Furuncle left hand

This code represents a localized, painful, pus-filled infection of a hair follicle and surrounding tissue, specifically located on the patient's left hand. It is a type of skin abscess caused by bacterial infection, typically Staphylococcus aureus.

Apply this code when documentation clearly indicates a furuncle (boil) affecting any part of the left hand. Supporting documentation should specify the diagnosis of a furuncle and its precise anatomical location on the left hand.

• Differentiate from carbuncles (L02.51-) which involve multiple hair follicles and are typically larger and deeper.
• Ensure laterality is explicitly documented as "left hand" to support this specific code.
• If an underlying cause (e.g., diabetes) is present, code it as a secondary diagnosis.
