Medigap Household Discount: Save 5-14% on Your Premiums

What Is the Medigap Household Discount?

The Medigap household discount is a premium reduction that most major Medicare Supplement carriers offer when two eligible adults live at the same address. It's one of the few discounts on Medigap policies that can meaningfully reduce your monthly cost, and it typically ranges from 5% to 20% off the base premium depending on the carrier and state.

Because Medigap benefits are federally standardized (a Plan G from one carrier covers the same things as a Plan G from another), premiums and discounts are where carriers actually compete. The household discount is filed with each state's insurance department, so the exact percentage and eligibility rules can vary by carrier, plan, and ZIP code.

Unlike Medicare Advantage, where the government sets many rules, Medigap premium pricing structures are largely a private carrier decision. That is why shopping matters so much, and why a discount buried in fine print can be the difference between two otherwise identical quotes. The stakes are also higher in 2026 given the $202.90 standard Part B premium and $283 Part B deductible that beneficiaries pay on top of any Medigap premium.

Which Carriers Offer a Household Discount in 2026?

Almost every top-rated Medigap carrier offers some form of household discount, but the size varies significantly. Here is how the major national carriers stack up for 2026.

If you want carrier-specific detail, our full Mutual of Omaha review and Humana Medicare Supplement review walk through how each company applies the discount alongside base rates.

Why Mutual of Omaha and HealthSpring stand out

Mutual of Omaha's 12% household discount is one of the most generous in the industry, and its eligibility rules are among the most flexible. In many states the other adult does not even need to hold a Mutual of Omaha Medigap policy, though a handful of states use a 7% version that does require both people to enroll with the company. North Dakota sits at 10%. The exact tier is set by state filing, and the discount is unavailable in nine states including New York and Florida. Mutual of Omaha does not sell Medigap in Massachusetts at all.

HealthSpring (the rebranded Cigna Medigap block now under HCSC after the January 1, 2026 brand transition) markets savings of up to 25% when stacking discounts. Cigna's corporate guidance describes the base household discount as up to about 7% in most states, but broker rate reviews have found 10% to 20% for people living with a spouse in some states. Layer on the 5% online enrollment discount in eligible states and you can reach the 25% figure the carrier advertises. Independent 2026 analysis found HealthSpring's household discounts averaged about 15% across a wide sample, the highest of any national carrier tracked. Our full Cigna Medicare Supplement review covers the HCSC transition and the stacked-discount rules in more depth.

Do You Have to Be Married?

This is the single biggest misconception about the Medigap household discount. In many cases, no, you don't have to be married.

Carriers use different definitions of "household," and the rules generally fall into three buckets:

1. Marriage or legal partnership required

Some carriers (Aetna is a common example) require the two applicants to be spouses, civil union partners, or registered domestic partners in certain states. In these cases, both people typically must be Medicare-eligible and enroll with the same underwriting company. Aetna's national guidelines also allow any two Medicare-eligible adults who have lived at the same address for at least 12 continuous months, but individual state filings can be stricter.

2. Any adult co-resident with age or duration rules

Many carriers will grant the discount if you have lived with another qualifying adult (often age 50, 60, or Medicare-eligible) for at least 12 continuous months. Mutual of Omaha, for example, generally allows up to three adults age 60 or older to count toward eligibility. The other person can be:

• A sibling
• An adult child
• A roommate
• A significant other or domestic partner
• Any long-term co-resident meeting age rules

3. Any adult in the household, no relationship required

A few carriers, and some Blue Cross Blue Shield state plans, apply the discount simply because you and another Medigap policyholder live at the same single-family home, condo, or apartment. BCBS Michigan, for example, defines a household as a single-family home, condominium unit, or apartment unit, and does not require the co-resident to be a relative. The other person just needs to hold a Blue Cross Medicare Supplement or Legacy Medigap plan.

Do Both People Need the Same Carrier?

Usually yes, but not always. Here is how it typically works:

Even when the same-carrier rule applies, you and your spouse do not need to pick the same plan letter. One of you can enroll in Plan G while the other picks Plan N, and both policies still receive the household discount. That flexibility matters if one of you wants richer coverage and the other prefers lower premiums.

How the Household Discount Stacks With Other Savings

The household discount is often just the starting point. Most carriers allow it to combine with several other discounts, which is where the real savings show up.

Common stackable discounts include:

• Electronic funds transfer (EFT) / autopay, usually $2 per month (Humana pays $2/month for ACH)
• Annual or semiannual pay discount, a small percentage off for paying in bulk
• Non-tobacco rate, standard preferred pricing for non-smokers
• Online enrollment discount, Humana offers 6% (excluded in CA, CT, OH, PA); HealthSpring offers 5%
• New-to-Medicare discount, a few states offer a first-year discount
• AARP multi-insured discount, applies when two or more AARP members are enrolled under the same membership number and each holds an eligible AARP-branded Medigap policy (cannot be combined with the AARP household discount)

At its best, a HealthSpring policyholder in a state that allows both a 20% household discount and the 5% online discount can stack them for roughly 24% off the base premium. On a $166 Plan G base premium, that works out to about $40 per month per person, or nearly $500 per year, per person.

