Clinical Classifications Software
Developed at the Agency for Healthcare Research and Quality (AHRQ), the Clinical Classifications Software (CCS)
is a tool for clustering patient diagnoses and procedures into a manageable number of clinically meaningful
categories. CCS offers researchers the ability to group conditions and procedures without having to sort
through thousands of codes. This "clinical grouper" makes it easier to quickly understand patterns of
diagnoses and procedures so that health plans, policy makers, and researchers can analyze costs,
utilization, and outcomes associated with particular illnesses and procedures.
CCS collapses diagnosis and procedure codes from the International Classification of Diseases, 9th Revision, Clinical Modification (IDC-9-CM), which contains more than 13,600 diagnosis codes and 3,700 procedure codes. Without the CCS tool, the large number of ICD-9-CM codes makes statistical analysis and reporting difficult and time-consuming. For more information, see AHRQ's CCS Fact Sheet.
The NJSHAD system uses CCS Procedure Groups in the Inpatient Hospital Discharge Query Module.
