What determines the E&M code billed for a new patient?

• A. Many factors including the medical decision-making and time
• B. Only the stated complaint
• C. The patient’s insurance type
• D. The clinician’s years of experience

Answer: (A)

The key idea is that the E&M code for a new patient is driven by the amount and complexity of work documented, not by a single factor like the initial complaint. In practice, you determine the level of service from what you document in the chart: the depth of history, the extent of the examination, and the complexity of medical decision making. Alternatively, you can use the total time spent on the encounter (including pre- and post-visit work, counseling, and care coordination) to choose the code. This means multiple aspects of the encounter contribute to the code, and time can substitute for some of the other components when enough time is spent. That’s why this option is the best: it acknowledges that several elements—MDM and time, among others—together determine the appropriate code. The other choices don’t fit because a presenting complaint alone doesn’t capture the full workload, insurance type doesn’t influence the coding decision, and the clinician’s years of experience has no bearing on the level of service billed.
