Bridging the Health-Coverage Gap for Early Long Island Retirees Before Medicare

Most people planning an early retirement have already run the numbers on savings, Social Security, and maybe a pension. What they often haven’t run the numbers on is health insurance before Medicare.

For most people, Medicare coverage starts at 65. That means if you retire at 60 or 64 and a half, you’re on your own for coverage until your 65th birthday arrives. For some Long Islanders, that gap is a few months. For others, it’s five years or more. Either way, it’s not something to figure out after you’ve already given notice — it’s a strategy you should have in place before you make your exit from the workforce.

As you build that strategy, it’s important to know the options available to help you bridge any healthcare gaps and ensure you have the coverage you need without paying more than you should. 

Option 1: The Health Insurance Marketplace

The Health Insurance Marketplace is a common bridge for Long Islanders retiring before 65, and with good reason. These are full, regulated health plans, priced based on your income rather than your medical history.

Timing matters here more than almost anywhere else in this process. In most states, open enrollment runs from November 1st through January 15th. If you enroll by December 15th, coverage will start on January 1st. If you sign up by January 15th, your coverage will begin on February 1st. Outside that window, the Marketplace is closed to most people.

The good news: Retiring outside open enrollment doesn’t leave you stranded. Losing job-based coverage triggers a Special Enrollment Period, which gives you a 60-day window to enroll in a Marketplace plan.

Sixty days may sound like plenty of time. However, once you factor in choosing a plan, comparing networks, and making sure your doctors are covered, sixty days can pass quickly. If you miss the window, you’re not just late; you’re typically locked out of the Marketplace entirely until the next open enrollment period. Depending on when you retire, that could mean going without coverage for months.

Option 2: The COBRA Option

COBRA lets you keep the exact plan you had at work: same doctors, same network, same coverage, which generally lasts for up to 18 months after you leave your job. For some retirees, that continuity is worth a lot. No new insurance cards, no re-verifying which specialists are in network, no surprises about what’s covered.

The tradeoff shows up on the premium. Under COBRA, you pay the full cost of the plan yourself: the portion your employer used to cover, plus your own share, plus an additional 2% administrative fee. Most employees have no idea how much of their health plan their employer was actually paying for until that bill arrives in full.

That makes COBRA vs Marketplace one of the most important comparisons to run before you retire, not after. A Marketplace plan priced against your post-retirement income can come in dramatically lower, especially if a premium tax credit applies. COBRA rarely wins on cost alone. Instead, it wins on familiarity, and for some retirees who are mid-treatment for a specific condition or working with a specialist they don’t want to lose, that familiarity is worth paying for.

It’s important to note that the COBRA election runs 60 days from the date your coverage ends or the date you receive your COBRA election notice, whichever comes later. Use that time to actually compare the numbers side by side rather than defaulting to COBRA because it feels like the path of least resistance.

Option 3: Spouse’s Plan, Part-Time Work, or Medicaid

COBRA and the Marketplace aren’t the only bridges available. For some Long Islanders, they’re not even the best ones.

If your spouse is still working and carries employer coverage, adding yourself to their plan during their next open enrollment, or during a special enrollment triggered by your own job loss, may be the simplest and cheapest option on the table. No new deductible to satisfy, no new network to learn, and often a lower cost than anything COBRA or the Marketplace can offer.

Part-time or consulting work is worth consideration as well. Some employers offer group coverage to part-time staff at 20 to 30 hours a week. Many retirees who step away from a full-time career pick up part-time work, board seats, or consulting arrangements, sometimes purely for the attached health benefits. If you’re not ready to fully disengage from work anyway, this could potentially solve two problems with one decision.

Medicaid rarely comes up in conversations with high-W-2 professionals, but it should be evaluated as part of a comprehensive assessment. Medicaid eligibility is based on current income, not lifetime assets, so a retirement year with an unusually low income, before Social Security starts, before RMDs begin, could theoretically qualify a household. It’s a narrow lane for many people, but not a nonexistent one.

The point isn’t that one of these options is automatically right for you. It’s that most people default to COBRA or the Marketplace simply because those are the two everyone talks about, without ever pricing out other potential options.

The Income-Planning Twist Nobody Warns You About

Here’s where health coverage and tax planning collide, and it catches even careful planners off guard.

Marketplace premium tax credits are based on your Modified Adjusted Gross Income, or MAGI. For 2026 coverage, a household generally must have income between 100% and 400% of the federal poverty level to qualify for federal premium tax credits. Crossing that 400% line, even by a single dollar, can eliminate the subsidy.

A Roth conversion, a large capital gains sale, or a bigger IRA withdrawal all count as income for this calculation. Do enough of it in the same year you’re relying on a Marketplace plan, and you can push your household past that 400% line without meaning to, and not find out until the tax return shows the subsidy is gone.

Most people build their withdrawal strategy around minimizing taxes. Few think to weigh it against health insurance costs at the same time, since on paper the two look like separate decisions. An experienced financial planner treats them as one. Before a Roth conversion gets scheduled, before a large gain gets harvested, they can help you weigh what it does to your tax bill and your coverage costs together, not one at a time.

Sequencing the Bridge Without a Gap

Choosing the right coverage option matters. So does the order you move through it.

Here’s the sequence, step by step:

1. Confirm your last day of coverage. Get this in writing from HR. Some employers end coverage on your last day worked. Others carry it through the end of that month.
2. Start your Marketplace shopping right away. Once your coverage ends, you have 60 days to enroll under a Special Enrollment Period. Don’t wait until the deadline. Shop early so you’re not rushed.
3. Know your start date. A new Marketplace plan usually begins the first of the month after you enroll. Enrolling early in your 60-day window means a shorter gap, sometimes none at all.
4. Stay on that plan until 65. This is your bridge. It carries you until Medicare eligibility begins.
5. Watch for your Medicare enrollment window. It opens three months before your 65th birthday and closes three months after. 

These dates and deadlines are the same for everyone. Knowing them ahead of time and having a plan mapped out before you give notice can help you not miss an important step along the way.
