Carbuncle and furuncle of other specified sites

This code signifies a localized skin infection characterized by a painful, pus-filled lesion (furuncle) or a cluster of interconnected furuncles (carbuncle) occurring on anatomical sites not specifically categorized elsewhere. These infections typically arise from bacterial invasion of hair follicles and surrounding tissue.

Apply this code when documentation specifies a furuncle or carbuncle located on areas such as the trunk, buttocks, or extremities, and the physician's notes confirm the diagnosis. This code is appropriate when the infection is clearly identified as a carbuncle or furuncle and the site is not one of the more specific anatomical locations (e.g., face, neck, anogenital region) covered by other codes.

• Ensure the documentation clearly distinguishes between a furuncle/carbuncle and other skin infections like abscesses or cellulitis.
• Avoid using this code if a more specific anatomical site for the furuncle or carbuncle is documented (e.g., eyelid, ear, nose).
• Consider an additional code for the causative organism if identified and documented (e.g., Staphylococcus aureus).
