Updated releases of HCUP Comorbidity Software and Clinical Classifications Software Updates are available

The Agency for Healthcare Research and Quality (AHRQ) recently released the Comorbidity Software, Version 3.3, and fiscal year 2008 updates for the Clinical Classifications Software (CCS) for Services and Procedures for use with databases available from the Agency's Healthcare Cost and Utilization Project (HCUP) or other health care administrative databases.

The Comorbidity Software, Version 3.3 is valid for ICD-9-CM codes, DRGs, and v25 MS-DRGs effective October 1, 2007. The software is being distributed in ASCII for easy adaptation to other programming languages, such as SAS, SPSS, and Stata. The CCS for Services and Procedures software provides a method for classifying Current Procedural Terminology (CPT) codes and Healthcare Common Procedure Coding System (HCPCS) codes into clinically meaningful procedure categories. It contains the standard CCS procedure categories, with the addition of specific categories unique to the professional service and supply codes in CPT/HCPCS.

Both software updates are available for download from the HCUP-US Web site at
