Where Does the Health Insurance Premium Dollar Go?

By Uwe Reinhardt, Ph.D.
The JAMA Forum, April 25, 2017

In early March, America’s Health Insurance Plans (AHIP), the national association of private US health insurers, released an interesting report that presents, for insured patients younger than 65 years, financial statistics for 2014 of commercial and nonprofit health insurance companies.

According to the report, “Where Does Your Premium Dollar Go?,” an average of 79.7 cents per premium dollar is spent by insurers on health care proper and 17.8 cents on the insurers’ “operating costs,” leaving only 2.7 cents per premium dollar as profits.

The nearly 80 cents per premium dollar that insurers report to spend on medical expenses are known in insurance jargon as the “medical loss ratio (MLR),” because it is the portion of premiums collected health insurers “lose” to physicians, hospitals, and other entities who offer health care.

The Affordable Care Act (ACA) mandated an MLR of at least 85% for large insurance companies and of at least 80% for smaller carriers. By their own admission, insurers selling policies for individually purchased health insurance before the ACA went into effect tended to have MLRs in the 55% to 65% range. Should a repeal of the ACA entail elimination of the mandated minimum MLRs, the market might well revert again to these extraordinarily low payouts of premiums for health care.

As already noted, the AHIP reports that insurers had an average profit margin (net profits divided by premium revenue) of only 2.7%. The number seems low, perhaps because it is a simple average. Profit margins for the larger US health insurers, for example, actually were much higher  than just 3% in recent years, with 4.7% for Aetna, 7.0% for Cigna, and 4.6% for United Health Group in 2015 and 3.5% for Anthem in 2014. (These numbers, however, also include the Medicare Advantage program for older people.)

But even a profit margin of 5% belies the frequent assertion that private health insurers divert huge fractions of their premiums to their own profits. Much more troublesome is the 18 cents per premium dollar reported to cover the insurers’ “operating costs.” These include the cost of marketing, determining eligibility, utilization controls (eg, prior authorization of particular procedures), claims processing, and negotiating fees with each and every physician, hospital, and other health care workers and facilities.

These operating costs are about twice as high as are the overhead costs of insurers in simpler health insurance systems in other countries. A 2010 study comparing per capita health spending in Canada and the United States, for example, found that administrative costs in 2002 accounted for 39% of the total per capita spending difference between the 2 countries.

Also worthy of note is that the 18 cents per premium dollar that insurers report as their “production costs” exclude 2 additional forms of administrative overhead. First, the number excludes the value of the time US patients must spend dealing with insurers, mainly over enrollment and over claims. It can be very time-consuming. Second, the insurers’ cost naturally excludes also the sizeable outlays that physicians, hospitals, and other health care workers and facilities make to negotiate prices for health care and to argue over medical bills.

A Costly “Coding War”

A “must read” in this regard is a recent article by Elizabeth Rosenthal, MD, “Indecipherable Medical Bills? They’re One Reason Health Care Costs So Much.” Rosenthal describes a costly “coding war” in which physicians, hospitals, and others who treat patients seek to maximize their profits by hiring legions of consultants who know how to “upcode” procedures in their medical bills. For their part, insurers hire legions of coding consultants who know how to protect insurers from such upcoding. Rosenthal vividly describes how individual patients can get mauled in the process.

We can think of the extraordinarily high overhead imposed on insured individuals and patients in the United States as the price they seem to be willing to pay for the privilege of choice among health insurers and, for each insurer, among multiple different insurance products. US consumers seem so fanatic about this choice that to keep it, they have been willing to give up their erstwhile freedom of choice among physicians, hospitals, and other clinicians and health care facilities. Citizens of most other countries have made that trade-off in exactly the opposite direction.

Medicaid Block Grants and Federalism; Lessons From Canada

Benjamin D. Sommers, M.D., Ph.D.; C. David Naylor, M.D., D.Phil.
JAMA, April 25, 2017

Republican leaders are proposing a fundamental reform in Medicaid financing—a shift to block grants. Instead of a matching subsidy and federal oversight, block grants would give states an annual lump sum with minimal conditions attached.

