Dependents Under National Health Insurance in South Korea
Dependents Under National Health Insurance in South Korea
Introduction
South Korea’s National Health Insurance (NHI) system allows eligible family members to receive healthcare benefits through a registered insured person. These family members are known as dependents and can access medical services under the NHI system without paying separate insurance premiums in many situations.
For employees, foreign residents, and families living in South Korea, understanding how dependents work under National Health Insurance is important for managing healthcare costs. Spouses, children, and certain family members may qualify if they meet specific requirements related to family relationships, income, residency, and eligibility rules.
The dependent system is especially useful for families where one person has workplace-based health insurance and other family members do not have their own insurance status.
This guide explains dependents under National Health Insurance in South Korea, including eligibility requirements, registration procedures, healthcare benefits, foreign resident considerations, and common mistakes to avoid.
Understanding Dependents Under Korean NHI
What Is an NHI Dependent?
An NHI dependent is a family member who receives healthcare benefits through another person’s National Health Insurance enrollment.
The insured person who provides coverage is usually called the primary subscriber or insured person, while eligible family members are registered as dependents.
Dependents can use covered healthcare services, including:
- Doctor consultations
- Hospital treatment
- Prescription medications
- Preventive health screenings when eligible
How Dependents Differ From Individual Subscribers
Not everyone living in Korea needs to pay separate NHI premiums.
A person may qualify as a dependent if they meet specific requirements.
The main difference:
Individual subscriber:
- Pays their own NHI premiums
- Has independent insurance status
Dependent:
- Receives coverage through another insured person
- Usually does not pay separate monthly premiums
Who Can Become a Dependent Under Korean NHI?
Spouses
A spouse may qualify as an NHI dependent if they meet eligibility conditions.
This can include:
- Korean spouses
- Foreign spouses residing in Korea
- Spouses without independent insurance coverage
The National Health Insurance Service reviews factors such as income and residency status.
Children
Children may qualify as dependents under certain conditions.
Eligible family members may include:
- Biological children

Healthcare Costs for NHI Dependents

In many cases, registered dependents do not pay separate monthly NHI premiums.
However, eligibility depends on official requirements.
A person who no longer qualifies as a dependent may need to enroll independently.
Do Dependents Pay Medical Fees?

Dependents usually pay:

The payment structure is generally the same as other NHI users.

If a dependent starts working and becomes eligible for workplace insurance, their status may change.

- Regional subscriber
Changes in Income
If a dependent’s income exceeds eligibility limits, they may lose dependent status.
They may then need to register independently.
Changes in Family Situation
Changes such as:
- Divorce
- Marriage
- Death of the insured person
- Relocation outside Korea
may affect dependent eligibility.
