Address:	Maharaja Agrasen Hospital West Punjabi Bagh, New Delhi – 110026, New Delhi, Delhi, 110026

My mother got admitted in Maharaja Agrasen Hospital, Punjabi bagh in March 2019. We have availed mediclaim from United India Insurancee, Raksha Tpa(3rd party). But on her discharge Rs. 8000/- we not returned to us stating the reason as the CTScan was not cashed by Raksha TPA as their doctors treated that CT Scan to be irrelevant to the disease my mother was suffering from.
The doctor in Agrasen hospital provided information stating the reason for the test. Still the tpa guys were not convinced.
Now I am stuck in between hospital and Raksha TPA for Rs 8000/-. They are just blaming each other but not taking responsibility. In this case we as a customer find ourselves in a situation where we don't know what action to take. I don't know if the money should come from Raksha Tpa or Maharaja Agrasen Hospital but we are suffering a lot. Earlier my mother suffered due to her illness, after that I suffered for getting that Rs.8000/- back.
