CPT® Code 90474

Add-On Code

Immunization administration by intranasal or oral route; each additional vaccine (single or combination vaccine/toxoid) (List separately in addition to code for primary procedure)

The CPT® Code 90474 refers to the administration of immunizations via intranasal or oral routes, specifically for each additional vaccine administered beyond the primary procedure. This code is applicable when a patient, regardless of age, receives a single vaccine or a combination vaccine/toxoid. It is important to note that this administration can occur with or without a face-to-face encounter with a healthcare professional. For patients over the age of 18, the administration may not require direct interaction with a physician or other healthcare provider. Additionally, this code is also relevant for patients aged 18 or younger when the vaccine/toxoid is given without the necessity of face-to-face counseling. To accurately report the immunization process, the primary vaccine administration is coded using 90473, while 90474 is designated for each subsequent vaccine/toxoid administered during the same visit. This structured approach ensures proper documentation and billing for immunization services provided to patients.
