Carbuncle of right hand

This code signifies a deep, painful, and often pus-filled infection of the skin and subcutaneous tissue on the right hand, typically involving multiple hair follicles. It presents as a cluster of interconnected boils, forming a larger, more severe lesion than a single furuncle.

Apply this code when documentation clearly indicates a carbuncle specifically located on the patient's right hand. Supporting documentation should describe the characteristic appearance of a carbuncle, such as multiple draining heads or a larger, indurated lesion, and specify the right hand as the affected site.

• Ensure the documentation differentiates between a carbuncle and a furuncle (boil), as a carbuncle is a more extensive infection.
• Verify the laterality (right hand) is explicitly stated in the medical record.
• Do not use this code for cellulitis or abscesses that are not specifically described as carbuncles.
