CPT E/M Companion 2023

The CPT E/M Companion 2023 is the definitive AMA-authored supplement reference guide to accompany the Current Procedural Terminology CPT 2023 Professional Edition.

CPT E/M Companion 2023 is intended to help users understand and navigate the 2023 E/M revisions that have been made across numerous service groups, namely inpatient and observation care services; consultations services; emergency department services; nursing facility services; home and residence services; and prolonged services.

To enable consistency with the 2021 revisions to the E/M office and other outpatient codes, the 2023 E/M changes will provide users with a streamlined set of E/M guidelines that apply across multiple sites of service; revisions to code descriptors that reflect the structure approved in the office visit revisions; and a uniform Medical Decision Making (MDM) table for all the sites of services noted, as well as office or other outpatient visits.

This AMA-authored publication is designed with intermediate users in mind. Therefore, this publication’s content is written and organized in a manner that will make sense to all intermediate users familiar with the E/M section of the CPT code set. To conserve space and to maximize the value-added content, this publication does not reproduce most of the tables or guidelines in the CPT 2023 Professional Edition.
