You built the wealth to retire at 58. You modeled the portfolio, stress-tested the withdrawal rate, and lined up the legacy plan. Then your advisor asks the question that derails more early-retirement plans than market volatility ever does: What are you doing for health insurance until Medicare kicks in at 65?
This is the pre-Medicare gap, and for high earners, it is less about affordability than about avoiding an expensive, badly structured mistake during the seven years before federal coverage begins.
Why the gap is trickier than it looks. Medicare eligibility starts at 65. Retire before then, and you lose the employer plan that quietly handled this for your entire career. Worse, retirement often reshapes your taxable income, which can interact with health coverage decisions in ways that surprise people who have never shopped for an individual plan. The instinct is to default to COBRA. It is the familiar option and is frequently the most expensive, capped at 18 months and priced at the full, unsubsidized premium plus an administrative fee.
The options most early retirees overlook:
- COBRA works as a short stopgap but rarely as a multi-year solution, given the cost and the 18-month limit.
- An individual ACA plan offers comprehensive coverage and, depending on how you structure withdrawals and realize income, can be paired with strategies that manage your effective cost.
- Short-term coverage has changed in a way that few people have caught up to. Short-term does not really mean short-term anymore. Following the 2025 federal shift to non-enforcement, you can now lock in short-term health insurance for up to three years in most states. For a healthy early retiree who simply needs a robust bridge to 65, a multi-year short-term plan can be a flexible, cost-efficient anchor rather than the four-month patch it used to be.
This is a planning decision, not a shopping decision. For someone with a complex balance sheet, the health coverage choice ripples into tax planning, withdrawal sequencing, and even Roth conversion strategy. Pick the wrong plan, and you can inadvertently inflate your costs or complicate your income picture. This is why the savviest early retirees treat the pre-Medicare bridge as a line item in the financial plan and bring in a coverage specialist to run it alongside their advisor, rather than clicking a plan online the week before they hand in their notice.
The takeaway. Retiring early is a triumph of planning. The health coverage bridge deserves the same rigor as the rest of the plan. Map the full seven-year stretch, weigh COBRA against an individual plan against a multi-year short-term option, and structure the choice around your income strategy, not just the premium. Handle the gap well, and it becomes a footnote. Handle it carelessly, and it becomes the most expensive oversight in an otherwise flawless retirement.
