A Family Health Insurance Plan is a comprehensive health insurance policy designed to provide medical coverage for an entire family under a single plan. It typically includes benefits such as hospitalization, maternity coverage, daycare procedures, and preventive health check-ups. Premiums are based on the coverage amount (sum insured) and the number of family members included, which often cover spouses, children, and sometimes dependent parents. Family plans are cost-effective compared to individual policies and offer the convenience of a shared sum insured, ensuring financial protection against unexpected medical expenses.
