The Four Core Beliefs of Hospital-Employed Physicians

In my report June 10, I wrote: “The major sources of physician discontent are administrative hassles and unwelcome clinical oversight that create dissonance. They conflict with a false sense of autonomy that the majority of physicians imagined when choosing medicine. Cuts to reimbursement, participation in alternative payment models and medical inflation are manifestations of a system in which ‘suits’ are intruders who make rules, exact handsome salaries, generate corporate profits and distance physicians from patient care purposely… “

This assessment remains true today. Discontent among physicians is palpable and it’s magnified by a growing sense of financial despair among many clinicians. And it poses a unique challenge to hospitals that now employ more than half of America’s physician workforce.

In the “good ole days”, hospitals provided a place for physicians to ply their trade. They were credentialled to practice their chosen specialty, granted special parking, food and amenities and treated as the hospital’s most welcome customer. Made sense: physicians controlled most patient decisions about the hospital services they use. Physicians controlled the hospital’s revenue, sustainability and bonuses earned by administrators. Insurers brought privately-insured patients to doctors who charged them 1.6-2.5 times what Medicare paid and physician income was not threatened. That was then. This is now.

Today, insurers play a larger role. Consumer expectations have changed. Policymakers are paying more attention. And demand has shifted from inpatient services to outpatient, home and office settings for health and wellbeing services in addition to acute care. And the current forecast by CMS through 2032 predicts spending for hospitals will increase at a compound rate of 5.7% vs. 5.6% for physicians adding more hospital-physician financial tension to the system. Both well-above inflation and CDP growth prompting heightened pressure to spend less.

In anticipation, consolidation of hospitals into multi-hospital systems has been a staple in recent years: only 1 in 5 hospitals is independent these days, and most of these are small, rural or otherwise destined to independence for their uncertain future. Whether public, investor-owned or not-for-profit (or tax exempt as some prefer), the economic realities of running hospitals coupled with the regulatory constraints imposed by state and federal law forced all to re-think their future. And, for most, employing physicians directly was a means to an end of staying alive while the dust settles.

But the unintended consequence of physician employment is soured relationships between the employed physicians and their hospital:

their financial and emotional security has become tangled up by interactions with hospital leaders and former peers appointed to oversee their work.

And their views about their hospital have morphed to negativity based on four underlying beliefs:

  • Hospitals spend too much on overhead and executive salaries and not enough on direct patient care.
  • Hospitals are run poorly: we could run them better but they don’t listen to us.
  • Hospitals get rate increases from Medicare and physicians get screwed.
  • Hospitals need us more than we need them. But they don’t understand that.

On March 9, 2024, President Biden signed the Consolidated Appropriations Act, 2024, which included a 2.93% update to the CY 2024 Physician Fee Schedule (PFS) Conversion Factor (CF) for dates of service March 9 through December 31, 2024. But physicians saw that as not enough since their overhead increased even more. And for 2025, CMS is proposing to reduce average payment rates under the MPFS by 2.93% compared to the average amount reimbursed for these services in CY 2024 based on CY 2025 MPFS conversion factor decrease of $0.93 (or 2.8%) from the current CY 2024 conversion factor.

Understandably, physicians are upset. They’re not delusional that private insurers will make up the difference nor imagining hospitals will divert funds their way from brick, stick and tech priorities. But they’re speaking out expressing their views to anyone who’ll listen.

For hospitals that employ physicians, the issue of their financial anxiety requires urgent attention–not as one of many alongside 340B, site neutral payments and others but as the one at the top of the list. The issue is not whether physician income relative to other professions and average households is high. The issue is about managing physician expectations about their livelihood realistically and practically while improving their clinical acumen as professionals.

The core beliefs held by employed physicians about their hospitals may not be fair, objective or accurate, but they’re no less deeply felt and impactful. Hospital boards and C suite leaders would be well-served to refresh plans accordingly.

8 Reasons Hospitals must Re-think their Future

Today is the federal income Tax Day. In 43 states, it’s in addition to their own income tax requirements. Last year, the federal government took in $4.6 trillion and spent $6.2 trillion including $1.9 trillion for its health programs. Overall, 2023 federal revenue decreased 15.5% and spending was down 8.4% from 2022 and the deficit increased to $33.2 trillion. Healthcare spending exceeded social security ($1.351 trillion) and defense spending ($828 billion) and is the federal economy’s biggest expense.

