2The CPT E/M Companion 2023 is the definitive AMA-authored supplement reference guide to the Current Procedural Terminology (CPT(R)) 2023 Professional Edition. It is designed to help users understand the changes to certain evaluation and management (E/M) services; how to report these new and revised or consolidated codes; and how to apply the revised and new guidelines effective Jan 1, 2023.

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.

In addition to the CPT E/M Companion 2023, the AMA has also created a special section for E/M 2023 in the CPT Knowledge Base. For more information on this you can go to ama-assn.org/cpt-knowledge-base.
