Navigate Medicare enrollment, costs, and coverage decisions with a clearer view of the trade-offs. This comprehensive guide helps Connecticut retirees make informed healthcare choices that align with their retirement income strategy.
Understanding Medicare Basics
Medicare provides health insurance for Americans aged 65 and older, along with certain younger individuals with disabilities. According to the Centers for Medicare & Medicaid Services, approximately 65 million Americans are enrolled in Medicare as of 2026. For Connecticut retirees, understanding the four parts of Medicare is essential for making informed coverage decisions.
Part A
Hospital insurance covering inpatient hospital stays, skilled nursing facility care, hospice care, and some home health care.
Part B
Medical insurance covering doctor visits, outpatient care, medical supplies, and preventive services.
Part C
Medicare Advantage plans offered by private companies as an alternative to Original Medicare, often including prescription drug coverage.
Part D
Prescription drug coverage available through standalone plans or included in Medicare Advantage plans.
Critical Enrollment Deadlines
Missing Medicare enrollment deadlines can result in permanent penalties and delayed coverage. Connecticut retirees should be aware of these key timeframes to avoid costly mistakes.
Initial Enrollment Period (IEP)
Seven-month window starting three months before your 65th birthday month, including your birthday month, and continuing for three months after. This is typically your first opportunity to enroll in Medicare without penalties.
General Enrollment Period
January 1 through March 31 each year for those who missed their IEP. Coverage begins July 1, and late enrollment penalties may apply. The Part B penalty is 10% for each 12-month period you were eligible but not enrolled.
Annual Open Enrollment
October 15 through December 7 each year to change Medicare Advantage plans, switch between Original Medicare and Medicare Advantage, or change Part D prescription drug plans. Changes take effect January 1.
Special Enrollment Periods
Available for qualifying life events such as moving, losing employer coverage, or qualifying for Medicare due to disability. These periods allow enrollment outside standard timeframes without penalties.
Medicare Costs for 2026
Medicare costs vary based on income and coverage choices. Understanding these expenses helps Connecticut retirees budget accurately for healthcare in retirement. High-income earners face additional surcharges known as Income-Related Monthly Adjustment Amounts (IRMAA).
For 2026, Medicare Part B premiums are based on modified adjusted gross income from two years prior. Individuals earning over $103,000 or married couples earning over $206,000 pay higher premiums. The highest earners can pay over $500 monthly for Part B coverage alone.
Medigap Insurance Options
Medigap policies help cover costs that Original Medicare doesn't pay, such as copayments, coinsurance, and deductibles. Connecticut offers guaranteed issue rights for Medigap policies, providing consumer protections beyond federal requirements.
Plan G
Most comprehensive coverage available to new Medicare beneficiaries. Covers all Medicare-approved expenses except the Part B deductible. Popular choice for comprehensive protection.
Plan N
Lower premium alternative with modest copayments for doctor visits and emergency room visits. Good option for healthy individuals seeking cost savings.
High-Deductible Plan G
Lower monthly premiums with higher out-of-pocket costs until the deductible is met. The 2026 deductible is $2,800. Suitable for those comfortable with higher initial costs.
Common Medicare Planning Mistakes
Avoiding these common pitfalls may help Connecticut retirees reduce unnecessary costs and coverage gaps that could impact their healthcare and retirement income strategy.

Worked Example
A conversion resized to stay under the surcharge
Hypothetical example — not an actual client.
An Avon couple on Medicare plans a $15,000 Roth conversion that would lift income above the first Medicare surcharge threshold of $218,000. Resizing the conversion to $5,000 keeps them under it and avoids about $2,296 a year in premium surcharges — a cost that would not appear until 2 years later.
The household
George and Lisa Martin, ages 70 and 68, live in Avon. Both are enrolled in Medicare. Neither has reached required-distribution age, so conversions are still discretionary.
The problem
Medicare premiums are income-tested, and the test looks back 2 years. Ordinary brackets are steps — only income above the line is taxed at the higher rate. The Medicare surcharge is not a step. One dollar over the threshold applies the full surcharge for that tier, to both spouses, for a full year. A $15,000 conversion would take this couple from $210,000 to $225,000, past the line.
The strategy
- Resize the current-year conversion from $15,000 to $5,000, holding income at $215,000 — $3,000 below the threshold rather than exactly on it, so a late 1099 correction or a year-end fund distribution cannot trip the cliff.
- Defer the remaining $10,000 to a year with more room under the line.
- Weigh the surcharge against the conversion rather than avoiding it reflexively. A large enough conversion can be worth paying a surcharge tier to complete.
The arithmetic
- Projected income before conversion
- $210,000
- With the full conversion
- $225,000over the $218,000 threshold
- With the resized conversion
- $215,000$3,000 of headroom
- First-tier surcharge per person
- $1,148/yrtwo enrolled spouses
What it accomplishes
By resizing one conversion, George and Lisa avoid roughly $2,296 a year of Medicare surcharges — and they do it with margin to spare rather than by landing on the threshold. The remaining $10,000 of conversion capacity is not lost; it moves to a year with room.
Where this breaks down
- Surcharge tiers and premium amounts change annually. Figures reflect the 2026 tax year and must be re-checked before each conversion decision.
- Thresholds behave as cliffs, but appeals are available after life-changing events such as retirement or the death of a spouse. A household that crosses a threshold is not automatically stuck with the result.
- A conversion may still be worth doing after accounting for a surcharge. This illustration shows the trade-off being measured, not a rule that surcharges must always be avoided.

Federal and Connecticut thresholds change, and Connecticut’s are set by budget act rather than indexed to inflation.
