Medical Certificate Korea English: Everything International Patients Need to Know
Whether you’re a foreign resident, a tourist who fell ill, or an international patient visiting Korea for elective treatment, obtaining a medical certificate in Korea in English is often a critical step. You may need it for insurance reimbursement, visa applications, employer documentation, or returning to your home country. This comprehensive guide walks you through exactly how to get one, what it costs, and what to watch out for.
What Is a Medical Certificate in Korea?
A medical certificate (진단서, jindanseo) is an official document issued by a licensed Korean physician confirming a patient’s diagnosis, treatment history, hospitalization period, or fitness for travel. In Korea, these documents carry legal weight and must be stamped with the issuing doctor’s seal and the hospital’s official stamp to be considered valid.
For international patients, the key distinction is whether the document is issued in Korean only or in English (or bilingual format). Most major hospitals in Seoul and other large cities can issue English-language or bilingual medical certificates on request, but smaller clinics may only provide Korean versions that require certified translation.
Types of Medical Certificates Available
- 진단서 (Diagnosis Certificate): States your medical diagnosis and condition.
- 소견서 (Medical Opinion Letter / Referral): A doctor’s professional opinion, often used for referrals or insurance.
- 입퇴원확인서 (Hospitalization/Discharge Certificate): Confirms admission and discharge dates.
- 건강진단서 (Health Certificate): A general health check certificate, often needed for visas or employment.
- 상해진단서 (Injury Certificate): Used in legal or insurance cases involving physical injury.
Why International Patients Need an English Medical Certificate
According to the Korea Health Industry Development Institute (KHIDI), over 600,000 foreign patients visited Korean medical institutions in 2023 alone. With this volume of international visitors, the demand for English-language documentation has grown significantly. Common reasons foreigners request an English medical certificate in Korea include:
- Filing claims with international travel or health insurance providers
- Providing documentation to employers or universities abroad
- Applying for or extending a medical visa (D-1 or C-3 visa)
- Proving medical necessity for flight accommodations or boarding assistance
- Legal proceedings in their home country
Dr. Kim Sung-hee, an international patient coordinator at a major Seoul university hospital, notes: “We see a significant number of foreign patients who don’t realize until discharge that they need English documentation. We always recommend requesting it at the time of registration or treatment to avoid delays.”
Where to Get a Medical Certificate in English in Korea
1. University Hospitals (대학병원)
Large university hospitals such as Seoul National University Hospital, Yonsei Severance Hospital, Samsung Medical Center, and Asan Medical Center all have dedicated international patient centers. These centers routinely issue bilingual or English-only medical certificates. They typically have English-speaking staff and streamlined processes for foreign patients.
2. International Clinics in Seoul
Clinics specifically catering to expats and foreign visitors — particularly in areas like Itaewon, Gangnam, and Mapo — are experienced in issuing English medical certificates. Many advertise English-language services prominently. Examples include the Seoul Global Center’s partner clinics and internationally certified health centers.
3. General Hospitals and Community Clinics
Smaller clinics (의원) may only issue documents in Korean. In this case, you have two options: request a certified translation through the hospital’s administrative office (if available), or hire an external certified translator. The Korean Medical Association recommends using a NAATI-certified or court-certified translator for documents submitted to foreign governments or legal bodies.
How to Request a Medical Certificate in Korea: Step-by-Step
- Register at the hospital: Bring your passport (and Alien Registration Card if you have one). Clearly state at registration that you are a foreign national and may need English documentation.
- See your doctor: Communicate your full medical history. Mention at the beginning or end of the consultation that you need an official medical certificate.
- Request the certificate at the administrative desk: After your consultation, visit the medical records or documentation office. Specify that you need the certificate in English or bilingual format.
- Pay the issuance fee: Fees are charged separately from your consultation fee (see cost breakdown below).
- Receive and verify the document: Check that the document includes the doctor’s name, license number, official hospital stamp, and the date of issue.
Cost of a Medical Certificate in Korea
The cost of obtaining a medical certificate varies by document type and institution. Below is a general price range based on current 2026 data:

Tips for Getting Your English Medical Certificate Smoothly
Communicate Early
Always mention at the start of your visit — not at the end — that you need an English certificate. This gives the physician and administrative staff time to prepare properly formatted documentation.
Bring Proper Identification
Korean hospitals require government-issued photo ID for official document requests. A passport is universally accepted. Your Alien Registration Card (ARC) is also helpful if you’re a resident.
Check for Apostille if Needed
If you need the document for legal use in another country, you may require an Apostille. Korea joined the Hague Apostille Convention. You can obtain an Apostille from the Ministry of Foreign Affairs or local district offices for an additional fee of approximately ₩1,000 per document (around $0.80 USD), though notarization or additional steps may cost more depending on the use.
Keep Copies
Always request at least two certified copies. Medical certificates are official documents and cannot always be reprinted without another fee or a new doctor’s visit.
Medical Certificate for Insurance Claims: What to Include
International insurance companies (including travel insurance providers) typically require your English medical certificate to contain: the patient’s full name and date of birth, dates of treatment or hospitalization, the specific diagnosis using ICD codes if possible, the treating physician’s name and license number, and the official hospital stamp. If your document is missing any of these, ask the administrative staff to include them before you leave.

Frequently Asked Questions (FAQ)
Q1: Can any Korean clinic issue an English medical certificate?
Not all clinics have the capability to issue certificates in English. Smaller local clinics (의원) typically issue documents in Korean only. For guaranteed English documentation, visit a university hospital’s international center or a clinic that explicitly offers English-language medical services.
Q2: How long does it take to receive a medical certificate in Korea?
At most hospitals, a standard diagnosis certificate can be issued the same day after your consultation, often within 30–60 minutes. More complex documents like injury certificates may take 1–3 business days as they require additional physician review.
Q3: Is a Korean medical certificate accepted by foreign insurance companies?
Yes, in most cases. English-language medical certificates from Korean licensed hospitals are widely accepted by international insurers. Some insurers may request an Apostille for legal verification. Always check your specific insurer’s requirements before your visit.
Q4: What if my medical certificate is only in Korean?
You can request a certified translation through the hospital (if offered) or through a licensed translation agency in Korea. For documents submitted to foreign courts or governments, ensure the translator is certified. Costs typically range from ₩20,000 to ₩80,000 ($15–$61 USD) depending on document length and complexity.
Q5: Do I need a medical certificate to extend my stay in Korea for medical reasons?
Yes. If you are applying for a visa extension on medical grounds (such as under a C-3 or D-1 medical visa), the Korean Immigration Service requires an official medical certificate from a licensed Korean healthcare institution explaining your diagnosis and the necessity of continued treatment. The document must be in Korean, but you may also include an English version for your personal records.
