Medicare in Tennessee: compare your plan options with a licensed agent

Your guide to Medicare in Tennessee

Last reviewed October 2026 by the licensed team at Amerance Health Insurance Group. Costs shown are 2026 Medicare figures from CMS.

Medicare is a federal program, so Parts A and B work the same way in Tennessee as in every other state. What changes from state to state is which private plans you can choose from, the state rules that apply to Medicare Supplement insurance, and the local programs that can help you pay for coverage. This page covers what's specific to Tennessee.

Your Medicare options in Tennessee

People with Medicare in Tennessee choose between two main paths:

Original Medicare, with a Medicare Supplement and Part D

Original Medicare (Part A for hospital care and Part B for medical care) lets you see any doctor or hospital in the U.S. that accepts Medicare. That's useful if you see specialists across Tennessee or spend part of the year out of state. Because Original Medicare has no yearly out-of-pocket limit, many people add a Medicare Supplement (Medigap) policy to cover deductibles and coinsurance, plus a stand-alone Part D plan for prescriptions.

Medicare Advantage (Part C)

Medicare Advantage plans are offered by private insurance companies approved by Medicare. They bundle hospital, medical and usually drug coverage into one plan, often with dental, vision and hearing benefits and a yearly out-of-pocket maximum. Plans are approved county by county, so what's available in Nashville may differ from what's available in Memphis or rural Tennessee. Most use provider networks (HMO or PPO), so it's important to confirm your doctors and hospitals before you enroll.

Tennessee Medicare Supplement (Medigap) rules

Tennessee doesn't have a birthday rule, but it gives people under 65 and people leaving TennCare more Medigap protections than federal law requires.

• No birthday rule: outside open enrollment and guaranteed issue situations, insurers can ask health questions when you switch plans.
• Under 65: since 2011, insurers that sell Medigap to people 65 and older must also offer the same plans to people under 65 with Medicare due to a disability or ESRD, with a 6-month open enrollment period. Premiums for under-65 enrollees can be higher.
• Leaving TennCare: people 65 and older who are disenrolled from TennCare have a 63-day guaranteed issue period to buy a Medigap policy.

Everywhere in the U.S., your strongest protection is your Medigap Open Enrollment Period: the 6 months starting when you're 65 or older and enrolled in Part B. During that window, insurers in Tennessee must sell you any Medigap plan they offer, at the same price as someone in good health. Plan G and Plan N are common choices for people new to Medicare. Compare what each Medigap plan covers.

Turning 65 in Tennessee

Your Initial Enrollment Period is the 7 months around your 65th birthday: the 3 months before your birthday month, the month itself and the 3 months after. Sign up in the 3 months before your birthday month so your coverage starts on the first day of the month you turn 65. If you already receive Social Security, you'll be enrolled in Parts A and B automatically. Otherwise, apply through Social Security online, by phone at 1-800-772-1213, or at a local Social Security office in Tennessee.

If you're still working, you may be able to delay Part B without a penalty. Our Turning 65 Medicare guide walks through every deadline, or you can take our 2-minute quiz to get a personal game plan.
