Acute lymphangitis of groin

This code signifies an acute bacterial infection of the lymphatic vessels within the groin region, typically presenting as red, tender streaks extending from an infection site. It is characterized by inflammation of the lymphatic channels, often accompanied by fever, chills, and malaise.

Use this code when documentation clearly indicates an acute inflammatory process affecting the lymphatic vessels specifically located in the groin. Supporting documentation should include physical exam findings describing red streaking in the inguinal area, often originating from a distal infection, and a diagnosis of acute lymphangitis.

• Ensure the documentation specifies "acute" and the anatomical site as "groin" to support this specific code.
• Do not confuse with cellulitis (L03.11-) or other localized skin infections, as lymphangitis involves the lymphatic vessels.
• Code any underlying infection (e.g., wound infection, abscess) as a primary diagnosis when applicable, with lymphangitis as a secondary diagnosis.
