ICD-10 Code K85.92 – Acute pancreatitis with infected necrosis, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K85.92 – Acute pancreatitis with infected necrosis, unspecified
What it is
This code identifies acute pancreatitis complicated by infected pancreatic necrosis, without further detail on the cause or extent. Use it when documentation confirms infection within necrotic pancreatic tissue.
Clinical signs
Typical findings include acute abdominal pain, nausea, vomiting, and signs of systemic illness. Clinical features vary; refer to documentation, especially for imaging or procedural evidence of infected necrosis.
When to use this code
Use K85.92 when the record states acute pancreatitis with infected necrosis and does not specify a more precise pancreatitis subtype. It is appropriate when the provider documents infected necrosis, abscess, or infected pancreatic collections linked to acute pancreatitis. Check documentation if the infection is uncertain or if necrosis is present without infection.
Do not use for
Do not use this code for acute pancreatitis without necrosis, or for sterile necrosis only. If the chart does not clearly document infection of necrotic tissue, check documentation.
Coding tip
Code the condition only when infected necrosis is explicitly documented; “necrosis” alone is not enough.
