Older New Yorkers who count on a UnitedHealthcare Medicare Advantage plan are facing a hard deadline. NewYork-Presbyterian, one of the largest hospital systems in the region, has warned that its hospitals and physician groups will fall out of network for most UnitedHealthcare Medicare Advantage members on September 1 unless the two organizations reach a new contract. Current coverage has been extended only through August 31 while the sides keep negotiating, leaving hundreds of thousands of members waiting to learn whether their hospitals and doctors will still be covered.
The stakes land hardest on people living on fixed incomes. An out-of-network hospital admission can turn a predictable copay into thousands of dollars in charges, and a retiree in the middle of cancer treatment or waiting on a scheduled surgery cannot easily shrug off that uncertainty. The standoff is a reminder that a Medicare Advantage network is only as good as the contracts holding it together.
What happens to the network on September 1
According to the hospital system’s notice to UnitedHealthcare members, if no agreement is reached by August 31, all NewYork-Presbyterian hospitals and the practices that make up the NewYork-Presbyterian Medical Groups will be treated as out-of-network for most UnitedHealthcare Medicare Advantage members starting September 1. For a traditional HMO-style Advantage plan, out-of-network care generally means the plan pays little or nothing outside an emergency, so a routine visit or a planned admission could shift almost entirely onto the patient.
Contract fights like this one have become more common as insurers and hospital systems argue over reimbursement rates. When the two cannot agree, the people caught in the middle are the members who chose an Advantage plan partly because a specific hospital or specialist was listed as in-network.

The exceptions that still keep some coverage
Not every UnitedHealthcare product is affected. The dispute involves Medicare Advantage plans, not AARP-branded Medicare Supplement (Medigap) policies, which continue to work with any provider that accepts Original Medicare. Group Retiree PPO plans are also carved out, and physicians affiliated with ColumbiaDoctors and Weill Cornell Medicine are expected to remain in-network. Members with individual PPO policies or certain group plans may retain some out-of-network benefits, meaning they could still receive partial coverage at NewYork-Presbyterian, though usually at a higher share of the cost.
Those distinctions are worth checking carefully, because two members with the same insurer can end up in very different positions depending on whether they hold an HMO, a PPO, or a supplement plan alongside Original Medicare.
Continuity-of-care protection for active treatment
Members who are in the middle of active treatment are not necessarily cut off on day one. Continuity-of-care rules can allow a patient undergoing an ongoing course of care to keep seeing the same providers at in-network cost-sharing for a transition period, which in this case has been described as running to late November. Medicare requires Advantage plans to manage these transitions, and Medicare’s own guidance on plan coverage underscores that members should confirm how any change affects a treatment already underway. Anyone facing surgery, chemotherapy, dialysis, or a pregnancy-related course of care should ask the plan in writing whether continuity protection applies before September 1.
The dollars at risk for a retiree on a fixed budget
The financial exposure is the reason this dispute belongs in a household budget conversation. In-network hospital care under an Advantage plan is capped by the plan’s out-of-pocket maximum, but out-of-network care can carry a separate, much higher limit or no meaningful limit at all on an HMO. A single inpatient stay that would have cost a manageable copay in-network can balloon into a five-figure bill once a hospital is out of network. For a retiree drawing down savings, that is the difference between a planned expense and a financial emergency.
There is also a fraud-adjacent risk worth flagging. Whenever coverage is in flux, opportunistic callers and mailers target confused seniors with pitches to switch plans, sometimes steering them into products that pay the salesperson well but fit the member poorly. Any unsolicited call claiming a member must act immediately or lose all coverage deserves skepticism, and legitimate plan information can be verified directly with the insurer or with Medicare.
How the timing collides with fall open enrollment
The September 1 deadline arrives just weeks before Medicare’s Annual Enrollment Period, which runs October 15 through December 7 and lets beneficiaries change Advantage or Part D plans for the following year. That overlap gives affected members a real, if narrow, window to react: someone who loses access to a preferred hospital in September can shop for a different Advantage plan, or move to Original Medicare with a supplement, during open enrollment for coverage that begins January 1. Reviewing the plan’s Annual Notice of Change, which insurers must send before the enrollment period, helps members see exactly what is shifting. Details on comparing options are laid out on Medicare’s plan-enrollment pages.
For now, the outcome hinges on whether NewYork-Presbyterian and UnitedHealthcare strike a deal before the extension expires. As regional reporting on the negotiation has noted, last-minute agreements are common in these standoffs, but they are never guaranteed. The prudent move for a member is to confirm current plan type, ask about continuity-of-care protection for any ongoing treatment, and mark the open-enrollment calendar so a September disruption does not become a permanent loss of a trusted hospital.
