What This Code Means

A severe condition where the remaining small intestine cannot absorb enough nutrients and fluids to sustain the body, often requiring long-term nutritional support.

Coding Tips

•Document the underlying cause (short bowel syndrome, Crohn's disease, etc.) when present
•Note dependence on parenteral nutrition or enteral feeding as this affects severity and management

Clinical Significance

Intestinal failure represents the most severe form of malabsorption where the intestines cannot maintain adequate nutrition and hydration independently. This condition carries extremely high morbidity and mortality risk, typically requiring specialized intestinal rehabilitation programs.

Documentation Requirements

✓Documentation of inability to maintain nutrition/hydration via enteral route
✓Long-term parenteral nutrition requirements
✓Underlying cause of intestinal failure
✓Functional assessment of remaining bowel
✓Complications of intestinal failure
✓Specialized management requirements
✓Multidisciplinary team involvement
✓Prognosis and rehabilitation potential

Commonly Confused Codes

K90.821/822 — Short bowel syndrome describes anatomy while intestinal failure describes function K91.2 — Postsurgical malabsorption may not reach intestinal failure severity K90.9 — Unspecified malabsorption is less severe and specific K90.89 — Other malabsorption doesn't capture the failure severity
