Aetna vs. Humana Medicare Supplement Plans

Choosing a Medicare Supplement plan can feel overwhelming at first. The benefits are standardized, the pricing varies widely, and every company claims to offer strong value.

When coverage is identical, the real decision often comes down to:

• Cost
• Service
• Long-term reliability

Two Medigap carriers that frequently come up in side-by-side comparisons are Aetna and Humana. Both are major national insurers. Both serve large numbers of Medicare beneficiaries. And both have historically appealed to price-conscious shoppers looking for solid coverage without paying top-tier premiums.

But their value propositions are not the same. Before we dig into premiums and positioning, here’s where each company stands in 2026.

Premium Comparison and Pricing (2026)

If you’re choosing between Aetna and Humana, this is the section that matters most. Remember, coverage is standardized. Pricing is not. Over 10 to 20 years, small monthly differences can add up to thousands of dollars.

National Premium Comparison (Age 65, Non-Smoker)

Let’s look at Plan G, the most popular plan.

That difference may not sound dramatic at first. But over 10 years, a $62 monthly gap becomes more than $7,440.

For Plan N, the national average is about $181 per month.

• Aetna typically falls in the $150 to $220 range.
  
• Humana often lands between $100 and $190 per month, again trending below average.
  

Both carriers price High-Deductible Plan G similarly, usually $45 to $70 per month. With a $2,950 deductible in 2026, your total annual exposure could reach roughly $3,500 to $4,000 if you fully use care. If you stay healthy, your annual premium cost might be just $540 to $840.

Regional Price Variations

Premiums shift significantly by location. Factors include:

• ZIP code and local healthcare costs
  
• Age and gender
  
• Tobacco use
  
• State regulations
  
• Rating methodology
  

Some examples for Plan G at age 65:

In general, the Midwest and parts of the South (excluding Florida) tend to have lower premiums. Urban areas usually run 10 to 20 percent higher than rural areas.

Overall, Aetna currently holds a pricing advantage in many markets, especially for Plan G. Humana’s premiums tend to run above the national average. If budget and long-term cost stability are priorities, Aetna often comes out ahead.

Discounts and Savings Opportunities (2026)

Premiums are important, but discounts can narrow the gap or widen it. It’s worth looking at what’s actually available in your state.

Aetna's Discounts

Household discount: Aetna offers a 7 percent discount in most states when two Medicare-eligible members of the same household enroll at the same time. Both applicants typically must apply together.

On a $281 Plan G premium, 7 percent equals about $20 per month in savings.

Electronic payment discount: n/a

12-month rate guarantee: Aetna typically locks your premium for the first year, protecting you from increases during that initial period.

Member perks: This is not a premium discount, but it can provide real value. Members can receive up to 25 percent off wellness products and services, including gym memberships, fitness programs, vision and hearing services, and even acupuncture or chiropractic care.

If you actively use it, the savings could add up to several hundred dollars a year.

Humana's Discounts

Household discount: Humana offers a 12 percent discount in most states, depending on whether you live with or enroll alongside a Medicare-eligible member of the same household.

On a $219 Plan G premium, that’s about $26 per month, or $315 per year.

Automatic payment discount: Most states offer a $2 per month discount for autopay, saving about $24 annually.

Valuable extras: EyeMed Vision care discounts, discounts through HearUSA and TruHearing, Humana Well Dine (14 nutritious meals delivered after an overnight stay in a hospital or nursing facility), 24/7 nurse advice line and SilverSneakers.

‍

Discount Comparison

Both carriers offer similar total discount potential. The difference is the starting premium.

In terms of added perks, Aetna offers member perks, while Humana includes programs like SilverSneakers in many areas. The value depends on whether you’ll actually use them.

Why Compare These Two?

When you’re shopping for a Medicare Supplement plan, you’ll often see Aetna and Humana appear near the top of quote comparisons. That’s not by accident.

Both are national carriers with widespread availability. Aetna operates in 44 states plus Washington, D.C. Humana is available in 48 states plus D.C. through multiple subsidiaries. Both have large Medicare member bases and strong financial strength ratings.

And both tend to appeal to budget-conscious Medicare beneficiaries who want recognizable brand names without paying the absolute highest premiums in the market.

On the surface, they look similar. But once you dig deeper, the differences become clear.

Humana is more recently positioned as a lower-premium option. In many ZIP codes, its premiums for Plan G and Plan N are below the national average. However, it's important to note that Humana has not always prioritized being the lowest-priced carrier. As a result, in the long term, their premiums are likely to remain closer to the national average but more steady and consistent.

