Missing a health insurance enrollment deadline in Connecticut can leave you uninsured for months — and a single hospital visit during that gap can cost $25,000-$200,000. Yet 31% of Connecticut residents who became uninsured in 2025 mistakenly believed they had to wait until the next Open Enrollment Period. In reality, more than 25 different qualifying life events trigger a Special Enrollment Period (SEP) that lets you enroll year-round. Connecticut also offers year-round enrollment for Medicaid/HUSKY, Medicare Advantage Open Enrollment, and zero-cost CSR-eligible Marketplace coverage. This 2026 guide explains every enrollment window, every qualifying event, and exactly how to enroll without penalty.
2026 Open Enrollment Period Dates
Open Enrollment is the annual window during which anyone can enroll in or change a Marketplace plan without needing a qualifying life event. Connecticut’s Marketplace, Access Health CT, follows the federal calendar but offers a slightly extended deadline for January 1 coverage.
Connecticut 2026 Enrollment Calendar
| Enrollment Window | Start Date | End Date | Coverage Effective |
|---|---|---|---|
| Open Enrollment (Marketplace) | Nov 1, 2025 | Jan 15, 2026 | Jan 1 (enroll by Dec 15) or Feb 1 (enroll Dec 16-Jan 15) |
| Medicare Annual Election Period | Oct 15, 2025 | Dec 7, 2025 | Jan 1, 2026 |
| Medicare Advantage Open Enrollment | Jan 1, 2026 | Mar 31, 2026 | First of month following enrollment |
| Medicare General Enrollment (Part B) | Jan 1, 2026 | Mar 31, 2026 | First of month following enrollment |
| HUSKY (Medicaid/CHIP) | Year-round | No deadline | First of month following approval |
| Special Enrollment (Marketplace) | Year-round (with QLE) | 60 days from QLE | Typically first of month after enrollment |
| CSR-eligible (Marketplace, ≤150% FPL) | Year-round (CT special rule) | No deadline | First of month following enrollment |
| Employer Open Enrollment | Varies by employer | Typically 2-4 week window | First of plan year |
If you didn’t enroll by January 15, 2026, you are NOT locked out for the year. You can still enroll if: (1) you experienced a qualifying life event in the past 60 days, (2) your income is at or below 150% of the Federal Poverty Level ($22,590 individual / $46,800 family of 4 in 2026), (3) you qualify for HUSKY (Medicaid/CHIP), (4) you’re turning 65 and qualifying for Medicare, or (5) you’re a small business owner enrolling through Access Health CT for Small Business.
What Is a Special Enrollment Period?
A Special Enrollment Period (SEP) is a 60-day window triggered by a qualifying life event (QLE) during which you can enroll in or change Marketplace coverage outside Open Enrollment. SEPs prevent gaps in coverage caused by life changes. Most SEPs last 60 days from the date of the qualifying event — some begin 60 days BEFORE (e.g., loss of coverage anticipated). You must select a plan AND provide documentation within that window or wait for the next Open Enrollment.
Key Special Enrollment Period Rules in 2026
- 60-day window from date of qualifying event (most events)
- Coverage typically effective the 1st of the month following plan selection (some events trigger earlier effective dates)
- Document the qualifying event with required proof within 30 days of plan selection
- Failure to document cancels the SEP enrollment retroactively
- Can ONLY enroll in a metal tier matching your previous coverage in most cases (loss-of-coverage SEPs)
- New dependents (birth, adoption) get retroactive coverage to date of birth/adoption
- Marriage SEP allows newlyweds to enroll without limit on metal tier choice
- Some SEPs are ‘permanent’ — pregnancy, domestic violence survivors, etc.
Complete List of Qualifying Life Events
Federal regulations (45 CFR § 155.420) define qualifying events that trigger Special Enrollment Periods. Connecticut Access Health CT recognizes all federal QLEs plus several state-specific events. The list below covers all events recognized in Connecticut for 2026.
