Insurance Appeals Guide
A complete guide to understanding and navigating the insurance appeal process when your claim has been denied.
What is an Insurance Appeal?
An insurance appeal is your formal request for your health insurance company to reconsider a decision to deny payment for a medical service or treatment. Federal law (ERISA) and the Affordable Care Act give you the right to appeal any denial.
When Should You Appeal?
You should consider filing an appeal when:
- Your insurer denies coverage for a treatment your doctor recommended
- A service is deemed "not medically necessary" despite your physician's assessment
- Your claim is denied due to lack of prior authorization
- The insurer classifies your treatment as "experimental" or "investigational"
- You receive an "out-of-network" denial for emergency care
Types of Appeals
Internal Appeal (First Level)
This is your first formal request for the insurance company to review its decision. The review is conducted by someone at the insurance company who was not involved in the original denial decision.
Timeline: You typically have 180 days from the denial date to file an internal appeal.
External Review (Second Level)
If your internal appeal is denied, you have the right to request an external review by an independent third party not affiliated with your insurance company.
Binding Decision: The external reviewer's decision is final and binding on the insurance company in most cases.
What You Need to File an Appeal
- Denial Letter: Your official notice from the insurer explaining why the claim was denied
- Medical Records: Documentation supporting medical necessity
- Doctor's Letter: A statement from your treating physician explaining why the treatment is necessary
- Clinical Guidelines: Reference to medical literature or practice guidelines (if applicable)
- Policy Documents: Your insurance policy showing the relevant coverage provisions
Writing an Effective Appeal Letter
Your appeal letter should:
- Clearly state you are appealing the denial
- Reference your policy number and claim number
- Explain why the denial was incorrect based on medical facts and policy language
- Include supporting documentation
- Request a specific action (approval of the treatment)
- Be professional and factual (avoid emotional language)
Common Reasons for Denial
- Medical Necessity: Insurer claims the treatment is not medically necessary
- Prior Authorization: Required approval was not obtained before service
- Experimental/Investigational: Treatment is considered unproven
- Out-of-Network: Provider is not in the insurance network
- Policy Exclusions: Service is specifically excluded from coverage