Along with the fragile geopolitical landscape involving relationships with China, Russia and Middle East, federal spending and the economy frame the context for U.S. domestic policies which include its health system. That’s the big picture.

Today also marks the second day of the American Hospital Association annual meeting in DC. The backdrop for this year’s meeting is unusually harsh for its members:

Increased government oversight:

Five committees of Congress and three federal agencies (FTC, DOJ, HHS) are investigating competition and business practices in hospitals, with special attention to the roles of private equity ownership, debt collection policies, price transparency compliance, tax exemptions, workforce diversity, consumer prices and more.

Medicare payment shortfall: 

CMS just issued (last week) its IPPS rate adjustment for 2025: a 2.6% bump that falls short of medical inflation and is certain to exacerbate wage pressures in the hospital workforce. Per a Bank of American analysis last week, “it appears healthcare payrolls remain below pre-pandemic trend” with hospitals and nursing homes lagging ambulatory sectors in recovering.”

Persistent negative media coverage:

The financial challenges for Mission (Asheville), Steward (Massachusetts) and others have been attributed to mismanagement and greed by their corporate owners and reports from independent watchdogs (Lown, West Health, Arnold Ventures, Patient Rights Advocate) about hospital tax exemptions, patient safety, community benefits, executive compensation and charity care have amplified unflattering media attention to hospitals.

Physicians discontent: 

59% of physicians in the U.S. are employed by hospitals; 18% by private equity-backed investors and the rest are “independent”. All are worried about their income. All think hospitals are wasteful and inefficient. Most think hospital employment is the lesser of evils threatening the future of their profession. And those in private equity-backed settings hope regulators leave them alone so they can survive. As America’s Physician Group CEO Susan Dentzer observed: “we knew we’re always going to need hospitals; but they don’t have to look or operate the way they do now. And they don’t have to be predicated on a revenue model based on people getting more elective surgeries than they actually need. We don’t have to run the system that way; we do run the healthcare system that way currently.”

The Value Agenda in limbo:

Since the Affordable Care Act (2010), the CMS Center for Innovation has sponsored and ultimately disabled all but 6 of its 54+ alternative payment programs. As it turns out, those that have performed best were driven by physician organizations sans hospital control. Last week’s release of “Creating a Sustainable Future for Value-Based Care: A Playbook of Voluntary Best Practices for VBC Payment Arrangements.” By the American Medical Association, the National Association of ACOs (NAACOs) and AHIP, the trade group representing America’s health insurance payers is illustrative. Noticeably not included: the American Hospital Association because value-pursuers think for hospitals it’s all talk.

National insurers hostility:  

Large, corporate insurers have intensified reimbursement pressure on hospitals while successfully strengthening their collective grip on the U.S. health insurance sector. 5 insurers control 50% of the U.S. health insurance market: 4 are investor owned. By contrast, the 5 largest hospital systems control 17% of the hospital market: 1 is investor-owned. And bumpy insurer earnings post-pandemic has prompted robust price increases: in 2022 (the last year for complete data and first year post pandemic), medical inflation was 4.0%, hospital prices went up 2.2% but insurer prices increased 5.9%.

Costly capital: 

The U.S. economy is in a tricky place: inflation is stuck above 3%, consumer prices are stable and employment is strong. Thus, the Fed is not likely to drop interest rates making hospital debt more costly for hospitals—especially problematic for public, safety net and rural hospitals. The hospital business is capital intense: it needs $$ for technologies, facilities and clinical innovations that treat medical demand. For those dependent on federal funding (i.e. Medicare), it’s unrealistic to think its funding from taxpayers will be adequate.  Ditto state and local governments. For those that are credit worthy, capital is accessible from private investors and lenders. For at least half, it’s problematic and for all it’s certain to be more expensive.

Campaign 2024 spotlight:

In Campaign 2024, healthcare affordability is an issue to likely voters. It is noticeably missing among the priorities in the hospital-backed Coalition to Strengthen America’s Healthcare advocacy platform though 8 states have already created “affordability” boards to enact policies to protect consumers from medical debts, surprise hospital bills and more.

Understandably, hospitals argue they’re victims. They depend on AHA, its state associations, and its alliances with FAH, CHA, AEH and other like-minded collaborators to fight against policies that erode their finances i.e. 340B program participation, site-neutral payments and others. They rightfully assert that their 7/24/365 availability is uniquely qualifying for the greater good, but it’s not enough. These battles are fought with energy and resolve, but they do not win the war facing hospitals.

