Medicare Supplement

Plans C and F closed in 2020: what Huntsville has left

Huntsville shoppers looking at a Medicare Supplement policy — better known as Medigap — face a menu that looks confusing at first glance but is actually smaller than it seems. Federal rules standardize what each lettered plan covers, so a Plan G bought in Huntsville pays the same share of your Original Medicare costs as a Plan G bought anywhere else in Alabama. What changes from company to company is the price and the service, not the benefits inside the letter.

Huntsville is in Madison County, and Medigap in Alabama follows the federal standardized-plan system. That means the choice is really two decisions: which letter fits your budget and health, and which insurer to buy that letter from.

What Medigap is, and how it fits with Original Medicare

Medigap is private insurance that pays some of the out-of-pocket costs Original Medicare leaves behind — things like the Part A hospital deductible, coinsurance, and (with some letters) the Part B deductible. You have to be enrolled in Medicare Part A and Part B to buy one. Medigap does not work with Medicare Advantage; you pick one path or the other.

Medigap also does not include prescription drug coverage. Huntsville residents who choose Original Medicare plus a Medigap policy usually add a stand-alone Part D drug plan to round out coverage. For 2026, Part D has a $2,100 annual out-of-pocket cap and a maximum deductible of $615, and the old "donut hole" coverage gap has been eliminated. If drug costs are uneven month to month, you can also opt into the Medicare Prescription Payment Plan to spread them out.

The plan letters you can buy in Alabama today

Alabama uses the federal standardized Medigap lineup (unlike Massachusetts, Minnesota and Wisconsin, which run their own systems). If you are newly eligible for Medicare today, you can shop these letters:

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

Plans C and F are closed to anyone who became eligible for Medicare on or after January 1, 2020, because federal law no longer lets new Medigap plans cover the Part B deductible. If you were eligible before that date, you may still buy them.

Plan G is the most benefit-rich letter open to new enrollees. Plan N trades a slightly smaller benefit set for a lower typical premium. Plans K and L are cost-sharing designs with an out-of-pocket limit. The high-deductible version of Plan G asks you to meet a set deductible before the policy pays. Because the letters are standardized, the covered benefits inside each one are identical from company to company.

Which insurers sell Medigap in Alabama

The table below lists every insurer approved to sell Medigap in Alabama, along with which letters each one offers. A few carriers, like BlueCross BlueShield of Alabama, sell a narrow slice; others, like United American Insurance Company, offer nearly every letter still available. Names you will recognize on the list include AARP - UnitedHealthcare Insurance Company, AFLAC, Bankers Life, Continental Life Insurance Company of Brentwood, Tennessee (Aetna), Humana (Emphesys Insurance Company), Mutual of Omaha (Omaha Insurance Company), State Farm Mutual Automobile Insurance Company and USAA Life Insurance Company.

Because the benefits inside a letter are set by federal rule, comparing the same letter across insurers is the cleanest way to shop — you are comparing price, customer service and how the company raises rates over time, not the coverage itself.

The state rules that shape your choice

Two federal rules matter most in Alabama:

• Medigap Open Enrollment Period. You get a one-time, six-month window that begins the month you are 65 or older and enrolled in Part B. During this window, insurers must sell you any Medigap policy they offer at their best available rate, regardless of your health.
• Guaranteed issue rights. In certain situations — for example, losing other coverage through no fault of your own — federal law gives you a limited right to buy specific Medigap policies without medical underwriting.

Outside those windows, Alabama insurers generally can use medical underwriting when you apply, meaning your health history can affect whether you are approved and what you pay. Alabama does not have a statewide "birthday rule" like a few other states. For questions about state-specific consumer protections, contact the Alabama Department of Insurance or the Alabama SHIP (State Health Insurance Assistance Program), which offers free one-on-one counseling.

How to narrow it down

A practical order of operations for Huntsville shoppers:

1. Decide whether Original Medicare + Medigap + Part D is the path you want (versus Medicare Advantage). 2. Pick the letter that matches how you want to handle out-of-pocket costs — more premium and fewer surprises, or lower premium and more cost-sharing. 3. Compare that same letter across multiple insurers licensed in Alabama. 4. Ask each insurer how they price the policy (community-rated, issue-age or attained-age) and how often rates have changed. 5. Add a stand-alone Part D plan that covers your specific prescriptions.

Keep in mind that Medicare Advantage has its own enrollment calendar — the Annual Enrollment Period runs October 15 – December 7, and Medicare Advantage Open Enrollment runs January 1 – March 31 — but the Medigap six-month window is tied to your own Part B start date, not the calendar.