Block granting for social and health programs has been used with varying levels of success in welfare reform and in a modified version for the Children’s Health Insurance Program (CHIP), which provides federal matching funds up to a specified cap. But for such a large state-federal health insurance program, perhaps the most useful precedent is Canada, which made a similar shift to block grants several decades ago.

Canada’s Block Grant Experience

Canada’s health insurance system has been a joint federal-provincial initiative since the 1950s. Individual provinces enacted single-payer systems for hospital care and medical services between 1947 and 1962. The federal government implemented a 50% subsidy to support provinces’ universal coverage policies for hospital care in 1957 and extended this approach to physician services in 1968.

Costs of hospital and physician services escalated steadily across Canada in the 1970s. By that time, most provinces had extended public insurance to prescription drugs for low-income and elderly residents, partial coverage for home care and long-term care, and a mix of other services. Facing low economic growth and rising deficits, the federal government first capped the growth rate in its share of spending and then retreated from a match rate altogether. By 1977, block grants had been implemented. In doing so, the federal government agreed to give provinces an increased share of income tax revenues from their residents. Since then, 2 central issues in the current US debate—restraining the federal cost of Medicaid and giving states more control—have played out in Canada.

The primary long-term effects have been a downsizing of federal spending on health care and increasing strain on provincial budgets. The federal government reduced its spending in 2 ways. First, ending the 50% match uncoupled federal commitments from growth in health care spending; more specifically, the government capped the annual growth rate for the grants starting in 1986, sometimes freezing the growth rate entirely and other times setting it at 2% to 3% below per capita GDP growth. Second, one-time cuts to the block grants were made, amounting to 5% in 1982-1983, followed by a 30% reduction in health and social block grants in the mid-1990s. Overall, the proportion of provincial health spending derived from federal transfers declined from approximately 30% in the late 1970s to less than 15% by the mid-1990s.

Pushback from the provinces has resulted in some gains in recent decades. Once the economy recovered in the late 1990s, several short-term increases in the block grants were negotiated with earmarks for elements such as primary care reform, improved home care, and reduction of surgical waiting lists. In 2004, the Liberal federal government committed to a sizable increase in the annual growth rate to 6%. A Conservative government took office in 2006 and initially sustained that rate, but later announced that the annual growth rate would decrease in 2017 to either 3% or the per capita GDP growth rate, whichever was higher. When the Liberal party regained power in late 2015, it adopted the same position, albeit softened by modest one-time earmarks for home care and mental health.

Lessons for the United States

Block granting of social programs is not inherently good or bad. Rather, it is a policy associated with specific economic and political trade-offs. Increased local control and predictability for the federal budget come at the risk of increased cost-shifting to states or provinces. That, indeed, is the Canadian experience. Once block funding was initiated in 1977, health care funding became a line item in the federal budget that could be arbitrarily cut or capped for fiscal or political reasons, as opposed to a level of spending pegged to the needs and health care use of the population. Importantly, these cuts occurred under both conservative and liberal federal governments. The federal share of provincial spending today remains substantially lower than in the 1970s.

There is little evidence that the alleged advantages of block grants have materialized in Canada. Advocates argue that with greater flexibility and proper incentives, states can reduce costs by improving the efficiency of care. In Canada, however, the provinces’ primary means of coping with budget pressures under block grants has been to reduce funding to hospitals and bargain harder with provincial medical associations. Ironically, then, if this scenario plays out in the United States, it would exacerbate one of the chief Republican criticisms of Medicaid—that it pays clinicians such low rates that they have reduced incentives to care for low-income patients. In Canada, the effect of low payment rates to clinicians on care of low-income patients is blunted because federal and provincial legislation has effectively banned private insurance for publicly insured services; hospitals and clinicians accordingly have no choice but to participate. The situation is far more precarious in Medicaid precisely because the US market is segmented with multiple private payers. Facing steep payment cuts, many US physicians and hospitals would likely stop providing care for Medicaid patients entirely. Another likely scenario in the United States is that a block grant system would simply lead many states to restrict eligibility for Medicaid, leaving millions of low-income adults and children newly uninsured.

