Can my insurance cancel my policy retroactively?

Under the ACA, only for fraud or intentional misrepresentation of a material fact, with 30 days' advance notice, or in limited situations like unpaid premiums.

Will I have to repay claims if my coverage is rescinded?

If the rescission stands, the insurer may seek repayment of claims and providers may bill you directly. That's why appealing promptly matters.

Is a mistake on my application fraud?

Not by itself. ACA rules require fraud or intentional misrepresentation. An honest error is not grounds for rescission.

Can I get new coverage after a rescission?

Loss of coverage may qualify you for a special enrollment period on the marketplace or through an employer plan, usually within 60 days.

Health Insurance Rescission: Your Rights and How to Appeal

By AppealFlow editorial•5 min read•Published October 2026

A rescission is a retroactive cancellation of your health coverage, which can leave you responsible for claims the plan already paid. Under the ACA, most plans may rescind coverage only for fraud or intentional misrepresentation of a material fact, and must give at least 30 days' advance written notice. A rescission counts as an adverse benefit determination, so you have the right to an internal appeal and, in most cases, external review.

What Counts as a Rescission?

Key Takeaway: Not every cancellation is a rescission.

A rescission is a cancellation or discontinuation with retroactive effect. Cancelling coverage going forward for non-payment of premiums is generally not a rescission; nor is a retroactive cancellation caused by a delay in paying required premiums. An employer plan that retroactively drops an employee because of an administrative delay in processing a termination may also be treated differently, as long as no premiums were paid for the period. Everything else retroactive is likely a rescission.

When Is Rescission Allowed?

Key Takeaway: The ACA set a high bar.

Only for fraud or intentional misrepresentation of a material fact, as prohibited by the plan's terms (45 CFR 147.128).
Honest mistakes on an application are not enough.
The plan must give at least 30 days' advance written notice before the rescission takes effect.
Since the ACA bars pre-existing condition exclusions in most plans, a forgotten past diagnosis on an application is rarely relevant for ACA-compliant coverage.

How Do I Appeal a Rescission?

Key Takeaway: Treat it as urgent; your coverage history is at stake.

Ask for the notice, the specific statement they say was false, and all documents they relied on.
Explain in writing why there was no fraud or intentional misrepresentation: for example, the question was ambiguous, an agent filled it in, or the information wasn't material.
Include supporting evidence: the original application, emails with an agent or HR, payroll records showing eligibility.
File the internal appeal by the deadline on the notice and request external review if it's upheld.
Contact your state insurance department, or for employer plans the Department of Labor's EBSA. See filing a state insurance complaint.

What If I'm Not on an ACA Plan?

Key Takeaway: Some coverage has weaker protections.

Short-term plans, some fixed-indemnity products, and grandfathered individual policies may not follow ACA rescission limits, though state law may still restrict rescission. If coverage is lost, you may qualify for a special enrollment period on the marketplace; apply quickly, because these windows are usually 60 days.
