Medicare Supplement

Does Medigap in Clarksville Fit Your Medicare Setup?

Clarksville sits in Montgomery County, and the Medigap options a person can buy here are set by federal rules and Tennessee's insurance market — not by ZIP code. If you have Original Medicare and want help paying the shares it leaves behind, a Medicare Supplement policy (Medigap) is one way to do it. The good news for local shoppers: the plan letters are standardized, so once you understand the letters, comparing offers gets a lot simpler.

What Medigap is — and what it is not

Medigap is private insurance that helps pay some of the out-of-pocket costs Original Medicare leaves you with, like coinsurance and copays. It only works if you are enrolled in Part A and Part B. You cannot use a Medigap policy with a Medicare Advantage plan, and Medigap does not cover prescription drugs. That is why most Medigap members also enroll in a stand-alone Part D drug plan.

Medigap plans are labeled with letters (A, B, D, G, and so on). The federal government sets what each letter covers, so a Plan G from one company covers the same core benefits as a Plan G from another company. What can differ is the monthly premium, the company's customer service, and extras a carrier may add on.

Which plan letters you can buy in Tennessee

If you are newly eligible for Medicare today, the standardized letters available in Tennessee are:

• Plan A
• Plan B
• Plan D
• Plan G (and a high-deductible version, G-HD)
• Plan K
• Plan L
• Plan M
• Plan N

Plans C and F are closed to anyone whose Medicare eligibility began on or after January 1, 2020. If you were eligible before that date, you may still be able to buy them.

Tennessee follows the federal standardized letters. (Massachusetts, Minnesota, and Wisconsin standardize Medigap differently — but that does not affect Clarksville.)

The insurers offering Medigap in Tennessee

Many companies sell Medigap in Tennessee, and each one offers a different mix of the standardized letters. Some offer only a few letters; others sell most of them. The table below lists every insurer and the plans each one sells in the state.

A few examples of the range: BlueCross BlueShield of Tennessee sells Plans A, C, D, F, G, and N. Farm Bureau Health Plans sells Plans A, D, G, and N. AARP – UnitedHealthcare Insurance Company sells Plans A, B, C, F, G, K, L, and N. United American Insurance Company sells one of the widest lineups, including Plans A, B, C, D, F, F-HD, G, G-HD, K, L, and N. This is not a ranking — it just shows why comparing the same plan letter across several carriers matters.

How Medigap pairs with Part D

Because Medigap does not cover prescription drugs, most Clarksville residents who choose Medigap also enroll in a stand-alone Part D plan. A few 2026 Part D facts worth knowing:

• The Part D out-of-pocket cap is $2,100 for 2026.
• The Part D maximum deductible is $615.
• The old coverage gap ("donut hole") was eliminated in 2025; Part D now has three phases.
• The Medicare Prescription Payment Plan lets you spread drug costs across the year in monthly payments instead of paying at the pharmacy counter.

If you have higher income, IRMAA surcharges can raise your Part B and Part D premiums; those begin above $109,000 for a single filer in 2026.

Timing and your right to buy without underwriting

The single most important date for Medigap is the start of your 6-month Medigap Open Enrollment Period. It begins the month you are 65 or older AND enrolled in Part B. During that window, insurers must sell you any Medigap plan they offer at their best available rate, regardless of health.

After that window, in most cases insurers can use medical underwriting to decide whether to sell you a policy and at what price. There are limited federal "guaranteed issue" rights — for example, if a Medicare Advantage plan leaves your area or you lose other coverage. Tennessee does not currently have a "birthday rule" like some states, so it is worth confirming your rights with an official source before you switch.

Note: Medigap enrollment is not tied to the fall Annual Enrollment Period (October 15 – December 7) or the Medicare Advantage Open Enrollment Period (January 1 – March 31). Those windows apply to Medicare Advantage and Part D. You can apply for Medigap any time of year — but outside a protected window, approval is not guaranteed.

How to compare offers in Clarksville

A practical way to shop:

1. Pick the letter first. Decide which standardized plan letter fits your budget and how much cost-sharing you are comfortable with. 2. Then compare carriers on that letter. Because the benefits are the same by law, differences come down to premium, rate history, and service. 3. Ask about how the company raises rates over time — this is where the state rate guide helps. 4. Confirm your Part D plan separately each fall during the Annual Enrollment Period.
