Carbuncle of face

This code describes a severe bacterial infection of the hair follicles and surrounding subcutaneous tissue on the face, characterized by a cluster of interconnected boils. It presents as a painful, inflamed, and often suppurative lesion that can be deep-seated and may drain multiple pustules.

Use this code when documentation clearly indicates a carbuncle located specifically on any part of the face (e.g., cheek, forehead, chin). This diagnosis is typically supported by physical examination findings describing a large, multi-headed purulent lesion.

• Differentiate from a simple furuncle (boil) of the face, which is a single infected hair follicle.
• Specify any associated complications, such as cellulitis (L03.211) or sepsis, with additional codes.
• Ensure the documentation explicitly states "carbuncle" and "face" to support this specific code.