AHA spent more than $30 million last year to influence federal legislation but it’s an uphill battle. 70% of the U.S. population think the health system is flawed and in need of transformative change. Hospitals are its biggest player (30% of total spending), among its most visible and vulnerable to market change.

Some think hospitals can hunker down and weather the storm of these 8 challenges; others think transformative change is needed and many aren’t sure. And all recognize that the future is not a repeat of the past.

For hospitals, including those in DC this week, playing victim is not a strategy. A vision about the future of the health system that’s accessible, affordable and effective and a comprehensive plan inclusive of structural changes and funding is needed. Hospitals should play a leading, but not exclusive, role in this urgently needed effort.

Lacking this, hospitals will be public utilities in a system of health designed and implemented by others.

America’s newest doctors fuel efforts to unionize

https://www.axios.com/2024/04/15/doctors-union-gen-z-millennial

A new generation of doctors struggling with ever-increasing workloads and crushing student debt is helping drive unionization efforts in a profession that historically hasn’t organized.

Why it matters: 

Physicians in training, like their peers in other industries, increasingly see unions as a way to boost their pay and protect themselves against grueling working conditions as they launch their careers.

What they’re saying: 

“We deserve an increased salary to be able to afford to live in one of the most expensive areas in the United States,” said Ali Duffens, a third-year internal medicine resident at Kaiser Permanente’s San Francisco Medical Center.

  • She’s among the 400 residents at Kaiser’s Northern California system filing to unionize earlier this month.
  • Duffens earns about $82,000 per year, while paying $3,000 a month for rent and facing $350,000 in medical school loans.

The big picture: 

The Kaiser residents are part of a growing number of younger peers in medicine who have been unionizing in recent years.

  • The number of medical residents in unions has about doubled to more than 32,000 in three years, per CalMatters.
  • In the last year, residents at Montefiore Medical Center, Stanford Health Care, George Washington University and the University of Pennsylvania voted to unionize, per WBUR.
  • “The cost of day care … in a month is about half of my salary in total, and the cost of a nanny is essentially the entirety of my salary,” Leah Rethy, an internal medicine resident with Penn Medicine, told NPR last year.
  • Residents can work as much as 80 hours per week while earning far less than their older colleagues.

Yes, but: Just about 6%-7% of physicians are estimated to be in unions.

  • Historically, doctors have thought they could just suck up the long hours and relatively low pay in training as part of the tradition of medicine, said Robert Wachter, chair of the department of medicine at the University of California, San Francisco.
  • “For a new generation, they look at it and say, ‘That’s crazy. I can’t believe you did that. I want to work hard, but I also want a life and I want a family, and I want a reasonable income,'” he said.

And it’s not just younger doctors. 

Those more established in their careers are also unionizing as they see the industry changing in ways that they think undermine their profession.

  • In recent months, attending physicians at Salem Hospital, owned by Mass General Brigham, and a Cedars Sinai-owned anesthesiology practice filed to unionize.
  • About 600 doctors at Allina Health in Minnesota and Wisconsin last fall agreed to form what appears to be the largest union of private sector physicians.

Zoom in: 

The corporatization of American medicine is seen as a key driver. More than half of all U.S. doctors now work for a health system or large medical group rather than running an independent practice.

  • This shift has brought heavier workloads and less control over how they care for patients, said John August, director of health care labor relations in the Scheinman Institute on Conflict Resolution at the ILR School at Cornell.
  • That could mean demands to see more patients, limiting the time that doctors can spend with them.
  • “What you will hear from them 100% of the time in every conversation they have is they feel that they have lost control over the patient-physician relationship. I mean, every single physician says that now,” August said.

The other side: 

Health systems and large practices generally say they value their doctors and the relationships they hold with patients.

  • Hospitals have also struggled with pandemic-era financial shortfalls, including increasing labor costs.

The bottom line: 

While this is a labor issue, it ultimately trickles down to quality and safety for patients, said Rachel Flores, organizing director of the Union of American Physicians and Dentists.

  • Patients should care because that’s less time to address their issues,” she said. “Patients should care because there’s not enough staff to support the physician.”

