The CARES Act (H.R.748, enacted in March 2020) requires all non-grandfathered health plans, including private insurance, Medicare, and Medicaid, to cover COVID-19 vaccines without any cost-sharing for the member (the same caveats described above apply, however, as plans that aren’t regulated by the ACA are not included in the vaccine coverage requirement unless a state steps up and imposes its own requirement).
The full coverage of COVID-19 vaccines includes both the vaccine itself and any charges from the provider or facility for the administration of the vaccine. The COVID-19 vaccine has been added to the list of recommended vaccines, and the CARES Act required private health plans to begin fully covering it within 15 business days — much faster than the normal timeframe (which can be nearly two years, depending on the circumstances) between when a preventive care recommendation is made and when insurers have to cover it with no cost-sharing. This applies to all COVID vaccines that have received FDA approval, including emergency use authorizations. As of April 2021, that includes vaccines from Pfizer, Moderna, and Johnson & Johnson.
