All Patient Refined Diagnosis Related Group

Acronym: APR-DRG

All Patient Refined Diagnosis Related Group (APR-DRG) comes from the Diagnosis Related Group (DRG) classification system, which provides a means of relating the type of patients a hospital treats to the costs incurred by the hospital. APR-DRGs are an expansion of the basic DRGs to be more representative of non-Medicare patients and to incorporate severity of illness subclasses. See Diagnosis Related Group (DRG).
