What Is Insurance Policy Rescission? Your Rights Under the ACA

Insurance policy rescission is the retroactive cancellation of a health insurance policy — meaning your insurer cancels your coverage not from today, but backward in time, as if the policy never existed. The result: claims that were already paid get reversed, providers seek payment from you directly, and you are left without coverage you thought you had.

Rescission was once a widely used tactic by insurers to void coverage after expensive claims were filed. The Affordable Care Act dramatically curtailed this practice, but it has not been eliminated entirely. Understanding when rescission is legal — and when it is not — can make the difference between losing your coverage and keeping it.

The Pre-ACA Era of Rescission

Before the ACA, insurers routinely conducted "post-claims underwriting" — scrutinizing applications for errors or omissions only after a large claim was filed. If a policyholder failed to disclose a prior condition (even an unrelated one), the insurer would rescind the policy entirely, voiding all claims and often leaving the patient with a six-figure hospital bill.

Congressional investigations in 2008 revealed that major insurers had rescinded thousands of policies, saving hundreds of millions of dollars in claims. The practice drew bipartisan condemnation and became a driving force behind ACA reform.

What the ACA Says About Rescission

The ACA, effective 2010, prohibits rescission of health coverage except in two narrow circumstances:

1. Fraud: The policyholder intentionally misrepresented material information on the application.
2. Intentional misrepresentation: Deliberate deception about a material fact that would have affected the insurer's decision to offer coverage.

Critically, the ACA bars rescission based on innocent errors or omissions, clerical mistakes, or the failure to disclose conditions the policyholder was unaware of. If your policy is rescinded for anything short of intentional fraud, it is a violation of federal law.

Notice Requirements Before Rescission

Even when rescission is legally justified, the insurer must:

• Provide you with at least 30 days advance written notice before the rescission takes effect.
• Give you the opportunity to appeal the rescission before it becomes final.

If you received less than 30 days notice, or no notice at all, the rescission procedure itself is defective and should be challenged.

State Protections Beyond the ACA

Many states provide additional protections against rescission. Some states require incontestability clauses that bar rescission after a policy has been in force for a specified period (commonly two years), regardless of any misrepresentation. Others place stricter standards on what constitutes "material" misrepresentation.

Check your state's insurance code and contact your state insurance commissioner to understand the full scope of protections available to you.

How to Appeal a Rescission

If your insurer has moved to rescind your policy or has already done so, act immediately. The appeals process for rescission follows the same structure as other adverse benefit determinations under the ACA.

Step 1: Request the full basis for rescission. Your insurer must tell you exactly what information it claims was misrepresented or fraudulent, and how it discovered the issue. Request the complete file.

Step 2: Document the facts. If the rescission is based on an alleged omission from your application, gather evidence showing the omission was innocent — medical records, statements from your treating physician confirming you were unaware of the condition, or proof that the condition was not material to coverage.

Step 3: File an internal appeal. Submit a written appeal challenging the factual and legal basis for the rescission. Argue that the ACA prohibits rescission for anything short of intentional fraud, and that your circumstances do not meet that threshold.

Step 4: Request External Independent Review: Complete Guide" class="auto-link">external review. Under the ACA, rescission decisions are subject to independent external review. This is a critical protection — an independent reviewer is not beholden to the insurer and must apply federal law.

Step 5: File a complaint. Contact your state insurance commissioner and the federal CMS marketplace (if your plan is ACA-compliant) to report the rescission. Regulatory scrutiny often motivates insurers to reverse improper rescissions quickly.

What About Short-Term Health Plans?

Short-term limited duration insurance (STLDI) plans are not subject to ACA rescission protections. If you purchased a short-term plan, your contract terms govern. These plans frequently contain broad rescission clauses and should be read carefully before enrollment.

Rescission vs. Cancellation vs. Non-Renewal

Rescission (retroactive cancellation) is distinct from:

• Prospective cancellation: Ending coverage going forward, which has its own procedural requirements.
• Non-renewal: Declining to renew coverage at the end of a plan term.

These actions may be more easily justified by an insurer, but rescission — going backward — is the most severe and the most tightly regulated.

Fight Back With ClaimBack

If your insurer has rescinded or threatened to rescind your health insurance policy, you have strong legal protections under the ACA and state law. ClaimBack helps you build a comprehensive appeal challenging the rescission before your coverage is lost.
