Paravaccinia, unspecified

This code represents an unspecified infection caused by the paravaccinia virus, a member of the Parapoxvirus genus. It typically manifests as a localized skin lesion, often on the hands, and is commonly known as "milker's nodule" due to its occupational association. The condition is generally self-limiting and resolves without specific treatment.

Use this code when documentation confirms a diagnosis of paravaccinia, but the specific type or manifestation is not further detailed. This code is appropriate when the physician explicitly states "paravaccinia, unspecified" or when the clinical picture strongly suggests paravaccinia (e.g., milker's nodule) without additional specificity to allow for a more precise code.

• Avoid using this code if a more specific diagnosis of paravaccinia (e.g., milker's nodule) is documented; look for specific codes within the 051 category.
• Ensure the documentation clearly indicates a viral etiology, specifically paravaccinia, rather than a bacterial or fungal skin infection.
• Consider any associated symptoms or complications that might require additional coding, though paravaccinia is typically uncomplicated.
