Best Medicare Supplement Plans in Alabama 2026
Alabama has over 220,000+ Medigap enrollees. Plan G starts at $133/mo in Birmingham and averages $191/mo statewide. We compared 30+ carriers to find the best coverage in the Heart of Dixie.
Alabama Has No Birthday Rule: Your Initial Plan Choice Matters
Unlike California, Oregon, and other states with birthday rules, Alabama does not give you an annual window to switch Medigap carriers without underwriting. Once your 6-month Open Enrollment Period ends, you will face health questions if you try to change plans. Compare carriers carefully before you enroll and consider long-term rate stability, not just today's lowest premium.
More than 220,000 Alabamians have Medicare Supplement Insurance, also called Medigap. Alabama follows standard federal Medigap rules, offering plans A through N with no state-specific modifications. Plan G is the most popular choice for new enrollees, covering nearly all Medicare out-of-pocket costs except the annual Part B deductible ($283 in 2026).
Alabama does not have a birthday rule or anniversary rule, which means your 6-month Open Enrollment Period when you first turn 65 and enroll in Part B is your best and most important opportunity to lock in coverage. After that window closes, carriers can use medical underwriting to deny your application or charge higher premiums based on your health history.
Plan G premiums in Birmingham range from $133/mo (USAA, military only) to $232/mo (Transamerica) for a 65-year-old. Mutual of Omaha and MedMutual Protect both offer Plan G at $148/mo and are the top picks for most Alabama seniors. State Farm stands out with an A++ AM Best rating and a large local agent network across Birmingham, Huntsville, Mobile, and Montgomery.

Plan G vs. Plan N in Alabama
Plan G and Plan N are the two most popular Medicare Supplement plans for new enrollees in Alabama. Here is how they compare.
| Coverage Feature | Plan G | Plan N |
|---|---|---|
| Part A hospital coinsurance | Covered | Covered |
| Part B coinsurance (20%) | Covered | Covered* |
| Part A deductible ($1,736) | Covered | Covered |
| Part B deductible ($283) | Not covered | Not covered |
| Part B excess charges | Covered | Not covered |
| Skilled nursing coinsurance | Covered | Covered |

Alabama has no birthday rule, so your initial enrollment decision is the most important one you will make. Do not just pick the cheapest premium today. Consider long-term rate stability: attained-age plans (most carriers) will increase every year as you age, while United American uses issue-age pricing that locks in your rate at enrollment. For most Alabama seniors, Mutual of Omaha at $148/mo is the best overall value: A+ rated, low complaint ratio, and a 7% household discount. If you or your spouse served in the military, USAA at $133/mo with an A++ rating is the clear winner. State Farm is the best pick if you want the highest financial strength rating (A++) and prefer working with a local agent in Birmingham, Huntsville, or Mobile.
Alabama Medigap Rules You Should Know
No Birthday Rule or Anniversary Rule in Alabama
Alabama does not have a birthday rule or anniversary rule. Outside of your 6-month Open Enrollment Period when you first turn 65 and enroll in Part B, you will face medical underwriting if you try to switch Medigap carriers. This makes your initial plan choice especially important.
Standard 6-Month Open Enrollment Period
Federal law gives you a 6-month Open Enrollment Period starting the month you turn 65 and enroll in Medicare Part B. During this window, no carrier can deny you coverage or charge higher premiums due to pre-existing conditions. This is the best time to enroll.
Under-65 Coverage Not Required
Alabama does not require Medigap carriers to offer coverage to Medicare beneficiaries under age 65 (such as those with disabilities). If you are under 65 and on Medicare, you may have difficulty finding Medigap coverage in Alabama. Some carriers offer it voluntarily at higher rates.
Attained-Age Rating Dominates
Most Alabama Medigap carriers use attained-age rating, meaning your premium increases as you get older. United American is a notable exception, using issue-age rating where your premium is locked at the rate for your age when you enroll. Issue-age plans often start higher but can be cheaper over the long term.
Excess Charges Are Allowed in Alabama
Alabama does not ban Medicare excess charges. Providers who do not accept Medicare assignment can charge up to 15% more than the Medicare-approved amount. Plan G covers these excess charges; Plan N does not. If your doctors do not accept Medicare assignment, Plan G is the safer choice.
Free Help via Alabama SHIP
Alabama's State Health Insurance Assistance Program (SHIP) provides free, unbiased Medicare counseling. Call 1-800-243-5463 to speak with a trained counselor who can help you compare plans, understand your rights, and enroll. There is no cost and counselors do not sell insurance.
