The primary benefit of an AP-DRG is that it is the only inpatient classification method applicable to all patient populations, no matter their age. AP-DRGs also group together patients who require the same intensity for resources and a similar clinical perspective.
What is the difference between a DRG, MS-DRG, and AP-DRG?
Diagnosis-related groups can come in a few different categories, with each different type accounting for different medical factors. A basic DRG only measures a patient’s resource utilization while staying at a hospital on one or two levels of severity.
The “MS” in MS-DRG stands for “Medicare severity” and refers to DRGs given specifically to Medicaid and Medicare patients. Additionally, an MS-DRG measures the patient’s severity of illness and risk of mortality while admitted on up to three levels of severity.
AP-DRGs are similar to regular and MS-DRGs but also include a more detailed DRG breakdown for non-Medicare patients, particularly newborns and children.
