“Almost half of people on Medicare, 31 million Americans, are now enrolled in a Medicare Advantage plan, nearly double the share of 10 years ago. It is widely assumed that Medicare Advantage will cover a majority of the program’s beneficiaries within the next few years.”
…
“Medicare Advantage allows private insurers to offer their own plans that provide Medicare benefits as well as some additional perks not available in the original program. The secret to the program’s success is simplicity. Traditional Medicare is a fragmented program; Part A covers hospital care and Part B covers outpatient services. Patients must enroll in a separate Part D plan for prescription drug coverage that is administered by private insurers. Most people also purchase supplemental coverage, extra insurance that helps reduce their out-of-pocket costs.
Medicare Advantage, also known as Part C, combines those benefits into one insurance plan that also includes an annual limit on out-of-pocket costs, something that does not technically exists in regular Medicare.
But the benefits to patients seem to come at a cost to taxpayers. Though the health insurance industry disputes these findings, MedPAC, the independent committee tasked with overseeing Medicare on Congress’s behalf, found Medicare Advantage plans cost the federal government more money per patient than the original program would have if those same people had stuck with the traditional benefits.
Private companies are also making healthy margins on their Medicare business.”

“Medicare Advantage enrollees are more likely to report trouble affording health care than people on traditional Medicare. Some of the behavior by Medicare Advantage plans, such as using AI to decide when to stop covering services for their enrollees, may be becoming more common in the private sector but is still unheard of for public programs.
The trade-off the United States seems to be making is accepting more administrative bloat and more stringent provision of benefits in exchange for a more navigable Medicare plan. The trade-off is one other countries have made as they designed universal health care programs. (A similar trend is underway in Medicaid.)
But as concern grows about Medicare facing a potential financial cliff, and evidence mounts about the costs of Medicare Advantage, the risks of the trade-off are becoming clearer. Medicare is no longer what it used to be: Once the epitome of government-run health insurance, its benefits are on the verge of being primarily funneled through private companies. Any attempts to change the program will have to wrestle with that reality.”
…
“In traditional Medicare, for example, patients can go to any doctor or hospital that accepts Medicare; Medicare Advantage has more limited provider networks, and patients can be on the hook for higher costs if they are treated at an out-of-network doctor or hospital.
The federal government pays Medicare Advantage plans a flat rate for the expected cost of covering their particular customers and the insurers are required to adhere to certain rules about benefits and costs. But companies still have flexibility about how to run their plans and have a financial incentive to limit expenses. The less money they spend, the more they get to keep for themselves.
Still, customers will vote with their feet and, after slower-than-expected initial uptake, Medicare Advantage is now growing so quickly that it will soon be the dominant form of Medicare.”
…
“The premiums people pay for a Medicare Advantage plan can be significantly lower than the combined cost of supplemental coverage and a Part D plan — less than $50 compared to more than $200 on average, per Terry and Muhlestein — with the added benefit of having only a single insurance card. According to a 2022 Commonwealth Fund survey, the additional benefits offered by Medicare Advantage plans (such as dental or vision) and the limits on out-of-pocket costs were the most common reasons seniors gave for choosing the alternative over the original program.”
…
“Medicare Advantage patients are less likely to receive medical care at the highest-rated facilities for their particular needs, compared to people with traditional Medicare, a reflection of more restrictive provider networks.”
…
“A report from federal investigators published in April 2022 found that tens of thousands of Medicare Advantage customers were denied coverage for services they should have been entitled to. A significant number of prior authorization denials (13 percent) and payment denials (19 percent) reviewed by the investigators were for services that should have been covered by the program but were not.”
…
“According to MedPac, since 2004, Medicare has always paid more to Medicare Advantage plans for the cost of covering their customers than the program would have spent if the same beneficiaries had instead been enrolled in traditional Medicare. Some years, the private plans were receiving a nearly 20 percent markup compared to the original benefit structure.”
…
“The growth of Medicare Advantage is contributing to the financial crunch. Those plans receive funding based on the type of service provided to their customer, which means money for hospital care comes from Part A. Annual Part A payments to Medicare Advantage plans are expected to increase from about $176 billion in 2022 to $336 billion by 2030.
With revived concerns over Medicare’s solvency and evidence of excess spending in Medicare Advantage, policymakers are starting to look at making changes to the program. But that won’t be easy.”
…
“States have outsourced much of the administration of Medicaid to managed care plans. Countries like the Netherlands have set up health systems that use private insurers, operating under strict government oversight, to provide insurance benefits to their citizens. Giving people more choice and a more streamlined experience can have its benefits, as evidenced by the popularity of Medicare Advantage in the US.
But asking private actors, with profit motivations, to administer government benefits to which people are supposed to be entitled brings risks. People are more likely to have trouble affording health care and their claims are more likely to be denied; that is true in places like the Netherlands, compared to other countries with more direct government administration, and that is true of Medicare Advantage when compared to the traditional Medicare program.”
