Medicare's annual Open Enrollment Period begins October 15, giving Middle Tennessee residents an opportunity to review their health and prescription drug coverage before 2027.

The enrollment window runs through December 7, 2026, and changes generally take effect January 1.

For retirees in Nashville, Franklin, Murfreesboro, Hendersonville, and surrounding communities, a little preparation now could prevent costly surprises next year.

Start with the letter from your current plan.

Medicare Advantage and prescription drug plans send an Annual Notice of Change each fall explaining changes scheduled for the coming year.

That notice may describe different premiums, deductibles, copayments, drug coverage, and provider networks.

Even if you like your current plan, do not assume every benefit will remain the same.

If you have not received the notice, contact your plan and request it.

Check your doctors and hospitals.

People enrolled in Medicare Advantage should confirm that their primary-care doctor, specialists, hospitals, and preferred clinics will be in-network in 2027.

A provider who participates this year may not necessarily participate next year.

Ask the provider's office as well as the insurance plan, because directories can be outdated.

Review every prescription.

Write down your medications, dosages, and preferred pharmacies before comparing plans.

Drug plans can change their formularies, coverage restrictions, pharmacy arrangements, and out-of-pocket costs.

Compare the total estimated annual cost of coverage, not just the advertised monthly premium.

Someone taking several medications may find that a seemingly inexpensive plan costs much more over a full year.

Understand what can change during this enrollment period.

Eligible beneficiaries can switch Medicare Advantage plans, move between Medicare Advantage and Original Medicare, or join, drop, or change a stand-alone Medicare prescription drug plan under applicable rules.

Original Medicare and Medicare Advantage are different ways to receive Medicare coverage, and the right choice depends on individual care needs and finances.

One particularly important caution concerns Medigap, also called Medicare Supplement Insurance.

Switching from Medicare Advantage back to Original Medicare does not always guarantee that you can purchase a Medigap policy without medical underwriting.

Before making that change, confirm your eligibility, potential premiums, and any special protections that may apply.

Get free assistance close to home.

Tennessee's State Health Insurance Assistance Program, known as TN SHIP, provides free, unbiased Medicare counseling to eligible residents, families, and caregivers.

Counselors can help explain options and compare coverage without representing a particular insurance company.

Call TN SHIP at 1-877-801-0044 to ask about assistance, including opportunities in Middle Tennessee.

Medicare also offers plan comparisons and help by telephone at 1-800-MEDICARE.

Have your Medicare information, medication list, and current coverage details available when requesting a comparison, but protect personal identifiers from unsolicited callers.

Watch out for pressure and scams.

Open Enrollment can bring more advertising, phone calls, and sales pitches promising special benefits or lower costs.

Do not make a decision based on a single advertisement or an unsolicited call.

Verify the plan's benefits and network details independently, and never share your Medicare number with someone whose identity you have not confirmed.

Remember that Open Enrollment is not a requirement to change plans.

If your existing coverage will still meet your needs in 2027, you may be able to keep it without taking action.

However, checking the changes is still worthwhile, especially if your medications, doctors, budget, or health needs have changed.

The practical goal is simple: know what you have, understand what will change, and decide before December 7.

A careful review this fall can help make January a little less stressful.
