This research brief from the UCLA Center for Health Policy Research provides updated estimates of the number of Californians who are likely to obtain health insurance coverage through the implementation of the Patient Protection and Affordable Care Act.
The updated estimates are based on data from the 2009 California Health Interview Survey, which collects statewide data on health insurance coverage and family income that allows these updated projections. According to this analysis, over 3 million currently uninsured Californians would be newly eligible for the authorized expansion in Medicaid, which would cover all adults up to 133% of the Federal Poverty Level. Another 1.7 million currently uninsured Californians would use federal subsidies to purchase health insurance coverage through the state health insurance exchange (with incomes up to 400% of the Federal Poverty Level). And some 1.2 million currently uninsured Californians would also be able to purchase health insurance coverage through the state health insurance exchange, without federal subsidies.
