Getting a letter from your health insurer that says “Denied” can make your heart sink. Whether it’s for a surgery, prescription, or test, it feels unfair — especially when you’ve done everything right.
But here’s the truth: a denial isn’t the end of the story.
Thousands of people win their appeals every year simply because they understand the process, stay organized, and don’t give up. This step-by-step guide shows you how to do the same — turning that “no” into a well-earned “yes.”
1. Understand Why Your Claim Was Denied
Before taking action, read the denial letter carefully. It will explain why your claim was rejected — and that reason determines your next move.
Common reasons include:
-
Missing pre-authorization
-
Provider out of network
-
Service not covered under your plan
-
Incorrect coding or missing documents
-
“Not medically necessary”
💡 Useful Example:
Elena from San Diego had her MRI denied because her provider forgot a referral code. Once her doctor resubmitted the corrected paperwork, her claim was approved within two weeks.
✅ Guide Tip: Don’t assume it’s your fault. Many denials result from clerical or coding errors, not actual coverage issues.
2. File an Internal Appeal — the Right Way
You have the legal right to appeal within 180 days of receiving your denial letter. This is your first and most important chance to reverse the decision.
Here’s how to do it right:
-
Write a clear appeal letter — include your name, policy number, claim number, and a short explanation of why the denial is incorrect.
-
Attach supporting evidence — medical records, prescriptions, invoices, and your doctor’s notes.
-
Ask your doctor for support — a professional statement about “medical necessity” often makes a strong impact.
💡 Useful Example:
Carlos from Fresno had knee surgery denied. After submitting his doctor’s letter and updated records, his insurer approved the $6,200 claim within 30 days.
✅ Guide Tip: Keep a copy of everything — letters, attachments, and mailing proof. Organization is your best defense.
3. Request an Expedited Appeal When Time Is Critical
If your health could be at risk by waiting, you can file an expedited appeal, which insurers must review within 72 hours (often faster).
💡 Useful Example:
Marcy’s heart medication refill was denied. Her doctor marked the appeal as urgent — the insurer approved it within 24 hours.
✅ Pro Tip: Use words like urgent, time-sensitive, or life-threatening in your letter to trigger immediate review.
4. Escalate to an External Review
If your internal appeal is denied, don’t stop there. You have the right to request an external review, meaning an independent medical expert reviews your case — not your insurer.
Here’s why it matters:
-
It’s free or low-cost.
-
The decision is binding — your insurer must honor it.
-
Instructions are always in your denial letter.
💡 Useful Example:
Dylan from Sacramento appealed a denied mental health treatment. After an external review, an independent expert overturned the decision — his insurer paid over $8,000 in therapy costs.
✅ Guide Tip: Treat this like your “second chance.” Provide clear facts, strong evidence, and keep emotion out of your paperwork.
5. Keep Everything Documented
Good records can make or break your appeal. Save and organize every piece of communication.
Keep:
-
Copies of all letters, emails, and forms
-
Notes from phone calls (with names, dates, and reference numbers)
-
Explanation of Benefits (EOBs) and denial letters
✅ Pro Tip: Scan and store everything digitally. Use your insurer’s online portal or a secure cloud folder so you can access files anytime.

7. Know Your Rights
Under the Affordable Care Act (ACA), you have legal rights that protect you during the appeal process:
-
To receive a clear reason for any denial
-
To file an internal appeal
-
To request an independent external review
-
To ask for expedited review in urgent cases
✅ Pro Tip: If your insurer isn’t cooperating, contact your state insurance department — they enforce these laws.
8. Get Expert Help When Needed
If the process feels too complex, don’t hesitate to ask for help. You’re not alone.
You can reach out to:
-
Your State Insurance Department: Free consumer advocates can assist.
-
Patient Advocacy Nonprofits: Groups like the Patient Advocate Foundation offer free guidance.
-
Licensed Insurance Advisors: For complex cases, they can spot insurer errors and speed up results.
💡 Useful Example:
Priya from Los Angeles got help from a nonprofit advocate. Together, they refiled her claim with better documentation — the insurer reversed the denial within 10 days.
✅ Guide Tip: Getting support isn’t a weakness — it’s strategy.
A denied claim isn’t a closed door — it’s just a challenge waiting to be resolved.
With persistence, good documentation, and the right steps, you can transform that dreaded “Denied” letter into a confident “Approved.”
Remember: insurers count on people giving up. But when you stay calm, organized, and informed — you win.
