1 The category of "Unknown" represents all values that were invalid entries, values recorded as "unknown,"
or when no values were entered for the field.
2 The Center for Medicare & Medicaid Services moved away from diagnosis-related groups (DRGs) to Medicare Severity DRGs (MS-DRGs) effective October 1, 2007. Previously, DRG codes for Delivery were 370-375, for Newborns 385-391, and for Rehabilitation 462.
3As of October 1, 2009, a new ICD-9 code category was added to the Influenza code ('487'). The new code ('488') identifies the influenza virus when known (such as Avian influenza virus and H1N1). This query system has been updated to reflect this change where Cause of Hospitalization="Pneumonia/Influenza" .
4The payor category of "Other" includes Workers Compensation.
