- Renewal assurance: We verified whether or not plans received a guaranteed renewal as long as premiums were consistently paid.
- State coverage and plan options: We examined the number of states where plans are offered, the variety, and how they stack up against competitors. We also looked at any state regulations or rules that might affect coverage.

Do I Need a Medigap Plan?
Before we get into the nitty-gritty of UnitedHealthcare plans, you may wonder why older adults need a Medigap plan in the first place. Well, as mentioned above, Original Medicare doesn’t cover everything. In fact, it only covers about 80 percent of the medical costs it approves. The remaining 20 percent is your responsibility. With no out-of-pocket maximum, predicting yearly medical expenses can be nearly impossible. Medicare supplement insurance helps protect more than 14.5 million people eligible for Medicare from high out-of-pocket costs not covered by Medicare.2
Let’s say you have a major surgery that costs tens of thousands of dollars. Paying 20 percent of that surgery can be quite a blow. That’s why about 89 percent of older adults supplement their Original Medicare with employer-sponsored coverage, Medicaid, or a Medigap plan like one from UnitedHealthcare.3

UnitedHealthcare offers a variety of Medigap plans endorsed by the AARP to meet of variety of needs and budgets.
Overview of UnitedHealthcare Medigap Plans
The federal government has created 10 standardized Medigap plans for private insurance companies to sell and UnitedHealthcare offers eight of them. We appreciate that UnitedHealthcare has a good variety of plans, as other companies we’ve reviewed, like HealthSpring, offer a more limited selection.

Which UnitedHealthcare Medigap Plan Is Right for Me?
Your lifestyle, health condition, and budget should be considered when selecting a Medigap plan from UnitedHealthcare. Each plan has its pros and cons, but we’ve gone ahead and highlighted a few we recommend for seniors based on those factors. Similar to Blue Cross Blue Shield, certain UnitedHealthcare Medigap plans come with discounts on dental, hearing, and vision, a free gym membership, and a 24/7 nurseline, though they aren’t available in all states.
Visit our UnitedHealthcare and senior care guide to learn more about the types of care this carrier’s plans will cover.
Seniors Who Want Basic Coverage
Recommended Plans: A or B
Designed to cover basic expenses not covered by Original Medicare, Medigap Plans A and B include hospital stays, home health care, and hospice care. Just be prepared to pay for Medicare Part B excess charges, emergency care when out of the country, and coinsurance while staying in a skilled nursing facility.
Seniors Who Rarely Visit the Doctor
Recommended Plans: F or G
Medigap plans F and G have high-deductible options. For older adults who are managing a chronic illness, this can be an ideal option. Frequent appointments and procedures allow you to meet your deductible and then begin receiving the benefits of the Medigap plan. Plan G is a popular Medicare supplement plan and helps cover Medicare Part A hospital expenses and services, the Part A deductible, and the Part B coinsurance.4
Seniors Seeking Broad Coverage Without Networks or Referrals
Recommended Plans: G and N
Danielle Kunkle Robertes notes that Medigap Plan G and Plan F are two of the most often recommended plans. Medigap Plans G and N are well suited for people who want predictable out-of-pocket costs and the freedom to see any doctor nationwide who accepts Medicare.
Plan G is often best for beneficiaries who prefer maximum coverage and minimal surprise expenses, while Plan N can be a good fit for those willing to pay small copays in exchange for lower monthly premiums. Both plans are especially popular with retirees who want long-term stability without provider networks or referrals.
How Much Do UnitedHealthcare Medigap Plans Cost?
Monthly premiums for Medigap plans are dependent on your geographic location, tobacco use, and gender. To give you a ballpark idea, we’ve provided the premium estimates for a 65-year-old nonsmoking male living in Orlando, Florida. In most states, UnitedHealthcare also offers a 5 percent household discount. To benefit from this discount, both spouses need to buy a Medigap policy.
| Plan | Monthly Price |
|---|---|
| A | $180.06 |
| B | $218.53 |
| C | Not available to seniors who were newly eligible for Medicare on or after January 1, 2020 |
| F | Not available to seniors who were newly eligible for Medicare on or after January 1, 2020 |
| G | $208.64 |
| K | $68.22 |
| L | $151.42 |
| N | $178.33 |
UnitedHealthcare Pricing Method
Health insurance companies price their Medigap policies using one of three methods: community-rated, issue-age-rated, and attained-age-rated.3 Keep in mind, not all states allow all three methods to be used. Here’s a quick definition of the three methods:
- Community-rated: Every senior in the community who has the Medigap policy is charged the same monthly premium regardless of age. This means your premiums may go up due to other factors like inflation, but not because of your age.
- Issue-age-rated: Your premium is based on the age you are when you purchase the Medigap policy – the younger you are, the cheaper your premium is. It is advantageous to buy a policy early from a company using this pricing method. Your premiums may still go up due to inflation.
- Attained-age-related: The premium is based on your current age at enrollment and increases as you get older. Premiums can also increase due to other factors, such as inflation.
Did You Know? States where companies can’t use age to determine pricing include Arkansas, Connecticut, Maine, Massachusetts, Minnesota, New York, Vermont, and Washington.5
UnitedHealthcare uses a community-rated pricing method in some states, which may appeal to older seniors, as your rates won’t increase with age. For comparison, competitors we’ve reviewed, like Humana, use an attained-age pricing method, which means the older you are, the more you’ll pay. UnitedHealthcare may offer better premiums to seniors in their 70s and beyond, and rates won't increase due to age.
How to Buy a UnitedHealthcare Medigap Policy
Enrolling in a UnitedHealthcare Medigap policy can be done with a few clicks from your computer. Or you can pick up the phone and call one of their friendly representatives to walk you through the process. They are available 8 a.m. to 8 p.m., seven days a week by phone. You also have the option to make an appointment to meet with a friendly agent in your area or use the live chat feature on the website.
We recommend purchasing a Medigap policy during your six-month Medigap open enrollment period. This will get you the best monthly premium prices and the most plans to select from. The six-month open enrollment period starts the month you enroll in Medicare Part B and are 65 or older.
Some people qualify for Medicare before the age of 65 due to disability. These people will get an initial six-month Open Enrollment Period starting with the Part B effective date. Later, when they turn 65, they will qualify for a second six-month window.
If you miss this six-month window, you may not be able to buy a policy, or it could be much more costly. So, mark your calendar! Missing this window could cost you big bucks in the long run.
