What This Code Means

A condition where a significant portion of the small intestine has been surgically removed, but it is unclear whether the colon remains connected.

Coding Tips

•Use only when the anatomical status of the colon cannot be determined from documentation
•Query the provider if surgical records are available to specify K90.821 or K90.822 instead

Clinical Significance

Unspecified short bowel syndrome indicates significant malabsorption due to bowel resection but lacks specific anatomical details. This condition requires careful documentation to ensure appropriate risk stratification and management planning.

Documentation Requirements

✓History of significant small bowel resection
✓Evidence of malabsorption syndrome
✓Nutritional support requirements
✓Clinical manifestations of short bowel syndrome
✓Complications related to malabsorption
✓Current management strategies
✓Assessment of remaining bowel function
✓Documentation of why colon status is unspecified

Commonly Confused Codes

K90.821 — Use when colon is documented to be in continuity K90.822 — Use when colon is documented to not be in continuity K91.2 — Postsurgical malabsorption is broader category K90.83 — Intestinal failure defines functional rather than anatomical status
