Medicare can be confusing, but the right Medicare Supplement plan makes a big difference. Aetna, one of the best-known names in health insurance, offers Medicare Supplement plans that help fill the gaps in Original Medicare.
Plan G and Plan N are Aetna’s most popular choices thanks to their strong coverage and competitive premiums. But which one fits your needs?
Below we cover Aetna’s Medicare Supplement Plans G and N, compare their benefits, and share tips to help you choose among Medicare Supplement Plans for 2027.
Important Keys:
- Aetna offers several Medicare Supplement plans, which vary by state, with Plan G and Plan N being the most popular.
- Medigap benefits are standardized by federal law and cover costs like hospital coinsurance, Part B coinsurance and, depending on the plan, deductibles. Medigap does not cover prescription drugs.
- When choosing an Aetna plan, match the coverage to your healthcare needs and compare premiums across companies. We can help.
Why Choose an Aetna Medicare Supplement?
Aetna is a leading provider of Medicare Supplement plans, which are standardized plans sold by private insurance companies, so the coverage is identical no matter which company you choose.
Unlike Medicare Advantage plans, Medicare Supplement plans let you see any doctor, specialist or hospital in the country that accepts Medicare, giving you more freedom to choose your providers.
And unlike Medicare Advantage plans, Medigap plans do not add their own prior authorization or referral requirements.
Aetna Medigap Plan Options
There are ten standardized Medicare Supplement plans. Aetna’s lineup varies by state and may include Plan A, Plan B, Plan F (only if you were eligible for Medicare before 2020), Plan G, high-deductible Plan G and Plan N. Plan G and Plan N are the most popular because of their strong coverage and competitive premiums.
Plan G covers more than Plan N but has a higher premium. Plan F covers everything, including both Medicare deductibles, but it is only available to people eligible for Medicare before January 1, 2020. See every plan side by side on our Medicare Supplement plans comparison chart for 2027.
Medigap Standardized Benefits
Aetna’s Medicare Supplement plans follow the standardized benefits set by federal law, so each plan letter offers the same benefits no matter which company sells it. Massachusetts, Minnesota and Wisconsin use their own standardized plans.
Depending on the plan, Medigap covers costs such as the Part A deductible, hospital and skilled nursing coinsurance, Part B coinsurance and excess charges. It does not cover prescription drugs, routine dental, vision or hearing care, or long-term care.
That means you get consistent coverage within each plan letter, whichever company you choose.
Aetna Medicare Plan G – The Top Plan?
Medicare Plan G is often considered the top Aetna Medicare Supplement plan for people new to Medicare. It covers your share of Medicare-approved costs except the annual Part B deductible, which is $283 in 2026. Medicare announces the 2027 amount later in the fall.
Once you meet the Part B deductible, Plan G covers 100% of your remaining Medicare-approved costs for the year.
That complete coverage comes with a higher premium than plans like Plan N. Premiums vary widely by age, location and company.
Medigap Plan G Coverage
Aetna Medicare Supplement Plan G helps pay the costs Medicare Part A and Part B leave behind. In other words, it picks up where Original Medicare coverage ends.
Plan G covers the Part A deductible, hospital and skilled nursing coinsurance, Part B coinsurance, Part B excess charges, the first three pints of blood and 80% of foreign travel emergency care.
Plan G does not cover the Part B annual deductible, so you pay the first $283 (2026 amount) of Part B costs each year before Plan G starts paying.
For most people that trade-off is well worth it, because Plan G’s premium is usually much lower than Plan F’s for nearly the same coverage.
Medicare Supplement Plan G Rates
Aetna’s Plan G premiums depend on your age, ZIP code, gender, tobacco use and any household discount.

Weigh Plan G’s comprehensive coverage against the out-of-pocket costs of lesser plans. The right choice comes down to your healthcare needs and budget.
Aetna Medicare Plan N – Rising in Popularity
Aetna Medicare Plan N is another popular choice, especially for people who want a lower premium without giving up much coverage.
Medicare Supplement Plan N has some small out-of-pocket costs: copays of up to $20 for some office visits and up to $50 for ER visits that do not end in admission. It still covers most healthcare costs.
The other trade-off is Part B excess charges, which some doctors who do not accept Medicare assignment can bill, up to 15% above the Medicare-approved amount.
