Proposition 55 (2016) aimed to increase funding for Medi-Cal under a formula administered by the Department of Finance. In 2018-19, the first year of implementation of this calculation, the administration’s interpretations and estimates result in no additional funds to Medi-Cal. Two key choices lead to this result. First, the administration’s decision to subtract $3.5 billion from available revenues to account for its proposed optional reserve deposit significantly reduces the calculation’s starting point, eliminating a surplus that would have directed funds to Medi-Cal. Second, the administration’s workload budget approach is based on a broad definition of currently authorized services, which also has the effect of reducing the amount of potential funds for Medi-Cal under the measure. Different decisions about these two features of the measure could result in more or less funding for Medi-Cal by hundreds of millions—or even billions—of dollars in the future.
