Your health insurance company may refuse to pay for or authorize a certain service or treatment. If so, your health insurance company will send you a denial notice or explanation of benefits form explaining why the health insurance company refuses to pay or authorize.
Before requesting an external review, you must ask your health insurance company directly to reconsider this decision though an internal appeal. Your health insurance company should explain how to submit an internal appeal. See here for more information on internal appeals.
If your health insurance company still refuses to pay for or authorize the treatment or service by issuing a final adverse determination letter following the internal appeal, you may be able to request an external review of that decision through the Office of Patient Protection.