Loss of Health Coverage QLEs
- Loss of job-based coverage (involuntary termination, voluntary resignation, layoff, furlough)
- Loss of dependent coverage (turning 26, parent loses coverage)
- Loss of HUSKY/Medicaid (income too high, missed renewal — see unwinding SEPs below)
- Loss of Medicare (rare, e.g., disability ending and not yet 65)
- Loss of coverage through divorce, legal separation, or death of policyholder
- Loss of coverage through plan no longer offered (insurer exits market)
- Loss of grandfathered or grandmothered plan
- Loss of COBRA after end of maximum coverage period (18, 29, or 36 months)
- Loss of student health plan due to graduation
- Loss of TRICARE or VA health coverage
- Loss of subsidies due to income change (rare SEP)
Household Change QLEs
- Marriage (60-day SEP starts on wedding date)
- Domestic partnership (recognized in CT)
- Birth of a child (effective date of birth, retroactive coverage)
- Adoption, foster placement, or court-ordered child custody
- Divorce or legal separation (if loses coverage; no SEP if just gaining)
- Death of household member (if loses coverage)
- Pregnancy (Connecticut state SEP — federal does NOT recognize pregnancy as QLE)
Residence Change QLEs
- Permanent move to Connecticut from another state
- Permanent move within Connecticut that changes plan availability (between counties)
- Move from US territory to Connecticut
- Student moving to or from school (if moving across state lines)
- Seasonal worker moving to/from work location
- Release from incarceration (federal SEP)
- Move out of HMO/EPO service area
- Becoming US citizen, national, or lawful presence
Other Qualifying Events
- Marketplace error, misconduct, or technical issue caused enrollment problem
- Plan substantially violates contract (rare)
- AmeriCorps/VISTA/NCCC service beginning or ending
- Survivor of domestic abuse/spousal abandonment (special exception)
- Income now at or below 150% FPL (CSR-eligible year-round SEP, monthly)
- Tribal members (Indian Health Service users — special enrollment any time)
- End of bankruptcy stay affecting medical debt
- Court order requiring coverage (e.g., divorce decree)
Connecticut Access Health CT recognizes several SEPs broader than federal: (1) PREGNANCY triggers SEP in CT (federal does not), (2) CSR-eligible (≤150% FPL) can enroll any month year-round, (3) HUSKY ‘unwinding’ SEP through end of 2026 for residents losing Medicaid due to redetermination, (4) Loss of essential health benefits or dental/vision coverage in CT-regulated plans. ALWAYS apply if you think a QLE might apply — Access Health CT reviews case-by-case.
Documents Required to Prove Qualifying Events
Access Health CT requires documentation of qualifying events within 30 days of enrollment. Failure to submit proper documents results in retroactive cancellation of coverage — meaning any medical claims paid during that period become your responsibility. Always upload documentation through your Access Health CT account immediately after enrollment.
Required Documentation by QLE Type
- Loss of job-based coverage: Termination letter, COBRA notice (HIPAA certificate), or letter from former employer with end date
- Loss of HUSKY/Medicaid: Letter from DSS showing termination date and reason
- Loss of dependent coverage (turning 26): Letter from parent’s insurer or parent’s employer
- Loss through divorce: Divorce decree or legal separation order
- Marriage: Marriage certificate (state-issued, not religious only)
- Birth of child: Birth certificate or hospital birth record
- Adoption: Court adoption order or placement letter
- Permanent move: Lease, utility bill, mortgage statement, or government ID with new address
- Death of household member: Death certificate
- Pregnancy (CT only): Doctor or midwife letter confirming pregnancy and due date
- Income at or below 150% FPL: Recent tax return, W-2s, or 3 months pay stubs
- Loss of COBRA: COBRA termination letter from former plan administrator
- Citizenship/lawful presence: Naturalization certificate, green card, EAD card, visa
- Release from incarceration: Release paperwork from jail/prison
- Domestic abuse: Self-attestation form (no additional proof required)
Year-Round Enrollment for Low-Income Connecticut Residents
Since 2022, federal regulations (45 CFR § 155.420(d)(16)) have allowed Marketplaces to provide year-round Special Enrollment Periods for individuals and families with household incomes at or below 150% of the Federal Poverty Level. Connecticut Access Health CT adopted this rule and offers month-to-month enrollment for CSR-eligible residents. This is the most important enrollment expansion in a decade.
