The health insurance situation in Texas is anemic.

Last year, 17.7 percent of Texans lacked health insurance, according to newly released data from the U.S. Census Bureau. That's the highest rate of uninsured residents among all of the states.

The problem is even more acute in the Houston metro area. In 2018, nearly 1 in 5 residents of the region (18.6 percent) had no health insurance, the Census Bureau says. That's the highest rate of uninsured residents among the country's 25 most populous metro areas.

If you do the math, that translates into more than 5 million residents of Texas, including more than 1.3 million in the Houston area, who have no health-insurance safety net. A startup called Sidecar Health is setting out to reduce those numbers.

Texas recently became the first market for Sidecar Health's insurance plans, which it promotes as being "personalized" and "affordable." By the end of this year, the El Segundo, California-based company hopes to enroll at least 5,000 Texans.

Just as with subscription services like Netflix and Amazon Prime, a consumer can sign up for or cancel their Sidecar Health plan at any time. A member can lock in their Sidecar Health rate for three years.

Technically, Sidecar Health isn't an insurance company. Rather, it manages the insurance plans that it sells.

"Sidecar Health is different from traditional insurance in that we pay a fixed amount for any medically necessary service or prescription drug that you buy," the company explains on its website. "That means if your provider charges more than that fixed amount, you pay the difference. And if your provider charges less, you keep the difference."

Through Sidecar Health, a consumer can visit any healthcare provider, healthcare facility, or pharmacy they choose, as long as self-paying patients with credit cards or debit cards are accepted. This setup allows "complete transparency and control over healthcare costs," says Patrick Quigley, the startup's CEO.

"We make this possible by enabling our members to pay for care when they get it using the Sidecar Health payment card. Because doctors get paid immediately, they offer huge discounts. On average, it is 33 percent or more cheaper than what they charge big insurance companies," Quigley tells InnovationMap. "And because our members are doing the buying by swiping the card, they know what things cost. So you get true transparency and affordability — the way health insurance should be."

Through the Sidecar Health app, a member can see how much healthcare providers in their area charge, enabling them to compare prices.

"Our approach results in a truly affordable option for the millions of people left behind by the traditional model — those who don't qualify for a government subsidy but can't afford the cost of traditional plans," Quigley says in a release.

Sidecar Health is operating throughout Texas without any employees or offices in the state. The company sells its product directly through its website. On the website, consumers can educate themselves on available insurance plans before signing up online. Its Texas insurance plans are underwritten by Eatontown, New Jersey-based United States Fire Insurance Co., part of insurance conglomerate Crum & Forster.

Since its founding in 2018, Sidecar Health has raised $18 million in funding, led by San Francisco-based GreatPoint Ventures and Los Angeles-based Morpheus Ventures.

The startup's offering "is a great example of taking an otherwise complex process and making it simple, which is why Sidecar Health is such a game changer in health insurance," says Joseph Miller, managing partner of Morpheus Ventures.
