Cyst and pseudocyst of pancreas

This code represents an abnormal, fluid-filled sac located within or adjacent to the pancreas. These can be true cysts, which have an epithelial lining, or pseudocysts, which lack such a lining and typically form after pancreatitis or pancreatic injury.

Apply this code when documentation clearly indicates the presence of a pancreatic cyst or pseudocyst. This includes findings from imaging studies (e.g., CT, MRI, ultrasound) or surgical pathology reports confirming the diagnosis.

• Differentiate between true cysts and pseudocysts if specified in the documentation, as this impacts clinical management.
• Do not use this code for pancreatic neoplasms, even if cystic in nature; those require specific morphology codes.
• Code any underlying cause, such as acute or chronic pancreatitis, as an additional diagnosis.
