During the postoperative period of a procedure, it may be necessary for the same or different professional provider, or other qualified health care professional from the same provider group, to perform a subsequent procedure or service that is unrelated to the initial procedure or service. In such cases Modifier 79 is appended to the procedure code(s) to indicate that the procedure(s) or service(s) performed is/are unrelated to the initial procedure.
As used in this policy, postoperative period refers to the period of time following a surgical or other invasive procedure during which reimbursement for certain procedures or services is included in the global surgical reimbursement to the professional provider or provider group.
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.
