Acute lymphangitis of umbilicus

This diagnosis code signifies an acute bacterial infection of the lymphatic vessels surrounding the navel. It is characterized by inflammation and often presents as red streaks radiating from the umbilicus, accompanied by pain, tenderness, and sometimes fever.

Apply this code when documentation clearly indicates an acute inflammatory process of the lymphatic system specifically affecting the umbilical region. This typically occurs secondary to a local infection or skin breakdown in the area. Supporting documentation should describe the acute nature and the umbilical location.

• Ensure documentation specifies "acute" and "umbilicus" to differentiate from chronic or other anatomical sites.
• Code any underlying infection (e.g., cellulitis, omphalitis) as a primary diagnosis if it is the cause of the lymphangitis.
• Do not confuse with cellulitis of the umbilicus (L03.116) unless lymphangitis is also explicitly documented.
