Understanding Your Appeal Rights
When your insurance claim is denied, you have the legal right to appeal that decision. In fact, research shows that many denials are overturned on appeal — estimates suggest 40-60% of appeals are successful when proper documentation is provided. Understanding your appeal rights is the first step to fighting back.
Your appeal rights depend on your type of coverage. Employer-sponsored plans are governed by ERISA (Employee Retirement Income Security Act), Medicare denials follow federal Medicare rules, and Medicaid appeals are state-specific. Private individual plans follow state insurance regulations. Regardless of your coverage type, you have the right to request reconsideration of a denial.
The Two-Level Appeal Process
Level 1: Internal Appeal is your first step. Within 30-60 days of receiving your denial notice (timelines vary by plan and state), submit a written appeal to your insurance company. Your appeal should include: (1) your denial notice, (2) additional medical evidence or documentation that supports the need for treatment, (3) a clear written explanation of why you believe the denial was incorrect, and (4) any supporting letters from your healthcare provider.
Level 2: External Review is available if your internal appeal is denied. Request an independent review by a physician or medical professional who was not involved in the initial denial decision. The external reviewer evaluates your case independently and can overrule the insurer's decision. External reviews typically take 30-45 days.
Gathering Documentation for Your Appeal
Strong documentation is critical to appeal success. Gather: your complete medical records relevant to the denied procedure, progress notes from your healthcare provider, test results or imaging that supports the medical need, clinical guidelines or peer-reviewed literature supporting the necessity of the treatment, and letters of medical necessity from your treating physician.
Your healthcare provider is your strongest ally in an appeal. Ask them to write a letter specifically addressing why they believe the treatment is medically necessary and why it cannot be delayed or substituted with an alternative. Specific clinical details matter far more than generic statements.
Writing Your Appeal Letter
Your appeal letter should be clear, concise, and professional. Start with your policy number and the specific claim being appealed. Explain why you believe the denial was wrong, referencing the specific reason given in the denial notice. Use clinical language and cite medical guidelines if applicable. Conclude with a clear request for reconsideration and reversal of the denial.
Avoid emotional language or attacks on the insurance company. Insurance reviewers respond better to well-documented clinical arguments than to complaints. Your goal is to make a compelling case based on evidence, not emotion.
