Drug induced acute pancreatitis with infected necrosis

This code signifies an acute inflammation of the pancreas caused by a medication, where the pancreatic tissue has undergone necrosis (tissue death) and subsequently become infected. This is a severe form of drug-induced pancreatitis, characterized by both tissue damage and superimposed infection.

Use this code when documentation clearly states acute pancreatitis is due to a drug, and imaging or surgical findings confirm infected pancreatic necrosis. This typically involves patients presenting with severe abdominal pain, elevated pancreatic enzymes, and evidence of infection (e.g., fever, leukocytosis) alongside necrotic areas in the pancreas.

• Ensure the medical record explicitly links the pancreatitis to a specific drug.
• Verify documentation confirms both necrosis and infection; "sterile necrosis" would be coded differently.
• Code the specific drug causing the pancreatitis using an external cause code (T36-T50 series) in addition to this diagnosis.
