BODYSYSTEMn - ICD-9-CM Body system n

Documentation Sections:

The Chronic Condition Indicator provides an easy way for users to categorize ICD-9-CM diagnosis codes into one of two categories: chronic or not chronic. 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. The body system indicator is based upon the chapters of the ICD-9-CM codebook. More information on the Chronic Condition Indicators is available under Tools & Software on the HCUP-US website.
