Understanding Medicare Supplement Plans in Connecticut

What Original Medicare Leaves You to Pay

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

Original Medicare Gap What It Means for You Covered By
Part A deductible Applied each hospital benefit period instead of annually. The 2026 amount was $1,736. Plans B, C, D, F, G and N fully; K, L and M partially
Part A hospital coinsurance Daily charges after day 60 of a hospital stay, which climb after day 90 All 10 plans, plus 365 extra hospital days
Part B deductible An annual deductible owed before Part B pays. In 2026, $283. Only Plans C and F
Part B coinsurance Typically 20% of the approved amount, with no annual cap All plans (K and L in part, N with copays)
Part B excess charges As much as 15% over the approved amount from doctors who do not accept assignment Plans F and G
Skilled nursing coinsurance Daily charges for days 21 through 100 of a covered stay Plans C, D, F, G, M and N (K and L in part)
Emergency care abroad Care outside the U.S. is generally not covered by Original Medicare. Plans C, D, F, G, M and N, up to plan limits

No limit unless you add a supplement: Original Medicare does not have an out-of-pocket maximum. If you lack a Medigap plan or other coverage, the 20% you may owe on Part B services has no ceiling.

*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.

What Drives Connecticut Medigap Prices

Your Age

Many insurers charge more as you get older.

Your ZIP Code

Prices vary by state and area.

Tobacco Use

Tobacco users usually pay more.

Discounts

Household or other discounts, which vary by insurer and state.

Pricing Method How the Premium Is Set Over Time
Community-rated All people in an area pay one premium, whatever their age Does not go up as you age, but may go up for inflation and other reasons
Issue-age-rated Based on your age when you buy Does not go up as you age, but may go up for other reasons
Attained-age-rated Based on your current age Rises as you age, on top of other increases

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.

Prices in Connecticut vary by ZIP code and insurer. Always quote your exact ZIP from several insurers.

Conclusion: Navigating Your Medicare Options Confidently

When You Can Buy

Key Takeaway

Your Medigap Open Enrollment Period lasts six months and begins the first month you are both 65 or older and enrolled in Part B. During this period, an insurer cannot turn you down or charge you more based on your health.

Be aware: once your six-month Medigap Open Enrollment Period has passed, and without a guaranteed issue right, insurers in most states may ask health questions and turn you down or charge you more.

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

You May Have a Right to Buy If

✔

Your Medicare Advantage plan exits your area or stops serving Medicare

✔

You enrolled in Medicare Advantage when you first became eligible at 65 and want to go back within the first year

✔

You left a Medigap policy to try Medicare Advantage for the first time and want to go back within a year

✔

Employer or union coverage that pays after Medicare stops

✔

Your Medigap insurer goes bankrupt or deceives you

Your state may give you extra rights: in New York and Connecticut you can enroll in Medigap at any time of year with no health questions, while states like California and Oregon offer an annual window to move to a plan that is equal or lesser.

Connecticut Medigap Rules

Connecticut rule: Connecticut lets people with Medicare buy or switch Medigap plans year-round without health questions under its guaranteed issue rules. Confirm current details with CHOICES before you apply.

What Medigap Does Not Cover

Not Covered by Medigap

✔

Prescription drugs: add a standalone Part D plan

✔

Routine dental care, hearing aids, and eye exams for glasses

✔

Long-term custodial care, whether in a nursing home or at home

✔

Private-duty nursing

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.

Medigap vs Medicare Advantage

Medicare Advantage Original Medicare + Medigap
Monthly premium Often low or $0 (2027 average $12, CMS) Higher; varies by plan letter, age and ZIP
Doctors Usually a network Any provider in the U.S. that accepts Medicare
Costs when you get care Copays and coinsurance up to a yearly maximum Low and predictable; on Plan G, little or nothing once the Part B deductible is met
Drug coverage Usually included Add a separate Part D plan
Dental, vision, hearing Many plans may include some coverage Not included
Changing later Every year during Annual Enrollment Health questions in most states once your Medigap Open Enrollment Period ends

Plans K and L: Lower Premiums With a Cost Cap

Rather than paying all of most costs, Plans K and L pay a portion: Plan K covers 50% and Plan L covers 75% of most cost sharing, leaving the remainder to you. In return for their lower premiums, both carry an annual out-of-pocket limit set by Medicare each year. After you hit that limit, the plan covers 100% of covered services for the remainder of the year.