Aetna, on the other hand, often charges higher premiums. Plan G pricing currently runs above the national average. In exchange, Aetna promotes wellness perks and other value-added programs.

However, it also faces serious customer service criticism, with some industry analyses ranking it among the weakest performers in that area.

So in reality, neither carrier is known for exceptional service. The real comparison becomes this:

Do you prioritize lower monthly premiums? Or are you willing to pay more for added perks and brand familiarity?

Comparing Aetna and Humana helps illustrate an important Medigap lesson. When coverage is standardized, the decision often comes down to trade-offs between price and extras. It also reinforces why shopping multiple carriers matters.

Even two large national brands can deliver very different value depending on what you’re looking for.

Current Availability

When you’re comparing Medigap carriers, availability matters just as much as price. Not every company operates in every state, and that can shape your options quickly.

Aetna currently offers Medigap coverage in 44 states plus Washington, D.C., covering about 1 million beneficiaries. That’s roughly 7 percent of the total Medigap market. However, Aetna is not available in Massachusetts because that state use their own standardized Medigap systems. Washington is also not included.

In most states, you’ll need to work with a licensed agent to get a quote.

Humana, on the other hand, has a broader footprint. It operates in 48 states including Massachusetts as well D.C. through various subsidiaries.

In short, Humana has slightly wider reach, but Aetna’s footprint is very strong.

Medicare Supplement Plans Offered

Before we compare Aetna and Humana side by side, it helps to remember one key fact: Medigap plans are federally standardized.

That means a Plan G from Aetna provides the exact same medical coverage as a Plan G from Humana. The benefits don’t change from company to company. What does change is the monthly premium, customer service, financial strength, claims experience, and any extra perks they include.

For most people enrolling after January 1, 2020, Plan G is the most popular option. Plan N is a lower-cost alternative with some copays. And High-Deductible Plan G offers the lowest premiums in exchange for a $2,950 deductible in 2026.

Aetna Plan Portfolio

Aetna offers seven Medigap plan types, depending on your state:

• Plan A
• Plan B (limited availability)
• Plan C (only for those eligible for Medicare before 2020; available in select states like New Jersey)
• Plan D (select states; often competitively priced)
• Plan F (pre-2020 eligible only)
• High-Deductible Plan F (pre-2020 eligible only)
• Plan G
• High-Deductible Plan G ($2,950 deductible in 2026)
• Plan N

Notably, Aetna does not offer Plans K, L, or M.

Humana Plan Portfolio

Humana generally offers a slightly broader selection, depending on the state and subsidiary:

• Plan A
• Plan B
• Plan C (pre-2020 eligible, select states)
• Plan D
• Plan F and High-Deductible Plan F (pre-2020 eligible only)
• Plan G
• High-Deductible Plan G ($2,950 in 2026)
• Plan K (cost-sharing plan, select states)
• Plan L (cost-sharing plan, select states)
• Plan N

Humana typically offers 8 to 10 plan types and includes Plans K and L, which Aetna does not.

A Closer Look at the Most Popular Plans

Plan G is the most comprehensive option available to new Medicare beneficiaries. It covers Part A hospital coinsurance (including 365 extra days after Medicare runs out), Part B coinsurance (usually 20%), skilled nursing facility coinsurance, hospice coinsurance, the Part A deductible ($1,736 in 2026), Part B excess charges, and limited foreign travel emergencies.

The only thing it doesn’t cover is the Part B deductible, which is $283 in 2026.

Plan N offers similar protection but does not cover the Part B deductible or excess charges. You’ll also pay up to $20 for some office visits and $50 for ER visits if you’re not admitted. It works well for people who don’t see doctors often and want lower premiums.

High-Deductible Plan G requires you to pay $2,950 out of pocket before coverage for your portion of the Medicare cost share kicks in. After that, it functions like standard Plan G. Monthly premiums are much lower, often in the $45 to $70 range compared to $220 to $280 for regular Plan G. It’s typically best for very healthy individuals who want protection mainly for major medical events.

Customer Service and Claims Experience (2026)

Customer service is where both Aetna and Humana struggle. If service quality is your top priority, neither carrier stands out in a positive way.

Aetna Customer Service

Aetna receives 2.5 out of 5 stars from NerdWallet for Medicare Supplement plans. Its NAIC Complaint Index is 2.77, meaning it receives significantly more complaints than expected for its size. That’s well above the industry average of 1.00.

