Insurance Regulatory and Development Authority, IRDA has proposed to make it mandatory for health insurers to provide policy cover to people up to 65 years and settle all claims within a month.In its draft guidelines for health insurance companies, the IRDA said that insurers will have to provide cashless facility to policy holders undergoing treatment in a particular hospital even after it is removed from the list of preferred service providers.The draft also talks about portability, under which a policy holder can migrate to another health insurance providing company, without losing any benefit.
