Cutaneous abscess of chest wall

This code signifies a localized collection of pus within the skin and subcutaneous tissue of the chest wall, resulting from a bacterial infection. It presents as a tender, inflamed, and often fluctuant mass on the external chest.

Apply this code when documentation clearly indicates a diagnosis of a cutaneous abscess located on the chest wall. Supporting documentation should detail the presence of an abscess, its anatomical location, and clinical signs of infection.

• Differentiate from deeper chest wall infections (e.g., osteomyelitis, empyema) which require different codes.
• Do not use for breast abscesses; specific codes exist for those.
• Ensure the documentation specifies "cutaneous" or "skin and subcutaneous tissue" to confirm the superficial nature of the abscess.