No appointments available: America’s escalating primary care shortage

Chronic disinvestment and inadequate training have created a shortage of primary care workers.

As the presidential election nears, issues from the economy to climate change are vying for airtime, yet markedly absent from the headlines is a deepening crisis that threatens the future health and wellbeing of communities nationwide: a primary care sector on the brink of collapse.  

Primary care is the cornerstone of community health. It helps us live longer lives, prevents disease and reduces health disparities. It is indispensable to strengthening our nation’s ability to withstand another deadly pandemic or climate disaster. And yet, over 100 million Americans report they lack access to a regular doctor or source of care.

Physicians and patients acutely feel the primary care workforce shortage. In recent interviews we heard an alarming refrain from clinicians and health executives: “I could spend all my time helping friends find doctors accepting new patients.” Another said, “I have 100 open staff positions and am in a bidding war for primary care physicians.”

Just in the past decade, there has been a 36% jump in the share of U.S. children without a usual source of care. Among adults it’s a 21% increase, according to a Milbank report. And with America’s rapidly aging population, access to critical primary care services is only expected to get worse. 

Understanding what’s driving America’s primary care workforce shortage is key to finding effective, long-term solutions. 

A workforce exodus amid chronic disinvestment

America is not producing enough primary care physicians to meet growing population needs. New primary care physicians are leaving for other fields at alarming rates. In 2021, only 15% of all physicians were practicing outpatient primary care three to five years after residency, according to a Milbank report. 

When we look at the disparities in compensation rates and the nation’s chronic disinvestment in primary care, this workforce exodus shouldn’t come as a surprise. Specialists in the U.S. now routinely make two to three times what their primary care colleagues do, creating powerful incentives for physicians in training to “go for the gold.” 

Primary care accounts for 35% of healthcare visits but receives only about 5% to 7% of total healthcare expenditures. For context, hospitals account for 30% of healthcare expenditures. Additionally, since 2019, the share of total spending by Medicare, Medicaid and commercial insurers in primary care has steadily declined; Medicare’s share has dropped by 15%, according to Milbank.

Inadequate training, disparities in access

Today, the vast majority of primary care residents train within hospitals and academic health centers, which do not expose them to the needs of underserved communities, nor provide them with the skills needed to successfully practice in challenging, real-world clinical environments. In 2021, only 15% of primary care residents spent a majority of their time training in community settings, outside of hospitals. 

Moving forward, the solutions are clear. Congress and both the public and private sectors must work together to enact stronger federal and state policies in three critical primary care areas. First, Medicare and Medicaid physician reimbursement — which has led to our specialty-dominated healthcare system — must become more effective and efficient. We know that inadequate compensation is one reason why many medical students choose not to go into primary care.  

Second, the billions in public dollars going to clinician training must be focused on creating a highly skilled primary care workforce with practical experience in community settings. This is essential to meet the complex health needs of our nation’s ever-changing and growing population. 

And finally, we need to expand the footprint of community health centers, the linchpin to improving health outcomes in underserved communities. Currently, these centers provide care to 1 in 11 patients around the country, but that number needs to be vastly expanded.

It’s time to strengthen our fragile primary care system to ensure it delivers the comprehensive, affordable care Americans so desperately need. Access to high-quality primary care for everyone should not be an aspiration, but an expectation that we – as a nation – have an urgent duty to fulfill.

Employed physians at Allina Health vote to unionize

https://mailchi.mp/59f0ab20e40d/the-weekly-gist-october-27-2023?e=d1e747d2d8

Around 400 primary and urgent care physicians, along with 150 nurse practitioners and physician assistants, employed by Minneapolis, MN-based Allina Health System have voted to unionize with the Service Employees International Union, forming the largest private-sector union of physicians in the country. 

Allina, which operates 12 hospitals across Minnesota and Wisconsin, already saw over 100 inpatient physicians at its Mercy Hospital vote to unionize earlier this year. While Mercy’s physicians organized against pressure to adhere to the hospital’s new length-of-stay guidelines, this larger group of clinic-based providers say they are motivated by chronic understaffing that they claim has caused burnout and threatened patient safety. Allina Health laid off 350 workers this summer after posting a nearly $200M operating loss in 2022.

The Gist: When health systems originally recruited physicians into their newly developed employed medical groupsmany pitched the arrangement as more of a partnership than traditional employment.

