ICD-10 Code K63.89 – Other specified diseases of intestine (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K63.89 – Other specified diseases of intestine
What it is
K63.89 is used for intestinal disorders that are documented but do not fit a more specific ICD-10-CM code. It captures other specified conditions of the intestine when the provider names the condition clearly.
Clinical signs
Clinical features vary; refer to documentation. You may see abdominal pain, bowel habit changes, distention, or other nonspecific intestinal symptoms depending on the underlying condition.
When to use this code
Use K63.89 when the record identifies a specific intestinal disease that is not indexed to a more exact code. It is appropriate when the provider documents an intestinal condition such as another specified disorder of the bowel and no better code is available. Check documentation for the exact diagnosis wording.
Do not use for
Do not use this code when a more specific intestinal diagnosis is documented or can be coded from the record. Do not use it for unspecified abdominal symptoms alone.
Coding tip
Code the named intestinal condition first if a more specific option exists; use K63.89 only when the documentation supports “other specified” disease.
