Other acute pancreatitis with uninfected necrosis

This code signifies an acute inflammation of the pancreas that has resulted in the death of pancreatic tissue (necrosis), but without evidence of bacterial infection in the necrotic areas. It represents a severe form of acute pancreatitis where tissue damage has occurred.

Apply this code when documentation explicitly states acute pancreatitis with uninfected necrosis, often confirmed by imaging (e.g., CT scan) showing necrotic areas without positive cultures from fine-needle aspiration. This diagnosis typically indicates a more severe clinical course than acute pancreatitis without necrosis.

• Differentiate from infected necrosis (K85.82), which requires positive culture results.
• Ensure the documentation clearly specifies "uninfected" or "sterile" necrosis.
• Always sequence this code as the primary diagnosis when it is the reason for the encounter.
