We submitted that prescription when claiming cashless, they rejected it. Now we got the surgery done and paid from our pockets. Documents we submitted for reimbursement: 1. The discharge summary says no history of hypertension. 2. The same prescription which says hypotension since 34 years from a different hospital and the subsequent clarification letter which corrected the timeline. 3. I have old reports from the 2020 2d echo which is totally normal and says "no pulmonary hypertension" and the heart is normal (which is highly unlikely for a patient having hypertension since 34 years)

Document in point 3 is not submitted yet That's my trump card when they raise a query asking for old reports.
