What This Code Means

A fluid collection in the pancreas that develops after inflammation or injury but lacks a true epithelial lining, often resulting from pancreatitis.

Coding Tips

• •Pseudocysts are typically complications of acute or chronic pancreatitis; consider linking to the underlying pancreatitis code
• •These may resolve spontaneously or require intervention; document clinical significance

Clinical Significance

Pancreatic pseudocysts are fluid collections lacking epithelial lining, typically developing after pancreatitis episodes. These lesions may resolve spontaneously but can cause complications requiring drainage procedures if large or symptomatic.

Documentation Requirements

• ✓History of prior pancreatitis episode
• ✓Imaging showing fluid collection without epithelial lining
• ✓Time interval since acute pancreatitis (typically >4 weeks)
• ✓Documentation of cyst characteristics and size
• ✓Clinical symptoms if present (pain, early satiety, biliary obstruction)
• ✓Absence of true cyst wall on imaging
• ✓Response to drainage procedures if performed
• ✓Exclusion of other cystic lesions
