Start here: If your job-based health insurance is ending, ask your employer or plan administrator for the exact final covered date and written continuation information. Then compare a Marketplace plan, COBRA if offered, and Medicaid/CHIP eligibility. Do not assume your insurance ends on your last workday—or that your next plan begins immediately. The right choice depends on dates, costs, providers, medicines and your state.
Step 1: Write down three dates
- Your last day of employment.
- The last day your current health coverage actually applies (ask HR or the insurer; do not guess).
- The earliest day a replacement plan could begin, confirmed by the Marketplace, state program, or plan administrator.
Also request a coverage-termination notice, a copy of your current plan summary, the COBRA election notice if eligible, and a list of family members who need coverage. Keep these with any Marketplace eligibility notices. A spouse's employer plan may be another option; ask that benefits administrator directly about its special-enrollment rules and deadline.
Step 2: Check the Marketplace promptly
According to HealthCare.gov's job-coverage-loss guidance, losing job-based coverage can qualify you for a Special Enrollment Period even if you quit or were fired. For the federal Marketplace example discussed there, you need to apply within 60 days of losing that coverage. Your new Marketplace coverage can start on the first day of the month after the job-based coverage ends—not on the same day it ends mid-month. State-based Marketplace rules and individual eligibility should be checked on your official exchange. Do not wait for the last day of the window.
Estimate your household income for the coverage year accurately; the Marketplace application evaluates potential premium savings and Medicaid/CHIP options. It may ask for documents proving loss of coverage. Complete plan selection, any required verification, and the first premium payment by the applicable deadlines; an eligibility notice by itself is not proof that coverage has started. Confirm the effective date with the plan.
Step 3: Compare COBRA without assuming it is cheapest
If COBRA continuation coverage is offered, it may let you keep your employer plan for a limited time, including its provider network and current benefits. The premium may be much higher because you may be responsible for the full cost plus an administrative amount. Request the written election notice and confirm its actual election, payment, effective-date and coverage rules with the plan administrator. Do not assume that choosing COBRA and later dropping it will always create a new Marketplace enrollment opportunity: check the official COBRA-versus-Marketplace guidance first. COBRA eligibility and deadlines depend on the employer and circumstances.
Step 4: Check Medicaid and CHIP, including for children
An application through the official Marketplace can identify possible Medicaid or Children's Health Insurance Program (CHIP) eligibility; you can also contact your state Medicaid agency. According to HealthCare.gov's outside-open-enrollment guidance, eligible people can apply for Medicaid or CHIP at any time of year. Eligibility and start dates depend on state rules and household circumstances. Children and adults may have different options. Check the decision notice instead of assuming everyone in the household will receive the same type of coverage.
Compare the choices on one sheet
| Check | Marketplace | COBRA, if available | Medicaid/CHIP |
|---|---|---|---|
| Start date and enrollment | Check loss-of-coverage window, effective date and first payment. | Check the written election notice, payment deadline and continuation dates. | Ask the state agency about eligibility and effective date. |
| Your likely total cost | Premium after any eligible savings + deductible, copays and out-of-pocket maximum. | Full continuation premium and cost sharing; ask how existing spending is treated. | State/program-specific costs and covered services. |
| Care you rely on | Verify exact plan network, medicines, specialists and prior authorizations. | Confirm whether your existing plan benefits and network continue. | Check participating providers and medicine coverage. |
Do not cancel existing coverage until you have confirmed the replacement's effective date and the consequences of cancellation. If dates leave a gap, ask the plan administrator and official Marketplace about available options before the old plan ends.
- Request the exact coverage-end date in writing.
- Collect the loss-of-coverage and any COBRA notices.
- Start the official Marketplace or state exchange application promptly.
- Compare realistic annual costs and verify your doctors and prescriptions with each plan.
- Save the new plan's effective-date and payment confirmation.
