Regulatory Committee Insight: Understanding the ins and outs of the APR-DRG system

The All Patient Refined Diagnosis-Related Group (APR-DRG) system, developed by 3M (now Solventum), is an inpatient classification methodology that groups hospital stays based on clinical similarities, resource use, severity of illness (SOI), and risk of mortality (ROM). It refines earlier DRG systems to better capture patient complexity across all populations, including pediatrics, obstetrics, and non-Medicare cases.
