India has several government health insurance schemes and companies that provide coverage. The choice of the ""best"" government health insurance company can depend on various factors such as your specific needs, location, and the features offered by different schemes. Here are some of the prominent government health insurance schemes in India:

Ayushman Bharat Pradhan Mantri Jan Arogya Yojana (AB-PMJAY): Launched by the Government of India, this scheme provides financial protection and health assurance to over 100 million poor and vulnerable families. It covers hospitalization expenses.

Central Government Health Scheme (CGHS): CGHS provides comprehensive healthcare facilities for Central Government employees and pensioners, as well as their dependents.

Rashtriya Swasthya Bima Yojana (RSBY): Although RSBY has been subsumed under the Ayushman Bharat scheme, some states may still be implementing their own versions. It aimed to provide health insurance coverage to below-poverty-line families.

State-specific health insurance schemes: Many states in India have their own health insurance schemes. For example, Aarogyasri in Andhra Pradesh and Telangana, Mukhyamantri Amrutum Yojana in Gujarat, and others.
