AHRQ - Chronic Condition Indicator

The Chronic Condition Indicator is one in a family of databases and software tools developed as part of the Healthcare Cost and Utilization Project (HCUP), it provides an easy way for users to categorize ICD-9-CM diagnosis codes as either "chronic" or "not chronic."

The Chronic Condition Indicator is created to facilitate health services research on diagnoses using administrative data. This classification system allows researchers to readily determine if a diagnosis is a chronic condition. In addition, the tool groups all diagnoses into body systems so that users can create indicators listing which specific body systems are affected by a chronic condition.
