Columbia Asia Hospital — irresponsibility of the hospital insurance helpdesk team

My brother got admitted for his diabetic issue but while sending the details to the insurance company they mentioned bronchitis. While the entire treatment was for diabetic ketoacidosis because of this grave mistake the insurance company rejected the claim stating that bronchitis is not disclosed hence under non-disclosure part the claim is rejected. Even after sending the clarification letter from the doctor the claims were not honored for cashless.

The issue here was that the insurance helpdesk team in columbia asia yeshwanthpur referral hospital decided on their own regarding the complaint, on top of it they keep asking us to contact insurance company to clarify any queries. They are very curt & display irresponsible behavior.
