Health insurance provides coverage for medical expenses and loss of earnings due to illness or injury. It depends on the conditions, benefits, and treatment options covered by the policy. Premiums are paid in advance for future health coverage. There are different types of health insurance plans such as group, individual, and family floater plans. While perceptions of health insurance in India are mixed, it has become necessary due to rising medical costs, the need to share health risks, and securing one's family's health. Government initiatives aim to increase health insurance penetration and affordability, but challenges remain around healthcare delivery and costs, consumer awareness, and claim ratios.
