Other acute pancreatitis with infected necrosis

This code signifies an acute inflammation of the pancreas complicated by the presence of infected necrotic tissue. This involves the death of pancreatic tissue due to the inflammatory process, further exacerbated by a bacterial or fungal infection within the necrotic areas. It represents a severe form of acute pancreatitis with a high risk of systemic complications.

Use this code when documentation explicitly states acute pancreatitis with infected necrosis. This diagnosis is typically supported by imaging studies (e.g., CT scan with contrast showing non-enhancing areas consistent with necrosis) and microbiological evidence of infection (e.g., positive culture from fine-needle aspiration of necrotic tissue).

• Ensure documentation clearly distinguishes between sterile and infected necrosis; this code is only for infected necrosis.
• Do not use this code for sterile necrosis; refer to K85.81 (Other acute pancreatitis with sterile necrosis).
• Code any associated organ failure or systemic complications separately, following sequencing guidelines.
