Best Medicare Supplement Plans in Alabama (2026)

Alabama seniors aged 65 can find Medigap coverage starting at $80 a month. The cheapest plans in the state save between $18 and $108 per month off average state rates, depending on which plan type best fits your coverage needs.

When we pulled rates across all 10 plan types for 65-year-olds in Alabama using the Medicare.gov plan browsing tool, one pattern emerged clearly: the savings gap between the cheapest insurer and the state average is largest for Plans C and N, where New Era and MedMutual Protect costs $108 and $71 per month. Plan M savings are the smallest at $18 per month.

Transamerica has the lowest rates on three plans: Plan K at $80 per month, Plan L at $119 and Plan B at $213. United American covers Plan A and New Era covers Plans C and M. State Farm has Plan D, USAA sells Plans F and G and MedMutual Protect covers Plan N.

Your specific needs may call for different coverage than what's popular. Use the filterable table below to find the best Alabama Medicare Supplement company that matches your situation.

For 65-year-olds in Alabama, Medicare Supplement premiums range from $99 to $289 per month, depending on the plan. Plan K is the cheapest at $99 per month, and Plan C is the most expensive at $289 per month.

Plan G, the most popular option in the state, averages $191 per month. Plan N runs $179 per month, Plan L is $158 per month and Plan M is $129 per month.

The $190-per-month spread between Plan K and Plan C reflects what you're buying. Plan C covers nearly everything including the Part B deductible. Plan K covers 50% of most costs after Medicare pays, with an $8,000 annual cap.

Plan C is the stronger pick when annual out-of-pocket costs under Original Medicare exceed $2,292, which is Plan C's average annual premium in Alabama. Seniors who are healthy and rarely see specialists often come out ahead with Plan K, particularly in the early years of enrollment.

Medicare Supplement plans are standardized by federal law, so Plan G from Transamerica covers exactly the same benefits as Plan G from State Farm. Companies compete on price for identical coverage. We analyzed rates across every plan type in Alabama and found that the cheapest insurer for one plan type is rarely the cheapest across all plans. Matching your plan type to your care needs is the first decision; finding the lowest price for that plan type is the second.

USAA has the lowest Plan G rate in Alabama at $133 per month, but it's available only to military members, veterans and eligible family members. MedMutual Protect at $148 per month is the strongest option for everyone else, $43 below the state average with a 4.9/5 affordability score among providers we reviewed.

Transamerica's Plan K at $80 per month is the lowest Medigap rate in Alabama. You pay 50% of covered costs up to the $8,000 annual limit, so Plan K suits healthy seniors who rarely use care. A 65-year-old who avoids hospital stays for a year saves $816 compared to MedMutual Protect's Plan G.

Rate stability is the variable most Alabama seniors underweight at enrollment. Seven of the 10 cheapest plans use Attained Age Pricing, which raises premiums each year as you age. United American is the one provider here with Issue Age Pricing across its full lineup. Your rate locks at enrollment and doesn't move with age.

MoneyGeek collected premium data for all Medicare Supplement plans available in Alabama for 65-year-olds and 75-year-olds using the plan browsing tool at Medicare.gov, pulling rates for a nonsmoker female profile to produce consistent comparisons across all 10 standard Medigap plan types.

We scored Medigap companies in Alabama based on three main categories to create a weighted score out of 5:

• Affordability (50%): Providers with the lowest monthly cost score higher.
• Pricing style (20%): Medigap insurers use three methods to determine premiums: Community Pricing, Issue-Age Pricing and Attained Age Pricing. We gave higher scores for pricing styles that are more stable and equitable, as follows: Community Pricing 1.0, Issue-Age Pricing 0.8, Attained-Age Pricing 0.6. Using this scaling, a slightly higher-cost community-rated plan can still score higher overall than a cheaper but more volatile attained-age plan.
• Plan availability (30%): Providers with a wider range of plan types score higher, with weighted scoring given to the most popular plan types like Plan G, Plan F and Plan N.
