Connecticut gives Medicare Supplement (Medigap) buyers a protection most states don't: you can buy or switch a policy any time of year, with no medical underwriting. Connecticut is one of a few states (New York is another) that require Medigap coverage to be sold on a guaranteed-issue basis year-round and priced by community rating, so your age, gender, and health cannot change what you pay. This guide explains how Connecticut's year-round guaranteed-issue and community-rating rules work, how the standardized A-through-N plans fit together, which plans are closed to newer enrollees, and who regulates Medigap in the state.
How Medigap works in Connecticut
A Medigap policy is private insurance that pays the deductibles and coinsurance Original Medicare leaves to you. Medigap (Medicare Supplement Insurance) works only alongside Original Medicare, not with a Medicare Advantage plan, and each policy covers one person. A married couple who both want coverage need two policies.
Connecticut uses the federal standardized framework. Medigap is sold as lettered plans, A through N, and the benefits inside each letter are fixed by federal rule. A Plan G from one Connecticut insurer covers exactly what a Plan G from another covers. Insurers compete on price, service, and rate stability, not on what the plan pays. That makes the plan letter your first decision and the insurer your second.
The gaps Medigap closes are real. After the Part B deductible ($283 in 2026), Original Medicare pays 80% of the approved amount for most outpatient care and leaves you the other 20%, with no annual cap. Part A adds a hospital deductible of $1,736 per benefit period in 2026, and that deductible can apply more than once in a year. Medigap caps that exposure.
Connecticut's year-round guaranteed issue and community rating
Connecticut's standout protection is that Medigap is available on a guaranteed-issue basis at all times. Under Connecticut law, an insurer must sell a standardized Medigap policy to any eligible Medicare enrollee at any time of year, without medical underwriting, and rates may not vary based on an applicant's age, gender, or health status, according to the Connecticut Insurance Department. The age-blind, health-blind pricing rule is called community rating.
The practical value is large. In most states, the best time to buy Medigap is a one-time, six-month window at age 65, and switching later can require you to pass medical underwriting. In Connecticut, that pressure is removed: you can shop and switch carriers whenever you like, and a new diagnosis cannot be used to deny you or raise your rate. Because pricing is community-rated, two 80-year-olds and two 65-year-olds pay the same premium for the same plan from the same insurer.
There is one limit to know. A pre-existing condition limitation can apply if you enroll without prior creditable coverage or after a gap in coverage. If you move from one form of coverage to a Medigap policy without a break, that limitation generally does not apply. The guaranteed-issue right itself, however, does not depend on your health.
How to buy or switch in Connecticut
Because there is no annual window to wait for, the steps are simple, but the order still matters.
- Pick your plan letter first. Decide which standardized plan (most often Plan G or Plan N) fits your budget and how much cost-sharing you want to carry.
- Compare community-rated premiums. Benefits inside a letter are identical across insurers, so compare price, service, and the carrier's history of rate increases. In a community-rated state, you are comparing one premium per insurer, not an age-banded quote.
- Apply any time. You do not need to wait for a birthday or a special period. Tell the insurer you are buying or switching under Connecticut's guaranteed-issue rules.
- Keep the old policy until the new one starts. Don't cancel existing coverage until the new policy is confirmed and in force, so you're never uninsured, and so no pre-existing condition limitation can attach from a gap.
Because the benefits inside a letter are standardized, a switch at the same letter changes your premium and insurer, not your coverage.
Plan G and Plan N: the common choices
For someone newly eligible for Medicare, the practical choice in Connecticut narrows to two plans.
Plan G is the most complete plan still available to people who became eligible on or after January 1, 2020. It covers every gap in Original Medicare except the annual Part B deductible: the Part A hospital deductible, Part A and Part B coinsurance, skilled nursing facility coinsurance, and Part B excess charges. After you pay that one Part B deductible for the year, a Plan G holder generally has no further cost-sharing on Medicare-covered services.
Plan N covers the same major gaps but shifts a little cost back to you. It pays the Part B coinsurance except for a copay of up to $20 for some office visits and up to $50 for emergency-room visits that don't lead to an inpatient admission, and it does not cover Part B excess charges. In exchange, Plan N premiums are usually lower than Plan G premiums.
