United Healthcare Contract Negotiations

Due to a contract dispute between UnitedHealthcare and Ascension Wisconsin, we understand many of our patients have questions and concerns. We want to reassure you and provide clarity regarding your care.

We are still in-network with UnitedHealthcare, and that contract remains in effect until October 1, 2025. Please note that even if you receive a letter from UnitedHealthcare stating otherwise, you are still covered for your appointments with us.

If you have an upcoming appointment, please do not cancel it at this time. We are closely monitoring the negotiations and will provide updates as soon as they become available. Our goal is to ensure you continue to receive the care you need with as little disruption as possible.

For more information, you can visit the official negotiation pages for each organization:

We appreciate your patience and will keep you informed of any changes.
