What are the requirements for a foreign health insurance policy to qualify for exemption from Korea's National Health Insurance (NHIS)?

This is a common question for Working Holiday visa holders. To qualify for NHIS exemption, your private insurance must cover the same scope as NHIS, which means it needs to include hospitalization, outpatient care, and prescription drugs in Korea. The policy must be valid for the entire duration of your stay and issued by an insurer recognized by the Korean government.

In practice, getting the exemption approved can be tricky. You need to submit your insurance policy details to the local NHIS branch and they will review whether it meets the minimum coverage requirements. Some people report being denied even with comprehensive private insurance because the NHIS office interpreted the requirements strictly. If you are on a Working Holiday visa (H-1), you are required to have private insurance anyway for the visa application, but that does not automatically exempt you from NHIS once you register as a resident. My suggestion is to visit your local NHIS office with your insurance policy translated into Korean and ask them to review it before assuming you are exempt. If the exemption is denied, NHIS premiums for Working Holiday visa holders are around 130,000 won per month.
