You can also choose a Medicare Advantage (Part C) plan that bundles all your coverage into one plan.

Original Medicare

Original Medicare is provided through the federal government and is made up of Part A and Part B. It provides coverage for all your basic healthcare needs.

Original Medicare does not cover everything, including prescription drugs. You can purchase a prescription drug (Part D) plan as an add-on.

Medicare Advantage in Tennessee

If you’d like more coverage or to bundle all your coverage into one plan, you may decide to purchase a Medicare Advantage (Part C) plan instead. These are insurance plans you buy from private health insurance carriers.

Part C plans provide all the basic coverage offered by Original Medicare in Tennessee. They may also provide drug coverage. Some plans offer more extensive coverage, including services such as:

  • hearing tests
  • dental care
  • wellness programs

Each of these carriers offers several plans with varying premiums and coverage options that work with a different network of doctors and pharmacies. Be sure to check what healthcare facilities and providers are part of the network before enrolling in a plan.

When searching for plans, use your ZIP code to make sure the plans you’re comparing are all available in your county.

When can I enroll in Medicare Tennessee plans?

There are two annual enrollment periods for Medicare plans in Tennessee: general enrollment and open enrollment.

The Medicare general enrollment period is from January 1 through March 31. The Medicare open enrollment period stretches from October 15 through December 7. During both, you can enroll in Original Medicare in Tennessee, add drug coverage, or even switch to an Advantage plan.

Around your 65th birthday, you’ll become eligible and can enroll in Medicare Tennessee. This initial enrollment period starts the 3 months before your birth month, continues during your birth month, and ends 3 months after, giving you 7 months to research coverage options and find a plan that matches your needs.

If you choose not to access Medicare when you turn 65 because you still have employer insurance, you will qualify for a special enrollment period. This period will begin when you lose employer coverage.

You’ll also qualify for special enrollment for several other qualifying life changes.

If you do not qualify for special enrollment and do not sign up during your initial enrollment period, you may have to pay a late enrollment penalty.

Tips for enrolling in Medicare in Tennessee

With so many options, finding the right plan can take time and research. When choosing from among Original Medicare or Medicare Advantage, and considering add-ons like Medigap plans, think about each of the following:

  • Coverage needs: When comparing plans, stay focused on your coverage needs. Make a list of all the health services you access, such as home healthcare, doctor’s visits, hospital care, or hearing screenings. Then, list additional services you’d like, such as dental coverage or transportation assistance. Look for plans that match your healthcare needs and provide adequate coverage.
  • Preferred physician: Are you happy with the care provided by your preferred physician? Medicare Advantage plans in Tennessee work only with network-approved doctors, so call your physician to find out which insurance carriers they accept.
  • Medications: One of the biggest out-of-pocket expenses you have is for prescription medications. If you plan to enroll in Original Medicare, adding Part D could help reduce some of your medication costs. If you plan to enroll in an Advantage plan, read about the drug coverage offered and make sure your prescriptions will be covered.
  • Star rating: If you haven’t been able to narrow down your search based on the considerations above, you can consult the CMS star ratings. This system ranks Medicare plans on a scale from 1 to 5. Plans that score a 4 or 5 provide quality care and excellent support to insured members.
