Madison Medical Back In-Network with UHC

We’re happy to share that Madison Medical Affiliates is once again in-network with all UnitedHealthcare insurance plans, effective October 1, 2025.

Ascension Wisconsin and UnitedHealthcare have finalized a new agreement that ensures continued access to in-network care for all UHC Commercial, Medicare, and Medicaid members. Any services received between October 1–13 will also be processed at in-network rates.

We are deeply grateful for your patience and understanding during this transition — and most of all, for the trust you place in us. It’s a privilege to care for you and your family, and we’re thrilled to welcome our UnitedHealthcare patients back with open arms.

As we work through this transition, please be patient with our team — we expect higher-than-usual call volumes over the next few days and will do our best to respond as quickly as possible.
