Arriving in 2021: The Most Significant Changes Made to E/M Coding in a Quarter Century
changes ahead

Late last year, the American Medical Association (AMA) Current Procedural Terminology (CPT) Editorial Panel issued historic coding guidance for office-based and other outpatient evaluation and management (E/M) services (99201-99215). 

These changes are included in the CPT 2021 code set, and are among the most substantial changes made to E/M coding guidance in a quarter of a century. In developing the new guidance, the CPT Editorial Panel sought to reduce administrative burdens, clarify and expand relevant definitions and guidelines, decrease the need for unnecessary or duplicative documentation, and ensure physicians have relevant options for code level selection. 

ISMS’ latest issue brief, Changes Ahead for Office-Based and Other Outpatient Evaluation and Management Codes, offers an overview of the updates and highlights some of the most significant changes.
