| Insurance Program | Fixed Validity Period? | What the Rule Actually Means |
|---|---|---|
| National Health Insurance (건강보험) | No universal fixed expiry | Generally usable while treatment for the referred condition continues |
| Medical Aid (의료급여) | 7 days, excluding public holidays | Must be submitted within 7 days; this is a submission deadline, not a treatment cutoff |
Whether a Korean referral letter expires depends entirely on which insurance program issued it, and mixing up the two is a common source of confusion, including among Korean patients themselves.
Does a Standard Health Insurance Referral Letter Expire?
For patients under standard National Health Insurance (건강보험), there is no universal fixed expiry date on a referral letter (진료의뢰서, also called 요양급여의뢰서). Multiple hospitals’ own official policies state directly that there is no separate validity period for this document, including Seoul National University Hospital, Kyungpook National University Hospital, and Ewha Womans University Mokdong Hospital.
The Health Insurance Review and Assessment Service takes a similar position: a new referral generally should not be required while treatment for the referred condition is still ongoing. In practice, this means validity is tied to the continuation of treatment for that specific condition, not a fixed number of calendar days. Hospitals still recommend bringing a reasonably recent referral that reflects your current condition, since an old one may not accurately describe your situation anymore.
Why Do People Think There Is a 7-Day Rule?
The 7-day rule is real, but it applies specifically to Medical Aid (의료급여), a separate public assistance program for eligible low-income patients, not to standard National Health Insurance. Under Medical Aid regulations, the referral must be submitted to the receiving institution within 7 days of issuance, excluding public holidays.
Hospital policy on this varies enough in practice that a quick question in EEIK’s Facebook Groups directory often gets a faster, clearer answer than the paperwork itself does. Even within Medical Aid, this is a submission deadline, not a treatment cutoff. Once properly submitted within that window, the referral can continue to support treatment of the referred condition until that treatment is considered complete. Some hospital FAQ pages still repeat the 7-day figure without clarifying it only applies to Medical Aid, which is likely where the confusion spreads from.
Is a Referral Only Valid for One Department?
Generally yes. A referral letter is tied to the specific medical department noted on it, based on the clinical opinion it contains. If you need to see a different department, hospitals typically require a new referral describing that department, unless the receiving hospital arranges an internal cross-department consultation on your behalf.
Frequently Asked Questions
Q: Does a standard health insurance referral letter in Korea expire after a certain number of days?
No fixed expiry is confirmed for standard National Health Insurance referrals. Validity is generally linked to ongoing treatment of the referred condition rather than a set number of days, though bringing a reasonably current referral is still recommended.
Q: Does the 7-day referral rule apply to everyone in Korea?
No. The 7-day submission deadline applies specifically to Medical Aid (의료급여) recipients, a separate program from standard National Health Insurance. Standard insurance referrals do not carry this same fixed deadline.
Q: Can I use the same referral letter to see a different department at the hospital?
Generally no. A referral is tied to the specific department described in it. Seeing a different department typically requires a new referral for that department, unless the hospital arranges an internal consultation between departments.
Referral rules and hospital policies can vary and do get updated. Verify current requirements directly with the receiving hospital or the Health Insurance Review and Assessment Service before relying on any timeline here.
