ICD-10 Code K86.2 – Cyst of pancreas (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K86.2 – Cyst of pancreas
What it is
K86.2 identifies a cyst in the pancreas, meaning a fluid-filled sac or cystic lesion in or on the pancreas. Use it when the record documents a pancreatic cyst without a more specific diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Many pancreatic cysts are found incidentally on imaging, while others may be associated with abdominal pain, pancreatitis, or ductal changes noted by the clinician.
When to use this code
Use K86.2 when the provider documents a pancreatic cyst, cystic lesion, or similar wording and does not specify a different pancreatic disorder. It is appropriate for imaging or consultation notes that clearly identify a cyst of the pancreas. If the note names a more specific cyst type or another pancreatic condition, code that diagnosis instead.
Do not use for
Do not use this code for pancreatic pseudocyst, pancreatitis, or other non-cystic pancreatic diseases. If the documentation is unclear about the lesion type, check documentation.
Coding tip
Capture the exact provider wording and confirm whether the cyst is described as pancreatic, pseudocystic, or otherwise specified before assigning K86.2.
