Understanding the 2024 Open Enrollment

Everything You Need to Know

In this article, we'll delve into the intricacies of Medicare Open Enrollment, explore available Medicare plans for retirees, and compare two prominent insurance providers, MetLife and Aetna, to help you make informed decisions about your healthcare coverage.

What is Medicare Open Enrollment?

Medicare Open Enrollment, also known as the Annual Election Period (AEP), is a designated time each year when Medicare beneficiaries can make changes to their healthcare coverage. During this period, individuals who are already enrolled in Medicare can review their current plans, explore new options and make adjustments to better suit their evolving healthcare needs. This review and any subsequent changes can be done through the Medicare website.

When Does Medicare Open Enrollment Occur?

Medicare Open Enrollment typically occurs annually from October 15th to December 7th. It's crucial to mark these dates on your calendar, as this is the time when you can make important decisions about your Medicare coverage for the upcoming year. Any changes you make during this period will take effect on January 1, 2024.

What Can You Do During Medicare Open Enrollment?

Medicare Open Enrollment offers several opportunities for beneficiaries to make changes to their healthcare coverage. Here are some of the key actions you can take.

1. Switch Medicare Advantage Plans: If you're enrolled in a Medicare Advantage plan (Part C), you can switch to a different Medicare Advantage plan that better suits your needs.

2. Switch Prescription Drug Plans: Medicare Part D covers prescription drugs. During Open Enrollment, you can change your Part D plan to one that covers the medications you need at a lower cost.

3. Return to Original Medicare: If you're currently in a Medicare Advantage plan but want to return to Original Medicare (Part A and Part B), you can do so during this period. You can also enroll in a standalone Part D plan if you choose.

4. Enroll in a Medicare Supplement (Medigap) Plan: If you have Original Medicare and want to enhance your coverage, you can enroll in a Medicare Supplement plan. Medigap plans help cover out-of-pocket costs, such as deductibles and co-pays.

5. Make Changes to Your Medicare Advantage Plan: If you're already in a Medicare Advantage plan, you can switch to a different plan offered by the same insurance company, make changes to your coverage options or return to Original Medicare.

Medicare Plans Available for Retirees

When it comes to selecting a Medicare plan, retirees have several options to consider. To see if you qualify or to sign up, visit the Medicare website. Here are the main types of Medicare coverage.

Original Medicare (Part A and Part B): Original Medicare is the traditional fee-for-service program offered by the federal government. Part A covers hospital services, while Part B covers medical services. Beneficiaries can choose any healthcare provider that accepts Medicare.

Medicare Advantage (Part C): Medicare Advantage plans are offered by private insurance companies and provide an alternative to Original Medicare. These plans often include additional benefits like prescription drug coverage, dental, vision and wellness programs.

Medicare Part D: Part D plans are stand-alone prescription drug plans (PDPs) offered by private insurers. They help cover the cost of prescription medications.

Medicare Supplement (Medigap) Plans: Medigap plans are also provided by private insurance companies. They work alongside Original Medicare and help pay for out-of-pocket costs, such as deductibles, co-pays and coinsurance.

The Marketplace

While Medicare primarily serves retirees aged 65 and older, the Health Insurance Marketplace, often referred to as the "Obamacare Marketplace," is another avenue for individuals under 65 to obtain health insurance coverage. It's essential to differentiate between Medicare and the Marketplace, as they serve distinct populations.

The Marketplace offers private health insurance plans to individuals and families who do not qualify for Medicare or Medicaid. These plans can be a valuable option for people who are not yet eligible for Medicare and do not have employer-sponsored coverage. To explore Marketplace plans, individuals can visit or their state's equivalent website during the annual Open Enrollment Period, typically running from November 1st to December 15th.

Comparing MetLife vs. Aetna

MetLife and Aetna are two well-known insurance providers that offer a range of insurance products, including Medicare plans. Let's briefly compare these two companies.


  • MetLife is a global insurance company with a long history of providing various insurance and financial products.
  • MetLife offers Medicare Advantage (Part C) plans that often include dental, vision and prescription drug coverage.
  • The availability of MetLife Medicare plans can vary by location, so it's essential to check what's offered in your area.


  • Aetna is a subsidiary of CVS Health and is recognized for its broad network of healthcare providers.
  • Provides Medicare Advantage plans and Medicare Part D prescription drug plans.
  • Offers a wide selection of plans, which can provide flexibility in finding one that suits your specific needs.

Final Notes
