Sentara-Anthem Split Could Affect Medicare Choices

Sentara’s move to end its Anthem contracts in Virginia could put nearly 380,000 patients at risk of losing in-network access to the health system if the agreements lapse, according to Healthcare Dive. For people with an Anthem Medicare Advantage plan, the practical issue is whether their preferred Sentara doctors, hospitals, specialists, and facilities would remain covered at in-network rates. The supplied report says the contracts at issue include commercial, Medicare, and Medicaid coverage, but it does not provide a final termination date, replacement agreement, or plan-by-plan member impact.

Sentara is a Virginia-based health system that operates hospitals, physician practices, and other healthcare services. Anthem is a health insurer whose affiliated plans may offer Medicare Advantage coverage in Virginia. Medicare Advantage, also called Medicare Part C, is private-plan coverage that generally uses provider networks and plan-specific rules for routine care.

This is a developing contract matter, not a confirmed loss of coverage for every Anthem member. A notice that contracts may end is different from a completed network change. Still, beneficiaries should treat the news as an early signal to check the status of their own care relationships rather than assume their card will work the same way at every Sentara location.

What the report confirms, and what remains unclear

The verified information supplied with the news item is narrow but important: Sentara is moving to end Anthem contracts in Virginia, and nearly 380,000 patients could be out of network if the commercial, Medicare, and Medicaid agreements lapse. According to Healthcare Dive, nearly 380,000 patients could be affected by a potential out-of-network change involving the health system.

What remains unclear from the supplied material includes which individual Anthem plan products are affected, the specific Sentara facilities and clinicians involved, the proposed effective date, and whether negotiations could produce a new agreement. Those details matter because networks can vary by county, plan type, medical group, hospital campus, and service line. A physician listed as participating today may not remain so if an agreement ends, while emergency care and certain continuity-of-care protections can follow different rules.

Readers should also avoid assuming that a dispute involving commercial coverage applies identically to every Medicare product. The report says Medicare contracts are included, but members need confirmation from their particular plan and provider office. Medicare Supplement insurance works differently from Medicare Advantage: Original Medicare generally allows broad access to Medicare-participating providers, and a Medigap policy helps with Medicare-approved cost-sharing. Part D prescription drug coverage is also primarily about pharmacy and drug formularies, although a health-system network change can still affect the clinicians who prescribe and coordinate medications.

Why provider-network changes matter in Medicare

For Medicare Advantage members, a provider-network change can affect both access and out-of-pocket costs. In-network care usually follows the plan’s regular copayments and coinsurance. If a provider becomes out of network, a member may face higher costs, reduced coverage, referral complications, or the need to select another clinician, depending on whether the plan is an HMO, PPO, or another arrangement.

The highest-impact situations are often ongoing ones: a cancer treatment team, a specialist managing a chronic condition, a planned procedure, rehabilitation, behavioral health care, or a long-standing primary care relationship. Hospital choice can matter too. Even when an individual physician participates in a plan, the hospital, imaging center, surgery center, or other facility used for treatment may have separate network status.

Analysis: the central risk is disruption, not necessarily immediate loss of all care. Contract negotiations can change, and member protections may apply in specific circumstances. However, Medicare beneficiaries have less room for guesswork than people who rarely use medical services. A network shift late in the year may also influence how someone evaluates options during the Annual Enrollment Period, which runs from October 15 through December 7 for coverage beginning the following January.

Members who are already in a course of treatment should ask whether continuity-of-care provisions may be available if a network relationship changes. Eligibility and duration depend on the plan, the care involved, and applicable rules, so this is a question for the insurer and provider, not a benefit to presume.

Practical steps for Anthem members using Sentara

Start by identifying the exact plan name on your insurance card, including whether it is a Medicare Advantage HMO or PPO. Then check the insurer’s current online directory and call member services using the number on the card. Ask whether your specific Sentara physician, hospital, and facility are in network today; whether a contract change has been announced for your plan; and what date, if any, would apply.

Next, contact the clinician’s office. Ask whether the office has received guidance about your plan and whether there are alternatives for upcoming appointments, referrals, labs, imaging, or procedures. Keep notes with the date, representative name, and confirmation number. This documentation can be useful if later information conflicts or a claim needs review.

If you take specialty medications or have scheduled care, ask focused questions: Will the prescribing specialist remain available? Is prior authorization affected? Is there another in-network facility that can provide the same service? What would my estimated member cost be if my current provider is out of network? A plan can answer general network questions, but it may not be able to quote a final cost until the service, coding, and authorization details are known.

What this means for plan selection

This report is a reminder that provider access deserves as much attention as premiums and extra benefits when comparing Medicare Advantage plans. A low monthly premium can be appealing, but a plan’s value depends heavily on whether it includes the doctors, hospitals, pharmacies, and medications a person expects to use.

For Virginians considering a Medicare plan in 2026, compare each option using a short checklist: confirm your primary care clinician and key specialists, check preferred hospitals and facilities, review the drug formulary and pharmacy network, compare maximum out-of-pocket limits, and understand referral and out-of-network rules. PPO plans may offer some out-of-network coverage, but that does not mean all services will be covered in the same way or at the same cost as in-network care.

People turning 65 should not choose coverage based solely on a current provider directory, because networks can change. Instead, use today’s directory as one decision input, review plan materials carefully, and revisit care priorities during enrollment windows. Existing beneficiaries should generally wait for official plan communications and compare their Annual Notice of Change when it arrives before making enrollment decisions.

Medicare Plan Path’s perspective is straightforward: Sentara and Anthem members do not need to assume the worst, but they should verify the facts early and make a care plan if the contracts lapse. If a change would affect an important doctor or hospital, compare available Medicare options and consider speaking with a licensed agent who can explain network and cost differences without providing individualized medical advice.
