A Group Health Cooperative of Eau Claire health plan in partnership with Common Ground Healthcare Cooperative.

Common Ground Healthcare Cooperative (CGHC) is a non-profit insurance cooperative which serves the people of Wisconsin and gives the public a voice in their health insurance. In many ways, cooperatives behave much like any other health insurance company. We meet the same laws and regulations, and we provide medical insurance and prescription drug coverage. What makes us different is that we answer to our members, not corporate shareholders, so we have absolutely no motivation to raise prices simply to make more money. We are pleased to provide coverage throughout Eastern Wisconsin with high quality care at lower costs.

What’s New for 2023

The Cooperative continues to urge members to utilize our telehealth service, Teladoc. Teladoc provides access to a doctor through the convenience of a phone or video consult for treatment of many minor conditions, such as cold and flu symptoms, from the comfort of your home. If necessary, you can even receive a prescription. Visit for more information.

In 2023 CGHC is excited to provide coverage in the following counties throughout Eastern Wisconsin: Brown, Fond du Lac, Green Lake, Kewaunee, Manitowoc, Marinette, Milwaukee, Outagamie, Ozaukee, Shawano, Sheboygan, Washington, Waukesha, Waupaca, Waushara, and Winnebago.

Referrals, Authorizations, Out-of-Network

Referrals are not needed when receiving care from in-network providers. All out-of-network requests require an approved referral by CGHC. Certain in-network services and all admissions require a prior authorization as well. You will receive written notification of the approval or denial for the prior authorization. Members with low back pain are required to participate in a shared decision-making tool to review information on options, outcomes, and to clarify personal values. For further information regarding authorization guidelines, please visit our partner’s website at or call 1-888-203-7770 to speak with Member Services.

Emergency and Urgent Care

If you require emergency or urgent care while outside the network, seek care at the nearest medical facility. Use the Teladoc number listed on your ID card if assistance is needed to determine the appropriate level of care. Follow-up care must be received from an in-network provider unless otherwise authorized by the Cooperative.

Mental, Behavioral Health and Substance Abuse

No referral is needed to see a provider in the Cooperative’s network. Prior authorization guidelines may apply for certain services; please contact Member Services at 1-888-203-7770 for additional information.
