To determine the correct E/M code, we need to consider the three key components: history, examination, and medical decision making (MDM).
History:
The documentation indicates an expanded problem-focused history. This is supported by the detailed history of present illness, including the patient ' s description of symptoms, family history, and review of systems with pertinent positives and negatives.
Examination:
The examination is also expanded problem-focused. The physician focused on the relevant systems (head, neck, throat) and documented specific findings related to the chief complaint (thyromegaly).
Medical Decision Making:
The MDM is straightforward. The physician is evaluating a new problem (bilateral thyroid nodules) with a low level of risk. Although further workup is planned, this alone doesn ' t automatically increase the MDM complexity.
Based on these components, 99213 is the most appropriate code.
Why other options are incorrect:
99212: Requires a problem-focused history and examination, which is less comprehensive than what was documented.
99214 and 99215: Require a higher level of MDM (low or moderate complexity) and/or a more detailed examination. The documentation doesn ' t support this level of service.
