Cellulocutaneous plague

This code signifies a severe bacterial infection caused by Yersinia pestis that affects both the skin and subcutaneous tissues. It is characterized by localized inflammation, swelling, and often necrosis of the skin, in addition to systemic symptoms of plague. This form of plague is distinct from bubonic, septicemic, or pneumonic presentations.

Assign this code when documentation clearly indicates a diagnosis of plague with specific involvement of the skin and underlying connective tissue. This diagnosis typically follows laboratory confirmation of Yersinia pestis and clinical signs consistent with cellulitis or cutaneous lesions in a patient with plague. Use this code when the skin involvement is a primary and significant manifestation.

• Differentiate from other forms of plague (e.g., bubonic, septicemic) which have distinct ICD-10-CM codes.
• Ensure documentation specifies "cellulocutaneous" or similar language indicating both skin and subcutaneous tissue involvement.
• Always sequence this code as the primary diagnosis when it is the reason for the encounter.
