You’re sitting at the kitchen table with a stack of mail that’s roughly the size of a phone book. Most of it is junk. But then there’s that one thick envelope with the AARP logo and the UnitedHealthcare name sitting side-by-side. It’s about Medigap.
Honestly, it's confusing.
Most people think AARP is the insurance company. It isn't. AARP is a massive advocacy group that basically "rents" its brand to UnitedHealthcare. If you buy aarp supplemental health insurance united healthcare, you’re actually getting a policy from UnitedHealthcare that AARP has given their seal of approval.
Why does this matter? Because the "AARP brand" doesn't just provide comfort—it changes how the plans are priced and what extras you get. In 2026, navigating this is even more critical as Part B deductibles and out-of-pocket limits have shifted again.
Why Medigap and Not Just Medicare?
Medicare is great, but it’s like a bucket with a few holes in the bottom. It covers a lot, but you’re still on the hook for that 20% coinsurance for doctor visits and some pretty hefty deductibles.
That’s where aarp supplemental health insurance united healthcare comes in. It sits on top of your Original Medicare (Parts A and B). It’s designed to "fill the gaps"—which is why everyone calls it Medigap.

One thing people get wrong constantly: you cannot have this and a Medicare Advantage plan at the same time. It’s one or the other. If you like the freedom to see any doctor in the country who takes Medicare, you go the Medigap route. If you want a "bundled" plan that feels like the insurance you had through an employer, you usually look at Advantage.
The 2026 Landscape: Plan G vs. Plan N
If you’re looking at these plans today, you’re probably seeing two heavy hitters: Plan G and Plan N.
Plan G is the current gold standard. It covers everything that Medicare doesn't, except for the Part B deductible. In 2026, that Part B deductible has climbed to $283. Once you pay that first $283 out of your own pocket for the year, Plan G kicks in and you shouldn't see another medical bill for Medicare-approved services. No copays. No coinsurance.
Plan N is for people who want to save a little on the monthly premium but don't mind a bit of skin in the game. You'll pay a lower monthly fee, but you’ll have a copay of up to $20 for some doctor visits and up to $50 for ER visits.
Kinda simple when you break it down like that.

The Secret Sauce: What Makes AARP Plans Different?
Standardization is the law. A Plan G from UnitedHealthcare is legally required to cover the exact same medical benefits as a Plan G from Blue Cross or Mutual of Omaha.
So why choose the aarp supplemental health insurance united healthcare option?
- The Network (or lack thereof): With these plans, there is no network. You can walk into any clinic from Maine to California as long as they accept Medicare. UnitedHealthcare is massive, so their claims processing is usually lightning-fast.
- The "Extras": This is where they compete. Many AARP/UHC plans include things like Renew Active, which is a gym membership program. They also throw in vision and dental discounts that you won't find on a "bare-bones" Medigap plan from a smaller carrier.
- Pricing Style: UHC often uses "community-rated" or "issue-age-rated" pricing depending on where you live. Community-rated means everyone in your area pays the same, regardless of age. This can be a huge win as you get older because your rates don't spike just because you had another birthday.
The "Fine Print" You Might Miss
You have to be an AARP member. It's about $16 to $20 a year. If you aren't already a member, UnitedHealthcare will usually let you join during the insurance application process.
Also, timing is everything.
If you apply during your Medigap Open Enrollment Period (the 6-month window starting the month you’re 65 and on Part B), they can't ask you health questions. They have to take you. If you wait and try to switch later, you might have to go through "medical underwriting." That's a fancy way of saying they’ll look at your health history and might charge you more—or even deny you—if you have pre-existing conditions.

Real Costs to Watch For
Let's look at the numbers for 2026.
- Part A Deductible: $1,736. (Plan G and N cover this entirely).
- Part B Deductible: $283. (You pay this out of pocket).
- Monthly Premiums: These vary wildly by ZIP code. In a low-cost area, you might see Plan G for $130. In a high-cost city, it could be $250 or more.
A common mistake? Choosing the cheapest plan without looking at "excess charges."
If a doctor doesn't accept "Medicare Assignment," they can charge up to 15% more than the Medicare-approved amount. Plan G covers these excess charges. Plan N does not. If you live in a state where doctors frequently charge more (like New York), Plan N could end up costing you more in the long run.
Actionable Steps for Your Next Move
Don't just sign up because you like the logo. Do these three things first:
- Check your doctors: Call your main specialists and ask, "Do you accept Original Medicare?" If they say yes, aarp supplemental health insurance united healthcare will work there.
- Compare the "Extra" value: Look at the cost of your current gym membership. If the UHC plan includes a free gym membership via Renew Active, subtract that monthly cost from the insurance premium to see the "true" price.
- Confirm your window: Are you in your 6-month Open Enrollment window? If yes, move fast. This is your one "get out of jail free" card to get the best rates without a physical.
- Download the 2026 Guide: Go to the UnitedHealthcare website and grab the specific "Outline of Coverage" for your ZIP code. It will list the exact monthly premium for every plan letter available to you.
Insurance isn't about finding the "best" plan; it's about finding the one that makes your monthly budget predictable so a surprise hospital stay doesn't wreck your retirement.
