What to Do When Insurance Denies Your Claim

Getting a denial letter from your insurance company is frustrating — especially when you're already dealing with a car accident, a medical bill, or damage to your home. The good news? A denial isn't the end of the road. Insurance companies deny a large number of claims every year, and many of those denials get reversed once the policyholder pushes back the right way.

Here's a clear, no-jargon guide to what to do next.

1. Don't Panic — Read the Denial Letter Carefully

Every insurance company is legally required to tell you why your claim was denied. This explanation is usually included in a letter called an Explanation of Benefits (EOB) for health claims, or a denial letter for auto, home, or life insurance claims.

Look for:

• The specific reason for denial (missing information, policy exclusion, missed deadline, etc.)

• The policy section or clause they're citing

• The deadline for filing an appeal

• Instructions on how to appeal

If the letter is vague or confusing, call the insurer and ask them to explain the denial in plain language. Take notes, including the date, time, and the name of the representative you spoke with.

2. Understand the Most Common Denial Reasons

Knowing why claims typically get denied helps you figure out your next move:

• Missing or incorrect paperwork — a simple clerical fix can solve this

• Claim filed too late — most policies have strict filing windows

• Service or damage not covered under your policy

• Pre-existing condition exclusion (common in health insurance)

• Lapsed policy or missed premium payment

• Insufficient documentation to prove the loss or medical necessity

• Coding errors (common with medical billing)

A surprising number of denials fall into the first and last categories — meaning they're fixable without a major fight.

3. Gather Your Documentation

Before you do anything else, build a paper trail. Collect:

• A copy of your insurance policy

• The denial letter

• Medical records, repair estimates, or receipts related to the claim

• Photos or videos of damage (for home or auto claims)

• Any correspondence with the insurance company

• Notes from phone calls (date, time, representative name, what was said)

Keep everything organized in one folder — physical or digital. You'll need it for your appeal.

4. File a Formal Appeal

Every insurance policy has an appeals process, and insurers are required to tell you how to use it. Typically, this involves:

1. Writing an appeal letter that explains why you believe the denial was incorrect, referencing your policy terms and any supporting documents.

2. Attaching evidence — medical records, a letter from your doctor, repair invoices, etc.

3. Submitting before the deadline. Most insurers give you 30 to 180 days depending on the state and type of insurance, so check your denial letter for the exact window.

4. Sending it via certified mail or a trackable method so you have proof it was received.

For health insurance, you generally have the right to both an internal appeal (reviewed by the insurance company) and, if that fails, an external review by an independent third party — this is guaranteed under federal law for most health plans.

5. Ask for an External Review (If It's a Health Claim)

If your internal appeal is denied, you can request an external review. This means an independent organization — not your insurance company — takes a fresh look at your case. Their decision is usually binding, meaning the insurer has to follow it if the review favors you.

You can find your state's external review process through your state's Department of Insurance website, or through Healthcare.gov if your plan is through the Health Insurance Marketplace.

6. Contact Your State's Department of Insurance

Every U.S. state has an insurance regulator that oversees how insurance companies operate. If you believe your claim was wrongfully denied, you can file a complaint with your State Department of Insurance. They can:

• Investigate whether the insurer followed state law

• Push the insurer to respond or reconsider

• Help mediate the dispute

This step is free and often gets faster results than you'd expect, since insurers don't want repeated regulatory complaints on record.

7. Get Help From a Professional

If the claim is large or the denial feels unjustified, consider bringing in outside help:

• Public adjusters — licensed professionals who negotiate property and auto claims on your behalf (for a percentage fee)

• Patient advocates — help navigate complex medical billing and appeals

• Attorneys specializing in insurance disputes — especially useful for large claims, bad-faith denials, or if litigation becomes necessary

Many insurance attorneys offer free initial consultations and only get paid if you win, so it costs nothing to ask.

8. Watch Out for "Bad Faith" Denials

Insurance companies are legally obligated to act in good faith when handling your claim. If an insurer denies a valid claim without a reasonable basis, delays payment unnecessarily, or fails to properly investigate, this may count as bad faith insurance practice — which is illegal in every U.S. state.

Signs of bad faith include:

• Repeated, unexplained delays

• Denial without proper investigation

• Misrepresenting policy language

• Offering a settlement far below the claim's actual value

If you suspect bad faith, document everything and consult an attorney — you may be entitled to damages beyond the original claim amount.

9. Keep a Paper Trail Throughout

Whatever stage you're at, always:

• Get everything in writing when possible

• Follow up phone calls with a confirmation email

• Save copies of every document you send or receive

• Note every deadline in your calendar

This habit alone can make the difference between winning and losing an appeal.

The Bottom Line

A denied insurance claim isn't necessarily a final answer — it's often just the first round. Read the denial carefully, gather your documents, file a timely appeal, and don't hesitate to escalate to your state regulator or a professional if needed. Persistence, organization, and knowing your rights are usually what turn a "no" into a "yes."
