New codes have been created at category K85, Acute pancreatitis, to uniquely describe idiopathic acute pancreatitis (K85.0-), biliary acute pancreatitis (K85.1-), alcohol induced acute pancreatitis (K85.2-), drug induced acute pancreatitis (K85.3-), other acute pancreatitis (K85.8-) and other diseases of the pancreas (K85.9-). ICD-10-CM further classifies the severity of acute pancreatitis at the 5th digit level as follows:
0 without necrosis or infection
1 with uninfected necrosis
2 with infected necrosis
Acute pancreatitis is an inflammation of the pancreas. It can occur suddenly and will cause pain and swelling in the upper abdominal region, with the pain often radiating to the back. Acute pancreatitis can spread to other organs or develop into chronic pancreatitis if it’s not treated. Physicians who manage patients with acute pancreatitis frequently categorize the severity of this condition by differentiating whether the pancreas is with or without necrosis and/or infection. Tissues altered by necrotizing pancreatitis can potentially develop secondary infection and might require debridement. Infection of the necrotic region of the pancreas occurs secondarily and increases the risk of death significantly.
The Patient Assessment and Outcome Committee of the American Association for the Surgery of Trauma requested specific codes be developed to capture the distinction in the severity of acute pancreatitis. These new codes will assist in tracking and studying these patients.
