Your Former Employer May Be Steering You Away From Traditional Medicare

Automatic enrollment in Medicare Advantage plans is shrinking retiree choice, often without clear consent.

SHORT ANSWER
Employers are increasingly auto-enrolling retirees into Medicare Advantage plans, limiting their choices and potentially pushing them away from traditional Medicare.

The direct answer

Many retirees believe they have a free choice of Medicare plans, but a growing trend of employers automatically enrolling former employees into Medicare Advantage (MA) plans is challenging this assumption

"When an employer or union contracts for a Medicare Advantage plan for its retirees, Medicare allows them to enroll the retirees automatically. In 2021, the Center for Medicare Advocacy wrote about the increasing automatic enrollment of retired Medicare beneficiaries into Medicare Advantage plans by their former employers or unions in place of traditional (or original) Medicare."

. This practice, often presented as a benefit, can limit access to preferred doctors and specialists available in traditional Medicare

"MA plans use supplemental benefits and reduced premiums and cost-sharing – subsidized by rebates – to entice people to enroll in MA plans, while downplaying some of the drawbacks in MA enrollment, including excessive use of prior authorization and provider network restrictions."

. In some cases, employers offer MA plans as the *only* option, forcing retirees to either accept the MA plan or forfeit employer subsidies that help cover premiums, including those for Medigap policies that complement traditional Medicare

"Just over half of large employers that offer Medicare Advantage have used it to replace regular Medicare instead of offering their employees a choice. This means that to remain in traditional Medicare, retirees would have to give up an employer subsidy that covers all or part of the Medicare Advantage premium and pay the full Medigap premium."

. This shift is not always transparent, and the nuances of MA plans, such as annual benefit changes and restrictive provider networks, can catch seniors off guard

"The important takeaway is this: don't assume your Medicare plan will stay the same every year. Benefits, provider networks, drug formularies, and out-of-pocket costs can all change annually. That's why reviewing your coverage during Open Enrollment is becoming more important than ever."

. The Center for Medicare Advocacy has noted this increasing trend, raising alarms about the erosion of beneficiary choice and potential negative impacts on healthcare access

"When an employer or union contracts for a Medicare Advantage plan for its retirees, Medicare allows them to enroll the retirees automatically. In 2021, the Center for Medicare Advocacy wrote about the increasing automatic enrollment of retired Medicare beneficiaries into Medicare Advantage plans by their former employers or unions in place of traditional (or original) Medicare."

The Illusion of Choice

The conventional wisdom suggests Medicare beneficiaries enjoy a wide array of choices, particularly when transitioning from employer coverage. However, the reality for many retirees is far less liberating. Employers are increasingly opting to offer Medicare Advantage (MA) plans to their former employees, and a significant portion of these plans are automatically enrolling retirees

"When an employer or union contracts for a Medicare Advantage plan for its retirees, Medicare allows them to enroll the retirees automatically. In 2021, the Center for Medicare Advocacy wrote about the increasing automatic enrollment of retired Medicare beneficiaries into Medicare Advantage plans by their former employers or unions in place of traditional (or original) Medicare."

. This means that instead of presenting a menu of options, employers are presenting a fait accompli. Just over half of large employers offering MA have replaced traditional Medicare entirely, leaving retirees with a stark choice: accept the MA plan or potentially pay more out-of-pocket for traditional Medicare and supplemental coverage

"Just over half of large employers that offer Medicare Advantage have used it to replace regular Medicare instead of offering their employees a choice. This means that to remain in traditional Medicare, retirees would have to give up an employer subsidy that covers all or part of the Medicare Advantage premium and pay the full Medigap premium."

. This isn't about expanding choice; it's about consolidating it, often in ways that benefit the employer's bottom line more than the retiree's health.

The Subsidized Squeeze

Medicare Advantage plans are often sweetened with employer subsidies, making them appear financially attractive. However, these subsidies can become a trap. If a retiree wishes to remain in traditional Medicare, they may have to forgo these employer contributions, which could cover all or part of the MA premium. This forces them to then pay the full cost of a Medigap policy, which can be considerably more expensive than the subsidized MA premium

"Just over half of large employers that offer Medicare Advantage have used it to replace regular Medicare instead of offering their employees a choice. This means that to remain in traditional Medicare, retirees would have to give up an employer subsidy that covers all or part of the Medicare Advantage premium and pay the full Medigap premium."

. The Center for Retirement Research highlights that in about 65% of cases where employers offer MA, it's the retirees' only option

"The employers and unions that still offer health benefits to retirees are increasingly rolling out Medicare Advantage plans to at least some of their retirees. And in about 65 percent of these cases, an Advantage plan was the retirees' only option last year, up sharply from 44 percent in 2022, according to KFF, a healthcare research organization."

