Which CPT code represents the most complex new patient exam?

• A. 99202
• B. 99203
• C. 99205
• D. 99204

Answer: (C)

Evaluation and management coding for new patient visits uses levels that reflect how thorough the history, exam, and medical decision making are. The most complex level requires a comprehensive history, a comprehensive exam, and high medical decision making, which signals the deepest level of evaluation for a new patient. That combination is what makes it the highest level among the options, so it represents the most complex new patient exam. The other levels involve progressively less extensive history, smaller scope of examination, and lower medical decision making, fitting less complex cases. In practice, aiming for the highest level typically means more time with the patient and a broader, more detailed assessment and plan.
