Proposition 35 asks California voters to make permanent a tax on health insurance providers, also known as managed care organizations. The measure also sets rules around how the state uses the money collected from that tax. California has expanded those who are eligible for Medi-Cal, the state's Medicaid program. Healthcare providers have complained the state reimburses doctors, nurse practitioners and others too little for providing services to Medi-Cal patients. The measure requires the state to use the money collected from the tax to be used only to reimburse those Medi-Cal providers for primary, specialty and emergency care plus family planning, mental health and prescription drugs. Earlier this year, state lawmakers and the governor agreed to use funds from a temporary managed care organization tax to pay for some state healthcare costs broadly as California grappled with a budget deficit in the tens of billions of dollars. As a result, Medi-Cal provider reimbursement rates were not as high as some groups were expecting. The proposal would restrict the state's ability to do that in the future. The federal government would also be involved and would provide revenue to the state as a result of the tax. It would need to ultimately approve this as well. Who supports it?

Proposition 35 asks California voters to make permanent a tax on health insurance providers, also known as managed care organizations. The measure also sets rules around how the state uses the money collected from that tax.

California has expanded those who are eligible for Medi-Cal, the state's Medicaid program. Healthcare providers have complained the state reimburses doctors, nurse practitioners and others too little for providing services to Medi-Cal patients. The measure requires the state to use the money collected from the tax to be used only to reimburse those Medi-Cal providers for primary, specialty and emergency care plus family planning, mental health and prescription drugs.
