National Health Insurance

All individuals, except those who are enrolled in their workplace health insurance or are receiving welfare assistance, must join the National Health Insurance.

• For those with a My Number Health Insurance Card, an "Eligibility Information Notice (A4)" is provided. (The insurer information in the My Number Card will be automatically updated the day after the eligibility notification is submitted.)
• For those without a My Number Card or who have not registered it as their health insurance card, an "Eligibility Certificate (Paper Card type)" will be issued.
• When receiving medical treatment, always present your My Number Health Insurance Card or NHI Eligibility Certificate at the medical institution's counter.
• Additionally, individuals aged 75 and older (or those aged 65 and older who are certified as disabled) will receive medical care through the Elderly Medical Care System.

When receiving treatment for illness or injury, 70% or 80% of the medical expenses will be covered according to the burden category (you will be responsible for the remaining 30% or 20%).
Other benefits include medical expenses, high-cost medical treatment benefits, high-level nursing care combined medical expenses, childbirth lump-sum benefits, and funeral expenses.

Please report any changes within 14 days of occurrence.
If you are enrolled in National Health Insurance, please bring your My Number Health Insurance Card or National Health Insurance Eligibility Certificate.
For foreigners, a residence card is also required.

If you are injured in a traffic accident, the responsible party is usually required to pay for your treatment. You can receive treatment under NHI, but the insurance will later claim the costs from the responsible party. If using NHI for treatment, you must report the accident.
