Your Doctors, Our Network

Our handy Find a Doctor tool will help you find primary care, specialists, health care facilities, and pharmacies within the Quartz Medicare Advantage provider network. The directory is updated daily, so you’ll always have access to the most current information.

For help finding a primary care provider at Gundersen Health Systems, call the New Patient Registration Dept. at (608) 775-0601.

Note: If you have a health care visit with an out-of-network provider, it could result in nonpayment of services. This means you would need to pay for your care or services.
