Traditional Medicare versus Medicare Advantage

City workers in NYC are getting a raw deal or some would call it a better deal (if you are the city) on healthcare when one retires. There must be some type of deal going on here. Medicare Advantage does have its coding issues and smaller sources of healthcare places a member can go to. Typically, it is local care from a limited poor of care givers.. Traditional Medicare allows you healthcare anywhere you are in the US.

No doubt New York City believes Medicare Advantage is a less costly form of insurance as compared to Traditional Medicare.

But the Court of Appeals ruling found that the retirees who sued to block the switch to Medicare Advantage were not entitled to their “promissory estoppel” cause of action – the argument that they had been promised traditional Medicare benefits upon retirement over the course of their recruitment and employment with the city.

The ruling deals a blow to the city retirees who have organized to fight the switch – attracting political supporters and elected officials to their cause along the way. A leader in that fight has been the Organization of Public Service Retirees, led by Marianne Pizzitola. In a statement, Pizzitola said the City Council needs to focus on passing legislation that would require retirees be entitled to traditional Medicare benefits. 

“While we are disappointed in the ruling by the Court of Appeals, the solution to protecting seniors’ healthcare has always been with the City Council and the mayor,” Pizzitola said. “The next council and mayor need to do the right thing and codify protections for seniors in city law.”

Spokespeople for Mayor Eric Adams’ office and the city Law Department did not immediately respond to requests for comment on the ruling. 

You have read what has happened in NYC. Labor lost the battle to the city and commercialization and for-profit healthcare. It appears healthcare is moving in such a direction for seniors away from Medicare to commercial Medicare Advantage. You will definitely be coded and hooked up to a plan to feed commercialized healthcare. You will be pretty much locked in and may have issues when you travel. We have had quite a few people write on these issues, Maggie Mahar comes to mind, Dan Crawford, Kip Sullivan, Dale Coberly and Bruce Webb , etc, and myself. I am not sure if it helped.

The overall trend is still for commercialized healthcare even when other models in other countries outperform the US model for far less money. And then we have trump and Republicans getting ready to steal healthcare from those who can not afford it. Read on as The Commonwealth Fund provides the basics.

What is Medicare Advantage?

Medicare Advantage plans are private health insurance plans paid by the federal government to provide Medicare-covered benefits as an alternative to “traditional” or “original” Medicare.

Private plans have been an option in Medicare since the 1970s, but enrollment in private plans remained relatively low through the 1990s. Aside from changing the name of Medicare private plans from Medicare + Choice to Medicare Advantage (also referred to as Medicare Part C), the Medicare Modernization Act of 2003 made significant changes that propelled enrollment growth. More recently, the Affordable Care Act (ACA) made many additional changes that have increased plan enrollment.

Most Medicare Advantage plans are either HMOs, which generally cover only care provided by in-network doctors, hospitals, and other health providers, or by PPOs, which also offer access to out-of-network providers but at a higher cost than in-network providers. PPOs can be local or regional. Local plans serve one or multiple counties, while regional plans serve a single state or group of states (there are 26 regions in all). Regional plans were established in 2003 to increase plan options, especially for beneficiaries in rural areas.

What are the differences between traditional Medicare and Medicare Advantage?

In contrast, Medicare Advantage enrollees can access providers only through more limited provider networks. All Medicare Advantage plans are required to have such networks for doctors, hospitals, and other providers.

Provider participation in these networks can vary greatly. A 2017 analysis found that Medicare Advantage networks included fewer than half (46%) of all Medicare physicians in a given county, on average. The Centers for Medicare and Medicaid Services (CMS), which administers Medicare Advantage plans, has stated that it will strengthen its oversight of plan networks starting in 2024, based in part on an analysis finding that some plans were not in compliance in recent years with “network adequacy” standards.

It’s not clear if broader or narrower networks equate to better or worse care. While many experts note that narrow-network plans can have more control over costs and quality of care, some Medicare Advantage plans tout their broader networks. Unfortunately, access to reliable information on plan networks is typically not easy for enrollees or their family members to obtain. That’s because provider directories are frequently out of date and formatted in ways that make it difficult to directly compare networks. Moreover, prospective enrollees may be less apt to compare networks for postacute care services like home health and skilled nursing care that they might not anticipate needing.

Managed care. Nearly all Medicare Advantage enrollees are required to obtain prior approval, or authorization, for coverage of some treatments or services — something generally not required in traditional Medicare. Plans that require prior authorization can approve or deny care based on medical research and standards of care. For services not subject to prior authorization, plans can deny coverage for care they deem unnecessary after the service is received, as long as they follow Medicare coverage rules and guidelines.

