A contract fight between one of Virginia’s largest hospital systems and one of its biggest insurers has quietly put hundreds of thousands of patients on notice. Sentara Health has signaled it will end its network agreement with Anthem, and if no new deal is struck, as many as 380,000 Virginians could find their hospitals and doctors treated as out of network starting January 1. For older residents on fixed incomes, the stakes are less about headlines than about whether a familiar cardiologist or hospital still counts as covered next year.
Why a contract dispute, not a plan exit, is driving this
The situation differs in an important way from the wave of insurers dropping Medicare Advantage plans for 2027. Nobody’s plan is being cancelled here. Instead, a provider system and an insurer cannot agree on payment terms, and the provider is threatening to walk away from the insurer’s network. When that happens, the insurance card stays valid, but the hospitals and physicians inside the departing system may no longer be considered in network.
That distinction matters because the remedies are different. A cancelled plan triggers automatic notices and special enrollment protections. A provider going out of network usually does not cancel anyone’s coverage; it simply changes what that coverage pays for at those specific facilities. The insurer remains, the plan remains, and the burden shifts to the member to confirm which doctors and hospitals are still in network.
What “out of network” actually costs
Out-of-network care is where the financial damage lands. On a commercial or Medicare Advantage plan, in-network providers are the ones the insurer has negotiated discounted rates with. Step outside that network and the plan may pay a smaller share, apply a separate and higher deductible, or in some designs decline to pay routine care at all. The patient covers the gap.
For someone managing a chronic condition, that gap is not theoretical. A standing relationship with an oncologist, a scheduled surgery, or ongoing specialty care at a Sentara facility could suddenly carry a far larger price tag if the contract lapses. Emergency care is generally protected regardless of network status, but planned and routine visits are exactly the kind of care most retirees rely on month to month.

The January 1 deadline may still move
Contract standoffs like this one frequently resolve at the last minute. Public termination notices are often a negotiating lever, and it is common for a payer and a provider to announce a split, exchange sharp statements, and then sign a fresh multi-year deal days before coverage would actually change. The January 1 date is real, but it is a pressure point, not a certainty.
Because the outcome is genuinely unsettled, the practical response is to watch the mailbox and the two organizations’ member notices rather than react to early headlines. If a deal is reached, network access continues without interruption. If it is not, affected members will need a plan for where to get care after the new year.
The options if the split becomes final
Should the contract actually end, affected residents generally have a few paths. Members can stay with their current insurer and switch to in-network hospitals and physicians, or they can look at whether a different plan keeps their preferred Sentara providers in network. Those on Medicare Advantage have a built-in chance to change plans during the Medicare fall Annual Enrollment Period, which runs October 15 through December 7 and lets enrollees compare plans and switch coverage for the coming year.
Anyone in the middle of a treatment course has an additional protection worth asking about: continuity-of-care provisions. Many plans are required to let patients finish an active course of treatment with an out-of-network provider at in-network rates for a transition period, particularly for pregnancy, cancer treatment, or a scheduled surgery. That is a request the member has to make; it is not automatic.
Notice rules and a possible special enrollment period
Members are not meant to be blindsided. Insurers and provider systems generally must give affected patients advance written notice when a major contract is ending, which is why watching for those letters matters as much as tracking the headlines. For Medicare Advantage enrollees there is an additional, less-known avenue: when a plan undergoes a significant mid-year change to its provider network, the Centers for Medicare and Medicaid Services can authorize a special enrollment period that lets affected members switch plans outside the normal fall window. That relief is not automatic and is granted case by case, so it cannot be assumed. Confirming directly with the plan whether any special enrollment right applies, rather than waiting for it to appear, is the way to learn whether an early exit is even on the table.
What to confirm before year-end
The concrete steps are unglamorous but decisive. Confirming in writing whether a specific hospital and each treating physician will be in network in 2027 is more reliable than assuming, because network status can vary provider by provider even within one system. Checking the plan’s out-of-network cost-sharing shows what an unresolved split would actually cost. And for Medicare Advantage members, comparing plans during Annual Enrollment is the cleanest way to lock in coverage that keeps the right doctors in network.
The broader lesson from disputes like the Sentara-Anthem standoff, tracked closely in payer-industry reporting, is that a valid insurance card no longer guarantees a valid relationship with a given hospital. Networks are renegotiated every year, and the terms can shift under patients who never changed a thing about their own coverage. Verifying the network before the calendar turns is the one move entirely within a member’s control.
