When local residents covered under the National Health Insurance program visit a doctor, the system covers most of the medical expenses, but patients are required to pay a small portion of the cost, called a "co-payment." The main reason for requiring a co-payment is to remind the insured that medical resources are used to help people who are ill or injured and should not be wasted under any circumstance.

In general, outpatients must pay a basic outpatient co-payment and a medication co-payment. If an outpatient was given rehabilitation therapy or traditional Chinese medicine therapy, then there will be an outpatient rehabilitation (including traditional Chinese medicine traumatology) co-payment. If a patient is hospitalized, then he or she will have to pay an inpatient co-payment when discharged.

  • Individuals classified as disabled pay co-payments of NT$50 for any medical care, regardless of the type of medical institutions they visit.
  • Patients who return for their first checkup after an outpatient or emergency procedure, or within 30 days after being discharged from the hospital, or within 42 days after giving birth, pay the same co-payment as if they were given a referral as long as they have a hospital certificate confirming the need for a follow-up visit.

3.Rehabilitation and Traditional Chinese Medicine Copayments
If you receive physical therapy or traditional Chinese medicine therapy for injuries (including traditional Chinese medicine traumatology) on an outpatient basis, the Co-payment for follow-up visits is uniformly NT$50 (except for "moderate to complicated" and "complicated" therapies).
4.Coinsurance for Inpatient Care
If a patient is hospitalized in a NHI-contracted hospital, the coinsurance rate -- the percentage of the overall cost of the stay to be covered by the patient -- depends on the type of the ward (acute or chronic) and length of stay, as shown in the following table:
Ward Coinsurance Rates
5% 10% 20% 30%
Acute - 30 days or less 31-60 days 61 days or more
Chronic 30 days or less 31-90 days 91-180 days 181 days or more
Coinsurance for multiple acute ward stays of fewer than 30 days and chronic ward stays of fewer than 180 days for the same ailment are capped, with the ceilings adjusted annually. For example, in the period from January 1, 2022 to December 31, 2022, caps on hospital stay coinsurance for acute ward stays totaling fewer than 30 days or chronic ward stays of fewer than 180 days during the year have been set at NT$43,000 for a single hospital stay for a particular condition, and at a cumulative NT$72,000 for the entire calendar year. Those who pay more than the established ceiling can apply for a reimbursement before the end of June of the following year.
(Note: The National Health Insurance Administration announces coinsurance ceiling on ward stay every year.)
Applying for a refund
  • Patients should fill out an "Instructions for NHI Prepaid Medical Expense Refund Application Form" and prepare copies of their medical receipts and itemized expenses. These should be filed at the National Health Insurance office closest to the hospital where treatment was initially sought.
  • You can go to an NHIA office or the NHIA website to download an application form.
