California’s taxpayer-funded health care rolls have grown substantially in the last three years and if President Obama’s executive amnesty order stands, they’re poised to grow even more.

According to the UC Berkeley Labor Center:

Between 360,000 and 500,000 immigrants living in California would become eligible for Medi-Cal if they receive temporary protection from deportation and permission to work as a result of recent executive actions by President Barack Obama. Up to 57 percent of immigrants in California who are eligible under the executive actions are low income and lack private health insurance, according to a study by UC Berkeley’s Center for Labor Research and Education and the UCLA Center for Health Policy Research.

In November, Obama announced the expansion of the Deferred Action for Childhood Arrivals program, or DACA, which was established in 2012, and the creation of Deferred Action for Parents of U.S. Citizens and Lawful Permanent Residents, or DAPA. Applications continue for the original DACA program. Application processes for the new programs have been placed on hold under a court order, but immigration policy experts predict that the new programs will ultimately be implemented.

According to the Center, illegals are not eligible for coverage under Obamacare, but qualify for Medi-Cal under California state policy.

“We have left behind millions of undocumented workers and students who are excluded from health coverage options under the Affordable Care Act,” says Laurel Lucia, a policy analyst at the Labor Center.

“California is leading among states by providing comprehensive health care services to low-income residents granted DACA and DAPA, which is an important step toward closing the state’s largest eligibility gap.”

The Los Angeles Times reports the program as it is today costs the state $18 billion per year and covers about one-third of the state’s population.

The Labor Center estimates by 2019, about 44% of the state’s insured will be illegal immigrants — about 1.5 million people.

Despite being unsure how to pay for hundreds of thousands of potential new enrollees, state leaders don’t seem too concerned.

“There’s just a lot of work that’s still left,” says Democrat state Sen. Ed Hernandez , who adds he wants to make sure that existing Medi-Cal enrollees can quickly and conveniently get health care.