In conclusion, the Canadian experience suggests that a block grant policy for Medicaid is most likely to succeed in only one aspect—reducing federal spending on the program. It would do so by shifting costs to states and forcing untenable trade-offs that would limit access to care for low-income US residents. Although Canada has often been seen as a panacea for US liberals desiring a single-payer approach to health insurance, perhaps the most useful lesson from north of the border for the current policy debate is a demonstration of how a conservative policy model—block grants—may be a risk not worth taking.

Republicans intend to change the financing of Medicaid to giving states an annual lump sum – block grants. The primary purpose is to reduce the federal contribution to state Medicaid programs, placing more of the burden on the states – a problem for residents of states with high poverty levels or with stingy governors and legislators.

Today’s message explains the experience with block grants in Canada wherein the supposed advantages of block grants failed to materialize, and each province has ended up bearing more of the costs. The United States would be wise to avoid that same outcome with our Medicaid program.

There is another lesson for single payer advocates. Block grants were used in Canada to shift costs from the federal government to each provincial single payer system. Having a single payer system in place is not enough. Continual vigilance and citizen action is essential. We cannot allow our government to be controlled by people who do not believe in government.

This one unbelievably expensive Iowa patient makes the case for single-payer healthcare

By Michael Hiltzik
Los Angeles Times, April 24, 2017

Back in mid-2016, Iowa customers of Wellmark Blue Cross Blue Shield, the dominant company in the state’s individual insurance market, got a shock: Premium increases of 38% to 43% were in store for many of them for this year.

Three weeks ago they got a bigger shock: Wellmark was pulling out of Iowa’s individual market entirely, leaving the state with one company selling individual policies. Wellmark placed some of the blame on congressional Republicans’ failure to come up with a coherent repeal plan for the Affordable Care Act, leaving plans for 2018 in legislative limbo. With Wellmark’s departure, Iowa’s individual market may be down to a single insurer next year.

But Iowa has another problem that appears to be unique for a state its size: one single state resident whose care costs $1 million a month. That’s enough to all but destroy an individual insurance market that comprises about 30,000 customers. Indeed, that one patient’s care, according to Wellmark, was responsible for 10 percentage points of the 43% premium increase this year.

The important aspect of the Iowa case is what it tells us about the importance of spreading risk in the healthcare market, and the limitations of the Republican nostrum of segregating seriously ill patients into high-risk pools. The idea is to keep their costs from driving up everyone else’s premiums.

The case also points directly to the benefits of a single-payer healthcare system. “The idea of single-payer is that there’s just one risk pool,” says Steffie Woolhandler, a New York physician who is co-founder of Physicians for a National Health Program, the nation’s leading advocacy group for single-payer healthcare. “That’s what makes the care of very high-cost patients affordable.”

High-risk pools and reinsurance funds tend to be hopelessly underfunded. This was the case in most of the 35 states with high-risk pools prior to the Affordable Care Act, including California. Without sufficient public funding to cover all their high-cost residents adequately, most imposed waiting lists for coverage, time limits on eligibility, and premiums so high that many patients couldn’t afford them at all. The proposals for high-risk pools coming from congressional Republicans are similarly stingy.

“What high-risk pool could tolerate a patient costing a million dollars a month?” asks Woolhandler. “It would have to be a huge pool.”

The only fair and effective way to manage such patients, especially the few with truly stratospheric medical costs, is to make them part of a nationwide pool. A risk pool on that scale would represent the functional equivalent of single-payer healthcare. And that’s leaving aside some of the other virtues single-payer advocates cite, including the ability to negotiate prices on pharmaceuticals with the bargaining power of the entire country, and the virtual elimination of insurance company and provider billing office overhead.

The healthcare cost crisis is spreading nationwide, which makes it a national problem demanding a national — meaning a federal — solution.

