AI Insurance Denials: What You Need to Know and How to Appeal

The Rise of AI in Insurance Claim Decisions

Artificial intelligence is increasingly embedded in health insurance workflows—from initial claim screening to coverage determinations. While AI can process claims faster and flag potential issues, it also raises a critical concern: what happens when an algorithm denies your claim, and you don't understand why?

Insurance companies have long used automated systems to review claims. But modern AI systems are more sophisticated, more opaque, and more consequential than ever before. A patient might receive a denial letter that cites "medical policy" or "coverage guidelines" without realizing that an AI model—not a human doctor—made the initial decision.

The challenge is that federal oversight of AI in health insurance remains limited, leaving states to shape their own rules. Some states, like Maryland, have begun passing laws to require human review before AI-driven denials take effect. Others have not. This patchwork means your protections depend partly on where you live and which insurer you use.

What Protections Exist Against AI-Based Denials?

Currently, there is no comprehensive federal ban on AI making claim decisions alone. However, several layers of protection do exist—and understanding them is crucial when you face a denial.

State-level safeguards. A growing number of states are recognizing the risk. Maryland, for example, passed legislation requiring that an AI system cannot be the sole basis for a coverage denial; a licensed healthcare provider must review and approve the decision. Other states are considering similar measures. Check your state's insurance commissioner's office or department of insurance website to learn what rules apply in your jurisdiction.

Federal appeal rights. Even if an AI system made the initial denial, you have the right to appeal. HealthCare.gov outlines your right to request an internal appeal and, if necessary, an external review. During an appeal, a human reviewer—ideally someone with medical expertise—must reconsider your case. This is your opportunity to challenge not just the decision, but the logic behind it.

Transparency requirements. Under the Affordable Care Act, insurers must provide you with an explanation of benefits (EOB) and, upon request, information about how they made their decision. If an AI system was involved, you can ask for details about the criteria it used. While insurers may claim trade secret protections, you are entitled to enough information to understand and contest the denial.

CMS provides a fact sheet on external review rights, which is a formal process where an independent third party reviews your case if your internal appeal is denied. This is a powerful tool when you believe an insurer's decision—whether AI-driven or not—was wrong.

How to Challenge an AI-Based Denial

If you suspect that an algorithm played a role in your denial, here's what you can do:

• Request a detailed explanation. Call your insurer and ask specifically how the denial decision was made. Ask whether any automated systems or AI tools were used. Request written documentation of the criteria applied. Many insurers will disclose this information if you ask directly.
• File an internal appeal. This is your first formal step. In your appeal letter, note that you are challenging the decision and request human review. If you believe an AI system made an error—such as misclassifying your procedure or applying an outdated guideline—say so explicitly. Provide clinical evidence, your doctor's notes, and any peer-reviewed studies that support medical necessity.
• Involve your healthcare provider. Your doctor can submit a peer-to-peer review request, in which they speak directly with the insurer's medical director. This human-to-human conversation often carries more weight than a written appeal, especially when challenging an automated decision.
• Escalate to external review. If your internal appeal is denied, you have the right to an independent external review. This is particularly valuable if you believe the insurer's criteria were applied incorrectly or if the decision contradicts standard medical practice.
• Document everything. Keep copies of all denial letters, appeal submissions, and correspondence. Note dates and names of anyone you speak with. This record is essential if you need to escalate further or file a complaint with your state insurance commissioner.

The key insight: an AI-based denial is still a denial, and you have the same appeal rights as you would for any other denial. The fact that an algorithm was involved does not strip away your right to human review and reconsideration.

Red Flags That AI May Have Played a Role

You may not always know if AI was involved in your denial. However, certain patterns can suggest it:

• The denial letter uses vague language like "does not meet medical policy" without specific clinical reasoning.
• The denial seems inconsistent with your diagnosis, your doctor's recommendation, or similar approvals you received in the past.
• The insurer denies a procedure that is standard of care for your condition.
• The denial cites a guideline or policy that your doctor disputes or says is outdated.
• The timeline is very fast—the claim was processed and denied within hours or a day, suggesting minimal human review.

None of these alone proves AI was involved, but they are worth investigating. When you appeal, ask your insurer directly whether automated systems were used in the decision.

The Bigger Picture: Why This Matters

The use of AI in insurance decisions is not inherently wrong. Algorithms can catch errors, flag unusual patterns, and speed up routine approvals. The problem arises when AI systems are used to deny care without adequate human oversight or transparency.

KFF research on claims denials and appeals in ACA marketplace plans shows that many patients do not appeal denials, often because they don't know they can or don't understand the process. When AI is the decision-maker, this knowledge gap becomes even more dangerous. A patient may assume that a computer's decision is final or unchallengeable—but it is not.

As more states pass AI oversight laws and federal regulators consider stronger rules, your immediate power lies in knowing your appeal rights and using them. An AI-based denial is not the end of the story; it is the beginning of your appeal.

Frequently Asked Questions

Can an insurance company use AI to deny my claim without any human review?

It depends on where you live. Some states, like Maryland, now require human review before an AI-driven denial is final. In other states, there is no such requirement at the state level. However, federal law gives you the right to appeal any denial and request human review. If you believe an AI system made an error, you can challenge it through the appeal process. ClaimCure recommends always requesting an internal appeal if you receive a denial, regardless of whether you suspect AI involvement.

What should I say in my appeal letter if I think AI made the wrong decision?

Be specific and clinical. Explain why the denial is wrong based on medical evidence: your diagnosis, your symptoms, your doctor's clinical judgment, and relevant medical guidelines or studies. You can note that you believe an automated system may have misapplied criteria or failed to account for your individual circumstances. Request that a licensed healthcare provider review your case. Provide your doctor's contact information so the insurer can conduct a peer-to-peer review. The more detailed and evidence-based your appeal, the stronger your case.

How long do I have to appeal an AI-based denial?

Federal law typically allows 180 days from the date of the denial to file an internal appeal. Some insurers may have shorter timelines, so check your denial letter for the specific deadline. If your internal appeal is denied, you generally have 4 months to request an external review. Do not wait; file your appeal as soon as possible. Missing a deadline can forfeit your right to appeal.

Can I ask my insurance company to explain how the AI made its decision?

Yes. You have the right to request information about how your claim was decided. Ask your insurer specifically whether an AI system was used and, if so, what criteria it applied. The insurer may claim that the algorithm's logic is proprietary, but you are entitled to enough information to understand and contest the decision. If the insurer refuses to provide any explanation, that is a red flag worth raising in your appeal or with your state insurance commissioner.