It’s long been a concern that such denials of care via prior authorization, or payment denials after care was delivered, were more widespread than Medicare Advantage plans claimed. A recent government report sheds light on this. It probed coverage denials during one week in June 2019 at 15 Medicare Advantage plans and found that 13 percent of denials were inappropriate and should have been covered under Medicare rules. That extrapolates to some 85,000 denials at those 15 plans for all of 2019. The study also probed payment denials, finding 18 percent were inappropriate and the care should have been paid for. That extrapolates to an estimated 1.5 million wrongful payment denials for all of 2019 at the 15 plans studied. These findings suggest an unacceptably high rate of inappropriate denials of care and payment by some Medicare Advantage plans. Yet, it’s important to balance the findings against the well-established and unacceptable level of inappropriate care delivered by providers in traditional Medicare. Both denials of care and inappropriate, unnecessary care can be harmful as well as costly.

Covered benefits. Medicare Advantage plans must cover all services covered by traditional Medicare under Part A (hospital services, some home health, hospice care, skilled nursing care) and Part B (physician services, durable medical equipment, outpatient drugs, mental health, ambulance services). The vast majority of plans (89% in 2024) also cover Part D prescription drug benefits. Most plans offer additional benefits such as eyeglasses, hearing aids, and some coverage of dental care, such as cleanings.

In 2020, the government began allowing Medicare Advantage plans to include a wide range of telehealth benefits as part of their basic benefit package. Some plans also cover fitness club memberships, caregiver support, meal delivery, or acupuncture.

Traditional Medicare has notable gaps in coverage. For example, it does not cover eyeglasses, hearing aids, basic dental care, or long-term care. It also requires cost sharing for most services. Traditional Medicare also does not have prescription drug coverage, and beneficiaries must choose a separate “stand-alone” Part D plan if they want drug coverage. Part D coverage is offered entirely through private insurance plans; there is no government-run option.

Because of those gaps, many people with traditional Medicare buy Medigap or Medicare Supplemental coverage as well as Part D prescription drug coverage. Medigap plans cover many of the additional costs not covered by traditional Medicare — for instance, the 20 percent copayment for most routine Part B doctor’s services. Some Medigap plans also include services not covered by traditional Medicare, such as access to dental care or eyeglasses.

Medigap coverage is provided through private insurers. The premium that enrollees pay is in addition to the Medicare Part B premium and the Part D premium for those who choose to buy prescription coverage.

In most states, Medigap insurers are required to issue policies to any interested beneficiaries only during certain enrollment windows; at all other times, Medigap insurers can deny coverage or set premiums for policies based on health status (underwrite) of new policyholders. These limited enrollment windows are known as “guaranteed issue” rights. Medigap insurers are prohibited from selling policies to Medicare Advantage enrollees.

Out-of-pocket costs. Like other Medicare beneficiaries, Medicare Advantage enrollees must pay their Part B premium ($174.70 per month in 2024, with higher amounts for higher-income people). A small number of Medicare Advantage plans pay all or a portion of Part B premiums.

As mentioned, Medicare Advantage plans also can charge an additional monthly premium, which typically includes Part D prescription drug benefits. The average premium for a Medicare Advantage plan that includes Part D coverage in 2023 is $15 per month. Some plans cost nothing, while others can be $100 or more. Seventy-three percent of Medicare Advantage enrollees had no premium in 2023; about 7 percent paid $50 or more per month.

Do Medicare Advantage plans cost government and taxpayers less or more?

Traditional Medicare and Medicare Advantage can be compared in many ways, including benefits provided, quality of care, patient outcomes, and costs. Policymakers have focused mainly on comparing costs in traditional Medicare with those in Medicare Advantage, primarily because the original impetus for allowing private insurers to provide Medicare benefits was to reduce costs while maintaining or improving quality of care.

Older and more recent studies alike have largely found that Medicare Advantage plans cost the government and taxpayers more than traditional Medicare on a per beneficiary basis. In 2023, additional cost was about 6 percent, down from a peak of 17 percent in 2009.

Why do Medicare Advantage plans cost more, and how are they paid?

The government pays Medicare Advantage plans a set rate per person, per year (around $12,000 in 2019, not including Part D–related expenses) under what’s known as a risk-based contract. That means that each plan agrees to assume the full risk of providing all care for that inclusive amount. This payment arrangement, called capitation, is also intended to provide plans with flexibility to innovate and improve the delivery of care.

But there are layers of complexity built into and on top of that set rate that allow for various adjustments and bonus payments. While those adjustments have proved useful in some ways, they can also be problematic. They are the main reason why Medicare Advantage costs the government more than traditional Medicare for covering the same beneficiary.

Medicare Advantage payments are based on a system of benchmarks, bids, and quality incentives.

Benchmarks. Plan benchmarks are the maximum amount the federal government will pay a Medicare Advantage plan. Benchmarks are set in statute as a percentage of traditional Medicare spending in a given county, ranging from 115 percent to 95 percent. For counties with relatively low spending, benchmarks are set higher than average spending for traditional Medicare (for example, 115%); for counties with relatively high spending, benchmarks are set lower than average traditional Medicare spending (for example, 95%). Special Needs Plans and other Medicare Advantage plans are paid in the same manner, with the same benchmarks.

