Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 90461 covers

Code 90461 represents administration of an additional vaccine component for a patient age 18 or younger when a physician or other qualified health care professional provides immunization counseling. It is commonly relevant when a combination vaccine contains multiple components. The code counts components, not injections, so a single injection can involve more than one reportable component. The physician or qualified health care professional may provide the service in an office, clinic, or other setting where pediatric immunizations are administered.

Report 90461 only with 90460, which represents the first component; use one unit of 90461 for each additional component. Documentation should support the patient's age, counseling by the physician or qualified professional, vaccine administered, and the component count. CMS classifies 90461 as an add-on code: it cannot be billed alone, and its payment is within the primary procedure's global period. Do not use it to count additional injections when the service is administration without the counseling framework.
