Yes, you can sue a health insurance company for negligence, but only under specific circumstances and usually only after you have exhausted the required appeals process. Your health insurance policy is a legal contract. When the insurer fails to uphold its end of that contract by wrongfully denying claims, unreasonably delaying payments, or acting in bad faith, you may have grounds for legal action.
However, suing your insurance company is not your first step. Federal and state laws require you to go through internal and external appeals before filing a lawsuit. The Affordable Care Act (ACA) guarantees your right to appeal any claim denial, first through your insurer’s internal review process, and then through an independent external review.
If those appeals fail and you believe your insurer acted negligently or in bad faith, the law in most states allows you to file a lawsuit. The type of lawsuit you can bring depends on whether the insurer simply made a mistake (breach of contract) or deliberately acted unfairly (bad faith). Bad faith claims can result in significantly larger damages, including punitive damages in some states.
The numbers show why this matters. According to data analyzed by MoneyGeek from CMS Transparency in Coverage reports, approximately 19% of in network health insurance claims on the ACA Marketplace were denied in 2024. That means roughly one in five claims gets rejected. An NPR report noted that major insurers like UnitedHealthcare, Cigna, and Humana faced class action lawsuits over their use of AI to bulk process claim denials, with 90% of those denials reversed upon appeal.
What Counts as Negligence by a Health Insurance Company?
Negligence in the insurance context means the company failed to meet its duty of care to you as a policyholder, causing you financial harm or a worsening of your health condition.
Insurance companies have a legal obligation to handle your claims fairly and in good faith. When they breach that duty, it can take several forms:
Wrongfully denying a claim that your policy clearly covers. Failing to properly investigate your claim before denying it. Unreasonably delaying payment on an approved claim. Failing to inform you about policy terms, coverage changes, or deadlines. Misrepresenting what your policy covers or does not cover. Using automated systems to deny claims without individual review. Refusing to pay for medically necessary treatments that meet your plan’s criteria.
Not every denied claim qualifies as negligence. Insurance companies can legitimately deny claims when the service is not covered under your plan, when you have not met your deductible, when pre authorization was required but not obtained, or when the provider is out of network and your plan does not cover out of network care. The difference between a legitimate denial and negligence comes down to whether the insurer acted reasonably and in good faith.
What Is the Difference Between Negligence and Bad Faith?
These two legal concepts overlap but carry different weight in court.
| Legal Claim | Definition | What You Must Prove | Potential Damages |
| Breach of contract | The insurer violated the terms of your policy | The policy covers the service and the insurer refused to pay | The amount of the denied claim plus interest |
| Negligence | The insurer failed to meet its duty of care | The insurer had a duty, breached it, and caused you harm | Actual damages (medical costs, lost wages, out of pocket expenses) |
| Bad faith | The insurer intentionally or recklessly denied a valid claim | The insurer acted unreasonably, dishonestly, or without proper investigation | Actual damages plus consequential damages, attorney fees, and potentially punitive damages |
Bad faith is harder to prove but carries far greater consequences for the insurer. A 2025 report from Legal Reader found that claims handling issues accounted for 62.5% of all insurance complaints filed in 2024, with delays and unsatisfactory settlements among the most common problems.
Some states, like California, have strong consumer protection laws that allow policyholders to recover significant damages for bad faith. A few states, like Michigan, do not recognize first party bad faith insurance claims, meaning your legal options may be more limited depending on where you live.
When Should You Consider Suing Your Health Insurance Company?
Not every disagreement with your insurer warrants a lawsuit. Here are situations where legal action may be justified:
Your Claim Was Denied Without a Valid Reason
If your insurer denies a claim for a service that your policy clearly covers and cannot provide a legitimate reason for the denial, you may have grounds for a breach of contract or bad faith claim.
Your Insurer Failed to Investigate
Insurance companies must conduct a reasonable investigation before denying a claim. If your insurer denied your claim without reviewing your medical records, consulting with your doctor, or considering all relevant information, that failure may constitute negligence.
