Medical Allowance - Benifits

Hi friends,
Could any of you detailly explain me about medical allowance - the insurance policy the company takes to its employer.
I'm interested to know how these medical insurance policy taken by company works.What are the benefits an individual gets, what is the limit,eligibility for income tax, how to show them for tax exemption, How the networking hospitals work etc.,
Kindly provide me some inputs reg. this.

Dear,
The medical insurance scheme offered by Company has different benefita depending upon which kind of insurance the organisation has selected.
The employee gets all the facilities such as, cash list facility, hospitalisation, other ailments which requires hospitalisation, old ailments are also covered by some companies etc.
You can contact various brokers, such as ICICI prudential, Paramaount Health services etc these companies provide Medical Insurance for employees.
The premium paidis paid by the organisation so the employee do not get any Income tax benefit out of it(Im not 100% sure of it, but most likely it is the case).
I hope I have answered the query, in case of any further information please feel free to contact.
Cheers!!
