Income tax exemption

I had a mediclaim policy which covered my whole family.As it was a corporate group policy so there were some additional benifits like meternity upto Rs. 25000/50000 and new born baby covered from day one . But when My new born baby was admitted in same hospital after 4 months later , TPA denied my all claims as baby is not enrolled under this policy . So I requested my employer to resolve this issue ASAP and I got the cheque for the same . Now my employer has included this ammount in my taxable income but  it is not any additionl income to me . it is the ammount that was paid by me to hospital and that suppose to be credited  credited to hospital becase of cashless hosptilisation under medical insurace then.

So how can I ask for tax execption.................

Help Me 

Thanks
