My Policy No.[protected], I had applied for Cash less pre-authotrization on 16/03/2019, my expected date of Admission was 19/03/2019. I was asked documents to process the claim . All the required documents, Reports etc which I had ( all I have nothing more) was submitted.
Investigation Reports was also submitted along with the history of ailment . . They kept on asking for revised estimate for conventional surgery as robotic surgery is not payable as per policy. Our Dr. Vinay Mahendra, specifically said that the surgery in a conventional way was dangerous for the patient, he even gave a written statement to the Insurance Co. letter is attached. Kindly see to the above . I have been going through a turmoil as now I have to arrange money on my own, I wonder why I have been paying premium all these years.
