Here is another article on Health Insurance. Apart from the usual medical insurance , popularly called Mediclaim , we have another new product in the market , which could be a ideal way to increase your cover http://www.apnainsurance.com/health-insurance-india/super-top-up.html
Especially those of us who already have medical insurance , either bought by our self or provided through our employer this is good way to enhance the amount of cover . And as earlier I would recommend that you buy a individual policy , instead of a family floater.
