUP processing.
