ICD-10 Code K55.8 – Other vascular disorders of intestine (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K55.8 – Other vascular disorders of intestine
What it is
K55.8 identifies vascular disorders of the intestine that do not fit more specific ICD-10 categories. Use it for documented intestinal blood vessel problems when the record does not name a narrower diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Commonly, records may describe abdominal pain, bowel ischemia, or other signs of impaired intestinal blood flow, but you should code only what the provider documents.
When to use this code
Use K55.8 when the clinician documents an intestinal vascular disorder and no more specific code applies. It is appropriate for nonspecific or otherwise classified vascular conditions involving the intestine. If the chart names a specific ischemic or occlusive disorder, use that more precise code instead.
Do not use for
Do not use this code for clearly specified intestinal vascular diagnoses that have their own ICD-10 code. Do not assign it when documentation only suggests abdominal pain or bowel symptoms without a vascular disorder diagnosis.
Coding tip
Look for the exact provider wording and code the most specific intestinal vascular diagnosis documented.
