Respected sir,
My wife was admitted in astha multispecialty hospital at karjan for bacterial meningitis with saptimia on 21st april, 2019 at 11.25 pm.
Then she was referred by astha multispecialty hospital for m. R. I. Brain stroke protocol to vadodara. Mri brain stroke protocol was done by makarpura diagnostic vadodara on 22nd april, 2019 early morning at 2:45 am.
All the bills related to the treatment were handed over to national insurance ltd company. Now, i have received a letter from national insurance co. Ltd. Baroda do-i office, tilak road, vadodara-390001 stating that my claim is rejected under clause no. 5.1 (Misrepresentation, misdiscprition or non discloser of any material facts).
I have taken insurance with niicl for last 4 years from year 2014 to till the date. As my wife was admitted on 21st april, 2019 at 11:25 pm and immediately referred for mri and as soon as mri procedure completed she was again readmitted in the same hospital for further treatment. So there is no break even of time as it was the part of the treatment. How 5.1 there is misrepresentation, misdiscprition or non discloser of any material facts? There is no any past treatment as the dieses was occurred all of sudden on 21st april, 2019 at 11:25 pm.
So my case is absolute genuine and i am prejudice for rejection of mediclaim amount.in this situation where is the question of misrepresentation, misdiscprition or non discloser of any material facts? And for any query, any of our representatives may approach for clarification if required.
Please look into the matter and arrange to settle the claim at the earliest to avoid me to go through the consumer court.
Thanking you, your immediate attention is required.
