Cellulitis of perineum

This code signifies an acute bacterial infection of the skin and subcutaneous tissue specifically affecting the perineal region. It presents with localized erythema, warmth, swelling, and tenderness, often accompanied by systemic symptoms like fever and malaise. The infection can spread rapidly if not treated promptly.

Apply this code when documentation clearly indicates cellulitis localized to the perineum. This includes infections of the skin and underlying soft tissue between the anus and the external genitalia. Supporting documentation should detail the location of the infection and clinical signs consistent with cellulitis.

• Differentiate from abscess of the perineum (L02.31) which involves a collection of pus.
• Specify any associated systemic infection (e.g., sepsis) with an additional code.
• Ensure documentation clearly states "perineum" to avoid confusion with other anatomical sites.
