Need for prophylactic vaccination and inoculation against pertussis alone

This code indicates an encounter for the sole purpose of receiving a preventive vaccination against pertussis. It signifies that the patient is presenting for immunization to protect against whooping cough, without any other associated medical concerns or symptoms.

This code is appropriate for routine childhood immunizations, booster shots for adolescents or adults, or vaccination of individuals in close contact with infants or immunocompromised persons. It should be used when pertussis vaccination is the primary reason for the visit.

• Do not use this code if the patient is receiving a combination vaccine (e.g., DTaP, Tdap); a more specific combination vaccine code would be appropriate.
• Ensure the medical record clearly documents the administration of a pertussis-only vaccine.
• This code is for the need for vaccination; a separate procedure code for the vaccine administration will also be required.
