Three health systems, three different endings. Fairview in Minnesota has decided it will stop scheduling UnitedHealthcare Medicare Advantage patients on January 1. OHSU in Oregon will leave Regence’s Medicare Advantage plans the same day. AdventHealth in Florida sees its UnitedHealthcare contract end December 31, with no new deal listed on its own page.
All three dates land after the December 7 close of Medicare’s open enrollment, and new coverage starts January 1. For members of those plans, the choice to stay or switch has to be made while the hospital is still in the plan.
Fairview: a firm stop on January 1
Fairview’s UnitedHealthcare update page says it will no longer schedule patients with UnitedHealthcare Medicare Advantage plans beginning January 1, 2027. It cites frequent coverage changes, denials and payment issues. The page also says UnitedHealthcare information stating Fairview stays in network after that date “is incorrect.”
Emergency care stays available at all times, and UnitedHealthcare commercial members remain in network. Fairview lists Blue Cross Blue Shield of Minnesota, HealthPartners and Medica as in-network Medicare Advantage options, and says many Original Medicare plans are accepted. Becker’s Hospital Review’s running list of systems carries the same January 1 date.
Anyone in a UnitedHealthcare Medicare Advantage plan who gets care at Fairview has a clear job: pick a plan that keeps Fairview in network, or accept paying elsewhere. Fairview tells patients in active care to ask their care team about continuation of coverage. Members should also ask their insurer for the Annual Notice of Change.

Fairview points members to free one-on-one help from Chapter, a team of licensed independent Medicare advisors, at (855) 797-3811. It also lists Minnesota Aging Pathways, formerly the Senior LinkAge Line, at 1-800-333-2433. Fairview runs its own 24/7 line at 1-855-324-7843 and a language assistance line at 612-273-3780. The page names Medicare’s Plan Finder as a tool for comparing what each plan covers.
OHSU: the deal that stopped short of Medicare Advantage
OHSU’s story is a half resolution. On its patient page, the hospital says it reached agreement with Regence on new multi-year contracts on August 27, 2026. Employer-sponsored and other commercial members stay in network at OHSU, its hospital, Doernbecher Children’s Hospital and its clinics.
Medicare Advantage and individual-plan members are not covered by that deal. On January 1, 2027, OHSU and Hillsboro Medical Center will no longer be participating providers in Regence Medicare Advantage HMO and PPO plans or Regence individual plans. A transition period lets Regence members keep in-network care through December 31, 2026.
OHSU said in a statement: “We are pleased to have reached an agreement, so patients can continue getting the care they need at OHSU.” The page tells Medicare Advantage and individual members to contact Regence about out-of-network benefits and to review plan options in the fall enrollment periods. Hillsboro reached a separate agreement for commercial members. The page does not name replacement Medicare Advantage plans, so members who want to keep OHSU have to find one that includes it.
AdventHealth: a contract that may not be replaced
AdventHealth’s UnitedHealthcare page says its current agreement with United ends December 31, 2026. It says United has terminated the contract, and that without a new deal AdventHealth is out of network on January 1, 2027. The page says all clinicians and services at its Florida locations are affected.
The dispute reaches beyond Medicare. The page says it affects United members with Medicare Advantage, Individual and Family exchange, commercial and Medicaid plans. AdventHealth says it is “not seeking rate increases above inflation” and warns that without a deal members “may have to pay more” to see its clinicians.
For now, AdventHealth says nothing has changed and members should keep using its care as usual. Some may keep seeing their current clinicians at in-network rates for a set period, though United reviews each request and decides. The page advises members who are pregnant or in complex treatment to ask United about continuity of care. Emergency care is available regardless of network status.
What December 7 does and does not fix
Medicare’s joining a plan page says that from October 15 to December 7, people can switch Medicare Advantage plans or return to Original Medicare, and coverage starts January 1. Medicare’s Plan Finder is the official place to compare plans.
The three are not alone. Becker’s list, headlined “34 health systems dropping Medicare Advantage plans,” also names Lee Health in Fort Myers (UnitedHealthcare, end of 2026), Sentara Health in Norfolk (Anthem, end of 2026) and Endeavor Health in Evanston (Aetna, past 2026). Becker’s says the list is not exhaustive.
Fairview and OHSU have set their dates. AdventHealth’s turns on a negotiation. A member in Florida would be choosing a plan without knowing whether a deal will land before the new year, so the question is the same for all three states: if my hospital leaves my plan in 2027, which plan keeps my doctors before December 7?
Will your hospital still be in your plan on January 1?
A hospital that leaves a plan can leave a member paying out-of-network prices for the same surgeon on January 1, and open enrollment ends December 7. Fairview, OHSU and AdventHealth each have a different date and a different plan affected.