. This lack of alternatives, combined with the financial incentive to accept the MA plan, creates a powerful push away from traditional Medicare, even if the retiree would prefer it.

Hidden Drawbacks of MA

While MA plans can offer attractive benefits like reduced premiums and supplemental coverage, they come with significant trade-offs that retirees might not fully grasp during automatic enrollment. These plans often employ prior authorization, a process that can delay or deny care, and restrict provider networks

"MA plans use supplemental benefits and reduced premiums and cost-sharing – subsidized by rebates – to entice people to enroll in MA plans, while downplaying some of the drawbacks in MA enrollment, including excessive use of prior authorization and provider network restrictions."

. Furthermore, benefits, drug formularies, and out-of-pocket costs can change annually, making long-term planning difficult

"The important takeaway is this: don't assume your Medicare plan will stay the same every year. Benefits, provider networks, drug formularies, and out-of-pocket costs can all change annually. That's why reviewing your coverage during Open Enrollment is becoming more important than ever."

. This constant flux means that a plan that seems advantageous one year might become a significant burden the next, a reality that automatic enrollment doesn't prepare beneficiaries for. The Center for Medicare Advocacy has raised concerns that this trend could lead to a decline in access to necessary care for vulnerable populations

"When an employer or union contracts for a Medicare Advantage plan for its retirees, Medicare allows them to enroll the retirees automatically. In 2021, the Center for Medicare Advocacy wrote about the increasing automatic enrollment of retired Medicare beneficiaries into Medicare Advantage plans by their former employers or unions in place of traditional (or original) Medicare."

Common mistakes

PALMELLE'S VIEW
In our view, the notion that retirees have unfettered choice in Medicare coverage is becoming a charming relic of the past. The increasing prevalence of automatic enrollment into Medicare Advantage plans by former employers is a calculated maneuver that prioritizes cost-shifting for employers over genuine beneficiary autonomy

"Just over half of large employers that offer Medicare Advantage have used it to replace regular Medicare instead of offering their employees a choice. This means that to remain in traditional Medicare, retirees would have to give up an employer subsidy that covers all or part of the Medicare Advantage premium and pay the full Medigap premium."

. While MA plans might tout lower premiums, this often comes at the cost of restricted provider networks and increased administrative hurdles like prior authorization, a process the industry euphemistically calls 'utilization management'

"MA plans use supplemental benefits and reduced premiums and cost-sharing – subsidized by rebates – to entice people to enroll in MA plans, while downplaying some of the drawbacks in MA enrollment, including excessive use of prior authorization and provider network restrictions."

. Retirees are being nudged, or rather herded, into plans that may not align with their long-term healthcare needs or preferences, all under the guise of a 'simplified' benefit package

"The employers and unions that still offer health benefits to retirees are increasingly rolling out Medicare Advantage plans to at least some of their retirees. And in about 65 percent of these cases, an Advantage plan was the retirees' only option last year, up sharply from 44 percent in 2022, according to KFF, a healthcare research organization."

BOTTOM LINE
Contact your former employer's benefits administrator immediately to confirm your current Medicare coverage status and understand your options for opting out of Medicare Advantage if you prefer traditional Medicare.
WHEN THIS CHANGES
Your automatic enrollment situation can change during Medicare's Annual Election Period (October 15 to December 7) each year. During this time, you can switch from Medicare Advantage back to traditional Medicare, or vice versa, and change your Medicare Part D prescription drug plan. Employer-specific enrollment periods or qualifying life events, such as moving, may also trigger changes.

Frequently asked

Can my employer really enroll me automatically in Medicare Advantage?

Yes, Medicare allows employers or unions to automatically enroll their retirees into a contracted Medicare Advantage plan. However, this doesn't mean you have to stay in it if it's not right for you. You generally have the right to opt-out and return to traditional Medicare, though this may affect employer subsidies.

What's the difference between traditional Medicare and Medicare Advantage?

Traditional Medicare (Parts A and B) covers most medically necessary services and is accepted by most doctors nationwide. Medicare Advantage (Part C) is an all-in-one plan offered by private companies approved by Medicare, often including prescription drug coverage and additional benefits, but with specific provider networks and rules.

How can I avoid being automatically enrolled or switch out of an MA plan?

Review all communications from your former employer carefully. If you are automatically enrolled and wish to opt-out, contact your employer's benefits administrator or the MA plan directly during your initial enrollment period or the annual Open Enrollment (Oct 15 - Dec 7) to switch back to traditional Medicare.
