Use Code

What is CPT 90460?

CPT code 90460 refers to immunization administration for patients 18 years of age or younger, provided by a physician or other qualified health care professional. It includes counseling of the patient and/or guardian.

This code covers each of the first or only vaccine/toxoid components administered per day. It also encompasses both the physical act of administering the immunization via any route - intramuscular, subcutaneous, intradermal, etc - and the face-to-face counseling provided. This can also be a form of preventive health care service that involves an educational discussion regarding the vaccine's risks, benefits, and potential side effects, and is documented.

Do note that for combination vaccines, only 90460 is reported for the first component, and additional administration codes are used if the vaccine contains multiple components, such as CPT code 90461. To add any other evaluation and management service, use a modifier.

The name, manufacturer, and lot number of the vaccine
The date when the vaccine is administered
The site, method, and route of administration

Detailed documentation of vaccine counseling is provided, especially for combination vaccines

Frequently asked questions

The primary diagnosis code is typically Z23 (Encounter for immunization). However, if the immunization is given for a specific reason (e.g., rabies vaccine after an animal bite), the code for the exposure would be the primary diagnosis, with Z23 as a secondary code.

Generally, modifier -51 is not appended to the add-on code +90461. Modifier -25 may be appended to an evaluation and management (E/M) code if a significant, separately identifiable E/M service is also performed and documented. Other modifiers might be necessary depending on specific circumstances and payor rules.

Yes, you can bill 90460 for the first or only component of each single-component vaccine administered, provided that counseling is given for each vaccine. For example, if you give a flu shot and a tetanus shot, and provide counseling for both, you would bill 90460 twice.
