Developed by 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. The Clinical Classifications Software (CCS) for Mortality Reporting is a diagnosis categorization scheme that can be employed in many types of projects analyzing data on diagnoses. This tool is based on the International Classification of Diseases, 10th Revision (ICD-10), a uniform and standardized coding system, which has been used in the U.S. for mortality reporting since 1999. The ICD-10’s multitude of codes, more than 32,000 diagnosis codes in all are collapsed into a smaller number of clinically meaningful categories that are sometimes more useful for presenting descriptive statistics than are individual ICD-10-CM codes.
CCS for Mortality Reporting categories can be employed in many types of projects analyzing data on diagnoses. For example, they can be used to:
– Identify populations for disease-specific studies
– Gain a better understanding of the distribution of certain conditions across disease groupings
– Examine trends in mortality by broad diagnosis groupings
