Cowpox

This code represents a zoonotic viral infection caused by the cowpox virus, typically manifesting as localized skin lesions. It is characterized by pustules, vesicles, and ulcers, often accompanied by fever and lymphadenopathy, and is closely related to vaccinia virus.

Use this code when documentation confirms a diagnosis of cowpox infection, often acquired through contact with infected animals (e.g., cats, rodents) or contaminated materials. Supporting documentation should include clinical findings consistent with cowpox and, ideally, laboratory confirmation of the virus.

• Differentiate from other orthopoxvirus infections, such as vaccinia or monkeypox, which have distinct codes.
• Ensure documentation specifies "cowpox" and not a generic viral skin infection.
• Consider an additional code for any associated complications, such as secondary bacterial infections.
