Introduction: Getting a Claim Denied Isn’t the End
Receiving a denial letter from your health insurance provider can be frustrating, especially when you were counting on that coverage. But the good news is—you have the right to appeal.
In the United States, health insurance companies are required by law to give you a clear explanation for a denied claim and provide instructions on how to challenge the decision. Understanding the appeals process can help you fight back and potentially reverse the outcome.
Before jumping into an appeal, it’s important to know why your claim was denied. Common reasons include:
Incorrect medical coding or paperwork errors
Out-of-network provider usage
Lack of prior authorization
Treatment deemed “not medically necessary”
Missing or incomplete documentation
Exceeding coverage limits
Your Explanation of Benefits (EOB) or denial letter will provide the official reason. This is your starting point.
2. Review Your Denial Letter Carefully
When you receive a denial, the insurer must send a written explanation that includes:
Reason for the denial
The specific policy rule or limitation they used
Instructions for submitting an internal appeal
Timeframes for appeal
Tip: Never ignore a denial letter. There’s a limited window (typically 180 days) to start an appeal.
3. Understand the Two Types of Appeals
There are two general types of appeals:
A. Internal Appeal
You ask your insurance company to review and reconsider the decision.
B. External Review
If the internal appeal fails, you can request an independent organization (outside the insurer) to review your case. This process is legally binding.
Most appeals start internally before moving to external review.
4. How to File an Internal Appeal
Step 1: Contact Customer Service
Start by calling your insurance provider. Clarify the reason for denial and ask for a claims representative to assist with next steps.
Step 2: Gather Your Documents
You’ll need:
The denial letter
A copy of your insurance policy or Summary of Benefits
Medical records or doctor’s notes supporting your treatment
A letter from your healthcare provider explaining medical necessity
Step 3: Write an Appeal Letter
A clear, professional letter can make all the difference. Include:
Your full name and policy number
Date of the denied service
Reason for your appeal
Supporting documents
Your contact information
Attach all supporting materials and send it by certified mail or through the insurer’s online portal, if available.
5. Sample Appeal Letter Outline
Subject: Request for Internal Appeal – Claim Denial for [Service] on [Date]
Dear [Insurance Company Name],
I am writing to formally appeal the denial of my insurance claim for [procedure/service] received on [date]. I believe this treatment was medically necessary and covered under my health plan.
Please find attached documentation from my physician, along with my medical records, which demonstrate the need for this service.
I request a full and prompt review of this decision.
Under federal law, insurance companies must respond within:
72 hours for urgent medical needs
30 days for claims involving future services
60 days for services already received
If your appeal is denied again, you have the right to request an external review through a state agency or certified review organization.
7. How to Request an External Review
If your internal appeal doesn’t succeed, the insurer must notify you of your right to an external review. This is done through a third-party reviewer and is usually free.
Submit your request within 4 months of receiving the final denial. Include:
The denial letter
Your original appeal documentation
Any new information or letters from your doctor
The decision made during the external review is final and binding.
8. Tips for a Successful Appeal
Stay organized: Keep copies of all documents and correspondence.
Follow deadlines strictly: Appeals are often rejected simply for being late.
Be detailed, not emotional: Focus on facts and documentation, not frustration.
Work with your doctor: Their support can significantly strengthen your case.
Know your rights: The Affordable Care Act guarantees your right to an appeal and external review.
9. When to Get Help
If you’re overwhelmed or unsure, you can get assistance from:
State insurance departments
Health insurance ombudsmen
Legal aid organizations
Employee benefits coordinators (if the insurance is employer-sponsored)
They can help guide you through the appeals process and even advocate on your behalf.
10. Final Thoughts: You Don’t Have to Accept “No”
Health insurance denials are more common than people think—but many are overturned on appeal. With the right documentation, persistence, and understanding of the system, you can improve your chances significantly.
Always remember: You have rights. You have options. And you can take actiom.
