There are circumstances in which the initial decision to perform a major surgical procedure is made during an evaluation and management (E&M) service that occurs on the day before or the day of the major surgical procedure. In these circumstances, modifier 57 is used to report the appropriate E&M service to indicate this decision.
As defined by the Centers for Medicare & Medicaid Services (CMS) and applied by the Company, reimbursement for a surgical procedure includes a standard global surgical package, which includes preoperative, intraoperative, and postoperative services.
