Furuncle of abdominal wall

This code signifies a localized, painful skin infection (furuncle or boil) occurring specifically on the abdominal wall. It results from bacterial infection of a hair follicle, leading to a pus-filled lesion.

Apply this code when documentation clearly indicates a furuncle located on the patient's abdomen. Supporting documentation would include physician notes detailing the presence, location, and characteristics of a boil on the abdominal wall.

• Differentiate from carbuncles (multiple interconnected furuncles) which have a distinct code.
• Ensure the documentation specifies "abdominal wall" to avoid miscoding with furuncles of other trunk sites.
• Consider an additional code for the causative organism (e.g., Staphylococcus aureus) if identified and documented.
