A Diagnosis-Related Group (DRG) is a statistical system of classifying any inpatient stay into groups for the purposes of payment. The DRG classification system divides possible diagnoses into more than 20 major body systems and subdivides them into almost 500 groups for the purpose of Medicare reimbursement.

Ourdata files contain the complete list of 2019 Diagnosis Related Groups (DRGs) with several added features, including:
