What to Do When Your Insurance Denies a Claim
Receiving an insurance denial can be overwhelming. But denials are not the final word — you have the right to appeal, and a significant percentage of appeals are successful. Here's exactly what to do.
Immediate Steps After Receiving a Denial
1. Don't Panic — and Don't Ignore It
Insurance denials are reversed more often than you think. Studies show that patients who appeal win roughly 40-60% of the time, depending on the type of denial.2. Read the Denial Letter Carefully
Your denial letter must include:- The specific reason for the denial
- The plan provision or clinical guideline used
- Your appeal rights and deadlines
- Contact information for filing an appeal
3. Understand the Denial Reason
Common denial reasons:- Not medically necessary: The insurer doesn't think you need the treatment
- Not covered: The service isn't in your plan
- Prior authorization required: You didn't get pre-approval
- Out of network: The provider isn't in your plan's network
- Experimental/investigational: The insurer considers the treatment unproven
4. Gather Your Evidence
- Medical records supporting the treatment
- Your doctor's recommendation letter
- Peer-reviewed studies showing effectiveness
- The insurer's own clinical guidelines (often available online)
- Any relevant state or federal laws
5. File Your Appeal
- Write a formal appeal letter
- Include all supporting documentation
- Send via certified mail (keep copies of everything)
- File within the deadline specified in your denial letter
6. Know Your Escalation Options
- Internal appeal → External review → State insurance commissioner → Legal action
