I want to find all patients with a diagnosis of acute pancreatitis within the i2b2 database, using the ICD-10 and ICD-9 coding system, specifically under the category of diseases of the digestive system (codes K0-K94), and within the subcategory of disorders of the gallbladder, biliary tract, and pancreas (codes K80-K87). The specific code for acute pancreatitis is K85. This query is not restricted by time, and the accuracy scale is set to 100, meaning it is highly accurate. The query will return patients who have this diagnosis as the primary or secondary diagnosis.