These plans may fit people who want catastrophic protection for a lower premium and can manage some costs along the way. Check whether your insurer sells Plan K or L in your state.

Plans C and F for Earlier Enrollees

Only Plans C and F cover the Part B deductible. Since January 1, 2020, they have not been sold to people newly eligible for Medicare. If you became eligible for Medicare before that date, even without enrolling, you may still be able to purchase Plan C or F, including a High-Deductible Plan F that has the same $3,050 deductible for 2027.

For most people eligible to buy either, set the yearly premium gap between Plan F and Plan G against the Part B deductible. If the extra cost of Plan F exceeds what it saves you on the deductible, Plan G is the better value.

Medigap Under 65

If disability or end-stage renal disease gives you Medicare before 65, federal law does not make insurers sell you a Medigap policy, though many states require it. Prices for those under 65 can run much higher, and plan options may be limited. At 65, you get a fresh six-month Medigap Open Enrollment Period, during which you can buy any plan sold in your state at the same prices others your age pay.

Medigap When You Travel

Within the U.S., a Medigap plan goes wherever you go, since it works with any provider that accepts Medicare. Abroad, Original Medicare generally pays nothing, but Plans C, D, F, G, M and N pay 80% of emergency care outside the U.S. after a $250 annual deductible, up to a $50,000 lifetime limit.

Rate Increases and Switching Insurers Later

Once you buy Medigap, its benefits never change, but its premiums can. Insurers submit rate increases to state regulators, frequently once a year. Since the same plan letter has the same benefits everywhere, moving to a cheaper insurer can cut costs while your coverage stays the same.

The drawback is underwriting. Outside your Medigap Open Enrollment Period or a guaranteed issue situation, most states allow the new insurer to ask health questions and turn you down. Do not cancel your current policy until the new one has been approved and is in force.

How Medigap Claims Work

Usually you won’t ever file a Medigap claim. Your doctor sends the bill to Medicare, Medicare pays its portion, and the claim passes automatically to your Medigap insurer, which then pays its portion. A Medicare Summary Notice and an explanation of benefits show you what each one paid.

Medigap and Part D Together

Medigap plans sold now don’t include prescription coverage, so you should add a Part D plan as well. It doesn’t need to come from your Medigap insurer. Pick it based on your drugs and pharmacy in Medicare Plan Finder and look it over each fall. If you put off drug coverage with no other creditable coverage, the late penalty adds 1% of the national base beneficiary premium, $41.33 for 2027, for each month you were without it.

Turning 65 in 2027

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.

Turning 65 Checklist

✔

Enroll in Part A and Part B, unless you have qualifying employer coverage and decide to postpone Part B

✔

Choose between Medicare Advantage and Original Medicare plus Medigap

✔

Enroll in a drug plan, or a Medicare Advantage plan that includes drugs, to avoid a late Part D penalty

✔

If you go with Medigap, purchase during your six-month Medigap Open Enrollment Period

Help Paying Medicare Costs

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

Medicare Savings Programs

✔

Run by your state Medicaid office

✔

May cover your Part B premium, and in some cases deductibles and coinsurance

✔

Income and asset limits vary by state

Extra Help (Part D)

✔

Run by Social Security

✔

Lowers Part D premiums, deductibles and copays

✔

Those enrolled in a Medicare Savings Program qualify automatically

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.

Excess Charges and Medicare Assignment

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.

Your Medigap Open Enrollment Period in Detail

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.

Switching From Medicare Advantage to Medigap

Step by Step

1

See if you have a guaranteed issue right. One example is when your plan is ending or you are still in your first year of Medicare Advantage.

2

If you don’t, look up your state’s rules. A few states grant extra rights; most permit health questions.

3

Get your Medigap application in before leaving Medicare Advantage. Confirm your approval first.

4

Join a Part D plan. Medigap does not cover drugs.

5

Time your exit from Medicare Advantage correctly. Use Annual Enrollment or the window from January to March.

Medigap With Employer or Retiree Coverage

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 Policies

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.

A Hospital Stay With and Without Medigap

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.

