MILWAUKEE (CBS 58) -- Ascension Wisconsin has notified patients that its doctors and hospitals may be considered out-of-network for UnitedHealthcare members starting Wednesday, Oct. 1 if a new contract is not reached.

The health system said it has been in negotiations with UnitedHealthcare for months, seeking what it called fair reimbursement rates. Ascension said UnitedHealthcare’s current proposal does not keep up with cost increases hospitals face, including inflation and rising equipment and medication prices.

If no agreement is made, Ascension Wisconsin facilities and doctors will no longer be covered as in-network for UnitedHealthcare Commercial plans. That could leave patients paying higher costs for care, according to Ascension.

In a letter dated Tuesday, Sept. 2, Ascension urged patients to call UnitedHealthcare, talk to their employer’s HR department or explore alternative plans during open enrollment to maintain access to its doctors.

For now, patients may continue visiting Ascension doctors and clinics as usual. More information can be found by clicking here.
