Horizon Blue Cross Blue Shield of New Jersey has agreed to acquire Summit Health's New Jersey operations, including the state's CityMD urgent care locations, in a deal that would hand the state's largest and oldest health insurer direct control over a sizable chunk of physician practices and walk-in clinics. The transaction still needs to clear regulatory review, and the financial terms have not been disclosed.
According to beckerspayer.com, Horizon has agreed to acquire multispecialty physician group Summit Health's New Jersey operations, including the CityMD urgent care sites in the state. Summit operates more than 120 locations across New Jersey, New York and Connecticut, while CityMD runs more than 180 urgent care centers across those same three states. Horizon framed the move as an effort to preserve access to high-quality care for Summit Health's patients, according to a spokesperson cited by the outlet.
ROI-NJ's report notes that the purchase price remains undisclosed, though some media outlets have reported a figure of $1 billion — a number that has not been independently confirmed. The ROI-NJ report also describes the deal as Horizon's biggest since a 2020 state law first enabled the insurer to convert into a nonprofit mutual holding company.
A Spokesperson's Pitch on Access and Independence
Beyond preserving access, Horizon says it intends to improve healthcare quality and affordability for its members and to support the continued independence of Summit Health's physicians and clinicians, per the spokesperson's comments relayed in the ROI-NJ report. Those commitments, as described, apply to how Horizon characterizes its own intentions rather than any outside verification of the deal's specific terms.
The acquisition would mark a significant escalation of a strategy Horizon has been building since its corporate structure changed. New Jersey approved Horizon's conversion from a nonprofit health service corporation into a nonprofit mutual holding company — Horizon Mutual Holdings — in 2022, a restructuring that the same beckerspayer.com report says allowed the insurer to create for-profit subsidiaries and pursue acquisitions of providers and pharmacy benefit managers for the first time. Separately, New Jersey's Department of Banking and Insurance approved Horizon's application for that reorganization under a 2020 state law, according to the New Jersey Department of Banking and Insurance.
Horizon's First Taste of Dealmaking
Horizon's push into provider acquisitions didn't start with Summit Health. The insurer acquired Minnesota-based HealthEZ in 2025, a move the report notes was intended to help launch a third-party administrator business in its home market in 2027. That transaction gave Horizon its first real experience operating outside the traditional insurance-carrier lane before this latest, much larger target came into view.
Summit Health itself has already changed hands more than once. The company was formed through the 2019 merger of Summit Medical Group and CityMD, the report notes, and in 2025 private equity firm Sycamore Partners took Walgreens private in a deal that separated VillageMD, Summit Health and CityMD into a standalone company. That separation set the stage for Horizon's New Jersey-focused bid, even as Summit's footprint in New York and Connecticut remains outside the scope of this particular agreement.
Part of a Bigger Pattern in Healthcare
Horizon's interest in owning physician practices and urgent care sites fits a broader trend among Blue Cross Blue Shield plans, which beckerspayer.com describes as a growing number moving directly into care delivery rather than simply paying for it. The pressures pushing doctors toward consolidation are well documented elsewhere: the American Hospital Association reports that 94% of physicians say running a solo practice has become more financially and administratively difficult, while just 42% of physicians remain in private practice at all, compared with 10% of all U.S. workers who are self-employed. The AHA also notes that, after adjusting for inflation, Medicare physician payment effectively fell 29% between 2001 and 2024 — a squeeze that has made many independent practices more open to being bought out.
Insurers specifically have been aggressive buyers in this environment. The AHA's analysis found that commercial health insurers acquired roughly 40% more physicians than hospitals did over the preceding five years, a dynamic that stands in contrast to hospitals, which the AHA says are more likely to acquire less profitable specialties such as family medicine, pediatric medicine and primary care. A Health Affairs study of Optum's practice acquisitions between 2013 and 2021 adds another data point to the broader consolidation story: the research found no significant shift in referrals from hospital outpatient departments to ambulatory surgery centers, though it also found that Optum preferentially acquired practices that already had high rates of ambulatory surgery center use, according to Health Affairs.
For context on just how large these physician-group transactions can get, Summit Health and CityMD's prior ownership change was a multibillion-dollar affair. VillageMD agreed to acquire Summit Health-CityMD from Warburg Pincus for approximately $8.9 billion in cash and equity in a deal signed on November 7, 2022, according to Cleary Gottlieb. At the time, Summit Health and CityMD together had more than 2,800 providers across more than 370 locations spanning five states, and Walgreens Boots Alliance along with Evernorth, a Cigna subsidiary, planned to invest in VillageMD as part of that transaction.
For now, Horizon's agreement with Summit Health covers only the New Jersey operations, and the path forward depends on how regulators respond to a deal that would deepen the insurer's footprint in direct patient care across the state it has long dominated as a payer.