Watch the benefit periods: you owe the Part A deductible for each benefit period rather than once per year. Without Medigap, two separate hospital stays can mean paying the deductible twice.

Pre-Existing Condition Waiting Periods

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.

The 30-Day Free Look Period

When you swap one Medigap policy for another, you generally have 30 days to decide if you want to keep the new one. During that period, pay both premiums, and hold off on canceling the old policy until you’re confident in the new one.

How to Read a Medigap Quote

Check Each Quote For

✔

Plan letter, so you compare like with like

✔

Monthly premium plus any first-year or enrollment discount

✔

Pricing method: community-rated, issue-age or attained-age

✔

Household or payment discounts applied

✔

Effective date and any application conditions

When a quote has an introductory discount, find out what the premium will be once it expires.

Common Medigap Mistakes

Avoid These

1

Letting your open enrollment period pass. After it ends, you may face health questions.

2

Picking on current price only. Pricing method and rate history count.

3

Forgetting Part D. The late penalty is permanent.

4

Switching from Medigap to Medicare Advantage with no way back planned. Returning could mean answering health questions.

5

Dropping a policy before the new one is approved. This could leave you with no coverage.

Medigap and Medicaid

With full Medicaid, you generally do not need Medigap, and insurers generally are not allowed to sell you a policy that duplicates Medicaid benefits. A Medicare Savings Program, if you qualify, may pay your Part B premium and sometimes deductibles and coinsurance; check whether a Medigap policy would still add value for you.

Bottom Line

The Bottom Line

For most people new to Medicare in Connecticut, the best Medigap plans for 2027 are Plan G, Plan N and High-Deductible Plan G. Compare Connecticut prices for your ZIP, buy during your Medigap Open Enrollment Period or a guaranteed issue window, and add a Part D plan.

Frequently Asked Questions

➤ What is the best Medigap plan in Connecticut?

For most people new to Medicare in Connecticut, Plan G, Plan N or High-Deductible Plan G is the strongest starting point. Because benefits within each letter are standardized, the smart move is comparing what each insurer charges for your ZIP code and how it prices the policy over time.

➤ When can I buy Medigap in Connecticut?

The ideal time is your six-month Medigap Open Enrollment Period, which begins the first month you are 65 or older and enrolled in Part B. Connecticut also gives residents guaranteed issue rights throughout the year, so you are not locked out later, though checking current state rules before you switch is wise.

➤ What is the 2027 High-Deductible Plan G deductible?

The High-Deductible Plan G deductible is $3,050 for 2027, an increase from $2,950 in 2026, according to CMS. Once you meet that amount, the policy pays like a standard Plan G, and the lower premium is the trade-off for carrying more of the upfront risk.

➤ Can I buy Medigap any time in Connecticut?

Yes. Connecticut is one of the few states with year-round guaranteed issue for Medigap, so insurers generally cannot turn you down because of your health when you apply. That makes it easier to leave Medicare Advantage or change Medigap plans, but premiums still differ by company.

➤ Where can I get free Medicare help in Connecticut?

CHOICES offers free, unbiased Medicare counseling to Connecticut residents. Its counselors can walk you through Medigap letters, Part D drug coverage and Medicare Advantage changes without selling you anything, which helps if you are weighing several options before 2027.

➤ Does Medigap cover prescriptions?

No. Medigap policies sold today do not include drug coverage, so Connecticut residents add a separate Part D plan. For 2027 the Part D deductible can be up to $700, and annual out-of-pocket drug costs are capped at $2,400.

➤ What happens if my HealthSpring Medicare Advantage plan in Connecticut is ending?

Your current coverage continues through December 31, 2026, and you qualify for a Special Enrollment Period to choose new coverage. You generally also gain a guaranteed issue right to buy certain Medigap plans, typically within 63 days after the plan ends, which pairs well with Connecticut’s year-round protections.

➤ Can I switch from Medicare Advantage to Medigap in Connecticut?

Yes. You can drop Medicare Advantage during Annual Enrollment, October 15 to December 7, 2026, and return to Original Medicare for January 1, 2027. With Connecticut’s guaranteed issue rules you can then apply for a Medigap policy and add a standalone Part D plan for prescriptions.
