💡 Two Refund Modes

Pre-payment (rare)A single Korean hospital exceeding the cap bills the excess directly to the Korean NHIS instead of the patient (long stays, etc.)
Post-payment (standard)Around August the Korean NHIS tallies prior-year Korean co-pays and refunds the excess to the member's Korean account — recipients receive a notice

This South Korea–only summary follows Korea's National Health Insurance Act and Korean NHIS guidance (as of April 2026). Korean tier caps and nursing-special caps are re-announced each August. Actual Korean eligibility and amount depend on NHIS settlement; non-covered services, Korean private indemnity insurance, and Korean medical-aid programs vary by case. This is a non-binding estimate — confirm with Korean NHIS Minwon Yeogiyo, hotline 1577-1000, or your Korean NHIS branch before relying on any figure.

What is Korea's Out-of-Pocket Cap Refund?

South Korea's Out-of-Pocket Cap (본인부담상한제) under the Korean National Health Insurance Act §44-2 limits the annual Korean co-payment burden of Korean NHI members. Annual Korean NHI-covered co-payments (excluding non-covered services) above the income-tier cap are refunded by the Korean NHIS after a post-year settlement. 2025 Korean caps ranged from 870,000 KRW (Tier 1) to 8,080,000 KRW (Tier 10), with higher special caps for low-income tiers (1–5) whose Korean nursing-hospital stays exceed 120 days. The Korean NHIS mails a notice around August each year; recipients then apply on Korean Minwon Yeogiyo (minwon.nhis.or.kr), The건강보험 app, an NHIS branch, or by phoning 1577-1000. Unclaimed Korean refunds expire after 5 years. Korean medical-aid recipients follow a separate 'Medical Aid Co-payment Compensation' program.

Is the Korean refund automatic or must I apply?

Korean NHIS sends a notice, but you must file to receive it. Once a Korean account is registered it may auto-pay in later years. Unclaimed Korean refunds expire after 5 years.

Do Korean non-covered fees count?

No. Korean non-covered fees (선택진료, premium room, cosmetic surgery, some MRI, robotic surgery) are excluded. If non-covered costs are high, see Korea's Catastrophic Medical Expense Support program.

How do I find my Korean income tier?

Log in to Korean Minwon Yeogiyo (minwon.nhis.or.kr) → Premium → Tier Inquiry. Korean tiers are calculated from the prior April–March NHI premium and may change yearly.

Does it overlap with Korean private indemnity insurance?

Korean out-of-pocket cap refunds are excluded from Korean private indemnity (실손) coverage — if the Korean private insurer paid first, you may need to return that portion.

How does the Korean nursing-hospital special cap work?

For Korean nursing-hospital stays exceeding 120 days, low-income tiers (1–5) receive higher separate caps to prevent moral hazard; high-income tiers (8–10) use the standard cap.

Are Korean family members aggregated?

No. Korean co-pays are calculated per individual, not per household — Korean dependents have their own caps.
