Korean Medical Tourism 2026: KHIDI Numbers Worth Knowing

Every couple of months I pull the latest KHIDI medical tourism release, sit down with a coffee, and read it the way I used to read economic data when I was still working in policy. The 2026 numbers, covering the most recently reported full year of foreign patient activity, are genuinely worth a look. The headline figure is record-setting on its own, but the more interesting story is in the breakdowns: who exactly is coming, from where, for what, and where they cluster within Seoul. As an American patient who has been flying to Gangnam for treatments for the past few years, I read these numbers as both a journalist and a data point inside them. Here is what the latest release actually says, and what I think is worth knowing if you are weighing a Korea trip yourself.

What the 2026 KHIDI release actually shows, top-line

The Korea Health Industry Development Institute (KHIDI) is the government-affiliated agency that compiles annual foreign patient statistics under the Medical Service Act, and its most recent release covers calendar year 2024 — the standard one-year reporting lag — with preliminary 2025 figures published in interim quarterly updates. The 2024 full-year report logged just over 1.17 million foreign patients treated across registered Korean medical institutions, which was a record and represented roughly a 92 percent year-over-year increase over 2023's 605,000. Preliminary 2025 quarterly data suggests the trajectory continued upward, with KHIDI projecting full-year 2025 to land somewhere between 1.4 and 1.6 million when the official release lands in mid-2026.

Those numbers matter because they include both inpatient and outpatient visits, which is how KHIDI counts. A patient who comes in for three Ultherapy sessions across one trip counts as three outpatient visits, not one patient. That is worth understanding before you compare these figures to other countries' tourism statistics, which sometimes count only unique visitors. The actual number of distinct foreign individuals who received treatment in Korea in 2024 was closer to 600,000 to 700,000 in KHIDI's own estimation, with the average patient generating about 1.7 to 1.9 visits per trip. Either way, the trend line is unambiguous. Korean medical tourism is growing fast, and 2024 was the inflection year that made it impossible to ignore.

The US visitor breakdown — what KHIDI says about Americans

American patients have historically been a smaller share of KHIDI's foreign patient totals than their cultural visibility would suggest, but that gap has been closing fast. In the 2024 full-year report, US patients accounted for roughly 7 to 8 percent of total foreign patient visits, which works out to around 90,000 to 95,000 visit-counts. That puts the US firmly in the top five source countries, behind China, Japan, the United States in third or fourth depending on the quarter, and Thailand and Vietnam rotating in the next tier. The year-over-year US growth was reported by KHIDI at roughly 60 to 70 percent, which outpaces the overall foreign patient growth rate.

The state-of-origin breakdown is harder to pull from public KHIDI data, since most state-level granularity comes from secondary sources like the Korea Tourism Organization and individual clinic reporting rather than KHIDI's national rollup. What the secondary data suggests, with appropriate caveats: California, New York, Texas, Washington, and Hawaii are the top five US states by Korean medical tourism volume, with California alone accounting for roughly 25 to 30 percent of US patient flow. The age cohort skew is also notable. KHIDI's foreign patient data shows that for US patients specifically, the 30-49 age range represents about 55 to 60 percent of the total, with 50-69 making up another 25 to 30 percent. The under-30 cohort is smaller than headline coverage might suggest. Top procedures for US patients in the 2024 dataset, in order: dermatology and aesthetic procedures (Ultherapy, RF tightening, laser, injectables) at roughly 35 to 40 percent of US visits, followed by health checkups, ophthalmology, plastic surgery, and orthopedics.

The Chinese, Japanese, and Southeast Asian visitor mix

The non-American foreign patient mix has shifted noticeably in the past three reporting years, and the 2024 KHIDI release captures that shift. Chinese patients returned to the top of the source country rankings in 2024 after a multi-year pandemic-era dip, accounting for roughly 28 to 32 percent of total foreign patient visits. The Chinese rebound was the single biggest driver of the 92 percent overall growth rate, and KHIDI noted that the 2024 Chinese visit volume actually exceeded 2019's pre-pandemic peak. Most of that volume concentrated on dermatology, aesthetic procedures, and health checkups, with the Gangnam district as the clear geographic anchor.

Japanese patients held roughly 18 to 22 percent of total visits in 2024, with growth driven heavily by short-stay visa-free travelers running 2-3 day weekend trips for procedures and health screenings. The Japanese cohort skews younger and more procedure-focused than the Chinese cohort. Southeast Asian visitors — Thailand, Vietnam, Indonesia, the Philippines, Singapore — collectively made up around 15 to 18 percent, with Thailand and Vietnam leading and growth rates that outpaced even the US. Within the SE Asian mix, KHIDI noted a strong tilt toward dermatology and dental procedures, with Vietnamese patients particularly concentrated in dental work. The Middle Eastern share, primarily UAE and Saudi Arabia, hovered around 4 to 5 percent and skewed toward orthopedics and complex inpatient procedures rather than aesthetic work.

