Lymphangitis

This code represents an acute or chronic inflammation of the lymphatic vessels, often characterized by red streaks extending from an infection site towards regional lymph nodes. It typically results from a bacterial infection, commonly streptococcal, that has spread into the lymphatic system.

Use this code when documentation clearly indicates inflammation of the lymphatic vessels, such as "lymphangitis" or "streaking lymphangitis." This diagnosis is frequently associated with cellulitis or other localized skin infections.

• Do not confuse with lymphedema (swelling due to lymphatic obstruction), which is a distinct condition.
• Always code the underlying infection (e.g., cellulitis, wound infection) first, if present, as lymphangitis is often a complication.
• Ensure the documentation specifies "lymphangitis" and not just general inflammation or infection.
