Medicare Part A and B Billing for the COVID-19 Vaccine and Monoclonal Antibody

With the end of the PHE, as of 5/11/2023, this information no longer applies. We will keep the information available for PHE-related services that occurred prior to the expiration date that have not yet been billed.

Medicare providers may bill immunizations, including COVID-19 vaccine administration, as a single claim per patient or on a roster bill for multiple patients.

COVID-19 vaccine and monoclonal antibody doses provided by the government, without charge, cannot be billed on Medicare claims. Only include the vaccine administration code on the claim when the vaccines are free

Roster Billing

If you use roster billing, you must administer the same type of shot to five or more people on the same date of service.

The Vaccine Roster Form must include the following details, and must include a modified CMS-1500 claim form or CMS-1450 claim form; as a roster cover document for each facility where the services are rendered:

  • Patients name, address, Medicare number, date of birth and gender
  • Date of service
  • Beneficiary signature or stamped “Signature on File”
  • Providers name and identification number
  • Control number for contractor

How to Submit a Centralized Bill

Centralized billing allows mass immunizers to send all roster bill claims for flu, pneumococcal, and COVID-19 vaccinations to a single MAC, Novitas, for payment, regardless of where you administer the shots.

Medicare makes geographic payment adjustments based on the locality where you administer the shot. You must submit all centralized biller claims as professional claims on a roster bill.

  • You must operate in at least three MAC Jurisdictions.
  • You can refer to the Who are the MACs web page on the CMS website.

Medicare Advantage Plan Enrolled Beneficiaries

For claims with dates of service on or after 1/1/2022, please submit COVID vaccination claims to the Medicare Advantage (MA) plan that your patient is enrolled with.

For claims with dates of service in calendar years 2020 and 2021, the COVID vaccination claim is submitted to your A/B MAC when your patient is enrolled in a MA plan. Part A and Home Health and Hospice (HH+H) claims must include Condition Code 78.
