In the case of a 31-year-old with gallstone, which combination of codes should be used?

• A. K80.30, 99284, 76701
• B. K80.20, 99213, 76700
• C. K80.20, 99283, 76720
• D. K80.20, 99283, 76700

Answer: (D)

When coding this scenario, you build the trio from the clinical problem, the visit level, and the imaging study. The diagnosis should describe gallstones with symptoms but without obstruction, which is coded as K80.20. This avoids implying acute cholecystitis or biliary obstruction unless the chart shows those conditions. For the encounter, the patient’s presentation with gallstone-related symptoms fits an emergency department evaluation of moderate severity, so the appropriate E/M code is 99283. Finally, the imaging should accurately reflect the study performed to assess the gallbladder and biliary tract. A complete abdominal ultrasound code (76700) is used when the exam covers the full abdominal region, including the gallbladder, which is the typical study to evaluate gallstones. Codes for limited studies or for biliary-specific studies would be inappropriate unless the documentation supports a restricted or differently scoped exam. So the best combination is: K80.20, 99283, 76700.
