Carbuncle of groin

This code represents a deep, painful skin infection in the groin area, characterized by a cluster of interconnected boils (furuncles) that form a single, larger purulent lesion. It is caused by bacterial infection, typically Staphylococcus aureus, and involves multiple hair follicles and subcutaneous tissue.

Assign this code when documentation explicitly states a carbuncle is present in the groin region. This diagnosis is supported by clinical findings such as a painful, inflamed, indurated mass with multiple draining heads in the inguinal or pubic area.

• Ensure documentation specifies "carbuncle" and not just a "boil" or "furuncle" to avoid miscoding.
• Do not use this code for abscesses or cellulitis of the groin unless a carbuncle is specifically diagnosed.
• Consider an additional code for the causative organism (e.g., B95.61 for Methicillin susceptible Staphylococcus aureus infection) if identified and relevant.
