Chronic pancreatitis

This code represents a persistent inflammatory condition of the pancreas, characterized by irreversible morphological changes and typically leading to permanent impairment of pancreatic function. It involves recurrent episodes of abdominal pain, malabsorption, and often diabetes due to progressive destruction of pancreatic tissue.

Apply this code for patients diagnosed with long-standing inflammation of the pancreas, evidenced by chronic abdominal pain, pancreatic insufficiency (e.g., steatorrhea), or imaging findings consistent with chronic changes (e.g., calcifications, ductal dilation). Documentation should clearly indicate the chronicity of the condition, distinguishing it from acute episodes.

• Differentiate from acute pancreatitis (577.0); this code signifies a long-term, irreversible condition.
• Code any associated complications, such as pancreatic pseudocyst (577.2) or diabetes mellitus (250.xx), as secondary diagnoses.
• Ensure documentation specifies "chronic" to support the use of this code, as opposed to recurrent acute episodes without permanent damage.
