Star Health And Allied Insurance — denial of insurance claim

Address: Dakshina Kannada, Karnataka, 575004

Policy availed in january 2016. No claims made until now. Now, when we claim for treatment of my wife, they are demanding discharge summary of december 2016 of our different hospital. For not providing that, they have denied cashless claim. Also, they threaten, reimbursement claim will be rejected, if the same details are not provided. Am i supposed to be sharing personal health reports with insurance companies who have not provided financial help.
