Medicare Enrollment in Connecticut: Deadlines, Penalties, and How to Avoid Costly Mistakes

Medicare is one of the most important financial decisions you'll make as you approach 65 — and one of the most confusing. Miss the wrong deadline and you could pay higher premiums for the rest of your life. Here's what every Connecticut resident needs to know.

You're eligible for Medicare at age 65. But eligibility and enrollment are two different things — you have to actively sign up.

Your Initial Enrollment Period is a 7-month window:

• 3 months before your 65th birthday month
• Your birthday month
• 3 months after your birthday month

Pro tip: Enroll in the 3 months before your birthday month to ensure coverage starts on the first day of your birthday month. Enrolling during or after your birthday month delays your start date.

If you don't have other qualifying coverage (like employer insurance) and miss your IEP, you'll face late enrollment penalties that last for life:

• Part B penalty: 10% added to your monthly premium for every 12-month period you were eligible but didn't enroll. On a $185/month premium, that adds up fast.
• Part D penalty: 1% of the national base premium for every month you went without creditable drug coverage.

These penalties don't go away. They follow you for as long as you have Medicare.

If you're covered by employer insurance (yours or a spouse's) when you turn 65, you can delay Medicare without penalty. You'll get a Special Enrollment Period that lasts 8 months after your employment or employer coverage ends — whichever comes first.

Important: COBRA and retiree coverage do NOT count as employer coverage for SEP purposes. If you're on COBRA at 65, enroll in Medicare during your IEP.

Once you're enrolled in Medicare, you have choices about how you receive your benefits.

The federal program. Part A covers hospital stays; Part B covers outpatient care, doctor visits, and preventive services. You can see any doctor who accepts Medicare — nationwide.

The gap: Original Medicare covers about 80% of approved costs. You're responsible for the remaining 20% with no out-of-pocket maximum.

A private insurance policy that fills the gaps Original Medicare leaves. Depending on the plan, it can cover your 20% coinsurance, hospital deductibles, and even foreign travel emergencies. You keep your Original Medicare and use it anywhere in the country.

Best for: People who want predictable costs, travel frequently, or want maximum provider flexibility.

An alternative to Original Medicare offered by private insurers. Bundles Parts A and B (and usually Part D) into one plan. Often includes extra benefits like dental, vision, and hearing. Typically has lower premiums but uses provider networks.

Best for: People who prefer a managed care approach, want extra benefits, and are comfortable staying in-network.

Connecticut has strong consumer protections for Medicare Supplement plans:

• Connecticut is one of a handful of states with guaranteed issue protections that go beyond federal law, making it easier to switch Medigap plans in certain situations.
• Connecticut residents have access to the Connecticut State Health Insurance Assistance Program (SHIP) — free, unbiased Medicare counseling.

Every year from October 15 to December 7, you can:

• Switch from Original Medicare to Medicare Advantage (or back)
• Change Medicare Advantage plans
• Join, switch, or drop a Part D drug plan

Changes take effect January 1 of the following year.
