ICD-10 Code K85.10 – Biliary acute pancreatitis without necrosis or infection (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K85.10 – Biliary acute pancreatitis without necrosis or infection
What it is
K85.10 identifies acute pancreatitis caused by biliary disease, such as gallstones or biliary obstruction, without pancreatic necrosis or infection. Use it when the record clearly links the pancreatitis to a biliary source.
Clinical signs
Typical findings include acute upper abdominal pain, nausea, vomiting, and evidence of pancreatitis on clinical evaluation or imaging. Clinical features vary; refer to documentation.
When to use this code
Use K85.10 when the provider documents acute pancreatitis and specifies a biliary cause, while also stating there is no necrosis or infection. It fits cases tied to gallstones, biliary sludge, or other documented biliary obstruction. If the cause or complication status is unclear, check documentation.
Do not use for
Do not use this code if the pancreatitis is nonbiliary, chronic, or documented with necrosis or infection. Also avoid it when the record only says “pancreatitis” without a confirmed biliary cause.
Coding tip
Verify both the biliary etiology and the absence of necrosis or infection before assigning K85.10.
