Biliary acute pancreatitis with uninfected necrosis

This code signifies an acute inflammation of the pancreas caused by gallstones, where a portion of the pancreatic tissue has died (necrosis) but shows no signs of bacterial infection. This is a severe form of acute pancreatitis, characterized by tissue damage without secondary infection.

Apply this code when documentation explicitly states acute pancreatitis due to biliary obstruction (e.g., gallstones) and confirms the presence of uninfected pancreatic necrosis. Supporting documentation will include imaging reports (CT, MRI) demonstrating necrosis and laboratory results ruling out infection (e.g., negative cultures, normal procalcitonin).

• Ensure the documentation clearly differentiates between infected and uninfected necrosis; if infection is present, a different code is required.
• Always sequence this code after the underlying cause, such as cholelithiasis with obstruction (K80.0x, K80.1x).
• Look for specific terms like "sterile necrosis" or "non-infected necrosis" in the diagnostic statement or pathology reports.
