Two surgeons with expertise in general surgery coding and reimbursement, Linda M. Barney, MD, FACS—Associate Professor of Surgery and Director of the Division of General Surgery at Wright State Physicians (Dayton, OH)—and Megan E. McNally, MD, FACS—Assistant Clinical Professor in the Department of Surgery at the University of Missouri-Kansas City School of Medicine—outlined new reporting guidelines that will be applied to code selection for office and other outpatient E/M services effective January 1, 2021.

Drs. Barney and McNally shared insights about the revisions made to the office and other outpatient E/M code set by the Current Procedural Terminology Editorial Panel, including new requirements related to history and physician examination, physician time, and medical decision making associated with E/M visits.
