Need for prophylactic vaccination and inoculation against diphtheria alone

This code indicates a patient's need for preventive immunization specifically against diphtheria. It signifies that the patient is being given a vaccine to protect them from contracting diphtheria, a serious bacterial infection.

This code is used when a patient presents for a diphtheria-only vaccination. This may occur as part of a routine immunization schedule, catch-up vaccinations, or when diphtheria is the sole component of a multi-antigen vaccine being administered for prophylactic purposes.

• Ensure the documentation clearly specifies diphtheria as the target of the vaccination.
• Do not use this code if the vaccination is for diphtheria combined with tetanus (DT) or diphtheria, tetanus, and pertussis (DTaP/Tdap) unless diphtheria is the only component being addressed.
• This code is for the need for vaccination; a procedure code for the administration of the vaccine will also be required.