The vast majority of doctors accept Medicare assignment and do not charge Medicare Part B excess charges, so for most people this rarely comes up.
What Does Aetna Medicare Plan N Cover?
Aetna Plan N covers the Medicare Part A deductible, hospital and skilled nursing coinsurance, Part B coinsurance (except the small copays), the first three pints of blood and 80% of foreign travel emergency care.
Plan N gives you a strong safety net with a lower premium than more comprehensive plans.
Plan N does not cover the Medicare Part B deductible, Part B excess charges, or the copays for some office and ER visits.
Factor these small costs in when comparing Plan N with Plan G.
Aetna Medigap Plan N Rates
Plan N premiums are usually lower than Plan G or Plan F premiums.
That makes Plan N a good balance between coverage and affordability.
Depending on your age and location, the premium savings with Plan N are often enough to cover several doctor copays a year.
For many people, that savings plus solid coverage makes Plan N an appealing choice.
Aetna Medicare Plan G vs Plan N
Choosing between Aetna Plan G and Plan N comes down to coverage differences and premium cost.
Each plan has advantages, and the right choice depends on your situation.
Here is how they compare.
Coverage Differences
The main differences between Plan G and Plan N are Part B excess charges and copays for some office and emergency room visits.
Plan G covers Part B excess charges, so you will not get surprise bills from doctors who charge above Medicare rates. Plan N does not cover excess charges.
Plan N also has copays of up to $20 for some office visits and up to $50 for ER visits that do not end in admission. Plan G has no copays.
These copays are small, but they can add up if you see the doctor often.
Premium Considerations
Plan G usually has a higher premium than Plan N because it covers more.
The price difference depends on your age, location and the company.
When comparing premiums, weigh Plan G’s extra coverage against Plan N’s savings.
The right balance depends on your healthcare needs and budget.
Aetna has competitive rates in many areas and offers a household discount in many states. Other competitive companies include Mutual of Omaha, Allstate, Manhattan Life and many more.

Is Aetna Medicare Supplement Plan F Worth Considering?
Aetna Plan F was long a popular choice for its complete coverage, but under federal law it is no longer sold to anyone who became eligible for Medicare on or after January 1, 2020.
If you are still eligible for Plan F, weigh its complete coverage against its higher premiums, which often rise faster because the plan is closed to new enrollees.
Many people choose Plan G instead. It covers everything Plan F does except the Part B deductible.
By paying the Part B deductible yourself ($283 in 2026), you can often save more in premiums than the deductible costs.
Medicare Enrollment Periods
The best time to buy an Aetna Medicare Supplement plan is your 6-month Medigap Open Enrollment Period. It starts the first day of the month you are both 65 or older and enrolled in Medicare Part B, and lasts six months.
During this window you can buy any plan regardless of your health, with no medical questions.
If you are over 65 and still have employer coverage, you may delay Part B. Your Medigap Open Enrollment Period then starts when you enroll in Part B, so you keep this protection for later. If your Medicare Advantage plan ends, you may also have a guaranteed issue right.
Guaranteed Renewability
Aetna’s Medicare Supplement plans are guaranteed renewable, which means your policy stays in effect as long as you pay your premium on time.
Aetna cannot cancel your coverage because of changes in your health or age.
That peace of mind matters when you are managing your healthcare for the long term.
Losing Your Medicare Advantage Plan in 2027?
If your Medicare Advantage plan is leaving Medicare or stops serving your area, federal law generally gives you a guaranteed issue right to buy certain Medigap plans, which for most people include Plan G, without medical underwriting. The right generally ends 63 days after your Medicare Advantage coverage ends.
Tips for Choosing an Aetna Medicare Supplement Plan
Several factors go into choosing the right Aetna Medicare Supplement plan.
Here is how to assess your needs and compare premiums.
Assessing Healthcare Needs
Think about your current and future medical needs, how often you see doctors, and any ongoing conditions.
Remember that Medigap does not cover prescription drugs, routine dental, vision or hearing care, so plan for those separately with a Part D plan and other coverage.
Then choose the Aetna plan whose coverage matches how you use care.
Comparing Premiums
When comparing Aetna premiums, consider your age, location, gender, tobacco use, household discounts, how you pay and the company’s rate increase history.
Those factors show which plan gives you the most value for your budget.
Choosing the right plan means balancing coverage and cost, so weigh your options carefully.
