Carbuncle of neck

This code describes a deep-seated, painful infection of the skin and subcutaneous tissue on the neck, characterized by a cluster of interconnected boils (furuncles) with multiple drainage points. It is typically caused by Staphylococcus aureus and presents as a red, swollen, and tender mass.

Use this code when documentation explicitly states a carbuncle located on the neck. This diagnosis is supported by physical examination findings of a localized, inflamed, and often suppurative lesion on the posterior or lateral aspects of the neck.

• Ensure documentation specifies "carbuncle" and not just a general skin abscess or furuncle.
• Do not confuse with codes for cellulitis or other localized skin infections, which have distinct clinical presentations.
• Consider an additional code for the causative organism (e.g., Staphylococcus aureus) if identified and documented.
