What Is CPT Code 90707 & How to Use It in MMR Vaccine Claims

If your practice gives the measles, mumps, and rubella (MMR) vaccine, you're billing CPT code 90707. The code itself is straightforward. The billing rules around it are not.

CPT 90707 is one of the most commonly billed vaccine product codes in pediatric and family medicine. Yet many claims are denied because the administration code isn't paired correctly, the wrong VFC modifier is used, or the documentation doesn't support the claim.

Know the 90707 CPT code description, administration code pairing, and VFC billing rules. 

What is CPT code 90707

CPT code 90707 is the vaccine product code for the measles, mumps, and rubella (MMR) vaccine, live, for subcutaneous use. It covers the vaccine itself, not the act of giving the injection.

That distinction trips people up constantly. CPT 90707 goes on the claim to represent the MMR vaccine product that was administered. The administration (the actual injection) is billed separately using a different code. We'll get to those pairing rules in the billing section below.

The two FDA-approved MMR vaccine products that bill under this code are MMR II (Merck) and Priorix (GSK). Both are live vaccines given subcutaneously, and both use the same CPT code. You don't need a different code based on the manufacturer. But you do need to document the specific product, lot number, and NDC on the claim. You can also review the HCPCS guidance for Priorix (MMR vaccine) and CPT 90707.

The standard ICD-10 diagnosis code paired with CPT 90707 is Z23 (encounter for immunization). If the vaccine is part of a well-child visit, Z23 goes in as a secondary code behind the preventive visit code (Z00.121 or Z00.129).

When should you use CPT 90707

Use CPT 90707 any time you administer the MMR vaccine as a standalone product. The most common scenarios include:

• Routine childhood immunizations (first dose at 12-15 months, second dose at 4-6 years per the ACIP schedule)

• Adult patients who lack documented MMR immunity (healthcare workers, college students, international travelers)

• Catch-up immunizations for patients who missed doses

• Outbreak response situations where public health authorities recommend additional doses

The code does not apply when you administer the MMRV combination vaccine (measles, mumps, rubella, and varicella together). That's a different product with a different code, which we'll compare below.

Does CPT 90707 have an age limit

The 90707 CPT code age limit question comes up a lot, and the answer depends on what you mean by limit.

CPT 90707 itself has no hard age restriction in the AMA code set. The code can be used for patients of any age who receive the MMR vaccine. You can bill it for a 13-month-old getting their first dose or a 45-year-old healthcare worker getting a booster.

Where age limits do appear is in payer policy and clinical guidelines. The ACIP recommends the first MMR dose at 12-15 months, so most payers won't cover a claim for 90707 before 12 months of age without a documented medical reason (like international travel during a measles outbreak). Some Medicaid programs explicitly state that the patient must be 12 months or older for covered administration.

For VFC-eligible patients, the age range is typically 12 months through 18 years of age. Infants younger than 12 months may qualify if they're traveling internationally or there's an active outbreak, but the claim needs documentation explaining why.

CPT 90707 works across all ages. The payer decides whether they'll cover it for a specific patient based on age, clinical indication, and their own coverage rules.

MMR Vaccine Product and Administration Codes

This is one of the most common coding mix-ups in vaccine billing. Using the wrong product code is a compliance issue, not just a billing error.

Code	What it reports	Main billing point
90707	MMR vaccine product	Covers measles, mumps, and rubella
90710	MMRV vaccine product	Also includes varicella
90460	First vaccine component with qualifying counseling	Used through age 18
90461	Each additional vaccine component	Add-on code to 90460
90471	First or only injectable vaccine administration	Used when pediatric counseling requirements are not met or for adults
90472	Each additional injectable vaccine	Add-on code to 90471

How to bill CPT 90707 correctly 

A clean MMR vaccine claim requires two separate codes: one for the vaccine product and another for administering it. Missing either one can delay payment or lead to a denied claim.

Step 1: Bill the vaccine product

Start with CPT code 90707, which reports the MMR vaccine product (measles, mumps, and rubella). This code identifies the vaccine that was supplied to the patient. It does not include the work of administering the injection.

Step 2: Add the correct administration code

After reporting CPT code 90707, choose the appropriate administration code based on the patient's age and whether face-to-face vaccine counseling was provided and documented.

• 18 years and younger (with counseling): 90460 + 90461 for additional vaccine components. If you're unsure when to report these administration codes, see our guide on vaccine administration codes.

• Over 18 or no counseling: 90471 for the first vaccine and 90472 for additional vaccines given during the same visit.

Step 3: Avoid using the wrong vaccine product code

One of the most common billing mistakes is selecting the wrong vaccine code.

• 90707 – MMR vaccine (measles, mumps, and rubella)

• 90710 – MMRV vaccine (measles, mumps, rubella, and varicella)

• 90708 – Measles and rubella vaccine

• 90705 – Measles vaccine only

Always bill the code that matches the vaccine actually administered. Choosing the wrong product code can result in claim denials, payment issues, or compliance concerns.

Step 4: Link the diagnosis correctly

Most payers expect ICD-10 code Z23 (Encounter for immunization) to support the vaccine administration. Before submitting the claim, confirm that the diagnosis, vaccine product, and administration codes are linked correctly according to your payer's billing requirements.

How Does the VFC Program Affect CPT 90707 Billing

The Vaccines for Children (VFC) Program changes how CPT code 90707 billing works. When you administer a state-supplied MMR vaccine through VFC, you don't bill for the vaccine product. Instead, you bill only the vaccine administration according to your payer's VFC guidelines.

Most Medicaid programs require Modifier SL for VFC-supplied 90707 claims. Leaving it off or not following your state's VFC billing requirements can lead to claim denials. 

What documentation supports a 90707 claim

A complete record should show what vaccine was given, who administered it, when it was administered, and the information shared with the patient or parent. Good documentation not only supports payment but also helps during audits.

Your documentation should include:

• Vaccine name (MMR II or Priorix)

• Manufacturer and lot number

• Expiration date and NDC (if required)

• Date and time of administration

• Dose, route, and injection site

• Name and credentials of the person who administered the vaccine

• Vaccine Information Statement (VIS) edition date and the date it was provided

• Patient or guardian consent

• Counseling documentation when billing 90460 or 90461

• VFC eligibility and inventory source, when applicable

Simply documenting "VIS provided" may not support 90460 or 90461. The medical record should also show that a physician or other qualified healthcare professional provided and documented vaccine counseling on the same date.

Does CPT 90707 require a modifier

Under standard billing circumstances, CPT 90707 does not require a modifier. You submit the product code as-is on its own claim line.

However, several situations call for specific modifiers:

Modifier SL is required by many Medicaid programs when the vaccine was supplied through the VFC program. This tells the payer you're billing only for the administration fee, not the product cost. When SL is required and missing, the claim is denied.

Modifier SK (member of high-risk population) is used by some state Medicaid programs (California, for example) alongside SL for VFC claims.

Modifier 25 is reported with the E/M code, not CPT code 90707. If a separately identifiable evaluation and management service is provided on the same day as the immunization, append Modifier 25 to the E/M service. See more examples of Modifier 25 in pediatric billing and when it should be reported with an E/M service.

Modifier 59 may be needed in rare cases where a payer incorrectly bundles multiple vaccine administration codes. Use it deliberately, not as a default fix for every bundling denial.

Always check your payer-specific modifier requirements. What Medicaid requires in one state may differ from the next.