Rebates. If a plan’s bid is below the local benchmark — as is the case for the majority of plans — then the plan keeps part of the difference between the bid and benchmark. This amount, called the rebate, is equivalent to a shared savings between the federal government and plans. Plans are required to use the rebate to lower patient cost sharing, lower premiums, or provide some coverage for benefits not included in traditional Medicare. Rebate dollars also can be used to pay for administrative expenses and profits associated with providing additional benefits.

If a plan’s bid exceeds the benchmark, the plan can charge a premium for coverage of Part A and Part B benefits, in addition to premiums for supplemental benefits and Part D coverage. Plans that receive rebates can also charge premiums for supplemental benefits and Part D coverage.

Quality adjustments. Quality ratings affect benchmarks as well as rebate size.

  • Benchmarks are raised by 5 percent for plans with four or more stars and, in certain counties, are increased by 10 percent for plans with high ratings. However, the ACA required that benchmarks (including quality bonuses) cannot be higher than they would have been prior to the ACA. This can constrain the quality bonus percentages and result in lower adjustments.
  • For the rebate, plans with three stars or fewer receive 50 percent of the difference between the bid and the benchmark; plans with three-and-a-half or four stars receive 65 percent of the difference; and plans with four-and-a-half or five stars receive 70 percent of the difference.

Risk adjustment. Both the rebate and the bid amount are “risk adjusted” to account for enrollees’ health status. Without risk adjustment, Medicare Advantage plans would have an incentive to select the healthiest, lowest-cost beneficiaries and avoid enrolling the sickest, highest-cost beneficiaries.

Payment is affected by each beneficiary’s risk score, which represents the expected cost of each enrollee relative to the cost of the average Medicare beneficiary. Thus, the average enrollee has a risk score of 1.0. An older person with multiple chronic conditions would have a risk score above 1.0, whereas a younger person with no health issues would have a risk score below 1.0.

The prevalence of many chronic conditions is similar for enrollees in traditional Medicare and Medicare Advantage, after separating out Special Needs Plans.

In addition to more complete coding, patients may be coded for conditions that have no bearing on their health expenditures. Critics have also asserted that many Medicare Advantage plans have been “upcoding”— that is, systematically assessing enrollees as having more health conditions and being sicker on average than is actually the case. This inappropriately raises total payments to plans. Medicare Advantage insurers counter that their coding is more accurate and complete.

In response to the upcoding debate, Congress required CMS to adjust risk scores down 3.4 percent beginning in 2010 and 5.9 percent in 2018 and future years. The CMS administrator has the authority to increase the adjustment, but no administrator has chosen to do so.

Medical loss ratios. Since 2014, Medicare Advantage and Part D prescription drug plans have been required to have a medical loss ratio of no lower than 85 percent. This means that plans’ administrative expenses and profits, or margins, can be no higher than 15 percent of the total revenues plans receive from the federal government (in the form of payments) and enrollees (in the form of premiums). The minimum medical loss ratio requirement was intended to create incentives for plan sponsors to limit administrative costs and profits.

Plans that do not meet this requirement must remit payments to CMS. If this requirement is not met for three consecutive years, the plan may not be permitted to enroll new beneficiaries. If it is not met for five consecutive years, the plan may be terminated.

Margins are higher for dual-eligible and chronic-condition Special Needs Plans than for other plans. Margins have historically also been higher for institutional Special Needs Plans, though they were lower in 2020, likely because of COVID-19.

Margins for dual-eligible and chronic-condition Special Needs Plans are higher compared to other Medicare Advantage plans.

How much choice and competition is there between Medicare Advantage plans and traditional Medicare?


In about 60 percent of U.S. counties, beneficiaries have a choice of 20 or more Medicare Advantage plans.

Switching between Medicare Advantage and traditional Medicare remains uncommon. A 2016 analysis found that from 2007 to 2014, only between 9 percent and 11 percent of Medicare Advantage enrollees voluntarily switched plans each year. And only 2 percent of Medicare Advantage plan enrollees each year switched to traditional Medicare.

What does the future look like for Medicare Advantage?

Medicare Advantage plans are an integral part of the Medicare program. They provide beneficiaries a multitude of options and offer additional benefits to enrollees. As the popularity of these plans continues to grow and enrollment rises, however, the Medicare program will face several challenges. First, higher costs relative to traditional Medicare will strain federal spending and the solvency of the Hospital Insurance (Part A) trust fund. Second, increased enrollment could necessitate changes to the payment system for Medicare Advantage plans. Third, questions remain about the quality of Medicare Advantage plans relative to traditional Medicare.

With Medicare Advantage plans predicted to soon become the dominant form of Medicare coverage, it will be important to assess beneficiaries’ experiences and the long-term sustainability of the program to ensure Medicare Advantage plans provide effective, efficient, and equitable care.
