  • Managing the eligibility of the insured
  • Collecting Insurance Contribution

The Health Insurance Review & Assessment Service (HIRA) evaluates the medical service fee, quality of health care, and adequacy of medical service.

All Koreans except those belonging to the lower-income group enroll to the compulsory health insurance. Healthcare providers may not refuse to treat NHI patients, and all enrollees should pay the contributions monthly.
