Do not leave employer coverage until you can name the next coverage route, its enrollment window, its full household cost, and the fallback if income or timing changes. The healthcare bridge is a coverage sequence, not one premium estimate.
This guide is U.S.-focused and educational. It recommends no insurer, broker, plan, or coverage product. Plan availability, networks, household eligibility, and state rules need to be checked against the official enrollment sources and the plan documents in force when coverage changes.
Mark the bridge on a calendar
Medicare is generally health insurance for people age 65 or older, with eligibility for some younger people based on disability or specific conditions. A FIRE plan that leaves job-based insurance before age 65 therefore needs another coverage route for the intervening months or years.
Start with the last day of current coverage, not the last day of work. Record the birth months and coverage status of every household member. One spouse may reach Medicare while another still needs a Marketplace, employer, retiree, or continuation plan.
Protect the enrollment window
HealthCare.gov says losing job-based coverage when retiring qualifies for a Marketplace Special Enrollment Period. Its retiree guidance says an application may be made from 60 days before through 60 days after the separation date. The same page lists annual Open Enrollment as November 1 through January 15.
Do not build the plan around remembering those dates later. Save the coverage termination notice, confirm the enrollment deadline on the official Marketplace or state exchange, and decide who is responsible for the application. A missed window can turn a budget problem into a coverage problem.
Compare routes, not slogans
Marketplace coverage is one route. The application determines eligibility for premium tax credits, lower out-of-pocket costs, Medicaid, or CHIP based on the household information entered. A spouse's employer plan, retiree coverage, or continuation coverage may provide another route. Compare the actual network, formulary, deductible, out-of-pocket limit, and household premium—not the metal label or monthly premium alone.
The U.S. Department of Labor says federal COBRA generally applies to private-sector group plans offered by employers with at least 20 employees. For job loss other than gross misconduct or a reduction in hours, the maximum continuation period is generally 18 months. The worker usually pays the full premium, including the former employer share, plus 2%.
HealthCare.gov also warns that voluntarily ending COBRA outside Open Enrollment does not by itself create a Marketplace Special Enrollment Period. Exhausting COBRA can qualify. That timing rule is a reason to compare COBRA and Marketplace coverage before electing or dropping either route.
Treat income as a coverage input
Marketplace assistance is tied to expected household income, not only wages. That makes the healthcare bridge part of the withdrawal plan.
HealthCare.gov says IRA and 401(k) withdrawals generally count as income for a Marketplace application. It directs applicants to the tax rules for the taxable portion. A large conversion, gain realization, or retirement-account withdrawal can therefore affect the income entered for coverage assistance even when annual spending is unchanged.
This is where a tax professional and the official Marketplace application may be worth using. The site does not calculate premium-tax-credit eligibility, recommend an income target, or give tax advice.
Put the full cost into the FIRE case
Use annual premium plus expected out-of-pocket spending in the FIRE Number and Timeline Planner. Enter the higher pre-Medicare total in early-retirement spending, begin later-retirement spending when the household cost changes, and run lower-use and higher-cost cases rather than one precise guess. The planner separates working and coast contribution phases, early- and later-retirement spending phases, and two durable-income streams with start ages. The planner still does not estimate subsidies, plan networks, deductibles, tax effects, or household members reaching Medicare on different dates.
The comparison is still useful. It shows whether healthcare was missing from the annual spending entered and how a larger spending case changes the target and timeline. Keep the source quotes, plan documents, and renewal date beside the model; Marketplace premiums and plan terms can change.
The decision test
The bridge is ready when every household member has a dated coverage route, the enrollment action is assigned, the full cost fits a tested spending case, and there is a fallback if the preferred plan or expected income changes. “We will use the Marketplace” is not yet a bridge.
