For planned care in Korea without Korean National Health Insurance (NHIS), ask the provider for an estimate for the particular consultation, assessment, or treatment being discussed. Explain whether you expect to pay yourself or use private insurance. Ask what the estimate includes, which charges are still uncertain, and when payment is due. If you pay in advance, ask how the hospital will settle any difference between that payment and the final bill.
Explain whether you have private insurance or will pay yourself
Tell the hospital whether you plan to use private insurance or pay yourself. Not using NHIS alone does not answer that question.
Samsung Medical Center’s billing guide describes direct billing involving contracted insurers and a guarantee of payment. If that guarantee has not arrived, its guidance says patients need to pay upfront and make their own claim. Ask your insurer whether it will reimburse the proposed care; the hospital’s billing procedure alone does not confirm this.
SNUH’s billing guide also describes insurer-specific arrangements. Check the applicable process with both the receiving provider and your insurer rather than treating an insurance card as confirmation of cashless billing.
If you will pay yourself, say so directly. Ask whether the information available is enough for an estimate or whether the provider needs records or an assessment first.
Ask what the estimate includes and what is still unknown
Use a written reply to separate the proposed care from unconfirmed additions. This worksheet gives you questions to ask; it does not assume that every visit involves every item.
| Item to clarify | Reply to record |
|---|---|
| Consultation or initial assessment | What visit is being estimated and what it includes |
| Proposed tests or treatment | Which are included, separate, or not yet determined |
| Medicines and supplies | Whether the estimate includes them and where payment would be made |
| Certificates or record copies | Whether requested documents would involve separate charges |
| Review visits or further care | What is included and what would need another estimate |
| Advance payment | What is due, when, and how it will be applied to the final bill |
If an item cannot yet be priced, ask what information or clinical assessment is needed for an estimate. Keep these uncertain charges beside the quoted amount so you know which parts of the visit it covers.
Keep an estimate separate from the final bill
Samsung Medical Center’s self-pay inpatient guidance describes an estimate at the pre-admission consultation and states that the final bill may differ according to the treatment actually provided. This is an inpatient example at one hospital, not a fixed-price rule for outpatient care throughout Korea.
Ask your provider what could change its estimate and how changes would be explained. Keep the estimate’s date, the care being described, and any conditions with the quoted amount.
Advance payments need their own explanation. Asan Medical Center’s FAQ says that where actual medical charges are below the amount paid in advance, a refund is made after the account is finalized. Confirm your provider’s terms and settlement process for the payment being requested; do not assume the same arrangements apply everywhere.
Use this estimate-request template
Adapt the wording to the care you are enquiring about:
I am asking about [consultation / proposed assessment or treatment] and will not be using Korean NHIS. I expect to use [self-payment / private insurance]. Please let me know whether you can provide a written estimate from the information available.
Please separate consultation, proposed tests or treatment, medicines, documents, and any follow-up charges. Which items are included, separate, or still uncertain? Is an assessment or additional information needed to clarify the cost? Please also explain any advance payment, what could change the estimate, and how final charges are settled.
For the first contact and record-submission process, use the hospital appointment enquiry guide. If a procedure is proposed, the procedure consultation questions cover the clinical decision alongside the cost discussion.
Once you receive payment documents, use the guide to receipts, itemized charges, and medication costs to organize what has been charged and paid.
This guide helps you request cost information. It does not quote a treatment price or determine insurance coverage or reimbursement.
