CPT code 90619 – Meningococcal ACWY conjugate vaccine, tetanus toxoid carrier

Key takeaways

CPT code 90619 covers one product, MenQuadfi, the MenACWY vaccine built on a tetanus toxoid carrier. Menactra and Menveo bill under 90734 instead.

Always bill a separate administration code, such as 90471 or 90460, alongside 90619. The vaccine product code never covers the injection itself.

List Z23 first on every 90619 claim, and add a risk code such as D84.1 only to support medical necessity.

Most state Medicaid programs require modifier SL when the dose comes from Vaccines for Children (VFC) stock. Commercial payers should not receive it.

Pabau’s claims management software scrubs each claim for missing or invalid details, which helps catch vaccine coding errors before submission.

CPT code 90619: Official descriptor and quick-reference data

CPT code 90619 describes a quadrivalent meningococcal conjugate vaccine for serogroups A, C, Y and W-135, given by intramuscular injection. Its carrier protein is tetanus toxoid, which is why the descriptor ends in MenACWY-TT. The American Medical Association maintains this code within the Vaccines, Toxoids subsection of the Medicine section of the CPT code set. Each unit reports one dose of MenQuadfi, billed with a separate administration code.

MenQuadfi (Sanofi) is the only vaccine that maps to 90619. Menactra (diphtheria toxoid carrier) and Menveo (CRM197 carrier) cover the same four serogroups, but both bill under 90734.

What CPT code 90619 covers and excludes

90619 is limited to the MenACWY vaccine conjugated to tetanus toxoid. Several closely related meningococcal codes fall outside its scope.

• Included: The quadrivalent conjugate vaccine for serogroups A, C, Y and W-135, given intramuscularly with a tetanus toxoid carrier (MenQuadfi).
• Excluded (90734): MenACWY vaccines with a diphtheria toxoid carrier (Menactra) or a CRM197 carrier (Menveo). They cover the same four serogroups with a different carrier protein.
• Excluded (90620 and 90621): The serogroup B vaccines, Bexsero (MenB-4C, 90620) and Trumenba (MenB-FHbp, 90621). They target a different serogroup entirely.
• Excluded (90623 and 90624): The combined MenABCWY vaccines, Penbraya and Penmenvy, which add serogroup B to the ACWY antigens in one product.
• Excluded (90733): The meningococcal polysaccharide vaccine (MPSV4, Menomune), a non-conjugate formulation given subcutaneously.
• VFC supply note: Modifier SL is required by most state Medicaid programs when Vaccines for Children (VFC) public stock is used. The code itself does not change, and the modifier signals the supply source to Medicaid.

How CPT code 90619 differs from 90734 and other meningococcal codes

Meningococcal vaccine codes are easy to confuse, because several products cover the same serogroups. The table below shows what separates each code, so coders can pick the right one at the point of service.

Both 90619 and 90734 cover A, C, Y and W-135, so the carrier protein decides between them. In practice, the brand settles it: MenQuadfi goes to 90619, while Menactra and Menveo go to 90734.

Codes 90620 and 90621 are the serogroup B codes, and patients often get one of them at the same visit. Checking the brand and lot number against the package insert is the fastest way to pick the right code, in the order shown below.

Vaccine administration codes to bill with CPT code 90619

CPT code 90619 is the vaccine product code only. Billing it without a separate administration code leaves the injection service uncompensated and the claim incomplete. The correct administration code depends on patient age and whether counseling was documented.

90460 requires documented face-to-face counseling by the physician or other QHP, per AMA CPT guidelines. If counseling cannot be documented to that standard, 90471 is the correct choice regardless of patient age.

ICD-10 codes to report with CPT code 90619

Z23 is the primary ICD-10-CM diagnosis code for any vaccine administration visit, including 90619. It describes an encounter for immunization, and most payers accept it as the sole diagnosis for routine preventive vaccination. Use the CDC/NCHS ICD-10-CM web tool to confirm current-year code validity.

Modifiers for CPT code 90619

Modifier selection for CPT code 90619 depends on the vaccine supply source and the clinical scenario. Using the wrong modifier, or leaving off a required one, is a common cause of Medicaid denials for this code.

