Appealing a health plan decision

External Review

There are 2 steps in the external review process:
  1. You file an external review: You must file a written request for an external review within four months after the date you receive a notice or final determination from your insurer that your claim has been denied.
  2. External reviewer issues a final decision: An external review either upholds your insurer’s decision or decides in your favor. Your insurer is required by law to accept the external reviewer’s decision.

Types of denials that can go to external review

  • Any denial that involves medical judgment where you or your provider may disagree with the health insurance plan
  • Any denial that involves a determination that a treatment is experimental or investigational
  • Cancellation of coverage based on your insurer’s claim that you gave false or incomplete information when you applied for coverage

What are my rights in an external review?

Insurance companies in all states must offer an external review process that meets the federal consumer protection standards.
State: Your state may have an external review process that meets or goes beyond these standards. If so, insurance companies in your state will follow your state’s external review processes. You’ll get all the protections outlined in that process.
Federal: If your state doesn’t have an external review process that meets the minimum consumer protection standards, the federal government’s Department of Health and Human Services (HHS) will oversee an external review process for health insurance companies in your state.
Depending on your plan and where you live, the following may apply to you:
  • In states where the federal government oversees the process, insurance companies may choose to participate in an HHS-administered process or contract with independent review organizations.
  • If your plan doesn’t participate in a state or HHS-Administered Federal External Review Process, your health plan must contract with an independent review organization.

How do I learn more about my state’s external review?

  • Look at the information on your Explanation of Benefits (EOB) or on the final denial of the internal appeal by your health plan. It’ll give you the contact information for the organization that will handle your external review.
  • See this state list maintained by the HHS’s Center for Consumer Information & Insurance Oversight.
