A Medigap household discount lowers your Medicare Supplement premium by roughly 5% to 12% when you share a home with a spouse, partner, or another qualifying adult. Most major carriers offer some version of it, and the exact savings, eligibility rules, and documentation vary by insurer and state. The discount changes only what you pay. It does not change what the plan covers, because federal law requires every Medigap policy with the same letter designation to provide identical benefits regardless of price.1CMS.

How the Discount Works
Insurers spend less on administration when multiple policyholders share an address, and they return part of that saving as a lower monthly premium. The discount is applied as a percentage. A 10% discount on a $180 monthly premium saves you $18 a month, or $216 a year. If both people in the household each hold their own policy with the same carrier, the discount often applies to both premiums, doubling the household’s total saving.
Carriers use one of two models, and this is worth confirming before you apply. The more common version requires that both residents hold active Medigap policies with the same insurance company. The second version is more flexible: it only requires that another qualifying adult live in your home, whether or not that person carries Medigap or any insurance at all.
Who Qualifies
Married couples and domestic partners are almost always eligible automatically. Many insurers also extend the discount to unrelated adults who have shared the same address for at least 12 continuous months.2Aetna Senior Products. Medicare Supplement Household Discount Qualification Guidelines
Age thresholds for the co-resident vary. Some carriers require the household member to be at least 18, while others set the floor at 50 or 60.3Nassau Life Insurance Company of Kansas. Medicare Supplement State Availability and Household Discount Requirements Mutual of Omaha, for example, offers a higher discount tier when the co-resident is a spouse or civil union partner, and a different tier when the applicant has lived with up to three adults age 60 or older for the past year.4Mutual of Omaha. Medigap Household Discount Map Confirm your carrier’s specific rule rather than assuming it matches another company’s.
Carriers also define “household” narrowly. A qualifying residence is a single-family home, condominium, or apartment unit. Assisted living facilities, nursing homes, group homes, and other residential care settings are excluded. If you or your co-resident moves into one of those facilities, the household discount no longer applies, even if the two of you still consider yourselves part of the same household.
High-Deductible Plan G, which carries a $2,950 annual deductible in 2026, can also qualify for household savings with some carriers.5CMS. CY2026 Medigap High Deductible Options Mutual of Omaha offers up to a 12% household discount on High-Deductible Plan G for applicants who live with a spouse or have shared a home with another adult for the past year.6Mutual of Omaha.

One geographic note: Massachusetts, Minnesota, and Wisconsin use their own non-standard Medigap plan structures instead of the familiar lettered system. If you live in one of those states, household discount availability and structure may differ from what national carriers advertise, so check directly with insurers licensed in your state.
How Much You Can Save
Based on carrier documentation, published discounts run from about 5% at the low end to 12% at the high end. Mutual of Omaha’s schedule shows a 7% discount in some states and 10% to 12% in others, with the higher tier reserved for spouses and civil union partners.4Mutual of Omaha. Medigap Household Discount Map Some carriers apply a flat percentage across all plans; others use tiers tied to plan letter or relationship.
Because the discount is a percentage rather than a fixed dollar amount, its dollar value rises with your premium. On a $250 monthly premium a 10% discount saves $300 a year; on a $150 premium that same 10% saves $180. The percentage is the number to track, not any single month’s dollar figure.
Pricing method matters too. Medigap premiums are calculated as community-rated, issue-age-rated, or attained-age-rated, and the discount sits on top of whichever your insurer uses.7Medicare.gov. Choosing a Medigap Policy A smaller discount on a community-rated policy can beat a larger discount on an attained-age-rated policy over five or ten years, because the attained-age premium climbs with your age. Compare the full projected cost, not just the first year.
How to Apply
Applying means proving your identity and your shared living arrangement. You’ll need the legal name, date of birth, and Medicare Beneficiary Identifier of the co-resident. For residency proof, carriers accept utility bills, lease agreements, or driver’s licenses showing the same address as your Medigap policy. Most insurers accept scanned copies or clear photographs submitted through online portals.
If you already hold an active Medigap policy, you can usually add the discount by contacting policyholder services or completing a household discount request form. This does not involve medical underwriting or health questions, because you’re adjusting the price on a policy you already own rather than applying for new coverage.8Aetna Senior Products. Medicare Supplement Household Discount Qualification Guidelines
New applicants face a different wrinkle. When two people in the same household apply simultaneously, some carriers will not issue either policy until both applications clear underwriting.8Aetna Senior Products. Medicare Supplement Household Discount Qualification Guidelines If one applicant is declined, the other may still receive a policy but without the household discount. Ask the carrier upfront how they handle paired applications.
Once approved, the discount shows up on your next billing statement as a reduced premium. If a request is denied, the carrier should give a specific reason, and the fix is often additional residency documentation or a correction to the original form.
Timing and the Risk of Switching Carriers
The best time to secure any Medigap policy is during your Medigap Open Enrollment Period, the six-month window that begins the first day of the month you turn 65 and are enrolled in Medicare Part B.9Medicare.gov. When Can I Buy a Medigap Policy? During that window, insurers cannot reject you or charge more because of your health. After it closes, you face medical underwriting, and a carrier can deny your application entirely based on your health history.
This matters most when someone considers switching carriers to chase a bigger household discount. Moving from a 7% discount at your current carrier to a 12% discount at another typically requires answering health questions and passing underwriting.10Medicare.gov. Can I Switch or Drop My Medigap Policy? A few percentage points of premium savings mean nothing if underwriting results in a denial and you lose coverage. If both members of a household are approaching 65 around the same time, coordinating enrollment during each person’s Open Enrollment Period with the same carrier locks in the discount from day one without any underwriting risk.
When Your Household Status Changes
Life changes affect eligibility, and the rules depend on your carrier. If your spouse or co-resident dies, some carriers let the surviving policyholder keep the discount indefinitely. Aetna’s guidelines, for example, state that the discount on the remaining policy continues if one policyholder dies or later cancels coverage.2Aetna Senior Products. Medicare Supplement Household Discount Qualification Guidelines Other carriers remove the discount after a grace period, and some end it immediately. Ask your carrier about its specific policy before you need the answer.
Divorce or a co-resident moving out works differently. Because the discount requires a shared address, the person who leaves the qualifying household typically loses it. You’re required to report residency changes to your insurer. Failing to do so can result in the carrier retroactively billing you for the full undiscounted premium once they discover the change, and months of back-billed differences add up quickly.
If a new qualifying person moves into your household, you can generally apply for the discount fresh once residency requirements are met. For non-spouse co-residents, that usually means waiting out the 12-month continuous residency period before submitting the request.2Aetna Senior Products.

Coverage Is Identical Regardless of Price
A Plan G policy purchased with a 12% household discount covers exactly the same costs as a Plan G policy purchased at full price from a different carrier.1CMS. Medigap (Medicare Supplement Health Insurance) The discount affects your premium and nothing else. No benefits are reduced, no copays change, no coverage gaps appear. Price differences between carriers reflect overhead, profit margins, and risk assessment, not differences in what the plan covers.
