Moving from Marketplace or individual insurance to Medicare

By My Coverage Relay · Updated September 24, 2026

Your Marketplace plan does not automatically become Medicare. You need a confirmed Medicare start date and a deliberate end date for the coverage you are replacing. If other people share your Marketplace application, their coverage needs attention too.

Do not treat individual coverage like active employer coverage

A Marketplace or other individual policy generally does not provide the current-employment protection used to postpone Part B. Review your first Medicare enrollment opportunity even if you like your current plan. A policy purchased with business income is not automatically an employer group plan.

Understand the subsidy issue

Eligibility for premium-free Part A generally ends eligibility for Marketplace savings. Enrollment in Part A or Medicare Advantage also affects those savings. Continuing to use premium tax credits when you are not eligible can lead to repayment. If you must pay a Part A premium, different choices may be available; compare the rules and potential Medicare penalties before choosing to stay in the Marketplace.

Coordinate the dates

1. Confirm Medicare eligibility and whether you must apply.
2. Verify the effective dates for A/B and any selected health or drug plan.
3. Update the Marketplace application for the person transitioning.
4. Arrange for that person’s Marketplace coverage to end the day before the new Medicare coverage begins.
5. Confirm the remaining household members’ plan and revised financial assistance.
6. Save both the Medicare acceptance and Marketplace termination notices.

HealthCare.gov lets you report a Medicare start date up to three months in advance. Coverage does not simply stop because a birthday passed. State-based Marketplaces may use different account screens, so use the process for your own exchange.

One household, two coverage paths

Suppose one spouse starts Medicare on October 1 while the other still needs the Marketplace policy. The goal is to end the first spouse’s coverage on September 30, not cancel the entire household application. Recheck the remaining spouse’s selection and premium after the update. This is an illustration, not an eligibility determination.

If you bought insurance directly

An off-Marketplace policy will have its own termination instructions. Ask the insurer how to cancel and how any final premium is handled. Review prescription coverage separately and do not assume the old policy is a useful Medicare supplement.

Common question: Can an agent simply transfer my Marketplace policy into Medicare? No. Medicare and private Medicare-plan enrollment are distinct processes. Our agents can help you organize the decisions and enrollment steps, while the Marketplace controls its own application and coverage changes.
