Cellulitis of chest wall

This code represents an acute bacterial infection of the dermis and subcutaneous tissue affecting the chest wall. It typically presents with localized erythema, warmth, swelling, and tenderness in the thoracic region, excluding the breast.

Apply this code when documentation specifies cellulitis located on the chest wall. This includes infections of the anterior, lateral, or posterior thoracic wall. Supporting documentation should clearly indicate the anatomical site of the infection.

• Differentiate from cellulitis of the breast (N61.0, N61.1), which has specific codes.
• Do not use for abscesses of the chest wall; these are coded separately (e.g., L02.211, L02.212, L02.213).
• Code any associated systemic infection (e.g., sepsis) or underlying conditions as additional diagnoses.