However, now that a majority of the nation’s physicians are employed by hospitals, some physicians are rethinking their relationships with their employers. 

Only six percent of doctors were unionized in 2021, but a recent spate of unionization efforts by residents and physicians suggest that number is on the rise.

Health systems hoping to address physicians’ concerns and unionization activity should note that the motivating factors cited by organizing physicians surround working conditions, including a lack of support staff and professional autonomy, rather than personal wage demands.

Which physician specialties are most targeted for corporate roll-ups?  

https://mailchi.mp/6f4bb5a2183a/the-weekly-gist-march-24-2023?e=d1e747d2d8

In the last edition of the Weekly Gist, we illustrated how non-hospital physician employment spiked during the pandemic. Diving deeper into the same report from consulting firm Avalere Health and the nonprofit Physicians Advocacy Institute, the graphic above looks at the specialties that currently have the greatest number of physicians employed by hospitals and corporate entities (which include insurers, private equity, and non-provider umbrella organizations), and those that remain the most independent.


To date, there has been little overlap in the fields most heavily targeted for employment by hospitals and corporate entitiesHospitals have largely employed doctors critical for key service lines, like cancer and cardiology, as well as hospitalists and other doctors central to day-to-day hospital operations.

In contrast, corporate entities have made the greatest strides in specialties with lucrative outpatient procedural business, like nephrology (dialysis) and orthopedics (ambulatory surgery), as well as specialties like allergy-immunology, that can bring profitable pharmaceutical revenue.

Meanwhile, only a few specialties remain majority independent. Historically independent fields like psychiatry and oral surgery saw the number of independent practitioners fall over 25 percent during the pandemic.

While hospitals will remain the dominant physician employer in the near term, corporate employment is growing unabated, as payers and investors, unrestrained by fair market value requirements, can offer top dollar prices to practices

Lawmakers stress urgency of healthcare worker shortage

https://www.healthcaredive.com/news/lawmakers-fixes-healthcare-workforce-shortages/642994/

Addressing the education pipeline is one thing that legislators could focus on to improve nurse and physician shortages, medical school and health system leaders said.

As the healthcare industry continues to face pandemic-driven workforce challenges, lawmakers are exploring ways to boost the number of clinicians practicing in the U.S.

“A shortage of healthcare personnel was a problem before the pandemic and now it has gotten worse,” Chairman Sen. Bernie Sanders I-Vt., said during a Thursday Senate HELP committee hearing. “Health care jobs have gotten more challenging and, in some cases, more dangerous,” he said.

The country faces a shortage of up to 124,000 physicians by 2034, including 48,000 primary care physicians, according to the Association of American Medical Colleges.

Hospitals are currently facing shortages of registered nurses as burnout and other factors drive them to other roles. 

For example, 47-hospital system Ochsner Health in New Orleans has about 1,200 open nursing positions, Chief Academic Officer Leonardo Seoane said at Thursday’s hearing.

The workforce shortaged led Ochsner to close about 100 beds across its system during the past six months, leading to it use already-constrained emergency departments as holding bays for patients, he said.

Like other systems, labor costs have also been a concern due to a continued reliance on temporary staff to fill gaps. Ochsner’s non-agency labor costs grew just under 60% since 2019, while its costs for contract staff grew nearly 900%, he said.

“Our country is perilously short of nurses, and those we do have are often not working in the settings that could provide the most value,” Sarah Szanton, dean of Johns Hopkins School of Nursing said.

“This was true before the pandemic and has become more acute,” she said.

While many nurses left permanent roles for higher-paying contract positions during the pandemic, others have turned to jobs at outpatient clinics, coinciding with a shift toward non-hospital based care.

Registered nurse employment is nearly 5% above where it was in 2019, with nearly all that growth occurring outside of hospitals, Douglas Staiger, a professor of economics at Dartmouth College, found in his research and said at the hearing.

One major concern: Driving current and projected shortages in hospitals that lawmakers can address is the educational pipeline, medical school and health system leaders said.

Educational programs for nurses and physicians face site shortages and educators who are often allured by other higher-paying jobs in the industry.

Nursing educators in Vermont earn about $65,000 a year — about half of what nurses with similar degrees working in hospitals earn, Sanders said during the hearing. He asked members to consider expanding the Nurse Corps and nurse faculty loan repayments, among other programs.