State-by-State Variations

There is no federal rule requiring carriers to offer a household discount, and no federal rule banning it either. Every discount is a carrier filing approved by the state, which means availability varies in three ways:

1. Which carriers sell in your state. Mutual of Omaha does not sell Medigap in Massachusetts, for example, so its household discount is not an option there.
2. How the carrier defined the discount in that state's filing. The same carrier might use different residency, age, or percentage rules in different states.
3. How state-specific rules interact. Massachusetts, Minnesota, and Wisconsin use standardized plan structures that differ from the other 47 states, which can affect discount availability.

Common state exclusions

• Mutual of Omaha's household discount is not offered in AK, CT, DC, FL, HI, ID, MN, NY, or VT.
• Humana's 6% online enrollment discount (which stacks with household savings) is not available in California, Connecticut, Ohio, or Pennsylvania. On the base Humana Medigap plan, some states show no household discount at all (for example, New York), while others show the 12% Enhanced Household Discount only on Humana Achieve.
• HealthSpring's household discount is not available in Hawaii or Vermont, and Washington uses a spousal-only version. Its 5% online discount is excluded in CT, DC, FL, MA, NJ, NY, OH, OR, and VT.
• AARP/UnitedHealthcare's household discount (up to 10%) is only available where filed, and it cannot be combined with the multi-insured discount. In many states, plain UnitedHealthcare Medigap does not offer a comparable household discount at all.
• Community-rated states like New York already price Medigap uniformly, which reduces or eliminates the size of some carrier discounts.

The bottom line: always confirm the specific discount rules in your state before assuming a national average applies.

How Much Can a Household Discount Actually Save You?

Let's put real numbers to it. The 2026 national average Plan G premium at age 65 is about $165.85 per month, rising to roughly $205 per month at age 75 and $267 at age 85. Here is what household discounts of different sizes would save a couple at age 65.

At age 75, where the national Plan G average rises to about $205 per month, a 12% household discount saves a couple roughly $590 per year. Over 10 years of coverage, that is nearly $6,000 in household savings, and that is before adding autopay or annual-pay discounts on top.

Using the Discount as a Tiebreaker

When you are comparing quotes from similarly priced carriers, the household discount can shift the winner. Here is a practical approach:

1. Get quotes from at least three carriers using your ZIP code, ages, and tobacco status.
2. Ask each carrier or broker for the net premium after household discount, not just the base rate.
3. Confirm the discount's residency requirements and same-carrier rules apply to your situation.
4. Factor in how likely the discount is to remain in place (for example, if a roommate might move out).
5. Check whether other discounts (autopay, annual pay, online enrollment) stack on top.

For couples specifically, remember that you do not have to pick identical plans. One spouse can enroll in an AARP/UnitedHealthcare Plan G while the other picks a different plan letter, and both still qualify for the household discount if the carrier allows different plans under the same policyholder rules. Just be sure to verify same-carrier eligibility before assuming both discounts will apply.

Also consider the carrier's rate stability. A 12% household discount is less valuable if the carrier files 20% rate increases every year. According to Telos Actuarial, early-2026 Plan G rate hikes among the six largest Medigap carriers ranged from just over 12% to more than 26%, and the firm's Q3 2026 update put the industry-wide Plan G average at 16.8%. That is why picking a top-ranked Medigap carrier with disciplined pricing matters as much as the initial discount, and our full Medicare Supplement cost guide walks through why rate history is worth just as much scrutiny as the discount itself.

Frequently Asked Questions

Do I have to be married to get a Medigap household discount?

No, not with most carriers. Many companies extend the discount to any two adults living at the same address, though most require age thresholds (often 50 or 60) and a minimum co-residency period of 12 months. Aetna is one common exception, as its state filings often limit the discount to a spouse, civil union partner, or domestic partner unless you have lived at the same address for at least 12 continuous months.

What happens to my discount if my spouse or roommate moves out?

The household discount will end and your premium will increase to the standard rate. You are typically required to notify your carrier of the change in living situation. Humana, for example, removes the discount when the qualifying spouse or other adult no longer lives with you, except in the case of death.

Can I get a household discount if my spouse isn't on Medicare yet?

It depends on the carrier. Some, like Mutual of Omaha in many states, extend the discount as long as you live with another adult meeting age criteria, regardless of Medicare enrollment. Others, like Aetna, require both people to be Medicare-eligible and hold Medigap policies with the same company.

Do both spouses need the same Medigap plan letter?

No. You and your spouse can pick different plan letters (for example, Plan G and Plan N) from the same carrier and still receive the household discount on both policies. This flexibility helps couples balance coverage needs with premium budgets, and it can be especially valuable if one spouse is a strong candidate for High Deductible Plan G while the other prefers standard Plan G.

Can I stack the household discount with other savings?

Usually yes. Most carriers allow the household discount to combine with autopay/EFT, annual-pay, non-tobacco, and online enrollment discounts. Total stacked savings can reach 20% to 25% with carriers like HealthSpring, though a few insurers restrict certain combinations (for example, AARP/UnitedHealthcare does not allow its household discount and multi-insured discount to be combined). Always confirm with your carrier or broker before enrolling.
