Carbuncle of right lower limb

This code signifies a carbuncle, which is a severe pyogenic infection of the skin and subcutaneous tissue, characterized by a cluster of interconnected boils. It typically presents as a painful, inflamed, and indurated lesion with multiple draining sinuses. This specific code indicates the carbuncle is located on the patient's right lower limb.

Use this code when documentation clearly identifies a carbuncle affecting any part of the right lower extremity, such as the thigh, leg, ankle, or foot. Supporting documentation should include a physician's diagnosis of carbuncle and specify the right lower limb as the anatomical site of the infection.

• Ensure the documentation specifies "carbuncle" and not a single furuncle (boil), as these are distinct conditions.
• Verify the laterality; this code is specific to the right lower limb. If the carbuncle is on the left lower limb, a different code is required.
• Consider additional codes for any associated complications, such as cellulitis or sepsis, if documented.
