Carbuncle of right upper limb

This code signifies a deep, painful skin infection, specifically a carbuncle, located on the patient's right upper extremity. A carbuncle is a cluster of interconnected boils, typically caused by Staphylococcus aureus, forming a localized area of necrosis and pus.

Apply this code when documentation clearly indicates a diagnosis of a carbuncle affecting any part of the right arm, forearm, or hand. Supporting documentation should specify the lesion's nature as a carbuncle and its precise location on the right upper limb.

• Ensure the documentation specifies "carbuncle" and not a single furuncle (boil), as these are distinct conditions.
• Verify the laterality is explicitly stated as "right upper limb" to avoid miscoding to an unspecified or left side.
• Do not use this code for cellulitis or abscesses without the specific characteristic of a carbuncle.
