Dear Vera,
Mediclaim is term which usually refer to an Insurance Policy which gives medical coverage to the member. It commonly has two systems:
1) Reimbursement of Medical and Hospital Expenditure upto the Specified Limits for all covered.
2) Cashless policy whereby you have to produce your Medical Insurance Cards to avail benefits.
The Mediclaim is not Taxable on the hand of the employee.
Medical Allowance is a type of allowance which forms a part of Salary and is paid at fixed interval of time (as decided) and has no connection with the expenses incurred on medical. This is usually taxable and tax relief is provided in case the employee files relevant documentary proof of medical expenditure.
The suitable Policy followed nowadays is reimbursement of Medical Expenditure. The employee is usually paid against Medical Expenditure incurred, and this amount becomes non taxable, if the employee wants he can simple ask and take the money without incurring any medical expenses but this amount becomes taxable.
Regards,
SC