Common complaints include:

• Long hold times, sometimes reported at one hour or more
  
• Billing confusion
  
• Claims delays
  
• Difficulty reaching representatives
  

On the positive side, Aetna holds an A rating from the BBB, which suggests it responds to and works to resolve complaints. Its medical loss ratio of 89.1% is well above the industry average, meaning more premium dollars go toward member care.

Digital tools are available, including an online portal and claims tracking. However, online quoting and enrollment are limited in most states.

Overall, Aetna’s service reputation is below average, but not the worst in the industry.

Humana Customer Service

Humana also earns 2.5 out of 5 stars from NerdWallet. However, its complaint data is more concerning. Reports show Humana’s complaint levels are multiple times higher than the industry average, placing it among the weaker performers in Medicare Supplement service.

Common issues include:

• Claims processing errors or delays
  
• Customer service frustration
  
• Premium increase concerns
  
• Enrollment and billing problems
  

Humana does offer a more robust digital experience through the MyHumana portal and mobile app. Members can track claims, access ID cards, and message support online. That’s generally stronger than Aetna’s digital access.

SilverSneakers and the 24/7 nurse line are well-liked benefits, but they don’t offset service concerns if a claims issue arises.

Overall Comparison

Both companies receive higher-than-average complaint levels. Aetna’s wait times are often criticized, while Humana tends to generate more claims-related complaints.

If forced to choose, Aetna appears slightly more stable from a complaint standpoint, though neither carrier excels in service.

One important note: Medigap plans require far less customer service interaction than Medicare Advantage plans. Most claims are automatically processed through Medicare. Still, when you do need help, service quality matters.

Financial Strength and Stability (2026)

When you buy a Medigap policy, you’re making a long-term decision. These plans are designed to stay with you for life, as long as you pay your premiums. So financial strength matters.

Aetna Financial Strength

Aetna (through the Aetna Health & Life Group) holds an A (Excellent) Financial Strength Rating from AM Best. That rating reflects a strong ability to pay claims and meet long-term obligations. S&P also assigns A-level ratings to major subsidiaries.

In simple terms, Aetna is financially solid. Its balance sheet is considered strong, and its capitalization levels are high.

Aetna is owned by CVS Health. While CVS has taken on debt from recent acquisitions and faced some legal settlements, those parent-company issues have not affected Aetna’s ability to pay claims. The insurance subsidiary itself remains well capitalized.

Aetna also maintains a high medical loss ratio, meaning a larger percentage of premiums goes toward member care rather than profit.

Humana Financial Strength

Humana also holds an A (Excellent) rating from AM Best for its insurance subsidiaries. That signals strong claims-paying ability.

That said, Humana’s capital position has faced more scrutiny. Reports note risk-adjusted capital at a weaker level compared to peers, largely due to growth pressures and challenges in its Medicare Advantage business.

However, Humana maintains strong cash flow, access to capital markets, and adequate reserves. There are no immediate concerns about its ability to meet claims obligations.

Bottom Line

Both Aetna and Humana are financially stable enough to support Medigap policyholders. Each carries an A-level rating and strong claims-paying history.

If choosing strictly on financial strength, Aetna appears slightly stronger on capital positioning, but both companies are considered safe choices from a solvency standpoint.

Enrollment Process and Underwriting (2026)

Timing is everything when it comes to Medigap enrollment. When you apply can matter more than which company you choose.

When to Enroll

The best time to enroll is during your Medigap Open Enrollment Period (OEP).

This window lasts six months and begins on the first day of the month when:

1. You are age 65 or older, and
   
2. You are enrolled in Medicare Part B.
   

During this period, you have guaranteed issue rights. That means:

• You cannot be denied coverage.
  
• You cannot be charged more because of health conditions.
  
• You do not answer medical underwriting questions.
  

For example, if you turn 65 in June and your Part B becomes effective June 1, your Open Enrollment Period runs from June 1 through November 30. You can apply anytime during that window and receive guaranteed acceptance.

This is often the only time you can enroll in any Medigap plan without health screening. It’s critical not to miss it.

Outside the Open Enrollment Period

If you apply after your six-month window ends, both Aetna and Humana typically require medical underwriting in most states.

That means:

• You must answer health questions.
  
• You can be denied based on certain conditions.
  
• You could be charged a higher premium.
  
• In some cases, a pre-existing condition waiting period of up to six months may apply.
  

Humana is often considered stricter in underwriting outside OEP, but both carriers evaluate health history carefully.

