Furuncle of limb
ICD-10 L02.42 is a used to indicate a diagnosis of furuncle of limb.
A furuncle, commonly known as a boil, is a painful, pus-filled bump that forms under the skin when hair follicles become infected with bacteria, typically Staphylococcus aureus. Furuncles can occur anywhere on the body but are most common on the limbs, particularly in areas where friction or sweating occurs. Clinically, they present as red, swollen nodules that may eventually rupture and drain pus. The underlying anatomy involved includes the hair follicle, sebaceous glands, and surrounding subcutaneous tissue. Disease progression can vary; while some furuncles resolve spontaneously, others may lead to complications such as abscess formation or systemic infection if not treated appropriately. Diagnostic considerations include a thorough clinical examination and, in some cases, culture of the pus to identify the causative organism. Differential diagnoses may include carbuncles, folliculitis, or other skin infections, necessitating careful evaluation to ensure accurate coding and treatment.

L02.42 specifically covers furuncles located on the limbs, which are characterized by localized infections of hair follicles leading to painful, pus-filled lesions. It does not include other types of skin infections or lesions.
L02.42 should be used when documenting a furuncle specifically on a limb. If the infection is on the face or trunk, the appropriate codes L02.41 or L02.43 should be selected. Accurate anatomical localization is crucial for correct coding.
Documentation should include a detailed clinical assessment of the lesion, including size, location, symptoms, and any treatment provided. Notes on the patient's history of skin infections and any relevant laboratory results, such as cultures, should also be included.
