Carbuncle of unspecified foot
ICD-10 L02.639 is a billable code used to indicate a diagnosis of carbuncle of unspecified foot.
L02.639 refers to a carbuncle of the unspecified foot, which is a painful cluster of boils that form a connected area of infection beneath the skin. Carbuncles are typically caused by Staphylococcus aureus bacteria and can occur when hair follicles become infected. Clinically, patients may present with red, swollen lumps that can be tender to the touch, often accompanied by fever and malaise in more severe cases. The anatomy involved includes the skin and subcutaneous tissue of the foot, where the infection can lead to abscess formation. Disease progression can vary; if untreated, carbuncles may drain spontaneously or require surgical intervention. Diagnostic considerations include a thorough clinical examination and, if necessary, culture of the pus to identify the causative organism. Differential diagnoses may include other skin infections such as furuncles, cellulitis, or abscesses, which necessitate careful evaluation to ensure appropriate treatment.

L02.639 specifically covers carbuncles located on the foot, which are characterized by the presence of multiple interconnected boils. It does not include other types of skin infections or lesions that may appear on the foot.
L02.639 should be used when the carbuncle is specifically located on the foot and no further specification is available. If the carbuncle is located on another part of the body, or if it is a single boil, other codes should be considered.
Documentation should include a detailed clinical assessment of the carbuncle, including its location, size, symptoms, and any laboratory results that confirm the diagnosis. Photographic evidence may also be beneficial.