Perhaps the most fundamental principle of health insurance is to pool risk – the high costs of the few are distributed amongst all participants in the pool. Since health care has become so expensive, distributing costs has made each person’s share – the insurance premium – unaffordable for many.

The Republican proposal to establish high-risk pools is simply a proposal to break up the existing pools into larger pools of the healthy which would then make their insurance premiums more affordable, and small pools of individuals with higher medical costs – the high-risk pools. But these high costs spread amongst fewer individuals would require exorbitant premiums that only the wealthiest individuals could afford, if even them (covering a-million-dollar-a-month patients?).

So how do you pay for the care for individuals in the high risk pools? Well, we have experience with that in the form of state-level high-risk pools and the answer is that you don’t pay for them. These pools were tremendously underfunded, so much so that the states covered only about one-tenth of the otherwise-eligible high-risk population, and those who were covered had very spartan benefits leaving them exposed to much of the costs.

Would the Republicans get serious with their high-risk proposal and fund it adequately? The House Republican Study Committee proposed $50 billion seed money for the states with contributions to the state pools of $2.5 billion per year for ten years. For perspective, the care for the 20 percent of individuals who use 80 percent of our national health care – all of the high-risk individuals in the nation – costs about $2830 billion (national health expenditures for 2017: $3,539 billion), indicating the enormity of the high-risk problem. Of course, many high-risk patients are already covered in other risk pools – Medicare, Medicaid, the VA, employer-sponsored plans, etc. – but the residual who are covered by non-group plans is about 7 percent of the total, and 8o percent of that would be about $200 billion per year – almost 100 times what the Republicans propose. Basically, they are unwilling to fund the high-risk pools they tout.

The larger the risk pool, the greater and more assured is the dilution of risk. Of course, a national single payer system would use a single universal risk pool. As Michael Hiltzik says, it is a “a national problem demanding a national — meaning a federal — solution.” One risk pool for all.

California’s Golden Healthcare Opportunity

By Paul Y. Song, M.D.
The Huffington Post, April 24, 2017

The Affordable Care Act (ACA) commonly known as Obamacare expanded healthcare coverage to approximately 4.6 million Californians and cut the uninsured rate in the Golden state from 16% in 2013 to 8.6% in 2016.

Despite over 60 attempts by Republicans under President Obama to repeal the ACA, and one recently botched effort under President Trump, the overall threat of a radically weakened ACA remains, placing the healthcare of millions of Californians at constant risk. It also leaves California in a constant state of financial uncertainty with regard to its aggressive Medicaid expansion.

Yet, event without any GOP repeal, 2.9 million Californians remain uninsured, of which a third are undocumented, 75% are from communities of color, and approximately 250,000 are kids.

Because most of the ACA was largely written by the private insurance and pharmaceutical industries, the ACA had no provisions to regulate health insurance premiums or rising prescription drug costs. As a result insurance premiums have increased roughly 200% in the past 10 years in California and a recent Kaiser Family Foundation study shows that the number of insured Americans that have trouble affording their premiums has increased from 27 to 37 percent since 2015, while the number of folks who have trouble with their deductibles has increased from 34 to 43 percent.

Meanwhile, one in 10 seniors cannot afford their prescriptions and one-third of all insured Americans delay seeking care because they cannot afford their co-pays and deductibles, while medical illness remains the number one cause of bankruptcies.

To date, Covered California has one of the most limited exchanges in the country in terms of having 75% of all their plans with very narrow networks (patients have access to 25% or less of physicians in a defined area). And premiums for 2017 jumped an average of 13.2%, three times the increase within the past two years.

Healthcare benefits remain a major source of labor negotiation strife as workers are being forced to contribute more towards their own healthcare while companies are handcuffed by skyrocketing premiums, which leave less money for capital improvements and their own R&D.

And, California has a $150 Billion unfunded retiree healthcare liability that has never been addressed.

