Ambulatory Patient Group

Ambulatory Patient Group (APG) is a classification system for outpatient services reimbursement developed for the American Medicare service by the Health Care Financing Administration.^[1] It classifies patients into nearly 300 pathology groups rather than the 14,000 of the International Classification of Diseases.

The APG system is similar to the diagnosis-related groups (DRG), which apply to inpatient care rendered by a hospital.
