HCPCS code

Name of the Procedure:

  • Common Name: Tdap Vaccine
  • Technical Terms: Tetanus, Diphtheria Toxoids, and Acellular Pertussis Vaccine (G9416)


The Tdap vaccine is an immunization given to protect against three severe bacterial diseases: tetanus, diphtheria, and pertussis (whooping cough). This specific vaccine is administered once to individuals between the ages of 10 and 13.


The Tdap vaccine helps to prevent:

  • Tetanus: A bacterial infection that affects the nervous system, leading to painful muscle contractions, especially of the jaw and neck muscles.
  • Diphtheria: A serious infection of the nose and throat that can block airways, causing breathing difficulties.
  • Pertussis (Whooping Cough): A highly contagious respiratory disease known for severe coughing spells.

The goal is to provide immunity and reduce the incidence and complications associated with these diseases.


  • Scheduled immunization for children and adolescents between the ages of 10 and 13.
  • Necessary for those who have not previously received it or are in need of a booster shot.
  • Important for avoiding outbreaks and protecting public health.


  • No special preparation is typically needed.
  • Patients should inform the healthcare provider of any allergic reactions to previous vaccines or any severe allergies.
  • A brief medical history and current health status evaluation may be conducted.

Procedure Description

  1. The healthcare provider reviews the patient's health records.
  2. The patient or guardian provides verbal or written consent.
  3. The Tdap vaccine is administered via an intramuscular injection, usually in the upper arm.
  4. Post-vaccination, the patient is observed briefly to monitor for any immediate adverse reactions.

Tools/Equipment: Sterile syringe and needle containing the Tdap vaccine. Anesthesia/Sedation: Not required, though a local anesthetic spray or cream can be used to minimize discomfort if desired.


  • The injection itself takes only a few seconds.
  • The entire appointment typically lasts around 10-15 minutes, including preparation and brief observation time.


  • The procedure is usually performed in an outpatient clinic, doctor's office, or school-based health center.


  • Administered by healthcare professionals such as a nurse, medical assistant, or physician.

Risks and Complications

  • Common Risks: Mild pain, redness, or swelling at the injection site, low-grade fever, mild rash, fatigue.
  • Rare Risks: Severe allergic reactions like anaphylaxis, fainting, seizures, high fever.


  • Expected Benefits: Immunity from tetanus, diphtheria, and pertussis.
  • Timeline: Immunity develops within a few weeks of receiving the vaccine.


  • Post-Procedure Care: Keep the injection site clean and dry. Use a cool, damp cloth to reduce swelling and discomfort.
  • Recovery Time: Generally immediate, with minor soreness at the injection site potentially lasting a couple of days.
  • Restrictions/Follow-Up: No restrictions are necessary; follow up as needed if there are signs of severe adverse reactions.


  • Other Options: Alternative combination vaccines like DTaP for younger children or separate vaccinations for each disease.
  • Pros and Cons: Combination vaccines like Tdap simplify the immunization schedule and reduce the number of injections needed.

Patient Experience

  • During Procedure: The patient may feel a brief pinch or sting during the injection.
  • After Procedure: Mild soreness or swelling at the site might occur. Pain can be managed with over-the-counter pain relievers if necessary. Most individuals can resume normal activities immediately.

By getting the Tdap vaccine, patients can significantly reduce their risk of contracting and spreading these potentially life-threatening diseases.
