Acute lymphangitis of head [any part, except face]

This code signifies an acute bacterial infection of the lymphatic vessels located in any part of the head, excluding the face. It typically presents as red, tender streaks extending from an infection site, accompanied by fever and malaise.

Apply this code when documentation clearly indicates acute inflammation of the lymphatic channels affecting the scalp, ear, or other non-facial head regions. Supporting documentation should specify the acute nature of the infection and its anatomical location within the head.

• Differentiate from cellulitis (L03.211) or erysipelas (A46) of the head, which involve the skin and superficial subcutaneous tissue.
• Ensure the documentation explicitly excludes the face to avoid miscoding with L03.211.
• Code any underlying infection (e.g., wound infection, abscess) as a primary diagnosis, with this code as a secondary diagnosis.
