India's health insurance sector has become an important component of the nation's healthcare finance system by providing financial security against rising medical costs and increasing access to healthcare services. The sector has grown significantly due to a number of factors, including rising healthcare spending, public awareness, business sector participation, digitisation, and government initiatives.In order to guarantee orderly sector development, safeguard policyholders, bolster insurer accountability, and improve transparency, the Insurance Regulatory and Development Authority of India (IRDAI) has implemented a number of regulatory reforms in tandem with this expansion.With a focus on IRDAI's regulatory changes and transparency measures, this paper explores the expansion and evolution of health insurance in India. Policyholder protection, insurance product standardization, policy term disclosure, claims processing, portability, grievance redressal, digitization, and the Customer Information Sheet (CIS) are its main areas of emphasis. Additionally, the study evaluates how these actions can lessen information asymmetry and raise customer confidence and knowledge.Using secondary data from IRDAI reports, rules, circulars, government publications, and scholarly literature, the study takes a descriptive and analytical approach. According to the results, policyholder rights, accountability, standardization, and transparency have all improved as a result of regulatory reforms. Affordability, complicated policy constraints, disagreements pertaining to claims, low knowledge, and uneven rural penetration, however, continue to be major obstacles. The study comes to the conclusion that more openness, consumer education, streamlined disclosures, and stricter regulations are necessary for the inclusive and long-term expansion of health insurance in India.
