In this episode, Rich explores how many intraoperative neurophysiological monitoring (IONM) cases are performed annually in the U.S.—and why it’s surprisingly hard to get a straight answer. He breaks down the limitations of large claims databases, introduces alternative methods for estimating case volume, and highlights key insights into the number of active CNIMs and their average case loads. Rich also discusses historical trends, future growth projections, and what all of this means for the IONM workforce over the next decade.