Supporting partnerships between universities and hospitals to create more training opportunities is another way Congress can help, along with addressing high costs of tuition, James Herbert, president of University of New England, said during the hearing.

“Scholarship and loan repayment programs are critical to make healthcare education more accessible for those who would otherwise find it out of reach,” Herbert said.

That includes expanding and improving Medicare-funded physician residencies, he said.

Creating a more diverse workforce that looks more like the population it serves is another important task, and one lawmakers can address by supporting historically black colleges and universities.

Federal funding could help improve classrooms and other infrastructure at HBCUs “that have been egregiously are underfunded for decades,” in addition to expanding Medicare-funded residencies for hospitals that train a large number of graduates for HBCU medical schools, said James Hildreth Sr., president and CEO at Meharry Medical College in Nashville.

The American Hospital Association submitted a statement to the HELP subcommittee and said it also supports increasing the number of residency slots eligible for Medicare funds and rejecting cuts to curb long-term physician shortages.

Other AHA supported policies to address current and long-term workforce shortages include better funding for nursing schools and supporting expedited visas for foreign-trained nurses.

AHA also asked lawmakers to look into travel nurse staffing agencies, reviving requests it made last year alleging that staffing companies engaged in price gouging during the pandemic.

Last year some state lawmakers considered capping the rate hospitals can pay agencies for temporary nursing staff, though none ended up passing legislation to do so.

Physician burnout reaches record levels 

https://mailchi.mp/3a7244145206/the-weekly-gist-december-9-2022?e=d1e747d2d8

The long hours, stressful conditions, and labor shortages brought on by the pandemic have done serious harm to the physician workforce. The graphic above tracks physician burnout, a combination of emotional exhaustion, loss of agency, and depersonalization that has become the primary measure of the pandemic’s toll on workers, to reveal that physicians are demoralized like never before. 

Physician burnout levels had been decreasing since 2014, in part due to practice consolidation and the expansion of team-based care models. Burnout reached its lowest levels in 2020—perhaps explained by a pandemic-induced sense of purpose—but 2021 then saw a dramatic spike in every measure of physician dissatisfaction, as the heroic glow of the early pandemic faded, and an overtaxed and understaffed delivery system became the new norm.

In explaining how the pandemic has impacted their career decisions, surveyed physicians list unsustainable burnout and stress as their top concern, and 11 percent say they have exited the profession, either for retirement or a non-clinical job, in the past two years. Four in ten surveyed physicians report changing jobs since 2020, mainly within similar or different practice settings, citing a desire for better work-life balance as their primary motivation. (It should be caveated that these data are from a smaller survey of 534 physicians, 40 percent of whom identified as “early career”.) 

While the solutions here aren’t new, they are challenging: we must continue to implement team-based care models that provide physicians top-of-license practice and improved work-life balance, remove administrative tasks wherever possible, and ensure that we are communicating and engaging physicians—employed and independent alike—in organizational strategy and decision-making. 

Why large health insurers are buying up physicians

https://mailchi.mp/3a7244145206/the-weekly-gist-december-9-2022?e=d1e747d2d8

An enlightening piece published this week in Stat News lays out exactly how UnitedHealth Group (UHG) is using its vast network of physicians to generate new streams of profit, a playbook being followed by most other major payers. Already familiar to close observers of the post-Affordable Care Act healthcare landscape, the article highlights how UHG can use “intercompany eliminations”—payments from its UnitedHealthcare payer arm to its Optum provider and pharmacy arms—to achieve profits above the 15 to 20 percent cap placed on health insurance companies.

So far in 2022, 38 percent of UHG’s insurance revenue has flowed into its provider groups, up from 23 percent in 2017. And UHG expects next year’s intercompany eliminations to grow by 20 percent to a total of $130B, which would make up over half of its total projected revenue.

The Gist:

The profit motive behind payer-provider vertical integration is as clear as it is concerning for the state of competition in healthcare

UHG now employs or affiliates with 70K physicians—10K more than last year—seven percent of the US physician workforce, and the largest of any entity. 

Given the weak antitrust framework for regulating vertical integration, the federal government has proven unable to stop the acquisition of providers by payers. Eventually, profit growth for these vertically integrated payers will have to come from tightening provider networks, and not just acquiring more assets. That could prompt regulatory action or consumer backlash, if the government or enrollees determine that access to care is being unfairly restricted.

Until then, the march of consolidation is likely to continue.
