Other acute pancreatitis without necrosis or infection

This code represents an acute inflammatory condition of the pancreas that does not involve tissue death (necrosis) or a confirmed infection. It signifies a sudden onset of pancreatic inflammation where the primary pathology is not severe enough to cause tissue destruction or secondary infection.

Use this code for patients diagnosed with acute pancreatitis where imaging and laboratory findings do not indicate necrosis or infection. Documentation should clearly state "acute pancreatitis" without mention of necrotizing or infected components, or explicitly state "acute pancreatitis without necrosis or infection."

• Differentiate from K85.1- (idiopathic acute pancreatitis) and K85.2- (gallstone acute pancreatitis) when the etiology is known.
• Ensure documentation explicitly rules out necrosis and infection; otherwise, a more specific code may be appropriate.
• Always code the underlying cause of the acute pancreatitis first, if known (e.g., gallstones, alcohol abuse).
