Sure @Christel Dsouza . As a result of surveying many top (model) employers we came to the conclusion that the very top of the line offering to employee on insurance benefit is by large companies like TCS ( 5 lakh insurance of self spouse and kids, with the option to add parents at own expense, TCS allows for top up of cover over and above 5 lacs if unfortunately someone has to utilise full 5 lacs) most employers will go for GMC of 5 lacs with maternity benefit, covering parents from company side is very expensive so we may allow employees to add parents at own expense ( that too insurance companies need a minimum number). Most companies go for a 3 lacs cover ( self spouse and kids). Many employees came up with queries like can I insure fiancé if I am single, can I add my in laws etc so be prepared for huge queries.
As to provider my personal experience with Star was very good in terms of basic actual insurance cover and claim settlement. We have also used Pazcare which provides a lot more frills and good dashboard but insurance side they are one level less than Star. If you would like to go with Loop which is trending in a big way, I can put you in direct contact with them.
Hope this helps.
