Article Overview

This article discusses the coding challenge of distinguishing between two commonly confused E/M-related modifiers in surgical scenarios. It is aimed at coders, billers, and revenue cycle staff who need to understand when a preoperative visit may be separately reported and how payer expectations can differ for minor versus major procedures. The piece presents practitioner perspectives and broad guidance about decision-to-operate situations, related global periods, and when a separate diagnosis or unrelated service may matter.
