CPT® Codes — Evaluation and Management Services

This code range includes evaluation and management CPT® codes. The American Medical Association (AMA) maintains the Current Procedural Terminology (CPT®) code set.

The E/M (or E&M) CPT® codes represent services such as office or outpatient services, hospital services (observation and inpatient), emergency department services, critical care, nursing facility services, rest home services, prolonged services, care plan oversight, care management, preventive medicine, and newborn care.

The E/M coding guidelines are essential to accurate coding for these services. The E/M guidelines include definitions of terms that apply to the codes, such as new and established patient, chief complaint, family history, and time. The guidelines also include instructions on choosing the E/M code level.

For unlisted E/M services, meaning those services that do not have a more specific and appropriate CPT® code available, the CPT® E/M codes list includes 99429 for unlisted preventive medicine services and 99499 for unlisted E/M services.
