How to Cancel a Health Insurance Marketplace Plan in the United States Without a Coverage Gap

Confirm the Marketplace that actually manages the plan

First identify whether the plan is managed through HealthCare.gov or a state-based Marketplace. The CMS plan-year map classifies each state as a Federally-facilitated Marketplace (FFM), a state-based Marketplace using the federal platform (SBM-FP), or an own-platform SBM. FFM and SBM-FP users follow the current HealthCare.gov account flow; only an own-platform SBM uses its state platform's current instructions.

Protect replacement coverage before ending the old plan

HealthCare.gov says not to end Marketplace coverage until the new coverage start date is certain, because ending coverage can create a gap and may mean waiting until Open Enrollment to enroll again unless a Special Enrollment Period applies. During Open Enrollment, changing to a new or different Marketplace plan does not require separately ending the old plan. Outside Open Enrollment, report the change and review the eligibility result before assuming a Special Enrollment Period or replacement plan is available.

Choose whether the request covers all or some household members

The coverage end date can differ depending on whether the request removes everyone on the application or only some household members. Review each person, the requested end date, replacement coverage, and application details before submitting. A partial household change is not the same as cancelling the whole application, and a new employer, Medicare, Medicaid, or CHIP path may have separate enrollment rules.

Use the account route and save the result

For FFM or SBM-FP coverage, log in to HealthCare.gov and answer the account questions for the cancellation path. Only an own-platform SBM user should use that state's current account or support route. Save the submitted request, effective date, covered-person list, notices, and replacement-plan confirmation. If a record appears wrong, contact the Marketplace that manages the plan before escalating.

SubsCraft tip: Keep the old plan's end confirmation beside the new plan's start confirmation so any coverage gap is visible.
