Furuncle of right axilla
ICD-10 L02.421 is a billable code used to indicate a diagnosis of furuncle of right axilla.
Furuncle of the right axilla, commonly known as a boil, is a painful, pus-filled bump that forms under the skin when hair follicles become infected. This condition is primarily caused by Staphylococcus aureus bacteria, which can enter the skin through small cuts or abrasions. The axilla, or armpit area, is particularly susceptible due to moisture and friction, making it a common site for furuncles. Clinically, patients present with localized swelling, redness, and tenderness, often accompanied by systemic symptoms such as fever if the infection is severe. Disease progression typically involves the formation of a painful nodule that may eventually rupture and drain pus. Diagnostic considerations include a thorough physical examination and, if necessary, culture of the pus to identify the causative organism. In some cases, underlying conditions such as diabetes or immunosuppression may predispose individuals to recurrent furuncles, necessitating further evaluation and management.

L02.421 specifically covers furuncles located in the right axilla. It is important to differentiate this from other skin infections such as carbuncles (L02.42) or abscesses (L02.9).
L02.421 should be used when the furuncle is confirmed to be in the right axilla, as opposed to other locations or types of skin infections. Accurate localization is key for proper coding.
Documentation should include a detailed description of the lesion, its location, symptoms, treatment provided, and any laboratory results, such as cultures, that confirm the diagnosis.
