The COVID-19 supplemental payment increase of up to 7.5% will fund efforts by CalOptima-contracted providers to promote and administer COVID-19 vaccinations, cover increased costs for testing and treatment, and help address additional variants of the COVID-19 virus. The payments will be made for a full year, from July 1, 2022, to June 30, 2023. The Board first approved supplemental payments in 2020 after recognizing the additional strain put on providers by the pandemic and the potential for interruption in necessary Medi-Cal services. This financial support also supports the health care safety net generally, given that CalOptima membership grew 23% during the pandemic to nearly 900,000.
