Which of the following is a key component of an evaluation and management service?

• A. History
• B. Examination
• C. Medical decision making
• D. Counseling

Answer: (A)

In evaluation and management documentation, history is one of the primary elements used to determine the level of service. It captures the patient’s subjective information—the chief complaint, history of present illness, review of systems, and past, family, and social history—which frames the encounter, helps the clinician decide what to examine, and guides medical decision making. While the physical examination and medical decision making are also essential components for determining the level of service, counseling or coordination of care is not counted as a standalone core element in most coding guidelines. It can be documented when significant time is spent or bundled into the other components. So, history is the best answer because it is a foundational element used to establish the context and scope of the evaluation.
