Furuncle of right lower limb

This code signifies a localized, painful, pus-filled inflammation of a hair follicle and surrounding tissue, specifically located on the right lower extremity. It represents a bacterial infection, typically staphylococcal, resulting in a tender, erythematous nodule that may eventually rupture and drain.

Use this code when documentation clearly indicates a furuncle (boil) affecting any part of the patient's right lower limb, such as the thigh, leg, ankle, or foot. This diagnosis is supported by physician notes describing the characteristic lesion, its location, and often, associated symptoms like pain or tenderness.

• Ensure the documentation specifies "right" lower limb; otherwise, an unspecified laterality code may be more appropriate.
• Distinguish from carbuncles (L02.41-) which involve multiple hair follicles and form a deeper, interconnected lesion.
• Do not use this code for abscesses of skin, subcutaneous tissue, and fascia (L02.-) unless specifically documented as a furuncle.
