Understanding when Connecticut insurers can deny, charge more, or impose waiting periods for Medicare Supplement (Medigap) coverage.
Last updated: January 2026 | Written by licensed CT insurance professionals
The Short Answer
During your 6-month Medigap Open Enrollment Period, Connecticut insurers cannot deny you coverage. Outside this window, insurers can use medical underwriting and may deny applications based on health conditions. Your enrollment timing is critical to guaranteeing coverage.
Key Points About Medigap Denial in Connecticut
During Open Enrollment
Insurers MUST accept you regardless of health conditions. No denial, no higher premiums, no waiting periods.
Outside Open Enrollment
Insurers CAN deny you, charge higher premiums, or exclude pre-existing conditions based on your health history.
The 6-Month Window
Your Medigap Open Enrollment begins the first day of the month you’re both 65+ AND enrolled in Part B.
Special Guaranteed Issue
Certain life events (losing coverage, plan leaving area) trigger guaranteed issue rights outside open enrollment.
When You Have Guaranteed Issue Rights
These situations give you the right to buy Medigap without health questions
