The Santa Clara County Board of Supervisors unanimously passed a vote Tuesday to expand healthcare coverage for low- and middle-income families.

The Board agreed to subsidize 100 percent of healthcare costs for families of four making up to $105,000 per year, or individuals making up to $51,000 per year. This program applies to those who are receiving medical services at Valley Medical Center hospitals and clinics.

The program will also subsidize healthcare costs for families making between $105,000 to $170,000 on a sliding scale of 25 to 70 percent.

According to County Supervisor Joe Simitian, approximately 100,000 Santa Clara County residents are uninsured, with the possibility of 20,000 residents being covered under this plan.

"Every man, woman and child in this County should get the health care they need," Simitian said in a press release. "It’s the right thing to do, and it’s the smart thing to do."

The County's new program is designed to improve healthcare access and specifically targets people who lack health insurance but don't qualify for Medi-Cal or Medi-Care and can't afford the going rate for health insurance. Simitian added that the program is meant to provide coverage for those in the "missing middle" – those who are not eligible for health insurance or whose medical bills exceed 10 percent of their household income.
