All antigens in a vaccine that prevent disease caused by one organism. Multivalent antigens or multiple serotypes of antigens against a single organism are considered a single component of vaccines. Combination vaccines are those vaccines that contain multiple vaccine components.Image result for immunization coding


For administration of a vaccine six CPT can be designated. These codes are depend on counseling provided in same visit or not.

Administration with Counseling

90460 : Through 18 years via any route with counseling by physician or other qualified health care professional; first vaccine/toxoid component. 

+90461 : Through 18 years via any route, with counseling by physician or other qualified health care professional; each additional vaccine/toxoid component. 

Administration without Counseling

90471 : Immunization administration (including percutaneous, subcutaneous, intramuscular, or jet injections); one vaccine (single or combination vaccine/toxoid)
90472 : each additional vaccine (single or combination vaccine/toxoid)
(Use code 90472 in conjunction with 90471.)

For administration of one component of a vaccine we can use 90460 and more than one component use 90461  (seperately for each component).

Whereas 90471 – 90474 use per vaccine rather than per vaccine componant.


  • Human Pappiliomavirus vaccine includes single component : (90460)
  • DTaP- Hemophillus influenza type b (90460, +90461*3 ) vaccine includes four components.

Route of administration is also a important factor for proper coding of an admin code.

  • 90471-90472 for percutaneous, intradermal, subcutaneous or intramuscular injection.

Example: Physician has given 2 intramuscular, 1 oral and 1 intranasal injection to a 40 years old patient. Condition should be coded as:

  • 90471
  • 90472
  • 90474*2

  • 90700: DTaP vaccine im
