What: Odisha became the 34th state to implement Ayushman Bharat Pradhan Mantri Jan Arogya Yojana (AB PM-JAY), India’s flagship health insurance scheme providing ₹5 lakh annual health coverage per family for secondary and tertiary hospitalization. This expansion extends coverage to over 96 lakh additional families in Odisha, addressing healthcare affordability challenges and reducing out-of-pocket expenditure that pushes approximately 55 million Indians into poverty annually due to medical expenses.

How: Odisha integrated PM-JAY with its existing state health scheme to create a comprehensive universal health coverage model. Implementation involves empanelment of public and private hospitals, training healthcare workers on Ayushman Mitra roles, issuing biometric health cards, and establishing claim processing infrastructure. The scheme covers 1,949 medical and surgical packages including cancer treatment, cardiac surgery, and organ transplants, with cashless treatment at empaneled facilities through a paperless, technology-driven platform.