2026 Income Limits for Monthly Enrollment (150% FPL)
- Individual: $22,590 annual income
- Family of 2: $30,660 annual income
- Family of 3: $38,730 annual income
- Family of 4: $46,800 annual income
- Family of 5: $54,870 annual income
- Family of 6: $62,940 annual income
- Each additional person: +$8,070
Most CSR-eligible (≤150% FPL) Connecticut residents qualify for ZERO-premium Silver plans with enhanced cost-sharing reductions (CSR 94 — lowest deductibles and copays). For a single 35-year-old with $22,000 income in Hartford County: $0/month premium Silver plan with $0 deductible, $5 PCP visits, $15 specialist visits, and $2,000 out-of-pocket maximum. This continues throughout 2026 because of the extended Inflation Reduction Act ARPA enhanced subsidies.
Medicare Enrollment Periods in 2026
Medicare has its own enrollment windows separate from the ACA Marketplace. Missing certain Medicare deadlines can result in lifelong late enrollment penalties — Part B penalty is 10% of premium for each 12-month period you delayed; Part D penalty is 1% of national base premium per month delayed.
Medicare 2026 Enrollment Windows
- Initial Enrollment Period (IEP): 7-month window starting 3 months before turning 65
- Annual Election Period (AEP): Oct 15 – Dec 7, change MA or Part D for Jan 1 coverage
- Medicare Advantage Open Enrollment: Jan 1 – Mar 31, change MA plan once or return to Original Medicare + Part D
- General Enrollment Period (GEP): Jan 1 – Mar 31 for Part B if missed IEP
- Special Enrollment Periods: 8 months after job-based coverage ends, 2 months after MA plan ends, moving, dual-eligible, more
- Five-Star SEP: One change per year to a 5-star MA or Part D plan (Dec 8 – Nov 30)
- Medigap Open Enrollment: 6-month window starting first month enrolled in Part B at age 65+ — guaranteed issue
- Connecticut Birthday Rule (CGS § 38a-495a): Annual 30-day window after birthday to switch Medigap with no underwriting
Connecticut is one of only a few states with a ‘Birthday Rule’ allowing Medigap policyholders to switch to any equal or lesser benefit Medigap plan during a 30-day window starting on their birthday — WITHOUT medical underwriting. This is uniquely powerful: most states require full medical underwriting outside the initial Open Enrollment, often leading to denial for those with pre-existing conditions. CT Birthday Rule lets you shop for better pricing annually.
HUSKY (Medicaid/CHIP) Year-Round Enrollment
HUSKY Health — Connecticut’s Medicaid and Children’s Health Insurance Program — offers TRUE year-round enrollment with no waiting periods. Apply any day of the year through Access Health CT; eligibility is determined within 45 days (faster for pregnant women and infants); coverage typically effective the first of the month following approval.
2026 HUSKY Income Limits (Monthly)

| HUSKY D | Pregnant women | 263% FPL | $6,838 |
| MAGI-based Long-Term Services | Aged, disabled, LTC | $2,829/month income | Asset limit $1,600 |
Employer Health Plan Enrollment Windows
Employer group health plans typically have their own Open Enrollment window (usually 2-4 weeks in October-November) for January 1 plan year, plus 30-day enrollment windows for new hires and qualifying life events. ERISA Section 503 governs federal SEPs for employer plans; rules largely mirror Marketplace SEPs.
Employer Plan Enrollment Rules in 2026
- Annual Open Enrollment: typically Oct-Nov for Jan 1 plan year (employer choice)
- New hire enrollment: 30 days from start date (some employers allow 60 or 90 days)
- QLE enrollment: 30 days from qualifying event (some employers allow 60 days)
- HIPAA Special Enrollment: birth, adoption, marriage, loss of other coverage trigger 30-day SEP
- Section 125 Cafeteria Plan election changes: limited to QLEs during plan year
- Mid-year changes for HSA/FSA contribution: limited to QLE events
- COBRA election period: 60 days after qualifying event notice
- If employer adds dependents mid-year, dependents have 30-day enrollment