Connecticut also offers a high-deductible version of Plan F and Plan G. With the high-deductible option, you pay covered costs yourself until you meet a plan deductible of $2,950 in 2026, after which the policy pays. The trade is a much lower monthly premium in exchange for more out-of-pocket risk before coverage kicks in.
| Feature | Plan G | Plan N |
|---|---|---|
| Part A hospital deductible | Covered | Covered |
| Part B coinsurance | Covered in full | Covered, minus up to $20 office / $50 ER copays |
| Part B excess charges | Covered | Not covered |
| Annual Part B deductible ($283 in 2026) | You pay it | You pay it |
| Skilled nursing facility coinsurance | Covered | Covered |
| Relative premium | Higher | Lower than Plan G |
Plans C and F are closed to newer enrollees
Plans C and F once covered the annual Part B deductible on top of the other gaps, which made Plan F the most complete plan on the market. Under the Medicare Access and CHIP Reauthorization Act of 2015 (MACRA), any Medigap plan that pays the Part B deductible is closed to people who first became eligible for Medicare on or after January 1, 2020.
The closure works by eligibility date, not purchase date. If you became eligible for Medicare before January 1, 2020, you can still buy or keep Plan C or Plan F in Connecticut, including the high-deductible Plan F. If you became eligible on or after that date, those two plans are off the table, which is why Plan G has become the default top-tier choice for newer enrollees: it's identical to Plan F except that you pay the one Part B deductible yourself.
The federal six-month open enrollment still applies
Connecticut's year-round guaranteed issue sits on top of the federal Medigap rules, which still apply.
- The federal Medigap Open Enrollment Period. This is a one-time, six-month window that begins the first month you're both age 65 or older and enrolled in Medicare Part B. During it, insurers nationwide must sell you any Medigap policy they offer at their best available rate regardless of your health.
- Connecticut's year-round guaranteed issue. Beyond the federal window, Connecticut keeps the door open for life: you can buy or switch any time, with no underwriting and community-rated pricing.
- Federal guaranteed-issue rights. Certain life events, such as losing other coverage or an insurer leaving the market, trigger a federal guaranteed-issue right to buy specific plans without underwriting.
In most states the federal six-month window is the one moment health cannot be used against you. In Connecticut, that protection effectively continues indefinitely, so the choice between Plan G and Plan N is less of a one-shot decision than it is elsewhere.
What Medigap costs and how it's priced in Connecticut
Medigap premiums vary by plan and insurer. Nationally, median Plan G premiums run about $150 to $175 a month and Plan N about $125 to $150, though your Connecticut quote can fall outside those ranges. Note that Medigap does not include prescription drug coverage, so you add a separate Part D plan for that.
Connecticut's community-rating rule shapes pricing differently from most states. Elsewhere, insurers use issue-age or attained-age methods, so a low first-year quote can climb as you get older. In Connecticut, premiums cannot be set or raised based on your individual age, gender, or health, so an 80-year-old and a 70-year-old generally pay the same rate for the same plan from the same carrier. Premiums can still rise over time for everyone in a plan, which is why comparing each insurer's rate-increase history matters even in a community-rated state.

Frequently asked questions
Yes. Connecticut requires Medigap to be sold on a guaranteed-issue basis year-round, so you can buy or switch a standardized policy at any time, with no medical underwriting. A pre-existing condition limitation may apply only if you have no prior creditable coverage or have had a gap in coverage, per the Connecticut Insurance Department.
Community rating means your premium cannot vary based on your age, gender, or health status. Everyone in the same plan from the same insurer pays the same rate, so a 65-year-old and an 80-year-old are charged alike. Premiums can still rise over time for everyone in a plan.
No. Connecticut is one of a few states with these protections, and New York has similar guaranteed-issue and community-rating rules. Most states do not require year-round guaranteed issue.
Only if you first became eligible for Medicare before January 1, 2020. Plans C and F, which cover the Part B deductible, are closed to anyone who became eligible on or after that date under MACRA. Plan G is the closest available alternative; it's identical to Plan F except that you pay the annual Part B deductible yourself.
