COVID-19 vaccines and their administration will be paid the same way influenza and pneumococcal vaccines and their administration are paid in FQHCs. Influenza and pneumococcal vaccines and their administration are paid at 100 percent of reasonable cost through the cost report. For a face-to-face encounter with administration on same day, the FQHC should bill for the cost of the COVID-19 or mAb administration to the encounter charge on the bill; reporting of these codes is informational only and reimbursement is made at the time of cost settlement. When COVID-19 vaccine and mAb doses are provided by the government without charge, only bill the vaccine administration, do not include the vaccine on the claim when the vaccines are free (do not show a 0.00 on claim).
Independent and provider-based RHCs do not include charges for vaccine or administration for COVID-19 or mAb on a claim, reimbursement is made at the time of cost settlement. Claims will process with $0 payment when submitted with only the vaccine and/or administration.

For patients in a Part A-covered SNF stay, CMS exercised “enforcement discretion,” which allowed Medicare-enrolled immunizers, including but not limited to pharmacies working with the United States, to bill directly and receive direct payment from the Medicare program for vaccinating Medicare SNF residents.
The enforcement discretion associated with vaccinating Medicare SNF residents ended on June 30, 2023, meaning that immunizers are no longer be able to bill Medicare directly for vaccines furnished to patients for a Medicare Part A-covered SNF stay. Beginning on July 1 ,2023, typical SNF consolidated billing regulations are in place, which require SNFs to bill for all services furnished to patients in a Medicare-covered SNF stay, including vaccines.
