New India Assurance — medical bills as non medical expense and assistant surgeon charges deducted

Hi,
I have submitted my claim for my father's hernia surgery.
I submitted all medical bills and discharge summary everything.
They have rejected the medical bills (Including medicines needed for surgery) as non medical expense.

And in discharge summary assistant surgeon fees mentioned. They rejected that also. Everything covered under hospitalization/surgery expense.
I cannot say that assistant surgeon should not be in surgery.in every surgery assistant surgeon will be there. Single surgeon cannot take care of everything

If any additional documents needed to prove the above expense during hospitalization and must needed medicines, i am ready to submit from my end

They deducted copay also.

After the above deduction, 50 % of the amount only i am able to claim.

For emergency situation only i go with claim option. Cashless means hospital will care of everything. I feel frustrated with claim option.

When i reached customer care, they have not responded properly. They are repeating the same. Hospitalization expense should cover under the policy

Kindly do the needful.
