Aflac Medicare Supplement Plan G

The 2027 Part B deductible is normally announced by CMS in November; in 2026 it was $283, and the Medicare Trustees project roughly $292 for 2027.

Original Medicare leaves gaps, and a Medicare Supplement plan is designed to fill them. It can pay these costs:

What each plan letter covers is set precisely by federal law, so a given letter carries identical benefits from every insurer in your state.

*Only people who became eligible for Medicare before January 1, 2020, can buy Plans C and F. **Plans K and L come with a yearly out-of-pocket limit that Medicare updates each year; once you hit it, the plan covers 100% of covered services for the remainder of the year. ***Plan N covers all Part B coinsurance apart from copays of up to $20 for certain office visits and up to $50 for ER visits that do not result in an inpatient admission. Massachusetts, Minnesota and Wisconsin use their own way of standardizing plans.

Aflac-branded Medicare Supplement plans are sold in some states, and availability varies, so confirm which company issues the policy where you live. Aflac is widely known for supplemental insurance, but for Medigap the only things that differ from other insurers are price, pricing method and service.

Most people new to Medicare choose one of these three. Plan G covers every gap except the Part B deductible. Plan N trades a lower premium for copays of up to $20 for some office visits and up to $50 for ER visits that do not lead to admission, and it does not cover Part B excess charges. High-Deductible Plan G has a $3,050 deductible for 2027, up from $2,950, then covers like Plan G. See Plan G vs Plan N.

Which method applies depends on the insurer and the state. Before buying, find out how a policy is priced, not only what it costs now.

In certain situations, federal law also grants guaranteed issue rights, generally within 63 days of other coverage ending:

In 2027, a standalone Part D plan can have a deductible of no more than $700 and an out-of-pocket cap of $2,400. Buy it with Medigap to avoid a late enrollment penalty that lasts for life.

When you turn 65 in 2027, you get a seven-month Initial Enrollment Period: the three months before your birthday month, the birthday month itself and the three months that follow. If you sign up in the first three months, coverage begins on the first day of your birthday month.

When your income and savings are limited, two programs can greatly lower your Medicare costs:

If you qualify for both Medicare and full Medicaid, you may also be able to join a Dual Special Needs Plan. See help for low-income Part D beneficiaries.

When a doctor “accepts assignment,” they agree to accept Medicare’s approved amount as payment in full. Doctors who don’t accept assignment may charge as much as 15% more, known as a Part B excess charge. Excess charges are covered by Plans F and G; Plan N and most other plans do not cover them.

Because most doctors accept assignment and some states restrict or ban excess charges, the risk is small for many people. Before deciding whether to pay for excess charge coverage, ask your doctors if they accept assignment.

You get a six-month Medigap Open Enrollment Period beginning in the first month you are both 65 or older and enrolled in Part B. It occurs only once and can’t be restarted. During this period, insurers have to sell you any Medigap plan they offer in your state at the same price healthy people pay.

If you work past 65, keep employer coverage and postpone Part B, your Medigap Open Enrollment Period does not begin until you sign up for Part B. Signing up for Part B early when you do not need it starts the clock and can waste this protection.

With coverage through a current employer, you may not need Medigap yet, and postponing Part B can save your Medigap Open Enrollment Period for later. Retiree coverage works differently: it can act like a supplement, so weigh it against Medigap before you give it up, since you may not be able to regain retiree coverage.

You generally have a guaranteed issue right to buy certain Medigap plans when employer or union coverage that pays after Medicare comes to an end.

Medicare SELECT, sold by some insurers, is a kind of Medigap that charges a lower premium in return for using certain hospitals, and sometimes doctors, for non-emergency care. Benefits are the same as the standard plan letter, but the network requirement makes these policies behave more like a managed plan. If freedom to see any doctor matters to you, pick a standard Medigap policy instead.

Take a hospital stay as an example. With no supplement, you owe the Part A deductible for each benefit period ($1,736 in 2026), plus 20% of the doctors’ Part B bills during your stay, with no limit. Plan G covers the Part A deductible and your Part B coinsurance; once the yearly Part B deductible is met, you generally owe nothing for Medicare-approved care.

When you purchase Medigap during your open enrollment period or under a guaranteed issue right, you generally cannot be turned down or charged extra because of health conditions. Even so, if you lacked creditable coverage beforehand, the insurer may apply a waiting period of up to six months before it pays for a pre-existing condition. Having had creditable coverage shortens or eliminates that wait.

You do not need to compare plans by yourself, and help should not cost you anything. Here are the free options:

Gather your Medicare card, a list of your drugs and doses, your doctors and your preferred pharmacies before you call. That way a long conversation becomes a quick one.
