Carbuncle of abdominal wall

This code signifies a carbuncle, which is a severe pyogenic infection of the skin and subcutaneous tissue, specifically located on the abdominal wall. It involves multiple interconnected furuncles (boils) forming a deeper, more extensive inflammatory lesion with several drainage points.

Use this code when documentation clearly states a diagnosis of a carbuncle affecting any part of the abdominal wall. This includes infections of the anterior, lateral, or posterior abdominal wall. Supporting documentation should describe the characteristic features of a carbuncle, such as multiple pustules, deep inflammation, and necrosis.

• Differentiate from a simple furuncle (boil) of the abdominal wall, which would be coded differently.
• Ensure the documentation specifies "carbuncle" and the anatomical site "abdominal wall" to avoid miscoding.
• Consider an additional code for the causative organism if identified and documented (e.g., Staphylococcus aureus).
