ICD-10 Code K63.8 – Other specified diseases of intestine (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K63.8 – Other specified diseases of intestine
What it is
K63.8 is a catch-all code for intestinal disorders that are documented but do not fit a more specific ICD-10 category. Use it when the chart names a distinct intestinal condition and no better code is available.
Clinical signs
Clinical features vary; refer to documentation. You may see abdominal pain, bowel habit changes, bloating, or abnormal imaging findings tied to a specified intestinal disorder.
When to use this code
Use K63.8 when the provider documents a named intestinal disease, lesion, or disorder that is not indexed elsewhere in ICD-10-CM. It is appropriate when the record is specific enough to support “other specified” but not specific enough for a more exact code. Check documentation if the diagnosis is vague.
Do not use for
Do not use K63.8 for nonspecific abdominal symptoms or for intestinal conditions that have a dedicated ICD-10 code. If the chart says “unspecified intestinal disorder,” choose the unspecified code instead.
Coding tip
Before assigning K63.8, confirm that the provider documented a specific intestinal condition and that no more precise code applies.
