Acute lymphangitis of left axilla

This code signifies an acute bacterial infection of the lymphatic vessels, specifically located in the left armpit region. It typically presents as red, tender streaks extending from an infection site towards the axillary lymph nodes, often accompanied by fever and malaise.

Apply this code when documentation clearly indicates an acute inflammatory process of the lymphatic channels affecting the left axilla. This diagnosis is supported by findings such as red streaking, tenderness, and swelling in the specified anatomical area, often secondary to a distal infection.

• Ensure the documentation specifies "acute" and clearly identifies the "left axilla" as the affected site.
• Do not confuse with cellulitis (L03.11-) unless lymphangitis is explicitly documented.
• Code any underlying infection (e.g., wound infection, abscess) as a primary diagnosis if it is the cause of the lymphangitis.
