RSBY is a health insurance scheme in India that provides cashless insurance coverage of Rs. 30,000 per year for hospitalization to below poverty line families. It was launched in 2008 to provide health insurance to families not covered by other government schemes. The scheme uses smart cards and is funded jointly by the central and state governments. It aims to empower beneficiaries and provide a business model for various stakeholders like insurers, hospitals, and intermediaries. However, there are some shortcomings like unnecessary treatment, lack of primary care coverage, and not accounting for state-specific health needs.
