Hi Vijay,
At the time of filing your return, claim the medical reimburement exemption for 15000 under Section 10. You are not allowed to submit any additional attachements at the time of filing your return so you cannot submit the supportings at the time of filing.
If at the time of assessment(s) you are called to produce bills for the above, you may do so.
Just for your information these re-imbursement would most likely be shown as ex-gratia in your Form 16 or pay-slip(s) since you have not submitted supportings for the same. Had you done so, they would never be shown in either your pay-slip(s) or Form 16 as these re-imbursements are exempted upto 15000 under Section 10 i.e. they are not considered as your income at all so there would be no question of taxing it. It has been taxed in your case because you have not submitted the supportings in time. Anyways, file your return as pointed earlier and things should be through. Please note that the supportings should all be dated between 01 April 2011 to 31 March 2012 only (assuming you are talking of the year ended 31 March 2012).
Also, medical re-imburesments are different from medical allowances. The latter is fully taxable. The former is not taxed to the extent it is backed by supportings.
Cheers and regards.
