Our Purpose

Live Life To The Healthiest

We believe that the health insurance industry should do far more than just provide access to doctors and cover or administer claims. The way we see it, health care plans should help people live healthier. Which is exactly what makes us different. As a health plan management and administrative services company, we’re leading the charge on everything from expanding network physician and provider options to creating innovative approaches to wellness, prevention and community well-being. That’s because at Quartz, we’re a company committed to good health.

About Us

Creating Quartz

Quartz is the result of the forward-thinking integration of Gundersen Health Plan and Unity Health Insurance – two organizations aligning their business needs in order to better serve members. Quartz will be responsible for managing these two nationally recognized, provider-sponsored health plans, with the primary goal of making sure that the local communities they serve have access to innovative, high-quality and affordable health care. Quartz also is a third-party administrator of self-funded health plans.

Gundersen Health Plan & Unity Members

If you are currently a member of either Gundersen Health Plan (Gundersen) or Unity Health Insurance (Unity) – rest easy. We do not foresee any changes that will affect your health plan or your health care providers. *In fact, the partnership between Gundersen and Unity means that, depending on your health plan, members have access to a wider range of care providers – including Gundersen Health System in the La Crosse area and UW Health in Madison, Dane County and surrounding areas. While the introduction of Quartz should feel seamless to you, we’re happy to answer any related questions that you may have. Contact us.

State & Local Government Employees

As many of you are aware, the department of Employee Trust Funds considered structural changes to the State of Wisconsin Group Health Insurance Program – moving from a traditional health insurance selection model to a self-funded model. The Group Insurance Board awarded Quartz a contract as a self-funded vendor in the Southern Region. This means if the new structure is approved and we finalize a contract, you should select Quartz during the 2018 open enrollment. While the proposal to self-fund is still being decided, we think it’s important to keep you informed.

More Programs.
Expanded Services.
Larger Network.

Philosophy. Imagine a future where health plans are equally as committed to creating wellness programs as they are to expanding provider networks – as committed to community health as they are to the customer experience. A time when health plans are designed, supported and managed by people who truly care about making every community they touch not only healthier, but also happier. We believe that day is today. At Quartz, we believe that the health plans we manage and administer can be an integral part of advancing and bettering humankind. This is our vision for the future.

Local Decision making.
Broader network access.

Thanks to this partnership, we now have access to an even larger provider network. This means that certain plans will offer access, not only to local physicians throughout the UW Health and Gundersen Health System areas, but also to specialty care at Gundersen Health System, UW Health’s American Family Children’s Hospital and UW Health’s University Hospital – rated best in Wisconsin by U.S. News and World Report*. More importantly, as compared to others in the market, Quartz is a local company – making all of its decisions with your doctor’s input and in your own backyard.

*According to 2016-2017 edition of the Best Hospitals guide by U.S. News & World Report.

LIVE LIFE LIKE YOU MEAN IT. Here’s to living large each and every day. To chasing your passions and following your dreams – no matter where they decide to take you. Here’s to taking a moment and thinking about your health – to making a commitment to health and happiness.
