ICD-10 Code K85.80 – Other acute pancreatitis without necrosis or infection (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K85.80 – Other acute pancreatitis without necrosis or infection
What it is
This code identifies an acute inflammation of the pancreas that does not involve pancreatic necrosis or infection. Use it when the episode is acute and the documentation does not support a more specific pancreatitis type.
Clinical signs
Typical findings include sudden upper abdominal pain, nausea, vomiting, and abdominal tenderness. Clinical features vary; refer to documentation, imaging, and the provider’s final diagnosis for confirmation.
When to use this code
Use K85.80 when the record states acute pancreatitis and specifically notes no necrosis or infection, but does not name another coded subtype. It also fits cases documented as other acute pancreatitis without those complications. If the chart identifies gallstone, alcohol-induced, drug-induced, or idiopathic pancreatitis, use the more specific code instead.
Do not use for
Do not use this code for chronic pancreatitis, pancreatic necrosis, or infected pancreatic necrosis. Check documentation if the provider describes a different etiology or complication.
Coding tip
Always code the most specific acute pancreatitis type documented, and confirm that necrosis and infection are both absent before selecting K85.80.
