Healthcare System Overview

South Korea operates a universal single-payer system through the National Health Insurance Service (NHIS), covering over 97% of the population. Enrollment is mandatory for all citizens and registered foreigners, funded by contributions from employees, employers, and the government. Private health insurance is supplementary, covering co-payments, non-covered services (dental, vision, alternative medicine), and reducing catastrophic out-of-pocket expenses.
