Millions of Medicare beneficiaries received an unpleasant surprise heading into 2026. Approximately 2.9 million Medicare Advantage enrollees were forced to find new coverage after insurers exited markets or discontinued plans. On top of that, nearly 10% of Medicare Advantage members were affected by plan terminations this year, with rural residents experiencing some of the highest disruption rates. If you’ve received notice that your plan is ending, acting quickly can help you avoid coverage gaps, unexpected costs, and disruptions to your healthcare. Here are seven moves you can make before your coverage lapses.

1. Read Every Notice From Your Insurance Company

Many seniors set aside plan notices, assuming they contain routine updates. However, if your Medicare Advantage plan is ending, your insurer is required to send important information explaining what is happening and when coverage will end. These notices often outline whether you’ll be automatically enrolled in another plan or need to choose coverage yourself. Missing key deadlines could leave you scrambling to make decisions under pressure. Taking time to carefully review every document is the first step in protecting your Medicare Advantage coverage options.

2. Verify Exactly When Your Current Coverage Ends

One of the biggest mistakes beneficiaries make is assuming they have more time than they actually do. Plan termination dates can vary depending on the insurer and the circumstances surrounding the discontinuation. Knowing your exact coverage end date allows you to plan appointments, refill prescriptions, and complete paperwork before disruptions occur. The last thing you want is to discover your coverage has ended while standing at a pharmacy counter or doctor’s office. Mark important dates on your calendar and keep copies of all correspondence related to your Medicare Advantage coverage.

3. Compare Available Medicare Advantage Plans Immediately

Analysis from KFF found that nearly 99% of beneficiaries whose plans terminated had at least one Medicare Advantage Prescription Drug plan available in their area for 2026. However, available plans may have different provider networks, drug formularies, premiums, and out-of-pocket costs than your previous coverage. Comparing plans carefully can help ensure your doctors and medications remain covered. Even if your current insurer offers a replacement plan, it is worth evaluating all available options before enrolling.

4. Check Whether Your Doctors Are Still In-Network

Many seniors focus on premiums and benefits while overlooking provider networks. Unfortunately, networks can vary significantly between Medicare Advantage plans, even when offered by the same insurance company. That said, changing plans can require beneficiaries to switch providers if their preferred physicians are not included in the new network. Before selecting a new plan, contact your doctors directly and verify participation. Doing this upfront can prevent frustrating surprises after enrollment.

5. Review Prescription Drug Coverage Carefully

Prescription coverage differences can have a major impact on your healthcare costs. A medication covered under your previous plan may move to a different pricing tier or require prior authorization under a new plan. Even though Medicare Part D out-of-pocket costs remain capped at $2,100 in 2026, drug coverage details still matter. Make a list of every medication you take and compare formularies before making a final decision. Spending a few extra minutes researching can save hundreds or even thousands of dollars throughout the year.

6. Consider Whether Original Medicare Makes Sense

Losing a Medicare Advantage plan can also create an opportunity to reevaluate your healthcare strategy. Some beneficiaries choose to return to Original Medicare and pair it with a Part D prescription drug plan. Those who lose Medicare Advantage coverage due to plan termination may qualify for guaranteed-issue rights that allow them to purchase certain Medigap policies without medical underwriting. This protection can be particularly valuable because Medigap insurers can often deny coverage or charge higher premiums outside special enrollment situations. Reviewing both Medicare Advantage and Original Medicare options can help ensure you’re choosing coverage that matches your healthcare needs.

7. Get Free Help Before Making a Final Decision

Medicare decisions can feel overwhelming, especially when you’re dealing with unexpected plan changes. Fortunately, every state offers free assistance through State Health Insurance Assistance Programs (SHIPs), which provide unbiased Medicare counseling. These counselors can explain enrollment periods, compare plans, and help you understand costs without earning commissions. This is particularly important because some industry experts have raised concerns about incentives that may influence certain sales recommendations. Taking advantage of free expert guidance can help you make a more confident decision.

Protecting Your Healthcare Before the Clock Runs Out

The loss of Medicare Advantage plans has created challenges for millions of seniors, but it does not have to result in a coverage crisis. Most beneficiaries still have multiple Medicare Advantage options available, while others may find that Original Medicare better fits their needs. But you need to act early. Don’t wait until deadlines are approaching. Reviewing networks, prescriptions, enrollment dates, and alternative coverage options now can prevent costly mistakes later.
