A 2-year-old boy with bacterial pneumonia was hospitalized and had 5 days of antibiotic therapy and the patient was discharged last week. Today, his mother brings him to the office because he has developed a fever of 101° F with a mild rash on his torso. The patient was last seen in our office 6 months ago for his well-child exam. His pediatrician performed a problem-focused history and examination. The MDM complexity was low. Which E/M code is assigned?
