I am glad for your decision to take health insurance cover. Health insurance covers the expenses of the diseases. This minimizes the financial burden of the insured person. However, to get the maximum benefit of the cover the application should have done prior to the illness.
Now that application for the insurance cover has been made, get the financial assistance by just paying the premium of the policy.

As your question is not specifying the query I am trying to discuss the maximum on health insurance that I know. Here are the various health insurance plans offered by insurance companies in India:
Hospitalization
Family floater health insurance:
Pre-existing disease cover plans
Senior citizen health insurance:
Maternity health insurance
Hospital daily cash benefit plans
Critical illness plans:
Pro-active plans
Disease-specific special plans
Top-up plans

If you havnt insured your other members of the family, do visit the online site eg. Policy Bazaar.com give the type of Insurance required, the amount of insurance, age, term etc with the top-up facility and get comparative quotes. Shortlist considering the claim settlement amount and the possible the discount factor.
