Vertical integration in healthcare has picked up impressive momentum. In just over a decade, the share of doctors employed by larger health systems has more than doubled, and nearly half of all physicians in the United States are now part of bigger corporate entities. (Between 2012 and 2022, the share of doctors in private practices dropped from 60.1% to 46.7%, while the share employed in hospital-owned or affiliated practices jumped from 29% to 41%.)

Many leaders consider these acquisitions necessary, especially when regulatory pressures, technology costs, and reimbursement challenges weigh on independent practices. However, while hospital-owned clinics can offer centralized resources and bargaining leverage, some recent studies suggest the end result is not always lower costs or improved outcomes for patients. Instead, there’s evidence that this wave of consolidation may, in certain cases, be driving prices up, rerouting patients to pricier facilities and complicating the physician-patient relationship in unanticipated ways.

Let’s walk through why this shift is happening, what benefits it can bring, the challenges emerging along the way, and how healthcare stakeholders can move forward with a thoughtful approach.

What Is Vertical Integration in Healthcare? A Quick Overview

Vertical integration in healthcare basically means hospitals or health systems own the entire chain of care—physician practices, labs, pharmacies, and even specialty clinics. Just think of a hospital acquiring a chain of primary care clinics and specialty offices.

Conceptually, this will be created as a single umbrella organization—one that can handle everything from routine checkups to complicated surgeries. Initially, many industry insiders saw this as an opportunity to streamline care coordination and reduce overhead by combining administrative tasks. With the new payment models, it’s less about how many patients you see and more about how well you care for them.

The policy landscape has also nudged stakeholders in this direction. Federal programs have pressed hospitals and physician groups to consider risk-based contracts and alternative payment models that reward collaboration and outcome. Further, some smaller physician practices have struggled with increasing administrative burdens. Joining forces with a large hospital often seems like the more sustainable path.

As reported in an analysis by the American Medical Association, four in five physicians pointed to the need for better negotiation power with insurers as a key reason for moving under a hospital’s wing. The hope is, together, they might endure financial uncertainty and accelerate improvements in patient experiences.

How Vertical Integration Improves Healthcare Outcomes

One of the most frequently mentioned benefits is the promise of a unified clinical strategy. When doctors and hospitals share the same parent organization, there’s a theoretical advantage in having shared incentives.

No more separate silos squabbling over how to care for patients or split reimbursements. Instead, an integrated system can allocate budgets, personnel, and other resources more fluidly. Specialists can communicate with primary care teams on shared digital health platforms. Patients, in theory, navigate a “one-stop shop” for all medical needs, whether it’s imaging, blood work, or follow-up with a pharmacist.

Hospitals with broad networks can also standardize protocols, theoretically elevating care outcome. For instance, a vertically integrated system may adopt universal guidelines to reduce duplicate tests, prevent medication errors, and unify discharge planning. Some organizations tout that streamlined electronic record systems let them reduce redundant labs and expedite diagnoses. In best-case scenarios, vertical integration in healthcare can spare patients the hassle of re-entering their information or repeating the same procedures at every turn.

Challenges of Vertical Integration in Healthcare

Despite the appealing picture, the data show that integration doesn’t always translate into cost savings. Several analyses of Medicare spending on imaging and lab services, for instance, found that once practices become part of a hospital system, the volume of hospital-based procedures rises noticeably.

(One study observed a monthly increase of 26.3 imaging tests and 44.5 lab tests per 1,000 beneficiaries in hospital settings after integration, along with a corresponding decline in non-hospital tests.) Medicare tends to reimburse hospital-based services at higher rates than the same services performed in an independent office. Consequently, costs go up while the patient’s share of expenses can also increase—an unwelcome surprise for those who thought they were following their doctor’s orders.

(Those higher facility fees translated into per-test reimbursements that rose by about $6.38 for imaging and $0.57 for labs, totaling an extra $40.2 million and $32.9 million in Medicare spending, respectively, over a few years.)

