One in five health insurance claims gets denied, according to Kaiser Family Foundation research. Yet fewer than 1% of people ever appeal.
Here’s what most don’t realize: 44% of internal appeals succeed. You have more power than you think.
This guide gives you a clear roadmap to fight back. You’ll learn exactly what to do, when to do it, and how to win.
Key Highlights
- 44% of internal appeals succeed in overturning denials.
- You typically have 180 days to file an appeal.
- External reviews are free and legally binding on insurers.
- Most denials stem from administrative errors, not medical judgment.
Let’s break down exactly how the appeal process works and what you need to do at each step.
Why Health Insurance Claims Get Denied?
Understanding the reasons for claim denial is your first step toward winning an appeal.
| Denial Type | What It Means? |
|---|---|
| Not medically necessary | Insurer says treatment wasn’t required |
| Missing pre-authorization | Prior approval wasn’t obtained |
| Out-of-network provider | Provider not in plan’s network |
| Coding/billing errors | Administrative mistakes on claim |
| Benefit exclusion | Service not eligible under plan |
Most denials stem from administrative or procedural issues rather than actual medical judgment.
That means many denials are essentially paperwork problems that can be corrected.
Your denial letter and Explanation of Benefits (EOB) will tell you exactly why your claim was rejected.
This is your roadmap for building a successful appeal.
First Steps to Appeal a Health Insurance Claim Denial
Don’t panic. Take a breath and act strategically.
1. Don’t discard any documents
2. Check your deadline (typically 180 days from denial)
3. Gather documentation: EOB, medical records, and policy details
4. Contact your doctor’s office for support
5. Use HSA funds strategically if you need to pay upfront while appealing
If you have a Health Savings Account, you can pay the disputed amount with HSA funds while your appeal is pending.
If you win, request reimbursement from your insurer and deposit those funds back into your HSA tax-free.
The Health Insurance Appeal Process: Internal and External Reviews
The health insurance appeal process has two main levels that give you multiple chances to win.
Internal Appeal
This is your formal request asking the insurer to reconsider.
They must respond within 30 days for services not yet received or 60 days for services already provided, and about 44% of internal appeals succeed.
External Review
If internal appeal fails, request an external review. An independent third party reviews your case. This is especially powerful for a medical necessity appeal.
It’s free under the ACA, and the decision is legally binding.
Standard reviews take up to 45 days. Urgent cases get decisions within 72 hours.

How to Win Your Medical Necessity Appeal?
Strong documentation is the key to winning your medical necessity appeal.
- Get a letter of medical necessity from your doctor
- Include relevant medical records and test results
- Reference clinical guidelines supporting your treatment
- Submit via certified mail for proof of receipt
- Follow up regularly without being aggressive
- Request expedited review for urgent health situations
Your doctor can be your greatest ally in this process. Many providers have experience fighting insurance denials and can write compelling letters explaining why your treatment is essential.
Additional Resources and When to Get Help?
Sometimes you need backup to win your appeal.
Free Resources Available to You:
- State Insurance Commissioner: can investigate complaints and offer consumer assistance
- Patient Advocate Foundation: free case management services for complex appeals
- State Consumer Assistance Programs: help with filing appeals and understanding your rights
When to Consider Professional Help:
- High-dollar claims like surgery or hospitalization
- Repeated denials for ongoing treatment
- Complex medical necessity disputes
- Time-sensitive or life-threatening situations
Financial Considerations During Your Appeal
Managing money while fighting a denial can feel overwhelming.
If you’ve already received the service, ask your provider to place your account on hold during the appeals process.
Many medical offices will pause billing while you fight the denial. This prevents unnecessary stress and potential collections activity.
You can also negotiate payment plans with providers if needed. Some hospitals and clinics offer financial assistance programs for patients dealing with insurance disputes.
Don’t be afraid to ask about your options.
When Traditional Insurance Isn’t Working for You?
If you’re constantly battling denials, it may be time to explore other options.
Some health sharing programs operate with a fundamentally different model. Members know upfront what’s eligible for sharing, eliminating the traditional denial process entirely.
There’s no adversarial relationship like you often find with conventional insurance.
HSA-qualified plans can also provide more flexibility and control over your healthcare dollars. Consider your options carefully during open enrollment.
Sometimes the best solution is finding a plan that actually works for your family’s needs.
Take Control of Your Healthcare
A denial is frustrating, but it’s not final.
Armed with the right knowledge and persistence, you can successfully fight back. The statistics prove it: those who appeal often win.
Don’t let an insurance company’s first answer be the last word on your healthcare.
Remember, you have legal rights that protect you throughout this process. The Affordable Care Act guarantees your right to appeal and to request an independent external review. Use these protections to your advantage.