Guaranteed Issue Rights (Special Situations)

You may also qualify for guaranteed issue protections if you:

• Lose employer or union coverage
  
• Have a Medicare Advantage plan that ends or leaves your area
  
• Move out of your plan’s service area
  
• Lose coverage due to insurer bankruptcy
  

In those cases, you typically have 63 days to enroll in a Medigap plan without underwriting.

Bottom line: If you’re turning 65 and starting Part B, that six-month window is your safest and simplest opportunity.

Pros and Cons Summary (2026)

Here’s a straightforward breakdown of where each company stands.

Aetna's Pros

Aetna’s biggest advantage is brand recognition and stability. With Plan G averaging around $281 per month at age 65, it comes in slightly above the national average and well above Humana in many states. Some plans, like Plan D in select markets, are priced under national averages.

In five states, Aetna uses issue-age rating, which can mean more predictable long-term pricing. It also offers a 12-month rate guarantee, so your premium won’t increase during your first year.

Discounts are solid. A 7 percent household discount can reduce premiums meaningfully. The Member perks add extra value if you actively use gym, vision, or hearing discounts.

Financially, Aetna is strong, holding an AM Best A (Excellent) rating and a high medical loss ratio, meaning more premium dollars go toward care. Policies are guaranteed renewable and work with any Medicare-accepting provider nationwide.

Underwriting is generally viewed as somewhat more flexible than Humana outside Open Enrollment.

Aetna's Cons

Customer service is Aetna’s weak point. Its complaint index is well above average, and long hold times are common complaints. Also, their premiums are currently running above the national average.

Most states use attained-age pricing, so premiums increase as you age. Annual increases of 5 to 10 percent are common industrywide.

Aetna also does not offer Plans K, L, or M, so plan selection is slightly narrower.

Humana's Pros

Humana has broader geographic availability and typically offers more plan options, including Plans K and L.

Its value-add benefits are appealing. SilverSneakers gym access can be worth several hundred dollars per year if used. The 24/7 nurse advice line and vision discounts are also popular.

Humana provides easier online enrollment and stronger digital tools than Aetna. Financially, it also carries an AM Best A (Excellent) rating, and policies are guaranteed renewable with nationwide provider access.

Humana's Cons

Humana also shows higher complaint levels, particularly around claims processing and customer service. Premium increases and strict medical underwriting outside Open Enrollment are common concerns.

Their past priority seemed to favor Medicare Advantage members, so their pricing has not always been competitive.

In short, Humana is currently winning on price, while offering broader plan variety and stronger digital access but neither company stands out for customer service.

Which Offers Better Value?

If we strip this down to dollars and practical use, the answer depends on how you personally weigh premiums versus perks.

Premium Value

At age 65, Plan G averages:

• Aetna: $281 per month
  
• Humana: $219 per month
  

That’s a $62 monthly difference, or $744 per year in Aetna’s favor. Over five years, that’s more than $3,720 in savings, not including rate increases.

With maximum discounts applied:

• Aetna: roughly $261 per month
  
• Humana: roughly $193 per month
  

Even after discounts, Humana is still about $68 per month cheaper.

Purely on premium, Humana clearly wins in most markets.

Do the Extras Close the Gap?

Aetna's benefits may seem impressive at first glance. The discounts on gym memberships, wellness products and services, fitness programs, as well as savings on vision and hearing services can accumulate and potentially offset some of the difference in premium costs.

But here’s the honest question: will you use them?

Many people sign up for gym memberships and rarely go. Wellness reward programs require consistent engagement.

Humana's value extras program can also generate savings if you actively purchase discounted services.

When Aetna Makes More Sense

Aetna usually offers better value if:

• You’re not price-focused
  
• You won’t regularly use a gym
  
• You qualify for the household discount
  
• You want lower long-term projected costs
  

When Humana Makes More Sense

Humana may be worth the extra cost if:

• You are price-focused
• You will actively use SilverSneakers
  
• You value online enrollment and digital tools
  
• You want access to Plans K or L
  
• The local premium difference in your ZIP code is small
  

Both companies have service weaknesses. Neither should be chosen without comparing at least several other carriers in your area.

The smartest move is to get personalized quotes, project five-year costs, and be honest about whether you’ll actually use the extra benefits.

If forced to choose strictly between these two, Humana usually offers stronger premium value, while Aetna can justify its higher cost only if you truly use the added perks, or brand recongition and name value are important to you.
