Carbuncle of limb, unspecified
ICD-10 L02.439 is a billable code used to indicate a diagnosis of carbuncle of limb, unspecified.
A carbuncle is a cluster of interconnected furuncles (boils) that form a painful, pus-filled infection in the skin and subcutaneous tissue. Carbuncles typically occur in areas where hair follicles are present, such as the limbs, neck, and thighs. Clinically, they present as red, swollen lumps that may drain pus and are often accompanied by systemic symptoms such as fever and malaise. The underlying anatomy involved includes the epidermis, dermis, and subcutaneous tissue, where the infection can spread and cause significant inflammation. Disease progression can lead to complications such as abscess formation, cellulitis, or systemic infection if not treated promptly. Diagnostic considerations include a thorough clinical examination, patient history, and, if necessary, laboratory tests to identify the causative organism, commonly Staphylococcus aureus. It is essential to differentiate carbuncles from other skin conditions such as abscesses, folliculitis, and hidradenitis suppurativa to ensure appropriate management.

L02.439 covers carbuncles of the limb that are not specified as to the exact location or type. It includes cases where the infection is localized but does not provide further detail on the limb's specific area.
L02.439 should be used when a carbuncle is present on a limb and no further specification is available. It is appropriate when the clinician has not documented the exact location or if the carbuncle is not classified under other specific codes.
Documentation should include a clear description of the lesion, its location, size, and any associated symptoms. Clinical notes should indicate the diagnosis of a carbuncle and any treatment provided, such as incision and drainage or antibiotic therapy.
