NKC Health, the North Kansas City system that was formerly North Kansas City Hospital and Meritas Health, stopped taking UnitedHealthcare Medicare Advantage plans as an in-network provider on October 1, 2026. The change covers three plan families: UnitedHealthcare Medicare Advantage, AARP/Optum plans and UnitedHealthcare Dual Complete. Members who see NKC Health doctors or use its hospital now face out-of-network rules, and the system has told them to check what their own plan allows. Medicare’s yearly enrollment window opens October 15, which gives affected members a chance to pick a plan that still includes NKC Health before 2027 coverage starts.
What NKC Health announced for UnitedHealthcare members
NKC Health posted a coverage update saying that beginning October 1, 2026, it is out of network with UnitedHealthcare Medicare Advantage plans, AARP/Optum plans and UnitedHealthcare Dual Complete. The notice was last updated in August 2026. A banner on the system’s accepted insurance page, which carries an August 14, 2026 update date, repeats the warning about changes to UnitedHealthcare Medicare Advantage coverage effective that same day in October. That page lists UnitedHealthcare Medicare Advantage as excluded, though it still accepts other UnitedHealthcare products such as Golden Rule and Medica Choice.
The October change is the second Medicare Advantage insurer the system has dropped in two years. The system’s news page says Aetna Medicare Advantage was terminated effective October 1, 2024, and the insurance list still shows Aetna Medicare Advantage as excluded. The same list excludes HealthSpring, the Cigna Medicare Advantage brand, and a Humana plan called Humana Community HMO Medicare Advantage. Standard Humana Medicare Advantage is on the accepted list, and the system names Humana Medicare Advantage, Original Medicare and Medicare Supplement plans as the in-network options.
For a member of one of the three plans, the decision before December 7 is whether to keep the current plan and live with out-of-network rules at NKC Health, or to move to a plan that includes the system. The 2027 Medicare Open Enrollment Decision Kit, a paid guide from RetireShield, includes a provider call script for asking a plan whether NKC Health doctors are in network and a cost calculator spreadsheet that compares plans on cost, drugs and doctors.

NKC Health also made a promise that does not depend on any contract. Its notice says “Emergency care will always be available to you, regardless of our payer contract status.” Medicare’s own guide to Medicare Advantage plans backs up the other side of that promise, saying members are always covered for emergency and urgent care. A member who lands in the NKC Health emergency department after October 1 is therefore a different case from one who books a routine visit or a planned procedure there.
How the plan type changes the bill
The size of the problem depends on the kind of plan a member holds. NKC Health’s notice sorts the UnitedHealthcare plans into groups. Group Medicare Advantage plans, which come through an employer or retiree benefit, may offer open access and out-of-network coverage. PPO plans may include out-of-network benefits, but with higher cost-sharing. HMO-POS plans typically lack out-of-network benefits, and the notice tells those members to consider switching during enrollment.
Medicare’s official guide to Medicare Advantage describes the same split. In an HMO, it says, members generally must use doctors, providers and hospitals in the plan’s network. In a PPO, members can generally go outside the network for covered services but usually pay more. The guide adds that HMO plans typically do not cover non-emergency care outside the network without authorization. A UnitedHealthcare member cannot tell from the plan’s brand name alone which of these rules applies, so the plan’s evidence of coverage and the number on the member ID card decide it.
The notice leaves out dollar amounts, so how much more a PPO member would pay at NKC Health is not stated anywhere in it. That figure sits in each plan’s own benefit documents, along with the out-of-pocket maximum that caps a year of costs. For a member with a standing course of treatment, such as dialysis visits, infusions or follow-up surgery, the difference between a higher copayment and no coverage at all is a question for the plan itself, and the system points members to their insurer for that answer.
The 90-day continuity request
NKC Health says patients with qualifying conditions can ask UnitedHealthcare for a continuity of care exception, abbreviated CoC, that gives 90 days of coverage. The notice is blunt about who decides: approval rests solely with UnitedHealthcare, and the hospital cannot grant it. The notice does not list which conditions qualify, and it does not say how long UnitedHealthcare takes to answer. Patients in the middle of treatment are the ones most likely to need the request, and they would submit it to the insurer rather than to the health system.
A 90-day window has limits that matter in October. A request approved now would run into January, which is when 2027 plan choices begin. That timing makes the continuity request a bridge rather than a fix, buying time for a member who has picked a new plan or who needs the weeks to move a course of care to a network doctor. It does not replace the enrollment decision, because the exception expires after its 90 days while the plan the member holds in January stays in place all year.
Switching plans in the fall is the route NKC Health itself recommends. Its notice lists three in-network directions: Original Medicare, Humana Medicare Advantage and Medicare Supplement plans. A Medicare Supplement policy, also called Medigap, pairs with Original Medicare, and the Medicare guide notes a federal trial right to buy one for people who joined a Medicare Advantage plan for the first time and return to Original Medicare within 12 months. Members who have been in Medicare Advantage longer should ask whether a Medigap insurer will accept them before dropping a plan.
Picking coverage between October 15 and December 7
Medicare says on its enrollment periods page that open enrollment runs October 15 to December 7, and that coverage chosen then starts January 1 of the next year, provided the plan gets the request by December 7. NKC Health’s notice gives the same dates. People already in a Medicare Advantage plan get a second chance from January 1 to March 31, when they can switch plans or return to Original Medicare. That later period starts after the fall decision, so a member who waits keeps the UnitedHealthcare plan, and its out-of-network rules for NKC Health, into the new year.
Before comparing, a member can list each NKC Health doctor, clinic and prescription in use, then ask each candidate plan whether those doctors are in its 2027 network. Medicare’s guide says that if a doctor leaves a plan’s network, the plan must notify the member, who then needs to choose another network doctor. NKC Health takes questions about the change at (816) 691-1340, and Medicare answers plan questions at 1-800-633-4227. Free counseling is available through the State Health Insurance Assistance Program at 877-839-2675, which the program describes as one-on-one help with enrollment and coverage options.
The dates leave a short runway: the contract ended October 1, enrollment opens two weeks later, and it closes December 7. NKC Health has not said how many UnitedHealthcare members use its doctors or whether talks with the insurer continue, and UnitedHealthcare’s side of the dispute is not part of the system’s notice. A member who confirms an in-network plan with a phone call and the plan’s own provider directory before December 7 will know where January care stands.
The 2027 Medicare Open Enrollment Decision Kit adds a prescription-by-plan comparison for the drug side of the choice and an Open Enrollment calendar for tracking the October 15 to December 7 window, as a paid companion to Medicare’s own enrollment tools rather than a way to enroll.
