I88.0

What This Code Means

This condition involves swelling and inflammation of the lymph nodes in the membrane that attaches the intestines to the abdominal wall, without a specific identified cause. It often causes abdominal pain and may be mistaken for appendicitis or other serious abdominal conditions.

Coding Tips

• •Verify that the lymphadenitis is truly nonspecific (no identified organism or cause documented) before assigning this code; if a specific cause is identified, use a more specific code
• •This code is often used when imaging shows enlarged mesenteric lymph nodes but clinical workup does not reveal appendicitis, inflammatory bowel disease, or other specific conditions
