The New York Products of Ambulatory Surgery (PAS) patient classification system was implemented by the state of New York for reimbursement of Medicaid ambulatory surgery claims. Using a national claims-based database, the PAS system was evaluated for use with emergency department-generated surgical episodes. The PAS system performed well, but would benefit from the inclusion of age, comorbidity, and presence of multiple surgical procedures. Further, model power increased significantly when focused on total episode versus surgical charges alone. The study indicated the high degree to which emergency department-generated charges are closely tied to other charges in any overall care delivery system.
