Carbuncle and furuncle of buttock

This code represents a localized skin infection characterized by a painful, pus-filled lesion (furuncle) or a cluster of interconnected furuncles (carbuncle) specifically located on the buttock. These infections originate in hair follicles and surrounding subcutaneous tissue, often caused by Staphylococcus aureus.

Use this code when documentation clearly specifies a furuncle or carbuncle affecting the gluteal region. Supporting documentation should include the anatomical site of the infection and a diagnosis of either a furuncle or carbuncle.

• Differentiate from cellulitis or abscesses of the buttock, which are coded differently.
• Ensure the documentation specifies "buttock" as the anatomical site; other sites have distinct codes.
• Consider an additional code for the causative organism if identified and documented (e.g., Staphylococcus aureus).
