I88.1

What This Code Means

This code describes long-term swelling and inflammation of lymph nodes throughout the body, excluding those in the abdominal area around the intestines. It typically results from ongoing infection or inflammation that causes the lymph nodes to remain enlarged over time.

Coding Tips

• •Do not use this code for mesenteric lymphadenitis (inflammation of lymph nodes in the abdomen); use I88.0 instead
• •Specify the location of the lymphadenitis when documented (cervical, axillary, inguinal, etc.) as this may affect code selection or require additional specificity codes