California’s fragmented multi-payer system takes upwards of 20 cents of every healthcare dollar away from actual patient care to spend towards administrative costs often used to deny care, marketing, overheard, and executive compensation. A 2005 study by the Lewin Group revealed that a “single payer” system rather than multiple insurers to oversee funding of a private healthcare delivery system would save California a minimum of $20 Billion in the first year alone in administrative savings. At the same time it would expand coverage to care for everyone without requiring massive new taxes or spending.

A 2016 study from the UCLA Center for Health Policy Research revealed that 71% of all healthcare expenditure in California in 2016 was paid for by taxpayers. Coupled with the previously mentioned administrative waste, Californians are essentially paying for universal healthcare, just not getting it.

So what is California to do?

The fact is that our legislators can no longer turn a blind eye while California remains hostage to a federal government run by a heartless majority who recklessly controls the purse strings in favor of tax cuts for the 1% while refusing to view healthcare as a right. As the 6th largest economy, California needs to think boldly and look at what all major industrialized nations do.

The answer has been there all along.

California Senate Bill 562, authored by Senators Ricardo Lara and Toni Atkins calls for a California Single Payer program. While some specifics still need to be worked out especially with regard to obtaining a federal waiver to incorporate Medicare, Medicaid, and S-Chip funds, it is clear that any such program already faces tremendous opposition from corporatist legislators.

In order to get a healthcare program for the people, it must come from an unprecedented groundswell by the people. We must hold our elected officials publicly accountable and demand what we are already paying for and readily deserve. The ACA pointed our state and nation in the right direction, but the time for real universal healthcare is now and the opportunity to do so is golden and now!

Paul Song’s article is particularly helpful in understanding the health care reform challenge before us in that it describes one of the most successful programs in the nation – California’s – while noting the gross inadequacies of reform limited by our current federal laws and regulations. The best we have – a meticulous implementation of the Affordable Care Act – still leaves us far too short of judicious reform.

As co-chair of the Campaign for a Healthy California, Song supports the latest effort to enact a single payer system in California – Senate Bill 562 – while acknowledging that difficulties remain in attempting to incorporate Medicare, Medicaid and S-CHIP funds into the state program. But he also acknowledges that the federal government is now under the control of politicians who do not support guaranteeing essential health care services for all.

So what is California to do? Move forward with health care reform on both fronts. Advance the state single payer agenda behind SB 562, taking it as far forward as the federal politicians and courts will allow. But even more important is to join with other states to  change the federal political agenda so that everyone in the nation can have affordable  health care, and then even Californians will not be limited by federal restrictions.

Whatever it is, if it is for the good of patients, be there and do it, but always keep in mind that this is for everybody, so don’t leave anyone behind.

Catastrophic Health Expenditure Risk Among Uninsured Trauma Patients in the United States

By Scott, John W. M.D., M.P.H.; Raykar, Nakul P. M.D., M.P.H.; Rose, John A. M.D., M.P.H.; Tsai, Thomas C. M.D., M.P.H.; Zogg, Cheryl K. M.S.P.H., M.H.S.; Haider, Adil H. M.D., M.P.H.; Salim, Ali M.D.; Meara, John G. M.D., D.M.D., M.B.A.; Shrime, Mark G. M.D., M.P.H., Ph.D.

Abstract

Objective: To characterize the economic hardship for uninsured patients admitted for trauma using catastrophic health expenditure (CHE) risk.

Background: Medical debts are the greatest cause of bankruptcies in the United States. Injuries are often unpredictable, expensive to treat, and disproportionally affect uninsured patients. Current measures of economic hardship are insufficient and exclude those at greatest risk.

Methods: We performed a retrospective review, using data from the 2007-2011 Nationwide Inpatient Samples of all uninsured nonelderly adults (18-64 yrs) admitted with primary diagnoses of trauma. We used US Census data to estimate annual postsubsistence income and inhospital charges for trauma-related admission. Our primary outcome measure was catastrophic health expenditure risk, defined as any charges >=40% of annual postsubsistence income.

