Summary
IHCP has updated Novavax COVID-19 vaccination billing guidance, discontinuing old administration codes (0041A, 0042A, 0044A) and requiring use of universal administration code 90480 for all Novavax COVID-19 vaccines administered on or after November 1, 2023. The vaccine product code 91304 remains the same but now covers the updated 2023-2024 formula.
Action Required
Immediately: Update billing system to use CPT code 90480 for all Novavax COVID-19 vaccine administration instead of discontinued codes 0041A, 0042A, and 0044A for dates of service on or after November 1, 2023. Continue using CPT 91304 for the vaccine product. Remove old administration codes from encounter forms and billing software. Note that members ages 12-18 years reimburse at $0 due to VFC availability.
