Hi,
I would suggest to go for family option ( married spouse +2 children ; Unmarried - Father and Mother).
If your company is not going to pay premium how you are going to manage it under corporate scheme. Please formulate policy first and work on possible questions from employees.
What if employee resign in the middle of year after paying premium? Will the employee continue to get mediclaim facility or not? If not whether the premium paid will be reversed back to him on pro rate basis? Will the insurance company make the payment through employer and directly to the beneficiary (employee). In case of any claim dispute between employee and Insurance company who will mediate ?
In the absence of employer contribution it would be tough to handle it under corporate scheme. So please plan and execute properly.
