Need for prophylactic vaccination and inoculation against varicella

This code signifies a patient's requirement for preventive immunization against varicella, commonly known as chickenpox. It indicates that the patient is being seen for the purpose of receiving the varicella vaccine to prevent future infection.

This code is appropriate for encounters where a patient presents specifically for varicella vaccination. This includes routine childhood immunizations, catch-up vaccinations for adolescents or adults, or vaccination for individuals with no history of chickenpox or prior vaccination.

• Always code the administration of the vaccine (CPT code) in conjunction with this diagnosis.
• Do not use this code if the patient is being treated for an active varicella infection.
• Ensure documentation clearly states the purpose of the visit is for prophylactic vaccination.
