Acute lymphangitis of chest wall

This code signifies an acute bacterial infection of the lymphatic vessels located in the chest wall. It typically presents as red, tender streaks extending from an infection site, accompanied by fever and malaise. This condition indicates an inflammatory response within the lymphatic system of the thoracic region.

Apply this code when documentation explicitly states acute lymphangitis affecting the chest wall. Supporting documentation should include clinical findings such as red streaking, tenderness, and systemic signs of infection localized to the chest. This code is appropriate for both primary and secondary diagnoses depending on the clinical scenario.

• Ensure documentation specifies "acute" and "chest wall" to differentiate from chronic or other anatomical sites.
• Always code the underlying infection (e.g., cellulitis, wound infection) that caused the lymphangitis first, if known.
• Do not confuse with cellulitis of the chest wall (L03.113) unless lymphangitis is specifically documented as well.
