Vijaya Hospital — Unauthorized and uninformed treatment charges

Address:

Vadapalani, Chennai - 600 026

Admitted my mother in Vijaya Hospital on 15th March for Vascular related treatment.
Angio was done to determine the blocks and further treatment was recommended by the Doctor.
We are using insurance for payment and the hospital has told us an estimate of 2.5L and 3L for the treatment and also sent a pre-auth to my insurance company for only 2.5L and received an approval for 1.8L.
Further treatment recommended by the Doctor was stenting in Kidney and Leg. We were made to wait for 3 days for the Stent to come and after multiple follow-ups the treatment was done and stenting was completed. However the final billing came to 6.5L to all of our surprise and we were not informed about the increase in the billing at any time even after us asking multiple times during the course of the treatment.
Also no pre-auth approval for the increased bill estimate was not taken by the hospital after the initial request of 2.5L.
So we were in no idea that the bill amount would come to 6.5L. Now we have been pressurized by the hospital to pay a sum of 2.9L which is remaining after the insurance payment of 3.3L.
