File Layout Record level data can be provided as a SAS datafile or CSVfile. Two different versions depending onyear: Data years 1995 to 2006 uses UB-92 2007 to current usesUB-04
Diagnosis Code Changes HDDS data years 1995 to September 2015 uses ICD-9-CM codingformat. As of October 1, 2015, all patient data changed to the ICD- 10-CM codingformat.
