15 Key Facts About AARP Medicare Supplement Plan F (2026)

Key Takeaways

• Plan F is only available to people who became Medicare-eligible before January 1, 2020; newer enrollees should compare Plan G instead, which covers nearly identical benefits except the Part B deductible.
• Plan F covers cost-sharing for Medicare-approved primary care and preventive services with potentially $0 member costs, but does not cover prescriptions, dental, vision, hearing, or services Medicare excludes.
• Premiums vary by insurer, location, age, and rating method and are paid separately from Part B premiums; lower-premium plans may cost less annually if you use fewer services despite Plan F's broader coverage.
• You can use any Medicare-accepting provider nationwide with no network restrictions or referral requirements, giving you flexibility in choosing primary care doctors and specialists.

Choosing how to pay for health care after 65 can feel confusing. Many people want one simple thing: to know what they will owe when they visit their doctor. That is why AARP Medicare Supplement Plan F still draws so much attention in 2026.

Plan F is a Medigap policy sold by UnitedHealthcare under the AARP brand in many areas. It helps pay costs that Original Medicare leaves behind, such as deductibles and coinsurance. For people who use primary care, annual wellness visits, and preventive screenings often, that can mean steadier costs.

But Plan F is not for everyone. It has strict enrollment rules, it does not cover prescriptions, and its premiums vary. This guide gives you 15 clear facts so you can decide with confidence. We also explain how Plan F fits with the primary care and wellness services you use each year.

What AARP Medicare Supplement Plan F Actually Is

Start with the basics. These first facts explain what this plan is and what it is not.

1. It is Medigap, not Medicare Advantage

Medigap is private insurance that works alongside Original Medicare (Parts A and B). It does not replace Medicare. This is different from Medicare Advantage, which is a separate type of plan.

2. The AARP name goes with UnitedHealthcare

AARP Medicare Supplement plans are offered through UnitedHealthcare in many areas. The plan follows the same standard benefits as any Plan F in most states.

3. Plan F is the most complete standard Medigap option

Plan F generally pays the Part A and Part B deductibles and coinsurance for Medicare-approved services. It also covers Part B excess charges. That broad coverage is why many people call it the most comprehensive plan.

Who Can Still Enroll in Plan F in 2026

This is the question we hear most. The answer depends on when you became eligible for Medicare.

4. The cutoff date is January 1, 2020

Plan F and Plan C cover the Part B deductible. Because of that, they cannot be newly sold to people who first became eligible for Medicare on or after January 1, 2020 (Medicare.gov).

5. Some people who enroll later may still qualify

If you were eligible for Medicare before 2020, you may still qualify even if you enrolled later. State rules and your own situation can change this, so always confirm current availability.

6. Newer enrollees often look at Plan G

If you became eligible after 2019, Plan G is the closest option. Plan G covers nearly the same costs but does not pay the Part B deductible. Many people compare the two before choosing.

What Plan F Covers for Primary Care and Wellness

Primary care is where most people feel the value of a Medigap plan. These facts show how Plan F works in a doctor's office.

7. It helps with cost-sharing on covered primary care visits

After Medicare processes a covered claim, Plan F generally pays the cost-sharing that is left. Some 2026 AARP/UnitedHealthcare product pages list $0 member cost-sharing for covered primary care visits under the displayed Plan F option. That is subject to Medicare coverage rules and policy terms.

This does not mean every visit is free. Coverage depends on whether Medicare covers the service, whether your provider accepts Medicare, and whether the care is medically necessary.

8. Preventive services depend on Medicare rules

Medicare covers many screenings and the annual wellness visit under Part B when requirements are met. Plan F can pay the applicable cost-sharing, but it does not add new preventive services. If a visit includes a separate problem or a service Medicare does not cover, you may see a charge. You can learn more about what to expect in our guide on what happens during an annual wellness visit.

9. You can use any provider who accepts Medicare

Medigap works with Original Medicare. You can generally see any doctor nationwide who accepts Medicare. There is no network and no referral requirement for specialists. Still, it is smart to confirm that your doctor accepts Medicare before you book. If you need help finding a practice, see our tips on finding a doctor that accepts Medicare.

What Plan F Does Not Cover

A strong plan still has limits. Knowing them helps you avoid surprise bills.

10. No prescription drug coverage

Plan F does not include outpatient prescription drug benefits. Most people add a separate Medicare Part D plan. If you take regular medicines, plan for this cost. Our article on prescription management tips for 2026 can help you stay organized.

11. Dental, vision, and hearing are not standard

Routine dental, vision, and hearing care are not standard Plan F benefits. Many people buy stand-alone coverage for these needs.

12. It does not expand what Medicare covers

Medigap only pays costs for services that Medicare already approves. If Medicare does not cover a service, Plan F will not either. This matters for newer wellness services that fall outside Medicare, such as some advanced testing or elective treatments.

Understanding the Cost of Plan F

Price is often the deciding factor. These facts will help you compare fairly.

13. Premiums are separate from Part B and they vary

You pay your Plan F premium in addition to your Medicare Part B premium. Premiums depend on the insurer, your location, your age, the rating method, and other factors. They can also rise over time. A 2026 notice from the Chicago Teachers' Pension Fund reported AARP/UnitedHealthcare Plan F increases effective June 1, 2026. Those figures applied to that group only, so do not treat them as general market rates.

14. High-deductible Plan F is a different product

Medicare.gov's 2026 guidance lists a $2,950 annual deductible for high-deductible Plan F and Plan G options. You pay that amount before the policy begins to pay covered costs. This is not the same as standard Plan F.

15. Broad coverage does not always mean the lowest total cost

Plan F can give you very predictable costs. But a lower-premium plan may cost less over a full year if you use few services. Always compare current local quotes and the full policy terms.

How to Decide If Plan F Fits Your Health Needs

Use these steps to make a clear choice.

1. Confirm your eligibility. Check your Medicare start date against the January 1, 2020 cutoff.
2. List your yearly care. Count your primary care visits, specialist visits, screenings, and tests.
3. Request local quotes. Compare Plan F, Plan G, and other Medigap plans in your area.
4. Check your prescriptions. Choose a Part D plan that covers your medicines.
5. Review the policy certificate. Read state-specific terms, including foreign-travel limits.

One more point matters. The AARP/UnitedHealthcare page lists foreign-travel emergency coverage at 80% after a $250 annual deductible, with a $50,000 lifetime maximum. Verify these details in your own policy, since terms can differ by state.
