Overseas & International Health Insurance

International residents, expatriates, business travelers, and medical travelers may have private health insurance issued outside Korea.

Whether overseas insurance can be used for treatment in Korea depends on the insurance policy, insurer, hospital, and type of medical care.

CHECK YOUR COVERAGE FIRST

Before planned treatment, contact your insurer and confirm:

• Whether treatment in Korea is covered
• Coverage limits
• Deductibles or patient contributions
• Excluded treatments
• Pre-authorization requirements
• Hospital network requirements
• Claim procedures
• Required medical documents

Do not assume that worldwide coverage means every treatment in Korea is covered.

DIRECT BILLING

Some international insurance arrangements may allow a hospital to communicate directly with an insurer.

However, direct billing is not guaranteed.

Depending on the hospital and insurer, patients may instead need to:

Receive Treatment → Pay Hospital → Collect Documents → Submit Claim → Request Reimbursement

Confirm the procedure before planned treatment whenever possible.

PRE-AUTHORIZATION

Some insurance policies require approval before:

• Hospitalization
• Surgery
• Expensive diagnostic tests
• Certain specialist treatments
• Other high-cost medical services

If pre-authorization is required, obtain it according to your insurer's procedures.

INTERNATIONAL PATIENT CENTERS

Major Korean hospitals with international patient centers may be able to assist with insurance-related administrative procedures.

However, available services and insurer relationships vary by institution.

Before treatment, ask:

Does the hospital work with my insurer?

Is direct billing available?

What documents should I provide?

PLANNED MEDICAL TRAVEL

People traveling specifically to Korea for medical treatment should pay particular attention to insurance exclusions.

Some international health policies may distinguish between unexpected healthcare needs and elective or pre-planned treatment abroad.

Verify coverage directly with the insurer before arranging travel.

DOCUMENTS FOR REIMBURSEMENT

Depending on the insurer, documents may include:

• Receipt
• Itemized medical bill
• Medical certificate
• Diagnosis information
• Treatment report
• Prescription
• Examination results
• Proof of payment

The insurer determines the exact documentation required.
