I am the customer of Royal Sundaram Health Insurance for the last ten years. I have good expedience with the dealing with the company. It has good net work of private hospitals. The cash less treatment is very simple. Just give the copy of your health card and the treatment will start without paying any amount. Two times I have been treated with this card as cashless treatment. Post operation expenses for 60 days is also paid. It has also a scheme called Hospital Benefits in which on admission in hospital you are paid per day Rs. 1000/- Rs. 500000/- insurance. I appreciate This Health Insurance a lot.
