Three South Jersey hospitals run by Jefferson Health are on track to leave Horizon Blue Cross Blue Shield of New Jersey's network on March 1, 2027, unless the two sides strike a new deal before then. Jefferson's Cherry Hill, Stratford, and Washington Township hospitals are at the center of the standoff, which has already triggered contract termination notices and a public war of words over who is shortchanging whom.
Jefferson Health and Horizon reached an impasse in contract talks, according to the Philadelphia Inquirer. Horizon told the paper that Jefferson terminated its contract effective Sunday, though patients will still be able to get in-network care at the three South Jersey hospitals through Feb. 28 under New Jersey law. Horizon also said cancer and psychiatric patients in New Jersey could keep receiving in-network care from Jefferson for a full year even without a new contract.
The dollar figures at stake are substantial. Horizon said meeting Jefferson's demands would cost its members more than $185 million over the next three years, and argued that New Jersey residents should not have to pay for Jefferson's losses in Pennsylvania, per the same Inquirer report. Jefferson, for its part, says it is being underpaid relative to its peers: the health system told patients that Horizon pays other New Jersey hospitals 146% more on average for inpatient care and up to 89% more for emergency care than it pays Jefferson.
Jefferson Says It Just Wants Parity, Not a Premium
Jefferson said it wants Horizon to narrow that payment gap rather than turn Jefferson into the highest-paid system in the state, the station's report noted. The health system also accused Horizon of abruptly canceling all discussions during active negotiations, warning that the insurer's refusal to keep talking puts patients' well-being at risk. “We stand ready to meet with Horizon any time, any day, any location on behalf of our patients,” Jefferson said, according to the same account.
Horizon is described in the report as New Jersey's largest insurer, giving the dispute outsized stakes for patients across the region who rely on Jefferson, which is identified as the Philadelphia region's largest health system. Neither Jefferson nor Horizon has said how many patients would be affected if the contract lapses.
Jefferson Is Juggling Multiple Insurer Standoffs at Once
The Horizon fight is not Jefferson's only high-stakes negotiation. The health system is also in contract talks with Highmark and Independence Blue Cross, and it issued a notice that it could go out of network with Highmark, identified as Pennsylvania's largest Blue Cross Blue Shield company, on Jan. 1, 2027. In its dispute with Independence, Jefferson's focus is on the insurer's alleged underpayment relative to national averages across the entire market rather than on local competitors, per the Inquirer's reporting.
Jefferson has also clashed with insurers outside the immediate Philadelphia market. Jefferson Lehigh Valley Health Network went out of network with UnitedHealthcare in two phases across 2025 and 2026, the same report noted. Those earlier breaks come against a backdrop of financial strain for the system: Jefferson Health reported a $252.6 million operating loss for the nine months ended March 31, 2026, according to a separate Inquirer report on the system's finances.
A Familiar Pattern Across New Jersey Hospitals
Jefferson and Horizon's standoff fits a broader pattern playing out across New Jersey. A report on a separate hospital-insurer dispute found that it has become increasingly common for hospitals and insurers to publicly threaten to end their contracts entirely, creating anxiety for patients, according to Gothamist. In one earlier case, Hackensack Meridian threatened to end its Aetna contract over a billing dispute after the two sides spent a year negotiating payment rates without an agreement, but they ultimately struck a deal just two weeks before the contract was set to expire, Gothamist reported.
Horizon has also tangled with other New Jersey systems. The insurer said St. Joseph's University Medical Center and St. Joseph's Wayne Medical Center would leave its network on March 1, 2026, amid their own contract dispute, according to NJBIZ. St. Joseph's Health said at the time that Horizon's reimbursement rates had not kept up with inflation and were inadequate to cover the cost of care, and a four-month continuation period allowed the hospital system to keep treating Horizon members under the expired contract's terms while talks continued. Earlier in 2026, Hackensack Meridian Health and Horizon reached a new multiyear contract after their own rate negotiations, NJBIZ reported.
Under New Jersey law cited in the Inquirer's reporting, a carrier must promptly notify each covered person before a provider is terminated or withdrawn from its network, though the available legal text does not spell out additional details on the timing of that notice or the scope of the patient-care continuation periods described by Horizon. With four months still to go before the March 1 deadline, it remains unclear whether Jefferson and Horizon will follow the path of Hackensack Meridian and Aetna toward a last-minute deal, or whether South Jersey patients will actually see their coverage lapse.
