EM Coding

The EM code, the evaluation and management code, is used to classify patient encounters based on the complexity of healthcare professionals' evaluation and management services.

ED stands for Emergency Department, and refers to emergency department services in a hospital facility. EM refers to Evaluation and Management, the process of assessing and managing patient health during clinical encounters.

CPT codes identify specific medical procedures and services. EM codes, a subset of CPT, specifically classify evaluation and management encounters involving cognitive services delivered by medical service providers.
