India has a vast healthcare system that is organized into three levels - central, state, and district. At the central level, the key organizations are the Ministry of Health and Family Welfare, Directorate General of Health Services, and Central Council of Health and Family Welfare. States have significant independence in healthcare delivery and each has its own system. The central government focuses on policymaking, planning, and coordination between states. Districts are further divided into subdivisions, tehsils/talukas, villages, and municipalities/corporations for local administration.
