*In October 2007, the DRG system was drastically changed by the federal government and is now known as the MS-DRG system. [MS-DRG = Medicare Severity Diagnosis Related Groups]. Assignment to one of the new MS-DRGs is intended to be more closely associated with the severity of the patient’s condition. There is no one-to-one crosswalk from the DRG system to the new MS-DRG system. Please see the MS-DRG_ID file for the new definitions.
**The groupings for payers have changed from those in prior years due to the adoption of the UB-04 billing form in place of the UB-92 in October 2007. Please see the PAYER1_ID_2011 file for the current year's codes. Note: Beginning in 2011, there were 60 diagnosis codes, which included 1 principal diagnosis code and 59 secondary codes. Prior to 2011, there were only 18 diagnosis codes.
