Last year, the federal government spent $20.5 billion overpaying private insurers for Medicare Advantage plans — and the industry’s aggressive lobbying campaign is kneecapping efforts by lawmakers to stop the scheme.
The health insurance behemoth Humana enjoyed a banner 2022. The Louisville, Kentucky–based insurer made $2.8 billion in profits last year, while paying out $448 million in dividends to shareholders and more than $17 million in compensation to its CEO.
The main driver of those earnings? The federal government spent $20.5 billion overpaying Humana and other private insurers for the Medicare Advantage plans they manage on behalf of seniors and people with disabilities. If not for those overpayments, Humana could have suffered a nearly $900 million loss in 2022, according to a Lever analysis.
Humana is the most prominent example of how insurers have built a major cash cow out of systematically overbilling Medicare Advantage, the private Medicare program operated by private interests. These overpayments are symptomatic of a broader profit-driven policy agenda that seeks to completely privatize Medicare, one of the nation’s most popular social programs, and lock program recipients into subpar private insurance plans, even when they get sicker and need the best care possible.
Medicare Advantage plans have higher claim denial rates and more prior authorization restrictions than traditional Medicare plans. Last year, regulators found that nearly one in five payment requests rejected by Medicare Advantage plans in 2018 were wrongfully denied, representing an estimated 1.5 million claims.
And while Biden administration proposals could have helped slow the for-profit takeover by tightening the screws on Medicare Advantage overpayments, insurers recently led a fierce lobbying campaign to dissuade the government from fully cracking down on the practice.
At the root of Medicare Advantage overpayments is “upcoding” by insurers, a scheme by which the companies systematically overbill the public as if their patients are sicker than they really are. Companies have offered bottles of champagne and bonuses to entice doctors to add diagnoses to patients’ records, according to government lawsuits reviewed by the New York Times.
In total, these practices led to $20.5 billion total excess payments to Medicare Advantage insurers in 2022, according to a March report from the Medicare Payments Advisory Commission (MedPAC), a federal body tasked with overseeing Medicare. In the coming years, the overpayment problem could get substantially worse. A November 2021 study suggested that Medicare costs from 2023 to 2031 will be $600 billion higher than if Medicare Advantage beneficiaries were instead enrolled in traditional Medicare.
Because of such overpayments, big insurers like Humana have become highly dependent on Medicare Advantage. Humana, for example, earned more than 80 percent of its revenue from Medicare last year, and now has nearly five million Medicare Advantage customers. Wall Street loves this business model: Humana’s stock has outperformed the S&P 500 by 23 percent over the past five years.
Humana isn’t alone in benefiting from Medicare Advantage overpayments. The other major for-profit insurers — UnitedHealth, Centene, and CVS Health, which owns Aetna, would have seen major hits to their 2022 profits had the government eliminated the overpayments.
UnitedHealth Group would have seen its profits deteriorate by more than one-third, from $14.4 billion to less than $8.8 billion, according to an analysis by the Lever. CVS Health would have seen its profits cut by more than half, from $4.1 billion to $1.9 billion. And Centene would have seen its profits deteriorate by more than one-quarter, from $3.4 billion to $2.4 billion.
Experts say the enormous sums of money going toward overpayments endanger the overall financial stability of Medicare as a whole.
“It’s threatening the solvency of our Medicare trust fund,” said Ana Malinow, a physician active in pro–Medicare for All groups. “The trust fund is made up of payments that people make throughout their entire working lives. If you are working, you’re paying into Medicare every two weeks with your paycheck. Instead of money going to pay for health care for seniors and people with disabilities, it’s going to UnitedHealth and Humana.”
Cutting back Medicare Advantage overpayments could be transformative for the social program, said David Lipschutz, associate director of the Center for Medicare Advocacy, which lobbies for a robust Medicare system. “These are huge amounts of money that could be directed to shoring up Medicare’s finances,” said Lipschutz. “Or expanding benefits for everyone, not just in Medicare Advantage plans.”
The government’s inability to crack down on Medicare Advantage overpayments is a product of major lobbying campaigns by the industry. Two Biden administration proposals that would have tightened the screws on Medicare Advantage overpayments by enhancing audits and cutting the growth of payments to Medicare Advantage plans were both scaled back in the face of aggressive industry lobbying and TV campaigns.
Instead, while there will likely be some cutbacks, the Medicare Advantage gravy train will continue. The number of people enrolled in Medicare Advantage is set to outpace traditional Medicare for the first time ever this year, with more than thirty million beneficiaries.
Better Medicare Profits
In February, the Centers for Medicare and Medicaid Services (CMS), which oversees Medicare, proposed a rule that would have reined in upcoding abuses by reducing extra payments that insurers receive for certain diagnoses, including diabetes “with complications” and a rare form of malnutrition. But in the face of widespread industry lobbying, the agency settled on a weaker three-year phase-in effort.
Even the original proposed rule might not have been enough to address Medicare Advantage overpayments. MedPAC called the initial proposal “insufficient” in a comment letter, and said that Secretary of Health and Human Services Xavier Becerra had “not taken significant action” in response to MedPAC’s analyses of fraudulent billing in Medicare Advantage.
Another way to crack down on upcoding schemes would be to limit government payments to Medicare Advantage plans, since it would send a message to Medicare Advantage providers that overall program costs are far too high. Last December, CMS did so by proposing increasing payments to Medicare Advantage plans by just 1 percent, compared to the 8.5 percent payment increase it approved last year.
In response, the Better Medicare Alliance, an advocacy group for Medicare Advantage plans, spent at least $13.5 million on ads pressuring the administration to increase the planned rate hike.
