Pseudocowpox [milker's node]

This code represents pseudocowpox, also known as milker's node, a viral skin infection typically characterized by single or multiple reddish-brown papules or nodules, often with a central depression or crust. It is a zoonotic infection primarily transmitted from cattle to humans.

Use this code when documentation confirms a diagnosis of pseudocowpox, commonly seen in individuals with occupational exposure to cattle, such as dairy farmers or veterinarians. The diagnosis is typically made clinically based on characteristic lesions and exposure history.

• Ensure documentation specifies "pseudocowpox" or "milker's node" to differentiate from other poxvirus infections.
• Do not confuse with true cowpox (B08.01) or other viral warts.
• Consider adding an external cause code (e.g., W55.21XA for contact with cow) if the exposure is documented.
