What This Code Means

The pancreas does not produce enough digestive enzymes, leading to difficulty digesting food and nutrient absorption problems.

Coding Tips

  • Often results from chronic pancreatitis, cystic fibrosis, or pancreatic surgery; link to the underlying cause when present
  • Document if patient requires enzyme replacement therapy (pancreatic supplements)

Clinical Significance

Exocrine pancreatic insufficiency represents inadequate pancreatic enzyme production, leading to maldigestion and malabsorption of nutrients. This condition requires lifelong pancreatic enzyme replacement therapy and nutritional monitoring to prevent deficiency states.

Documentation Requirements

  • Clinical evidence of maldigestion (steatorrhea, weight loss)
  • Pancreatic function tests showing reduced enzyme output
  • Documentation of fat-soluble vitamin deficiencies
  • History of chronic pancreatitis, cystic fibrosis, or pancreatic surgery
  • Response to pancreatic enzyme replacement therapy
  • Evidence of malabsorption through stool studies
  • Nutritional assessment showing deficiencies
  • Exclusion of other causes of malabsorption
