[Verified Answer]: You are a hospital inpatient coder

You are a hospital inpatient coder. Your task is to review the codes assigned by the CAC system and verify their accuracy. Review the following scenarios. For each scenario: Identify the errors in the codes assigned by the CAC. Explain why these codes are incorrect based on official coding guidelines and the clinical information provided. Determine and list the correct codes that should have been assigned for this patient’s diagnosis and related conditions. Scenario 3 Jackie Eastport, a 55-year-old female patient, was admitted after experiencing severe abdominal pain and vomiting for two days. The attending physician documented: “Patient reports sudden onset of severe epigastric pain radiating to the back, associated with nausea and vomiting. Physical exam reveals tenderness in the epigastric region. Laboratory tests show elevated serum lipase. Abdominal ultrasound indicates inflammation around the pancreas, suggestive of pancreatitis.” The Computer-Assisted Coding (CAC) system automatically assigned the following codes: K85.9 – Acute pancreatitis, unspecified R10.9 – Unspecified abdominal pain K80.00 – Calculus of the gallbladder with acute cholecystitis, without obstruction The CAC report indicates the codes are based on the documentation, but does not account for the specific diagnosis or the clinical findings in detail. Additional Clinical Details (for your analysis): The elevated serum lipase and ultrasound findings support a diagnosis of acute pancreatitis. The physician notes no evidence of gallstones or biliary obstruction on ultrasound. The patient has no history of gallstones or prior pancreatic issues. The abdominal pain is localized to the epigastric region and radiates to the back. No signs of cholecystitis or gallbladder stones are documented.
