Acute lymphangitis of abdominal wall

This code describes an acute inflammatory condition affecting the lymphatic vessels within the abdominal wall. It is characterized by red streaks, tenderness, and swelling, indicating an infection spreading through the lymphatic system in this specific anatomical region.

Use this code when documentation clearly indicates an acute bacterial or viral infection of the lymphatic vessels confined to the abdominal wall. Supporting documentation should include physical exam findings such as erythema, streaking, and tenderness along lymphatic pathways, often accompanied by fever or regional lymphadenopathy.

• Ensure the documentation specifies "acute" and "abdominal wall" to differentiate from chronic or other anatomical sites.
• Code any underlying infection (e.g., cellulitis, wound infection) as the primary diagnosis, with this code as a secondary diagnosis.
• Do not confuse with cellulitis of the abdominal wall (L03.115) unless lymphangitis is explicitly documented as a distinct finding.