Results: Our sample represented 579,683 admissions for uninsured nonelderly adults over the 5-year study period. Median estimated annual income was $40,867. Median inpatient charges were $27,420. Overall, 70.8% of patients were at risk for CHE. The risk of CHE was similar across most demographic subgroups. The greatest risk, however, was concentrated among patients from low-income communities (77.5% among patients in the lowest community income quartile) and among patients with severe injuries (81.8% among those with ISS >= 16).

Conclusions: Over 7 in 10 uninsured patients admitted for trauma are at risk of catastrophic health expenditures. This analysis is the first application of CHE to a US trauma population and will be an important measure to evaluate the effectiveness of health care and coverage strategies to improve financial risk protection.

Uninsured with traumatic injuries may be cured into destitution

By Ronnie Cohen
Reuters, April 20, 2017

When a badly injured patient rolls into the emergency room, Dr. John Scott doesn’t ask to see proof of insurance. Instead, he immediately begins treatment.

Hospital care frequently saves patients from gunshots, stab wounds, crushing car accidents and other traumatic injuries. But Scott found in a new study that 7 out of 10 adult uninsured trauma patients suffer another debilitating injury: financial catastrophe.

“We’re getting better at trauma, and they’re going home financially ruined,” Scott said in a phone interview.

“There’s nobody we turn away for emergency trauma care. We don’t check people’s insurance status. We don’t check their wallet,” he said. “If everybody is deserving of world-class trauma care, everybody is deserving of protection from financial catastrophe from that care.”

Dr. David Himmelstein, a professor at the City University of New York’s Hunter College School of Public Health, described the study as “quite sophisticated.” It “paints an extraordinarily disturbing picture of America’s vulnerability,” he said in an email.

“This study shows that someone who is in a car accident, or is mugged, or experiences sudden trauma for some other reason, risks being driven to financial ruin,” he added.

“In essence, unless you’re Bill Gates, you could be at risk of financial catastrophe if you fall seriously ill,” said Himmelstein, who was not involved with the study.

We hear often of healthy individuals remaining uninsured because of the very high cost of health insurance, but it is a risk that they are willing to take because they have very few health care needs…though they hope nothing really bad happens. Well, bad things do happen, and this study confirms that 70 percent of those who lost the bet face destitution.

The intent leading up to health care reform was that everyone would be covered. But, as the Affordable Care Act was crafted, it became obvious that the design in putting together various public and private programs was not seamless, and could never be. Thus it was accepted that millions would remain uninsured (28.5 million under 65 as of Sep 2016 – KFF), unless we were to do single payer or something like that, but, of course, that wasn’t feasible, so they said.

More patches could be added to the system but only at higher marginal costs, requiring a major expansion of our wasteful administrative burden, and yet it would still fall short. The deficiencies of the Republican proposals have been exposed by their own rhetoric – that it’s about “access” (but not about actually financing insurance or health care). Their proposals would only increase the numbers of uninsured.

Today’s report shows that relying on current good health and hoping for the best in the future is not a satisfactory approach. As study coauthor Dr. John Rose indicates, absolutely everyone is entitled to our world-class trauma care, and yet they are not entitled to protection from financial catastrophe from that care. We have to change that.

It has become obvious that a single payer national health program is the only feasible approach for the United States that would not only guarantee access to care but would also finance it for everyone. The patchwork models just don’t work, and are too expensive anyway.

Believe me. Take a few minutes (9 to be precise), and read this (at link above). Then send it to others and strongly recommend that they read it, and then have them send it on to yet others who might also care. This needs to go viral.

Substantial Physician Turnover And Beneficiary ‘Churn’ In A Large Medicare Pioneer ACO

By John Hsu, Christine Vogeli, Mary Price, Richard Brand, Michael E. Chernew, Namita Mohta, Sreekanth K. Chaguturu, Eric Weil and Timothy G. Ferris
Health Affairs, April 2017