Along with escalating prices, there are studies showing that patient outcomes can stagnate or even worsen when hospital acquisitions disrupt longstanding clinical workflows. For example, some integrated groups might cut back on amenities like dedicated anesthesiology teams for certain procedures. (In one sample of 2.6 million colonoscopies, integrated physicians were found to reduce deep sedation by 3.7 per 100 patients, leading to higher complication rates, including 3.8 more major issues per 1,000.) In other cases, large systems may drive patients toward their own facilities even if those facilities are farther away or less convenient, undermining the patient’s freedom of choice and potentially causing delays. Patients have reported feeling like they’re being funneled into more expensive hospital outpatient departments when independent sites would have been just as good or better.

Meanwhile, physicians sometimes discover that working for a corporate entity narrows their clinical autonomy. Budget constraints can lead to stricter protocols for tests, referrals, or patient length of stay. Some doctors thrive in these settings, relieved to be rid of billing hassles and overhead stress. Others, however, lament the loss of entrepreneurial decision-making, noting that pressure to meet system-wide financial goals can overshadow individualized patient care.

Another difficulty arises when looking at the big picture of market consolidation. Over time, repeated practice acquisitions can reshape entire communities. Fewer independent clinics remain. Competition shrinks. Payors worry that big systems with a local monopoly can demand higher rates with little pushback. Ultimately, that can lead to insurance premium hikes, putting more strain on employers and consumers.

The Future of Vertical Integration in Healthcare

So, how can we strike a better balance?

Many experts suggest recalibrating reimbursement policies so that hospitals do not automatically receive higher fees for routine services that can be delivered elsewhere.
(Medicare, for instance, pays around $917 on average for a colonoscopy performed in a hospital outpatient department versus about $413 in an independent office—a 48% difference.) If payors reduce the site-of-service differential, it may curb the motivation to funnel patients into hospital-owned sites that charge more for the same procedure.

At the same time, integrating organizations can adopt transparent quality measures to keep themselves accountable.

Leaders should also focus on genuine care coordination. Rather than simply acquiring practices, hospitals can emphasize robust clinical integration: shared care pathways, real-time communication between practitioners, and integrated health records. This should be about more than just label changes on the door. True collaboration means investing in systems that detect gaps in care quickly, enabling physicians and nurses across the network to address issues before they become emergencies.

For smaller practices that join large entities, leaders can maintain a measure of independence for frontline clinicians. Some integrated networks experiment with “professional corporations” or partial ownership models where doctors retain a voice in decision-making, ensuring local issues aren’t lost in top-down directives. Clear, open channels for physician leadership can keep morale high and patient care personalized.

Antitrust enforcers and state watchdogs now watch repeated acquisitions more closely, wary that competition might falter. Meanwhile, policymakers work out thresholds that could trigger deeper scrutiny so every deal stays grounded in its real-world context.

(Between 1998 and 2017, nearly 1,600 hospital mergers took place, fueling concern over reduced competition.) Paired with more uniform quality metrics, these efforts help the healthcare sector identify which mergers genuinely improve patient care—and which ones merely inflate costs.)

Summing Up the Impact of Vertical Integration in Healthcare

Vertical integration in healthcare holds promise in theory. It suggests a future where health systems align services, data, and financial arrangements in ways that reduce hassle for patients while boosting operational efficiency and improving patient outcomes.

Unfortunately, real-world results have been mixed. (As one study in Massachusetts showed, vertical relationships alone did not necessarily lower low-value service use or improve outcomes.) We see some gains for large organizations, but we also see concerns about rising prices, questionable referral patterns, and uncertain benefits for patient outcomes.

Ultimately, a system this complex—where payors, regulators, and patient populations have differing priorities—demands fine-tuned oversight. Hospitals, insurers, and policymakers must ensure that the patient’s well-being, not only the bottom line, remains front and center.

As more physicians choose employment within these bigger umbrellas, thoughtful strategies can harness integration’s strengths without being undermined by its pitfalls. By adjusting payment rules, fostering genuine clinical cooperation, and monitoring market power, leaders can still make good on the original idea: delivering accessible, high-quality, and financially sustainable care in every community they serve.

In doing so, the best hopes for vertical integration in healthcare is coordinated care, sensible spending, and a more unified patient journey—might become a reality rather than a mere aspiration.
