Carbuncle of right foot

This code describes a deep-seated, painful infection of the skin and subcutaneous tissue on the right foot, characterized by a cluster of interconnected boils with multiple drainage points. It typically results from bacterial infection, often Staphylococcus aureus, and can be accompanied by fever and malaise.

Use this code when documentation explicitly states a carbuncle is present on the patient's right foot. Supporting documentation should detail the location and nature of the lesion, distinguishing it from a single furuncle or other skin infections.

• Ensure the documentation specifies "carbuncle" and not just "abscess" or "boil" to differentiate from codes like L02.611 (Cutaneous abscess of right foot).
• Verify the laterality is "right foot" to avoid miscoding with L02.632 (Carbuncle of left foot) or L02.639 (Carbuncle of unspecified foot).
• Code any associated systemic infections (e.g., cellulitis, sepsis) separately, if documented.
