When is each round?
The NHIS sets the target group for each checkup period. The table below covers rounds 1 through 4.
| Round | General checkup timing | Dental checkup |
|---|---|---|
| Round 1 | 14 to 35 days after birth | None |
| Round 2 | 4 to 6 months after birth | None |
| Round 3 | 9 to 12 months after birth | None |
| Round 4 | 18 to 24 months after birth | 18 to 29 months after birth |
The next table covers rounds 5 through 8.
| Round | General checkup timing | Dental checkup |
|---|---|---|
| Round 5 | 30 to 36 months after birth | 30 to 41 months after birth |
| Round 6 | 42 to 48 months after birth | 42 to 53 months after birth |
| Round 7 | 54 to 60 months after birth | 54 to 65 months after birth |
| Round 8 | 66 to 71 months after birth | None |
The dental checkup window is wider than the general checkup window. Because the two windows differ, confirm with the clinic which checkup you are getting.
Who pays?
The NHIS guide says there is no out-of-pocket cost. For National Health Insurance subscribers, the NHIS pays the full amount, and for Medical Aid recipients, the national and local governments pay. Policy Briefing describes the same thing (2025-04-21).
The cost of follow-up treatment or detailed tests after a checkup is not stated in the materials I checked. Ask the clinic about costs when you receive their guidance.
What does the checkup look at?
The checkup items listed in the NHIS guide are as follows.
- Questionnaire and examination: questionnaire, physical exam, hearing and vision questions, vision test, whisper test, vaccination check
- Body measurements: height, weight (body mass index), head circumference
- Health education: preventing accidents, nutrition, preventing sudden infant death syndrome, oral health, toilet training, and more
- Developmental assessment: assessment and counseling with the Korean Developmental Screening Test for Infants and Children (K-DST)
- Dental checkup: oral questionnaire and examination, plus oral health education for the guardian and child
The details of which items are checked in which round are not in these materials. Get that information at the checkup clinic.
How do you keep track of the schedule?
Work out the window by months since birth, not by birthday. For example, 9 to 12 months after birth is the round 3 window.
- Calculate how many months old your child is now from the date of birth.
- Find the matching round and dental checkup window in the table above.
- Check which clinics offer the checkup and when in the National Health Insurance Service guide.
What if something worries you?
If you are worried about growth or development between checkups, do not wait for the checkup date. Talk to a pediatrician. This article only explains checkup timing and does not replace diagnosis or treatment.
