My insurance denied two claims. I appealed it and they denied my appeal. I received a letter letting me know I can request an external appeal through my employer. I submitted a letter, signed doctor's letter of medical necessity, signed medical records release form and a few clinical studies showing effectiveness of treatment. I received a letter in the mail today from Network Medical Review Co. The letter states: NMR has received a request for external review and has been notified from the plan that the request is eligible. NMR has accepted the request for external review. You, the claimant, may submit in writing to NMR, within 10 business days following the date of receipt of this notice, any additional information that you wish NMR to consider in reviewing your claim. NMR will review all of the information and documents timely received, and will provide written notice within 45 days after NMR receives the request for the external review. I'm not sure if my employer would send everything that was sent to them or if I have to send everything all over again. I sent them the original doctors letter of medical necessity so all I have is a copy.
