Carbuncle of perineum

This code signifies a carbuncle, which is a cluster of interconnected boils forming a deep, painful infection, specifically located in the perineal region. This infection typically involves multiple hair follicles and extends into the subcutaneous tissue, often caused by Staphylococcus aureus.

Apply this code when documentation clearly indicates a carbuncle affecting the perineum. This includes infections involving the area between the anus and the external genitalia. Supporting documentation should detail the location and nature of the infection.

• Differentiate from a single furuncle (boil); a carbuncle involves multiple interconnected lesions.
• Do not use for abscesses or cellulitis of the perineum unless explicitly documented as a carbuncle.
• Consider an additional code for the causative organism (e.g., Staphylococcus aureus) if identified and documented.
