Official Description

Tetanus, diphtheria toxoids and acellular pertussis vaccine (Tdap), when administered to individuals 7 years or older, for intramuscular use

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 90715 refers to the Tetanus, diphtheria toxoids, and acellular pertussis vaccine (Tdap), specifically when administered to individuals aged 7 years or older via intramuscular injection. This vaccine is designed to provide long-lasting immunity by stimulating the body's immune system to produce antibodies that target and neutralize specific toxins generated by bacteria. Toxoids, which are inactivated forms of toxins, are utilized in this vaccine to elicit an immune response without the risk of causing disease. The process of creating a toxoid involves culturing the bacteria in a liquid medium, followed by purification and inactivation of the toxic substance they produce. Vaccines like Tdap expose the immune system to altered versions of the bacteria, prompting it to generate its own antibodies. This immunological memory allows the body to respond more effectively upon subsequent exposures to the actual pathogens. Since the immunity conferred by toxoid vaccines can diminish over time, booster doses are recommended to maintain adequate protection. The Tdap vaccine is particularly important for adults and older children, as it combines protection against tetanus, diphtheria, and pertussis, with the acellular pertussis component being a more refined and less reactogenic version of the traditional vaccine, resulting in fewer side effects. It is important to note that the codes associated with these vaccines, such as CPT® Code 90714 for preservative-free tetanus and diphtheria toxoids (Td), and CPT® Code 90715 for the Tdap vaccine, are used solely to report the specific product administered.

1. Indications

The Tdap vaccine (CPT® Code 90715) is indicated for individuals aged 7 years and older to provide protection against three serious bacterial diseases: tetanus, diphtheria, and pertussis. The following conditions highlight the necessity for vaccination:

  • Tetanus: A serious infection caused by the bacterium Clostridium tetani, leading to muscle stiffness and spasms.
  • Diphtheria: A bacterial infection affecting the mucous membranes of the throat and nose, which can lead to severe respiratory issues and complications.
  • Pertussis: Also known as whooping cough, this highly contagious respiratory disease can cause severe coughing fits and is particularly dangerous for infants and young children.

2. Procedure

The administration of the Tdap vaccine involves several key procedural steps to ensure safety and efficacy:

  • Step 1: Patient Assessment - Prior to vaccination, the healthcare provider should assess the patient's medical history, including any previous allergic reactions to vaccines, current health status, and any contraindications to the Tdap vaccine.
  • Step 2: Preparation of the Vaccine - The Tdap vaccine should be prepared according to the manufacturer's instructions. This includes checking the expiration date, ensuring the vaccine is stored at the correct temperature, and shaking the vial gently to mix the vaccine if necessary.
  • Step 3: Site Selection and Injection - The vaccine is administered via intramuscular injection, typically in the deltoid muscle of the upper arm. The injection site should be cleaned with an alcohol swab to minimize the risk of infection.
  • Step 4: Administration of the Vaccine - The healthcare provider should insert the needle at a 90-degree angle to the skin and inject the vaccine slowly. After the injection, the needle should be withdrawn quickly and safely disposed of in a sharps container.
  • Step 5: Post-Administration Observation - After vaccination, the patient should be monitored for a short period to observe for any immediate adverse reactions, such as allergic responses. This is typically done for 15 minutes.

3. Post-Procedure

Following the administration of the Tdap vaccine, patients may experience mild side effects, which can include soreness at the injection site, low-grade fever, or fatigue. These effects are generally short-lived and resolve without intervention. It is important for patients to be informed about potential side effects and when to seek medical attention. Additionally, patients should be advised to keep their vaccination records updated and to follow the recommended schedule for booster doses to maintain immunity against tetanus, diphtheria, and pertussis. Regular follow-up with healthcare providers is encouraged to ensure ongoing protection and to address any concerns regarding vaccination.

59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
X1 Continuous/broad services: for reporting services by clinicians, who provide the principal care for a patient, with no planned endpoint of the relationship; services in this category represent comprehensive care, dealing with the entire scope of patient problems, either directly or in a care coordination role; reporting clinician service examples include, but are not limited to: primary care, and clinicians providing comprehensive care to patients in addition to specialty care

Q6 Service furnished under a fee-for-time compensation arrangement by a substitute physician or by a substitute physical therapist furnishing outpatient physical therapy services in a health professional shortage area, a medically underserved area, or a rural area
TB Drug or biological acquired with 340b drug pricing program discount, reported for informational purposes
UC Medicaid level of care 12, as defined by each state
22 Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service.
24 Unrelated evaluation and management service by the same physician or other qualified health care professional during a postoperative period: the physician or other qualified health care professional may need to indicate that an evaluation and management service was performed during a postoperative period for a reason(s) unrelated to the original procedure. this circumstance may be reported by adding modifier 24 to the appropriate level of e/m service.
25 Significant, separately identifiable evaluation and management service by the same physician or other qualified health care professional on the same day of the procedure or other service: it may be necessary to indicate that on the day a procedure or service identified by a cpt code was performed, the patient's condition required a significant, separately identifiable e/m service above and beyond the other service provided or beyond the usual preoperative and postoperative care associated with the procedure that was performed. a significant, separately identifiable e/m service is defined or substantiated by documentation that satisfies the relevant criteria for the respective e/m service to be reported (see evaluation and management services guidelines for instructions on determining level of e/m service). the e/m service may be prompted by the symptom or condition for which the procedure and/or service was provided. as such, different diagnoses are not required for reporting of the e/m services on the same date. this circumstance may be reported by adding modifier 25 to the appropriate level of e/m service. note: this modifier is not used to report an e/m service that resulted in a decision to perform surgery. see modifier 57 for significant, separately identifiable non-e/m services, see modifier 59.
52 Reduced services: under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. under these circumstances the service provided can be identified by its usual procedure number and the addition of modifier 52, signifying that the service is reduced. this provides a means of reporting reduced services without disturbing the identification of the basic service. note: for hospital outpatient reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well-being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
76 Repeat procedure or service by same physician or other qualified health care professional: it may be necessary to indicate that a procedure or service was repeated by the same physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 76 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
95 Synchronous telemedicine service rendered via a real-time interactive audio and video telecommunications system: synchronous telemedicine service is defined as a real-time interaction between a physician or other qualified health care professional and a patient who is located at a distant site from the physician or other qualified health care professional. the totality of the communication of information exchanged between the physician or other qualified health care professional and the patient during the course of the synchronous telemedicine service must be of an amount and nature that would be sufficient to meet the key components and/or requirements of the same service when rendered via a face-to-face interaction. modifier 95 may only be appended to the services listed in appendix p. appendix p is the list of cpt codes for services that are typically performed face-to-face, but may be rendered via a real-time (synchronous) interactive audio and video telecommunications system.
