Medicare Advantage Insurers Are Dropping Plans, Leaving Seniors Scrambling for New Coverage

The promise of stability in Medicare Advantage is fraying as major insurers announce exits from key markets, forcing tens of thousands of seniors to navigate a complex new enrollment period.

SHORT ANSWER
Major insurers are exiting Medicare Advantage markets for 2027, disrupting coverage for thousands of seniors and challenging the perceived stability of these plans.

The direct answer

The conventional wisdom is that Medicare Advantage plans offer predictable coverage. However, this narrative is being challenged as insurers like Humana are strategically withdrawing from certain markets for the 2027 plan year, impacting tens of thousands of seniors

"Humana plans to shut down more Medicare Advantage plans next year as the insurer works to improve profits, auguring more disruption for seniors in the privatized Medicare program."

. This move, driven by a desire to improve profitability, means beneficiaries must find new plans, potentially outside their preferred networks or even their current counties. The Centers for Medicare & Medicaid Services (CMS) has finalized policies for 2027, projecting a net average increase of 2.48% in Medicare Advantage payments, which some analysts believe is above expectations for insurers like UnitedHealth and Humana [c1, c3, c6]. Despite this, the strategic exits indicate that not all plans are viewed as sustainable by the companies themselves. This situation creates an urgent need for beneficiaries to understand their options, as missing enrollment windows can lead to medically underwritten Medigap policies, potentially increasing costs or denying coverage altogether

"Members whose plan exits have a 63-day guaranteed-issue Medigap window; miss it and insurers can medically underwrite, charge more, or deny coverage."

.

The Profit-Driven Exit Strategy

Humana's decision to shut down more Medicare Advantage plans for 2027 is a clear signal that profitability is a primary driver for insurers in this market

"Humana plans to shut down more Medicare Advantage plans next year as the insurer works to improve profits, auguring more disruption for seniors in the privatized Medicare program."

. While CMS has finalized 2027 payment policies, projecting a net average increase of 2.48% for MA plans

"The policies in this Rate Announcement are projected to result in a net average increase of 2.48%, or over $13 billion in additional MA payments to plans in CY 2027."

, this doesn't guarantee universal plan availability. Insurers are strategically exiting markets or specific plans where they anticipate lower returns or higher costs. This suggests that the financial health of the plan, from the insurer's perspective, dictates its continued existence, not necessarily the continuity of care for its members. The market is being 'redrawn' by these companies, often with little notice to those affected

"Members whose plan exits have a 63-day guaranteed-issue Medigap window; miss it and insurers can medically underwrite, charge more, or deny coverage."

. This is a stark contrast to the idea that Medicare Advantage offers a stable, unchanging healthcare pathway.

Navigating the Medigap Minefield

The most immediate concern for seniors losing their Medicare Advantage plans is the potential impact on their ability to secure supplemental coverage. For those whose plans are exiting, there's typically a 63-day guaranteed-issue window for Medigap policies

"Members whose plan exits have a 63-day guaranteed-issue Medigap window; miss it and insurers can medically underwrite, charge more, or deny coverage."

. However, missing this window is critical. After it closes, insurers can medically underwrite applicants, meaning they can charge higher premiums or deny coverage altogether based on pre-existing health conditions. This creates a high-stakes enrollment period for affected seniors. They must not only find a new Medicare Advantage plan but also ensure they secure Medigap coverage if they need it, all within strict, time-sensitive deadlines. The disruption isn't just about changing doctors; it's about potentially losing access to affordable, comprehensive coverage.

CMS's Balancing Act

The Centers for Medicare & Medicaid Services (CMS) is attempting to balance the need for private insurer participation with the protection of beneficiaries. Their finalized policies for 2027 aim to improve 'payment accuracy and competition' while advancing a 'sustainable and stable MA program' [c1, c2]. The projected 2.48% increase in payments is seen by some as positive for insurers like UnitedHealth and Humana, potentially boosting their stock prices [c3, c4]. However, the CMS's definition of sustainability seems to align with insurer profitability rather than guaranteed member continuity. While CMS emphasizes accountability and long-term sustainability

, the reality on the ground for seniors facing plan exits suggests that 'sustainability' is a flexible term, easily adjusted when profit margins are threatened.

Common mistakes

PALMELLE'S VIEW
In our view, the current wave of Medicare Advantage plan exits underscores a fundamental tension between the profit motives of private insurers and the healthcare security needs of seniors. While CMS aims for a 'sustainable' program with adjusted payments [c1, c2], this sustainability appears to be defined by profitability for the payers, not necessarily by consistent, long-term coverage for beneficiaries. The promise of 'stability' in Medicare Advantage is proving to be a mirage for many, as insurers can and do redraw the map of coverage based on market conditions, leaving seniors scrambling. This isn't just an inconvenience; for those who miss enrollment windows, it can mean facing higher premiums or outright denial of supplemental coverage like Medigap due to pre-existing conditions

"Members whose plan exits have a 63-day guaranteed-issue Medigap window; miss it and insurers can medically underwrite, charge more, or deny coverage."

BOTTOM LINE
If you receive a notice that your Medicare Advantage plan is exiting your area, immediately consult Medicare.gov or call 1-800-MEDICARE to understand your Special Enrollment Period deadlines for switching plans and securing Medigap coverage.
WHEN THIS CHANGES
Your coverage options and costs can change significantly if your current Medicare Advantage plan is discontinued or if you miss a critical enrollment deadline. Specifically, if you lose coverage due to an insurer exiting the market and fail to enroll in a new plan or secure a Medigap policy within your guaranteed-issue window, you could face higher out-of-pocket costs or denial of coverage for pre-existing conditions.

Frequently asked

What happens if my Medicare Advantage plan is discontinued?

If your plan is leaving your area, you'll likely receive a notice from your insurer. You'll have a Special Enrollment Period (SEP) to switch to another Medicare Advantage plan or back to Original Medicare with a Part D plan. You also typically have a 63-day guaranteed-issue period for Medigap policies after your current plan ends, which is crucial for securing supplemental coverage without medical underwriting.

How can I find out if my plan is changing for 2027?

Insurers are required to send out Annual Election Period (AEP) notices, including plan changes or discontinuation, by September 30th each year for the following year. You should receive a "Plan" or "Annual Notice of Changes" (ANOC) letter from your current Medicare Advantage provider detailing any modifications or exits for 2027.

Is it better to stay with Original Medicare and get a Medigap plan?

Original Medicare with a Medigap plan offers more predictable costs and freedom to see any doctor who accepts Medicare. However, Medigap premiums can be higher than Medicare Advantage, and you'll need a separate Part D plan for prescription drugs. Medicare Advantage plans often have lower monthly premiums and may include extra benefits, but network restrictions and potential plan changes can be drawbacks.
