I89: Other noninfective disorders of lymphatic vessels and lymph nodes
I89.8: Other specified noninfective disorders of lymphatic vessels and lymph nodes
Fluid forms in tissue throughout the body every day. This tissue fluid is the lymph. The lymph is carried around the body by lymph vessels. The lymph vessels run around the entire body and are connected to blood vessels. At some points, there are lymph nodes along the lymph vessels. Pathogens are rendered harmless in the lymph nodes, for example.
Your lymph vessels or lymph nodes have changed. As a result, the lymph is sometimes unable to flow through the body properly. This can cause the tissue to become inflamed and be painful.