SL is a Medicaid-specific modifier. Commercial payers do not recognize it and should receive claims without SL even when the dose came from VFC stock. Always confirm modifier requirements with the specific payer before submitting.

2026 reimbursement rates for CPT code 90619

CPT code 90619 reimbursement reflects vaccine acquisition cost plus a dispensing or handling component rather than a work RVU-based rate. The CMS Physician Fee Schedule lookup tool provides the current national allowable for 90619 under Medicare. Use that tool directly rather than relying on third-party aggregator figures, which may lag behind annual updates.

• Medicare: 90619 is typically reimbursed at a pass-through rate tied to the vaccine’s average sales price (ASP) plus a percentage markup. The exact 2026 allowable is published in the CMS Physician Fee Schedule and varies by Medicare Administrative Contractor (MAC) region.
• Medicaid: State Medicaid programs set their own fee schedules. Some state Medicaid programs set age limits for 90619, so check your state’s current policy and fee schedule portal before billing.
• Commercial payers: Rates are contract-specific. Vaccine product codes are often reimbursed at ASP plus a negotiated markup, separate from the E/M or administration allowable.
• VFC doses: When billed with modifier SL, Medicaid programs reimburse the administration fee only. The vaccine product line (90619 with SL) is typically paid at $0 for the product component.

Documentation requirements for CPT code 90619

Missing or incomplete records are a frequent audit finding for vaccine codes. The medical record must support every element of the 90619 claim at the time of service, not after a denial.

• Vaccine name, lot number, and expiration date: Required in the chart note. Auditors match the lot number to the VFC order record when modifier SL is present.
• Route and injection site: Document “IM, deltoid” or the specific anatomical site. Route must match the code descriptor (intramuscular).
• VIS delivery: Record that the patient or guardian received the Vaccine Information Statement before the injection. Note the VIS edition date and the date it was given.
• Patient or guardian consent: Record written consent, or documented verbal consent, before the injection.
• Counseling documentation (if billing 90460): Note must reflect face-to-face counseling by the physician or QHP, not just nursing staff delivery. Time is not required, but the provider identity and counseling content must be documented.
• VFC eligibility screening (if billing SL): Screen the patient using the VFC eligibility criteria at each visit and document the result. A signed VFC eligibility screening form satisfies most Medicaid audit requests.

Maintaining medical billing compliance for vaccine codes depends on building these steps into the visit itself. They belong in the chart before the patient leaves the room, not in a post-visit charting session.

Common claim denials for CPT code 90619 and how to avoid them

Vaccine code denials cluster around five error patterns. Each has a straightforward fix when caught before submission.

Clean claim submission workflows that validate modifier and code pairings help catch many of these errors before submission. The AAPC CPT code lookup provides modifier guidance and bundling edits for the 90619 code family when manual verification is needed. Once a denial arrives, the denial codes guide helps staff trace each claim adjustment reason code (CARC) to the error behind it.

How Pabau supports meningococcal vaccine billing

Many practices still pick vaccine codes from memory and add modifiers after the visit. That is how a MenQuadfi dose ends up billed as 90734, or a VFC dose goes out without modifier SL.

Pabau, our practice management and billing platform, keeps that check inside the visit. Its claims software built for practices includes claim validation, which scrubs each claim for missing or invalid details before submission.

Claim.MD handles eligibility checks and electronic submission. Through it, practices send 90619 claims to thousands of US payers and track remittances through electronic remittance advice (ERA).

That helps catch many of these errors before submission, so your team spends less time reworking meningococcal claims.

Conclusion

CPT code 90619 belongs to one vaccine, MenQuadfi, and many coding errors start when it is confused with 90734. Get the brand right first. The administration code, Z23 as the first diagnosis and SL on Medicaid VFC doses then follow from the visit record.

Practices that give meningococcal vaccines every week gain the most from checking codes and modifiers before a claim leaves the building. Fixing a claim at that point costs minutes, while fixing it after a denial costs weeks.
