Our top priority is providing people access to the care they need

People enrolled in a UnitedHealthcare employer-sponsored commercial or IFP plan who were in active or ongoing treatment for a serious or complex condition with a Corewell Health Farmington Hills Hospital employed provider or at one of the four Corewell Health hospitals now out of network may be eligible for continuity of care.

Continuity of care provides continued in-network benefits for a specified period of time after a hospital leaves our network. A few examples of patients who may qualify include:

  • Women who are pregnant
  • Patients with newly diagnosed or relapsed cancer, or those currently in active cancer treatment.

Members who have questions about continuity of care or alternative hospitals in their area should call the number on their health plan ID card. Members can also use the provider directory on our member website to search for alternative hospitals and doctors.

In the event of an emergency, UnitedHealthcare members should go to the nearest hospital and will be covered at the in-network benefit level, regardless of whether the hospital participates in our network.

Facts you should know

Corewell is seeking unreasonable price hikes that are not affordable and would increase health care costs for consumers and employers in Michigan

Excessive rate demands have an impact on the cost of premiums as well as out-of-pocket costs for the people we serve, while also driving up the cost to do business for employers.

We have a responsibility to provide the people we serve with access to quality health care while also helping to contain rapidly rising health care costs.

We are committed to engaging in productive, good-faith negotiation and urge Corewell to provide a proposal that is reasonable and affordable.

We are proposing rates that will continue to reimburse Corewell fairly and similarly to its peers while slowing the unsustainable rise in health care costs

Maintaining fair and competitive agreements with the providers in our network is critical to our ability to meet this commitment to our members and customers.

We are hopeful that Corewell will work with us to reach an agreement that is affordable for families and customers in Michigan.

We remain open and committed to working with Corewell with the goal of reaching an agreement

We are actively engaged in ongoing discussions with Corewell.

We will remain at the negotiating table as long as it takes. We hope Corewell will join us there and work toward an agreement consumers and employers in Michigan can afford.
