TdVax is gone, but patients still face Tenivac and Tdap vaccine costs. This provider guide covers insurance, patient assistance, and how to help patients avoid paying out of pocket.

The permanent discontinuation of TdVax in 2024 has changed how providers and patients navigate tetanus-diphtheria vaccination. While the availability challenge has garnered the most attention, a closely related concern is cost: specifically, making sure that patients who need Tenivac, Adacel, or Boostrix can access them without facing unexpected out-of-pocket expenses. This guide is designed for providers who want to proactively help patients understand their coverage and minimize vaccine costs.

The Good News: Most Patients Should Pay $0

The most important savings message for your patients: for the vast majority of insured Americans, Tenivac, Adacel, and Boostrix are available at no cost. This is because these vaccines are on the ACIP recommended immunization schedule, and several federal laws mandate their coverage.

Insurance Coverage Rules for Td and Tdap Vaccines

Understanding the coverage rules helps you counsel patients effectively and reduces billing surprises:

ACA-compliant private insurance: Under the Affordable Care Act, all marketplace-compliant health plans must cover ACIP-recommended vaccines at no cost-sharing (no copay, no deductible) when administered by an in-network provider. This applies to Tenivac, Adacel, and Boostrix. Patients should verify that the administering provider is in-network.
Medicare Part B: Medicare Part B covers the tetanus vaccine when related to the treatment of an injury or direct exposure (e.g., wound management). Under Part B, there is typically no copay and the deductible does not apply for this preventive service. If administered for wound prophylaxis in an office or ER setting, Part B is the appropriate payer.
Medicare Part D: Routine Td and Tdap boosters (not related to wound care) are covered under Medicare Part D plans at $0 cost-sharing for ACIP-recommended vaccines — a rule that has been in effect since 2023 legislation. All Part D plans are required to cover ACIP-recommended adult vaccines with no copay and no deductible.
Medicaid: Since October 2023, Medicaid and CHIP are required to cover all ACIP-recommended adult vaccines at no cost to beneficiaries. This includes Tenivac, Adacel, and Boostrix. Coverage applies in all 50 states.
VA and TRICARE: Veterans and active military typically receive all recommended immunizations at no cost through VA healthcare or TRICARE programs.

When Might Patients Still Have a Cost?

Several scenarios can result in unexpected out-of-pocket costs that providers should anticipate and help patients avoid:

Out-of-network administration: If a patient receives a vaccine from an out-of-network provider, cost-sharing rules may apply even under ACA plans. Counsel patients to confirm network status before scheduling.
Grandfathered health plans: A small number of employer plans are "grandfathered" under the ACA and not required to cover preventive vaccines at no cost. Patients with these plans may face copays.
Administration fee billing errors: Sometimes, even when the vaccine itself is covered at no cost, a separate administration fee is incorrectly billed to the patient. Remind patients that the administration fee should also be covered at no cost for preventive vaccines under ACA, Medicare, and Medicaid.
Uninsured patients: Patients without insurance will pay cash price, which ranges from approximately $50–$100 for Tenivac, Adacel, or Boostrix at retail pharmacies.

Resources for Uninsured Patients

For patients without coverage, direct them to these resources:

Local health departments: County and city health departments offer vaccines at no or low cost through public-sector supply programs. This is often the most cost-effective option for uninsured patients.
Federally Qualified Health Centers (FQHCs): FQHCs provide services on a sliding-fee scale based on income, including vaccinations. Find the nearest FQHC at findahealthcenter.hrsa.gov.
GoodRx and discount cards: GoodRx, SingleCare, and similar discount programs can reduce the retail cash price of Td/Tdap vaccines significantly — sometimes to $30–$55. Advise patients to compare prices at local pharmacies using goodrx.com before paying full retail.
Pharmaceutical company assistance: Sanofi Patient Connection and GSK for You programs can be checked for any vaccine-specific assistance programs. As vaccines are generally covered by insurance and government programs, manufacturer PAPs for vaccines are less common but worth checking.

Vaccines for Children (VFC) Program

For pediatric and adolescent patients (ages 7–18) who are uninsured, underinsured, or Medicaid-eligible, the CDC's Vaccines for Children (VFC) program provides all ACIP-recommended vaccines at no cost through enrolled providers. Td and Tdap vaccines are included. Practices enrolled in VFC can administer these vaccines at no cost to eligible children. If your practice is not VFC-enrolled, direct eligible families to a VFC-enrolled provider, such as a health department or FQHC.

Billing Guidance: Vaccine Administration Codes

From a billing perspective, correct coding helps ensure smooth coverage for patients. Relevant CPT codes include:

Tenivac (Td vaccine): CPT 90714 for vaccine product; 90471 for administration
Adacel or Boostrix (Tdap): CPT 90715 for vaccine product; 90471 for administration
For Medicare wound management cases: bill under Part B with appropriate diagnosis codes (tetanus prophylaxis related to wound)

Accurate coding not only ensures your practice is reimbursed correctly but also protects patients from surprise bills for covered preventive services.

Frequently Asked Questions

Yes, for most insured patients. ACA-compliant private insurance plans, Medicare Part D (routine boosters), Medicare Part B (wound-related tetanus), and Medicaid all cover Tenivac, Adacel, and Boostrix at no cost for eligible patients. Coverage applies when received from an in-network provider. Patients should confirm network status before their appointment to avoid unexpected bills.

Direct uninsured or underinsured patients to their local county health department (often provides vaccines at low or no cost through public supply), Federally Qualified Health Centers (FQHCs, sliding-fee scale), or discount cards like GoodRx which can reduce retail cost to $30–$55. Children 7–18 who are uninsured, underinsured, or on Medicaid may qualify for no-cost vaccines through the CDC's Vaccines for Children (VFC) program.

Under the ACA, both the vaccine cost and the administration fee for preventive ACIP-recommended vaccines should be covered at no cost-sharing for in-network providers. The same applies under Medicare Part D. However, billing errors can occur. If a patient receives an unexpected bill that includes an administration fee, advise them to call their insurance plan and reference the ACA's preventive care coverage mandate — the fee should be covered.

For Tenivac (Td): CPT 90714 for the vaccine product and 90471 for vaccine administration. For Adacel or Boostrix (Tdap): CPT 90715 for the vaccine product and 90471 for administration. For additional vaccines given at the same visit, use 90472 for each subsequent administration. Always use appropriate diagnosis codes (preventive medicine or wound management) to ensure correct payer determination.

Yes. Medicare Part B covers tetanus vaccination when it is directly related to the treatment of an injury or wound (e.g., wound management in your office or an emergency department). There is no copay and the Part B deductible does not apply for this preventive service when correctly billed. Routine Td/Tdap boosters (not wound-related) are covered under Medicare Part D at $0 cost-sharing.