Abstract

Alternative payment models, such as accountable care organizations (ACOs), attempt to stimulate improvements in care delivery by better alignment of payer and provider incentives. However, limited attention has been paid to the physicians who actually deliver the care. In a large Medicare Pioneer ACO, we found that the number of beneficiaries per physician was low (median of seventy beneficiaries per physician, or less than 5 percent of a typical panel). We also found substantial physician turnover: More than half of physicians either joined (41 percent) or left (18 percent) the ACO during the 2012–14 contract period studied. When physicians left the ACO, most of their attributed beneficiaries also left the ACO. Conversely, about half of the growth in the beneficiary population was because of new physicians affiliating with the ACO; the remainder joined after switching physicians. These findings may help explain the muted financial impact ACOs have had overall, and they raise the possibility of future gaming on the part of ACOs to artificially control spending. Policy refinements include coordinated and standardized risk-sharing parameters across payers to prevent any dilution of the payment incentives or confusion from a cacophony of incentives across payers.

From the Introduction

Recently, the Centers for Medicare and Medicaid Services (CMS) announced intentions to move half of all Medicare payments away from traditional fee-for-service reimbursement by 2018 and toward alternative payment models, such as those exemplified by the accountable care organization (ACO) program.

Using a combination of organizational and Medicare data, we examined the distribution of beneficiaries in a Pioneer ACO across affiliated physicians, the magnitude of physician changes from year to year, and the impact of physician changes on an aligned beneficiary population.

From the Discussion

There are two important findings. First, not all physicians had attributed beneficiaries, and those who did had relatively few ACO beneficiaries, on average. This limited ACO penetration at the physician level could mitigate the ACO’s potential to achieve its financial targets, at least for any effects mediated through physician behavior. With the small numbers, it is not surprising that the distribution of high-spending beneficiaries also is skewed such that a few physicians appeared to have the sickest beneficiaries, while many appeared to have mostly beneficiaries with modest spending.

Second, we found evidence of substantial changes in the affiliation status of physicians with respect to this large Pioneer ACO, which were associated with changes in numbers of beneficiaries aligned and could affect the predicted spending for the ACO beneficiary population. New physician affiliations accounted for only half of the growth in the ACO beneficiary population over time. In short, the physician changes appeared to affect the composition of the ACO beneficiary population, which could have important implications for the ACO program’s overall financial impact.

With higher physician reimbursement and explicit CMS goals associated with alternative payment models, it is likely that the impetus will only increase for physicians to join ACOs. ACOs’ ability to deliberately select participating physicians year to year, however, creates a relatively simple mechanism to “game” the risk pool. For example, in our sample, dropping the twenty-two primary care physicians (top 5 percent) with the most high-spending beneficiaries (spending more than $81,000) would reduce the mean Medicare ACO spending per beneficiary by 17 percent.

The presence of this mechanism and the ease of its use, especially compared to the more difficult task of redesigning care, could result in an undesirable but powerful temptation for ACOs, particularly those facing financial constraints or pressing financial motivations. Indeed, the push to increase ACO incentives now that the program is in its fifth year could exacerbate this concern.

From the Conclusion

As the pace and magnitude of reform grow, we might expect that the potential impact on physicians’ behavior could increase but that the amount of organizational change also could accelerate, thus creating the potential for mischief.

By Don McCanne, M.D.

Under the MACRA replacement for the flawed SGR method of determining Medicare payments, CMS is moving forward with shifting the delivery system into alternative payment models, the predominant model being the accountable care organization (ACO). This study of one of the premier ACOs in the nation (Partners HealthCare) should make us question whether such a shift is wise policy.

Briefly, this study shows that there is considerable instability in the professional relationships of physicians and patients due to considerable churning in both professional employment and patient enrollment in ACOs. Also, ACO patients are a small percentage of the physicians’ patient populations and thus provide little motivation for the delivery model improvements that some in the policy community say would be inevitable in the drive to higher quality and lower costs that the ACO model supposedly promotes. Further, as this article explains, the ACO organizational change creates “the potential for mischief.” Flags should go up.

When we want to save money, improve quality and improve the physician/patient relationship, this does not seem to be the right model to pursue. In contrast, changing to a well designed single payer system improves efficiency while establishing long term professional relationships. The policy community should be working on that model instead – an improved Medicare for all.
