Step-by-step explanation:
The best choice for coding the patient's encounter based on the provided information is option B. 99213.
The patient presents with abdominal pain, nausea, vomiting, and diarrhea, suggesting a gastrointestinal issue. The abdominal pain is primarily mid-abdominal and has been present for approximately 2 weeks. The patient has been treated previously for arthritis and hypertension and is currently within normal vital signs.
With these symptoms and findings, a level 3 office visit (99213) is appropriate. This code represents an established patient with a problem of low to moderate severity, requiring a detailed history, an expanded problem-focused examination, and straightforward medical decision-making.
