Cellulocutaneous plague

This code describes a severe, acute bacterial infection of the skin and subcutaneous tissues, characterized by widespread inflammation, erythema, and often necrosis, specifically caused by Yersinia pestis. It represents the cutaneous manifestation of plague, distinct from bubonic or pneumonic forms, though it can occur concurrently or as a progression.

Use this code when documentation clearly indicates a diagnosis of plague with primary involvement of the skin and subcutaneous tissue, often presenting as a large, painful, discolored lesion. Supporting documentation should specify Yersinia pestis infection and describe the characteristic cellulocutaneous presentation.

• Differentiate from other forms of plague (e.g., bubonic, pneumonic) which have distinct codes.
• Ensure documentation specifies the causative organism (Yersinia pestis) to support this diagnosis.
• Consider sequencing with other codes if systemic manifestations or complications are also present.