You Suffered Harm Because of the Denial
If a claim denial forced you to delay medically necessary treatment, pay thousands in out of pocket costs, or caused your health condition to worsen, the resulting damages strengthen your case.
Your Insurer Used AI to Auto Deny Claims
Recent lawsuits against major insurers have alleged that companies used artificial intelligence to process and deny claims in bulk, spending as little as 1.2 seconds per claim review according to a lawsuit filed against Cigna. If your claim was denied through an automated process without individual medical review, this may support a negligence or bad faith claim.
Your Appeals Were Ignored or Handled Improperly
If you went through the internal and external appeals process and your insurer failed to follow the required procedures, missed deadlines, or ignored evidence you submitted, their handling of your appeal may itself constitute negligence.
How to Sue a Health Insurance Company: Step by Step
Before you file a lawsuit, you must follow the proper process. Skipping steps can weaken or disqualify your case.
Step 1: Understand why your claim was denied. Request the denial letter in writing. Your insurer must explain the specific reason for the denial and tell you how to appeal.
Step 2: File an internal appeal. Ask your insurance company to reconsider its decision. Submit any additional medical records, doctor’s letters, or supporting evidence. Your insurer must complete the internal review within 30 to 60 days for non urgent claims.
Step 3: Request an external review. If the internal appeal fails, you have the right to an independent external review. An outside organization reviews your case and makes a binding decision. You typically have 60 days to file an external review after receiving the internal appeal denial.
Step 4: File a complaint with your state insurance department. Every state has a department of insurance that regulates insurers. Filing a formal complaint creates an official record of your dispute and may prompt the insurer to reconsider.
Step 5: Consult an attorney. If your appeals are exhausted and the dispute remains unresolved, consult an experienced insurance litigation attorney. Many offer free consultations. Your attorney will review your policy, your denial history, and the evidence to determine whether you have a viable case.
Step 6: File a lawsuit. If your attorney advises that you have a strong case, you can file a lawsuit in state or federal court. The type of claim (breach of contract, negligence, or bad faith) will depend on the facts of your case and your state’s laws.
What Damages Can You Recover?
The damages available to you depend on the type of claim you bring and your state’s laws.
Breach of contract: You can typically recover the amount of the denied claim, meaning the insurer pays the medical bills it should have covered in the first place, plus interest.
Negligence: You may recover actual damages, including medical expenses you paid out of pocket, costs of delayed treatment, lost wages if your health condition affected your ability to work, and related financial losses.
Bad faith: In addition to actual damages, many states allow you to recover consequential damages (financial harm caused by the denial, such as damage to your credit score or loss of your home), attorney fees and court costs, and punitive damages designed to punish the insurer for egregious conduct.
Punitive damages can be substantial. In some high profile cases, courts have awarded millions in punitive damages against insurance companies that deliberately harmed policyholders. However, these awards are not guaranteed and vary widely by state.
Real Life Scenarios
Scenario 1: Emergency Surgery Denial
Mark, a 45 year old construction worker, suffers a heart attack and needs emergency bypass surgery. His health insurance plan covers emergency cardiac procedures. The insurer denies the claim, stating the surgery was “not medically necessary.” Mark’s cardiologist submits detailed records showing the surgery was urgent and life saving. The internal appeal fails. An independent external reviewer overturns the denial. Had the external review also failed, Mark could have filed a bad faith lawsuit because the denial contradicted clear medical evidence and the terms of his own policy.
Scenario 2: Delayed Cancer Treatment
Rachel has an ACA Marketplace plan and receives a breast cancer diagnosis. Her oncologist recommends immediate chemotherapy. The insurer delays pre authorization for eight weeks, citing a need for “additional review.” Rachel starts treatment using personal savings and a family loan. After exhausting appeals, Rachel consults an attorney who files a negligence claim. The lawsuit argues the insurer’s unreasonable delay caused Rachel financial harm and unnecessary suffering.
Scenario 3: Prescription Coverage Dispute
David takes a specialty medication for a chronic autoimmune condition. His insurer suddenly removes the drug from its formulary mid year and denies coverage. David’s doctor submits a prior authorization showing no viable alternative exists. The insurer denies the prior authorization. After internal and external appeals fail, David’s attorney files a breach of contract claim, arguing the insurer changed coverage terms without proper notice.

