• A. K35.80 and 99281
• B. K35.2 and 99285
• C. K31.9 and 99283
• D. K35.80 and 99291

Answer: (A)

In this scenario, coding combines the presenting problem with the appropriate emergency department evaluation and management level. The patient has signs and symptoms of acute appendicitis, and the case fits acute appendicitis coded as K35.80 when there’s no documentation of perforation, abscess, or peritonitis. The ED encounter led directly to surgical management after consent, which aligns with a straightforward ED evaluation and immediate disposition, corresponding to CPT 99281. Higher levels of ED service would require more extensive documentation of history, exam, and medical decision making (or critical care), which isn’t described here. So the pair K35.80 and 99281 best matches the scenario.
