## Who qualifies for national screening in Korea?

National screening depends on insurance category and the annual NHIS target record; most general-screening groups follow a two-year cycle.

Office-worker designation and non-office-worker designation belong to employment records. The calculator does not infer your job category from a job title, nationality or age. A dependent and a household member normally need to meet the age 20 threshold; a self-employed household head has a different base age condition.

A matching birth-year parity is useful for the normal two-year pattern. It does not show whether an employer added you to the list, an earlier missed checkup was registered, or insurance status changed. The authenticated screening notice resolves those cases.

**General-screening base rules, 2026**

| Insurance category | Base condition | Interval |
| --- | --- | --- |
| Employee, office | Selected employee cohort; compare birth-year parity | 2 years |
| Employee, non-office | Every insured non-office worker | 1 year |
| Self-employed household head | Insured head of household | 2 years |
| Self-employed household member | Age20 or over | 2 years |
| Dependent | Age20 or over | 2 years |

## What else do people ask about Korea checkup guides by subject?

### Can foreign insured residents use national screening?

Eligible foreign insured residents use the applicable NHIS program conditions. Nationality alone does not replace current insurance and target records.

### Is the calculator an official eligibility lookup?

No. It compares published rules locally and has no access to personal NHIS records or employer lists.

### Why can a past test change the answer?

Some items are offered once in an age band, while treatment or a previous examination can affect selection or deferral.

### Can an annual worker get every cancer test annually?

The annual non-office rule applies to general screening. Cancer programs retain their own age, risk and interval conditions.

### Does a blank statistic mean zero?

No. Blank numerical snapshots are uncollected or incompatible records and are never replaced with estimated observations.