What to Know Before Filing a Lawsuit?
Several practical factors affect whether a lawsuit makes sense for your situation.
Statute of limitations: Every state sets a deadline for filing insurance lawsuits. In most states, you have one to six years depending on the type of claim. Missing this deadline means you lose the right to sue entirely.
ERISA limitations: If your health insurance comes through your employer, the Employee Retirement Income Security Act (ERISA) may limit your legal options. Under ERISA, you can usually only recover the value of the denied benefit itself, not punitive or consequential damages. This is a significant limitation that does not apply to individual or ACA Marketplace plans.
Cost of litigation: Insurance lawsuits can be expensive and time consuming. Many attorneys take these cases on a contingency fee basis (they get paid only if you win), but you should understand the fee structure before committing.
Strength of evidence: The stronger your documentation, the better your chances. Keep copies of every denial letter, appeal submission, medical record, phone call log, and email. Courts look for a clear paper trail showing the insurer acted unreasonably.
How to Protect Yourself Before Problems Arise?
Taking a few simple steps now can make a huge difference if you ever need to challenge your insurer.
Read your policy carefully. Understand what your plan covers, what it excludes, and what conditions require pre authorization. Keep every document. Save all Explanation of Benefits (EOB) statements, denial letters, approval notices, and correspondence with your insurer. Know your appeal rights. Every health plan must provide information about how to appeal a denial. Ask for this information when you enroll. Stay in the network when possible. Out of network claims are denied at much higher rates than in network claims. Using providers within your plan’s network reduces your risk. Ask your doctor for help. Your physician can submit letters of medical necessity, peer to peer reviews, and supporting documentation that strengthen your appeal.
Frequently Asked Questions
Yes, but only after you exhaust the required appeals process. You must first file an internal appeal with your insurer, then request an external review by an independent organization. If both appeals fail and you believe the denial was wrongful, you can file a lawsuit for breach of contract, negligence, or bad faith depending on the circumstances and your state’s laws.
The statute of limitations varies by state and by the type of claim. Most states allow one to six years for insurance related lawsuits. ERISA claims involving employer sponsored plans may have shorter deadlines. Consult an attorney promptly after your appeals are exhausted to avoid missing your filing deadline.
Bad faith means an insurance company intentionally or recklessly fails to honor its obligations to a policyholder. Examples include denying a valid claim without investigation, offering a settlement far below the claim’s value, unreasonably delaying payment, misrepresenting policy terms, or using automated systems to deny claims without proper review. Bad faith claims can result in damages beyond the value of the original claim.
In some states, yes. If the insurer’s conduct was particularly egregious and caused you significant emotional harm, some states allow claims for emotional distress as part of a bad faith lawsuit. However, these claims are difficult to prove and are not available in all states.
While you technically can represent yourself, insurance litigation is complex and insurers employ experienced legal teams. An experienced insurance litigation attorney significantly improves your chances of success. Many attorneys offer free consultations and work on a contingency fee basis, meaning you do not pay unless you win.
Employer sponsored health plans are typically governed by ERISA, a federal law that limits the types of damages you can recover. Under ERISA, you can generally only recover the value of the denied benefit itself, not punitive damages or attorney fees. This makes employer plan lawsuits less financially rewarding but still worth pursuing if a significant claim has been wrongfully denied.
Key Takeaways
You can sue a health insurance company for negligence, breach of contract, or bad faith, but only after exhausting the appeals process.
About 19% of in network ACA claims were denied in 2024, showing that claim denials are common. Many denials are overturned on appeal, so always appeal before considering a lawsuit.
The type of damages you can recover depends on your claim type and your state’s laws. Bad faith claims may include punitive damages, while ERISA governed employer plans limit recovery to the denied benefit itself.
Document everything. Keep denial letters, appeal submissions, medical records, and all communications with your insurer.
Consult an attorney before filing a lawsuit. Many insurance attorneys offer free consultations and contingency fee arrangements.
