What 90471 covers

90471 represents administration of one vaccine by percutaneous, intradermal, subcutaneous, or intramuscular route. It applies to an injectable vaccine product whether the product contains one antigen or is a combination vaccine or toxoid; report the vaccine product separately. Physicians and clinical staff commonly provide this service in physician offices and outpatient settings.

Report one unit for one vaccine administration. When additional injectable vaccines are administered in the same encounter, report 90472 for each additional administration. Select the administration code by route and applicable counseling criteria, not just by the vaccine’s name. Documentation should identify the vaccine, route, date, and administering clinician. Under the CMS incident-to rule, the service may be billed only when performed under physician supervision.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

90471 billing questions

When should 90471 be reported instead of 90460?

Use 90471 for an injectable vaccine when the criteria for the counseling-based code are not met. Code 90460 applies to patients 18 or younger when a physician or other qualified health care professional provides counseling about the vaccine.

Is the vaccine product included in 90471?

No. 90471 reports the administration service; report the vaccine product separately.

Can 90471 and 90472 be reported together?

Yes. Report 90471 for one injectable vaccine administration and 90472 for each additional injectable vaccine administered in the same encounter.

Does 90471 cover oral or intranasal vaccines?

No. For an oral or intranasal vaccine administration, use 90473 for one vaccine; 90474 is the add-on code for each additional oral or intranasal vaccine.

Can clinical staff perform the service?

Yes, but under the CMS incident-to rule, 90471 may be billed only when the service is performed under physician supervision.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
