Common Reasons for Claim Denial
Before we dig into how to appeal insurance claim denial, it helps to understand why claims are denied in the first place. These are some of the most common reasons:
1. Incorrect or Missing Information
- Patient details (name, DOB, insurance ID)
- Provider credentials
- CPT or ICD-10 codes
2. Lack of Medical Necessity
The payer determines that the service wasn’t required—even if it clearly was.
3. Out-of-Network Provider
Many denials occur because the provider is not part of the insurance network.
4. Service Not Covered
The procedure or service might be excluded from the patient’s policy.
5. Timely Filing
Submitting the claim after the allowed timeframe is an automatic denial.

Step-by-Step: How to Appeal a Denied Insurance Claim
Step 1: Review the Explanation of Benefits (EOB)
The first step in appealing any denial is understanding why it happened. Carefully review the EOB or denial letter to see the code and description of the issue.
🔍 Tip:
Double-check that all patient and procedure details match the initial claim.
Step 2: Collect All Supporting Documents
You’ll need to resubmit the original claim along with the following:
- Clinical notes or progress reports
- Operative or procedure notes
- Any previous communication with the payer

Step 3: Draft a Clear Appeal Letter
A formal letter must accompany your appeal. It should explain the medical necessity and correct any errors. (We’ll show you how to write this in the next section.)
Step 4: Submit the Appeal Properly
Different payers have different submission methods:
- Fax
- Secure portal upload
Follow the instructions precisely, or your appeal may not be accepted.
Step 5: Track the Appeal
Document the date of submission, payer rep name, confirmation number, and expected turnaround time. Use your billing software or RCM partner to automate reminders.
