Cellulitis of umbilicus

This code signifies an acute bacterial infection of the skin and subcutaneous tissue surrounding the umbilicus. It presents with localized erythema, warmth, swelling, and tenderness, often accompanied by fever and malaise.

Apply this code when documentation clearly indicates cellulitis specifically affecting the umbilical region. This is common in neonates (omphalitis) but can occur in adults, particularly with poor hygiene, obesity, or recent umbilical piercing/surgery. Supporting documentation should detail the location of the infection.

• Ensure the documentation specifies "umbilicus" as the site of cellulitis; do not use for generalized abdominal cellulitis.
• Consider an additional code for the causative organism (e.g., B95.x, B96.x) if identified and documented.
• Distinguish from omphalitis (P38.x) which is specifically for neonatal umbilical infections.
