Some points to keep in mind:
- Do not buy family floater policy as your parent’s age will inflate the cost of the policy.
- Buy individual health policy for your parents
- You can check various online options but they seem to be expensive. Hence, I’d recommend that you approach public sector banks which offer Group Health Insurance to their customers at competitive rates. For example- IOB offers a decent health insurance policy for senior citizens in association with Apollo Munich Life Insurance. And this policy costs almost 1/3rd the price of their regular policy!
