Tanapox virus disease

This code identifies a rare viral infection caused by the Tanapox virus, characterized by the development of skin lesions. The disease typically presents with a sudden onset of fever, headache, and malaise, followed by the appearance of a limited number of papules that progress to nodules and then ulcerate, eventually healing with scarring.

Assign this code when documentation confirms a diagnosis of Tanapox virus infection. This typically involves a patient presenting with characteristic skin lesions and systemic symptoms, with laboratory confirmation of the virus or a strong epidemiological link. Use this code for both confirmed and highly suspected cases based on clinical presentation in an endemic area.

• Ensure the documentation clearly specifies "Tanapox" to differentiate from other poxvirus infections.
• Do not confuse with other viral exanthems or localized skin infections; laboratory confirmation or a definitive clinical diagnosis is crucial.
• Code any associated symptoms or complications, such as fever or secondary bacterial infections, in addition to this primary diagnosis.
