Ascension hospitals, clinics and employed doctors in Texas, Oklahoma and Kansas are on track to fall out of UnitedHealthcare’s networks on January 1, 2027, unless the two sides sign new contracts before the old ones run out. The hospital system has posted separate warnings for each state, and each one names the same cutoff.
The timing puts the dispute squarely inside Medicare’s fall enrollment season. People in UnitedHealthcare Medicare Advantage plans who rely on an Ascension hospital or doctor have until December 7 to change plans for next year, weeks before anyone will know whether a deal gets done.
Which Ascension systems and UnitedHealthcare plans are involved
In Texas, Ascension says its UnitedHealthcare contract expires January 1, 2027, and that if no new agreement is reached by December 31, every Ascension Texas location becomes out-of-network on January 1. That covers hospitals, clinics, outpatient facilities and employed doctors. The Texas notice lists UnitedHealthcare commercial, Medicare Advantage and Medicaid plans as affected, and says Ascension Living senior communities are not part of the change.
In Oklahoma, the Ascension St. John notice gives the same January 1, 2027 expiration for all of its hospitals, clinics and outpatient sites. The Oklahoma page names UnitedHealthcare commercial and Medicare Advantage coverage and says the termination does not include Medicaid.
In Kansas, Ascension Via Christi says its contract also expires January 1, 2027. The Kansas list is the broadest of the three: UnitedHealthcare commercial, Medicare Advantage, Exchange (marketplace) and Medicaid plans. The Kansas page adds that a separate termination for Ascension Living would take effect March 31, 2027.
The question the Ascension notices leave open: A UnitedHealthcare Medicare Advantage member who sees Ascension doctors in Texas, Oklahoma or Kansas has to decide by December 7 whether to stay put or move to a plan that keeps those doctors, and a provider call script for confirming each doctor’s 2027 network status is part of The 2027 Medicare Open Enrollment Decision Kit.
What out-of-network status would mean for patients
All three Ascension notices draw the same line between emergencies and everything else. Emergency care stays covered regardless of network status. Non-emergency care at an out-of-network Ascension facility may cost more out of pocket or may not be covered at all, depending on the plan.
That difference matters most for planned care: surgeries already on the calendar for early 2027, follow-up visits with a specialist, imaging and ongoing treatments. Ascension suggests patients ask whether an appointment can be moved earlier, before coverage changes, when that is medically reasonable.
Patients in the middle of treatment may have a narrower bridge. The Texas notice says people in active treatment, such as pregnancy or radiation therapy, may qualify for temporary in-network coverage through continuity-of-care rules. The request goes to UnitedHealthcare, not to Ascension, and the insurer decides each case individually.
The December 7 deadline for Medicare Advantage members
Medicare’s annual Open Enrollment Period runs from October 15 to December 7, and changes made in that window take effect January 1, the same day the Ascension contracts expire. During Open Enrollment, Medicare Advantage members can switch plans, drop Medicare Advantage for Original Medicare, or add or drop drug coverage. The new plan must receive the enrollment request by December 7.
The Texas notice goes further than the other two and names Medicare Advantage carriers that it says keep Ascension Texas in-network: Aetna, Blue Cross and Blue Shield of Texas, Humana, Provider Partners Health Plan, Texas Independence Health Plan, Wellpoint in the Austin area only, and Baylor Scott and White in the Waco area only. Those are Ascension’s statements about its own contracts, and network status can differ plan by plan within the same company, so each plan’s 2027 directory is the place to confirm.
A member who switches out of UnitedHealthcare and then sees the two sides settle has not lost anything permanent, but would be in a different plan for 2027 with its own premiums, drug list and copays. A member who stays and sees no deal faces the out-of-network rules above for any non-emergency Ascension care.
A possible second window after the deadline
Medicare has a separate safety valve for network disruptions. Its special enrollment period rules say a person may qualify for a special enrollment period after being notified of a significant change in a plan’s provider network. Medicare evaluates those situations case by case, and a person who qualifies gets two months to join or switch plans or return to Original Medicare.
That window is not automatic, and it depends on how Medicare treats a given network change. People who want certainty about January 1 coverage have the regular December 7 deadline, which requires no approval.
Employer, marketplace and Medicaid members
People with UnitedHealthcare through a job do not have Medicare’s enrollment calendar. Ascension’s Texas notice suggests they talk to their employer’s human resources department about plan options, and the Texas page encourages patients to call the member services number on the back of their insurance card and ask that Ascension stay in network.
In Kansas, Ascension lists marketplace Exchange plans among the affected UnitedHealthcare products, so the January 1 date reaches people who buy their own coverage as well. Medicaid members in Texas and Kansas are in a different position again, because Medicaid plan choices follow state rules rather than Medicare’s calendar. Oklahoma’s notice says Medicaid is not included there.
None of the three notices says how close the two sides are to agreement. Contract disputes of this kind are often settled close to, or even after, the deadline, which is why the dates on the calendar matter more than predictions about the outcome.
Weighing a plan switch around the Ascension deadline
UnitedHealthcare Medicare Advantage members who use Ascension hospitals in Texas, Oklahoma or Kansas are choosing before December 7 without knowing whether the January 1 contract cliff will hold. Keeping the current plan or moving to one that lists Ascension in-network means comparing premiums, prescriptions and each doctor’s 2027 network status side by side.
The 2027 Medicare Open Enrollment Decision Kit pairs a cost calculator spreadsheet that compares plans on cost, drugs and doctors with a provider call script and the Open Enrollment calendar, so each option can be checked against the same list of doctors.
