Evaluation and Management Services

Facebook Twitter LinkedIn Email


Evaluation and management (E/M) services are cognitive (as opposed to procedural) services in which a physician or other qualified healthcare professional diagnoses and treats illness or injury. Nearly all physicians provide E/M services, however most services that infectious diseases physicians provide are of the E/M type. Appropriate documentation and coding of E/M services are vital to capturing the medical services provided to infectious diseases patients and therefore are also vital for appropriate reimbursement and compensation. IDSA has curated resources for ID physicians and their staff to assist in a better understand E/M coding. 


Updated Evaluation and Management Services Reference Guide

Over the past years, the Centers for Medicare & Medicaid Services has made significant revisions to evaluation and management services, allowing physicians to select the E/M visit level to bill based on either total time spent on the date of patient encounter or the medical decision making used in the provision in the visit. In 2022, changes were established for the office and outpatient setting. In 2023, reforms extended across all health care settings including hospitals, emergency departments, nursing facilities and patients’ homes. 2024 brings an add on complexity code G2211 and split or shared visits. To learn more, check out IDSA’s 2024 Evaluation & Management Services Reference Guide, designed to educate ID physicians on these important changes. More resources and tools to come in 2024!