The group also spent $570,000 lobbying Congress in the first quarter of this year, nearly double the $330,000 spent in the prior quarter. All told, the four major publicly traded health insurance companies that operate Medicare Advantage plans, as well as the insurance lobby America’s Health Insurance Plans, spent nearly $19 million on federal lobbying in the first quarter of 2023, a 66 percent increase from the prior quarter, according to a Lever analysis of data from OpenSecrets.
The government’s inability to crack down on Medicare Advantage overpayments is a product of major lobbying campaigns by the industry.
That lobbying paid off: instead of a 1 percent increase in payments to Medicare Advantage — which the insurance industry cast as a reduction because the growth rate had slowed dramatically — CMS announced a 3.3 percent payment increase at the end of March.
“The industry’s aggressive lobbying campaign showcases that they clearly want to protect their profit stream,” said Lipschutz. “Their disingenuous campaign tried to paint some very minor payment adjustments as being catastrophic to the Medicare Advantage program. They tried to ‘Medi-scare’ beneficiaries into contacting their elected officials to get CMS to back off — which CMS did to a certain extent.”
While industry analysts have said that this modest rate increase will strain insurers’ prodigious profits, the bond ratings agency Moody’s declared in April that “we believe [Medicare Advantage] will continue to be a growth driver for the industry and will take further market share from traditional Medicare.”
Medicare Advantage payment increases like Joe Biden’s 3.3 percent hike will result in higher dividends to shareholders at the expense of the solvency of traditional Medicare.
The insurance industry also took aim at a recently proposed rule to claw back years of inflated risk adjustment payments, which are made to incentivize Medicare Advantage plans to accept riskier patients.
Initial proposals floated by CMS included retroactive audits of risk adjustment payments going back to 2011. Instead, the final pared-back proposal released in March only included retrospective audits going back to 2018.
Lipschutz said he does give the administration some credit for the audit rule change and the smaller rate hike for Medicare Advantage insurers relative to the prior year.
“On the other hand, it can be seen as far too little too late,” he said, adding that federal policy being so weighted toward Medicare Advantage plans at the expense of traditional Medicare is a “serious imbalance that is long overdue for course correction.”
Traditional Medicare operates on a fee-for-service basis. This means that doctors and hospitals are paid directly by Medicare for the services they provide. Private plans have operated as part of Medicare since just after the program was launched in 1965, but typically did so on a very limited basis. That changed in 2003, when Congress substantially increased subsidies for plans to enter the market, after intense industry lobbying.
While the traditional Medicare model is not without problems — Medicare only covers 80 percent of expenses, which means that seniors need either Medicaid or a Medigap insurance plan to get full coverage — it has major benefits relative to Medicare Advantage.
The principal benefit of traditional Medicare is that there is not a profit-driven insurer attempting to limit the scope of care that a patient needs.
Medicare Advantage “seems like a good idea,” said Ted Doolittle, the State Health Care Advocate for Connecticut. That’s because Medicare Advantage plans often offer expanded benefits like dental, vision, or wellness. They also eliminate the need for a potentially expensive Medigap plan if a senior isn’t eligible for Medicaid coverage.
But then, said Doolittle, “The scholarship shows that when patients get sick, they try to go back to traditional Medicare.”
According to Doolittle, most people who are either Medicaid eligible or who could afford a Medigap plan would balk at signing up for Medicare Advantage plan “if folks had adequate information about the nature of Medicare Advantage versus traditional Medicare, and the higher denial rates and the prior authorizations required for care in Medicare Advantage.”
Doolittle pointed out that there’s a key barrier to patients to getting full medical coverage if they try to switch back to Medicare once they become sick: in most states, Medigap insurers are allowed to discriminate against seniors on the basis of preexisting conditions if they are already enrolled in Medicare Advantage, something that is prohibited when seniors first become eligible for Medicare three months prior turning sixty-five.
This problem is amplified by the rapid growth of Medicare Advantage. In 2010, a little over one-quarter of Medicare beneficiaries were in Medicare Advantage. By 2016, it was still less than one-third. But this year, a majority of Medicare beneficiaries will be on the private plans.
And the exorbitant government costs of Medicare Advantage are not limited to just overpayments related to upcoding. This year, Medicare Advantage plans will receive taxpayer rebates averaging $196 per participant. These rebates have more than doubled since 2018.
The total cost of the rebates could be as high as $75 billion this year, according to analysis by Bill Kadereit, president of the National Retiree Legislative Network.
“The extra $196 is spent on fringe benefits, and only on fringe benefits that go towards Medicare Advantage beneficiaries,” Kadereit said. “The other 30 million people in traditional Medicare get nothing. When Joe Manchin in West Virginia says ‘I like sending money to the Medicare Advantage plans, give them more,’ well, 40 percent of his people in West Virginia are not on Medicare Advantage, so they don’t get a nickel.”
Expanded attention to Medicare Advantage abuses has led some members of Congress to speak up and pressure the Biden administration to rein in the industry, even in the face of aggressive lobbying.
In February, seventy lawmakers, led by Congressional Progressive Caucus chair Pramila Jayapal (D-WA), sent a letter to the Biden administration pointing out that “as enrollment in [Medicare Advantage] grows, spending per beneficiary has grown faster in [Medicare Advantage] than original Medicare, and that spending is being funneled into corporate profits under the guise of operating costs instead of into care for patients.”
That said, there is no voice in Congress advocating for the phasing out of Medicare Advantage and allocating expanded benefits equally to all Medicare beneficiaries, which is by far the most cost-effective option.
And the larger Medicare Advantage becomes, the more politically difficult it will be to rein in, noted Doolittle. “As Medicare Advantage keeps getting more embedded in Medicare, the situation keeps getting worse,” he said. “It’s gotten up to a real critical mass at this point, which makes it very hard to stop.”
