Glossary Definition

Last Updated: 2006-11-02


Part of the Johns Hopkins diagnosis grouping and case-mix tools, this classification tool categorizes ICD-9-CM diagnosis codes found in claims into 190 disease-specific clinical categories (EDCs or Dino-Clusters). These can then be used to identify persons with specific diseases or symptoms without the need to create algorithms. "The 190 EDCs are organized into 27 categories called Major Expanded Diagnosis Clusters (MEDCs)".
