New India Assurance — Unjustified Deductions from Hospital Bill.

My Hospital Bill was Rs. 36, 907/-. I was reimbursed Rs. 30, 033/-. The unjustified deductions were Rs. 700/- for Blood sugar tests by Glucometer. Reason given, Chart not available. I provided the Hosptal Chart. There were deductions worth Rs.3750/- from Investigations. Reason Investigation not related to primary ailment. The tests are like COVID, HIV etc. But these are mandatory tests for any admitted patient.
I may agree to balance deductions but I pointed out these unjustified deductions. I had sent the covring letter along with post Hospital reimbursement and attached the Glusometer chart and mentioned the mandatory tests conducted by Hospital.
