Ask for an Independent Medical Review (IMR)


If your health plan denies your request for medical services or treatment, you can file a complaint (grievance) with your plan. If you disagree with your plan's decision, you can ask the Help Center for an Independent Medical Review (IMR). An IMR is a review of your case by doctors who are not part of your health plan. If the IMR is decided in your favor, your plan must give you the service or treatment you requested. You pay no costs for an IMR.

You Can Apply for an IMR if Your Health Plan:

  • Denies, changes, or delays a service or treatment because the plan determines it is not medically necessary.
  • Will not cover an experimental or investigational treatment for a serious medical condition.
  • Will not pay for emergency or urgent medical services that you have already received.

Before You Apply

In most cases, you must complete your health plan's complaint process before you apply for an IMR. Your plan must give you a decision within 30 days or within 3 days if your problem is an immediate and serious threat to your health.

If your plan denied your treatment because it was experimental/ investigational, you do not have to take part in your plan's complaint process before you apply for an IMR.

You must apply for an IMR within 6 months after your health plan sends you a written decision about your complaint.