Gangnam vs Apgujeong vs Cheongdam — district-level density

Gangnam-gu, the broader administrative district that contains Apgujeong, Cheongdam, and the Gangnam Station core, is the dominant geographic concentration for foreign aesthetic patients in Korea, accounting for roughly 60 to 65 percent of all foreign aesthetic procedure volume in KHIDI's clinic-level reporting for 2024. Within Gangnam-gu itself, the density distribution gets more interesting. The Gangnam Station core area, including Sinsa-dong south of the river, runs at moderate foreign-patient density, with most clinics in this area splitting their patient base roughly 60 to 70 percent domestic and 30 to 40 percent foreign. The Apgujeong-Rodeo and Cheongdam corridors, by contrast, have foreign-patient ratios that can exceed 50 percent at certain larger clinics, with Cheongdam specifically running the highest concentration of premium-tier clinics and the highest average foreign-patient revenue per visit.

Myeongdong, in the Jung-gu district closer to central Seoul, is the second cluster, particularly strong for Chinese and Japanese patients given its central tourist accessibility. Myeongdong runs roughly 18 to 22 percent of total foreign aesthetic procedure volume by KHIDI district-level breakdowns. Insadong and Jongno round out the smaller central clusters, with the rest distributed across Songpa, Mapo, and increasingly Bundang and Pangyo for medical-tech-adjacent care. The Incheon Airport medical wing, while small in raw volume, has been growing fast for transit-oriented medical procedures and now accounts for a meaningful share of same-day or short-stay foreign patient activity. Patients report that the Gangnam concentration is genuinely felt on the ground — walking through Apgujeong-Rodeo on a Friday afternoon, you can hear Mandarin, English, Japanese, and Thai in roughly equal measure, and most of the larger clinic lobbies have multilingual coordinators standard.

The revenue side — what foreign patients actually spend

KHIDI publishes both visit count and total revenue figures, and the revenue side of the 2024 release is where the longer-term economic story shows up. Total foreign patient revenue for 2024 reached approximately 1.4 trillion won, or roughly 1.05 to 1.1 billion USD at average 2024 exchange rates. That was up about 73 percent year-over-year. Per-patient revenue, however, was actually down slightly compared to 2023 because the visit-volume growth was faster than the revenue growth. The KHIDI commentary attributed this to a shift in patient mix toward shorter, lower-cost procedures (dermatology, injectables, health screenings) versus longer, higher-cost procedures (complex plastic surgery, orthopedic work, oncology).

Dermatology and aesthetic procedures specifically generated about 35 to 40 percent of total foreign patient revenue, which is roughly proportional to their share of visit volume. Plastic surgery, despite being a smaller share of total visits, generated outsized revenue per visit and accounted for about 18 to 22 percent of total foreign patient revenue. Health checkups generated about 8 to 10 percent of revenue. The remaining mix included internal medicine, ophthalmology, dentistry, and a long tail of specialized care. The five-year trend in foreign patient revenue, from 2020 through 2024, shows a strong recovery curve from the 2020-2021 pandemic floor, with the 2024 number now meaningfully above the 2019 pre-pandemic peak. The Korean Ministry of Health and Welfare has stated public targets for continued growth, with KHIDI projections suggesting foreign patient revenue could reach 2 trillion won by 2027 if the current trajectory holds.

Frequently asked questions

How many foreign patients did Korea treat in 2024 according to KHIDI?

Just over 1.17 million foreign patient visits in calendar year 2024, which was a record and represented roughly 92 percent year-over-year growth over 2023. The actual number of distinct foreign individuals was closer to 600,000 to 700,000 because the visit count includes repeat visits within a trip. Preliminary 2025 quarterly data suggests the upward trend continued, with KHIDI projecting full-year 2025 between 1.4 and 1.6 million when the official release lands in mid-2026.

What share of Korean medical tourism is American?

US patients accounted for roughly 7 to 8 percent of total foreign patient visits in the 2024 KHIDI release, or around 90,000 to 95,000 visit counts. Year-over-year US growth was reported at 60 to 70 percent, faster than the overall foreign patient growth rate. The US is firmly in the top five source countries, with the top three being China, Japan, and the United States rotating in third or fourth depending on the quarter. California alone accounts for roughly 25 to 30 percent of US patient flow according to secondary tracking.

Where in Seoul do foreign aesthetic patients actually concentrate?

Gangnam-gu accounts for roughly 60 to 65 percent of all foreign aesthetic procedure volume in KHIDI clinic-level reporting. Within Gangnam, the Apgujeong-Rodeo and Cheongdam corridors run the highest foreign-patient density, with some larger clinics exceeding 50 percent foreign-patient share. Myeongdong is the second cluster at 18 to 22 percent, particularly strong for Chinese and Japanese patients given its central tourist accessibility.

What procedures do US patients in Korea actually get?

Dermatology and aesthetic procedures led the US patient breakdown in the 2024 KHIDI dataset at roughly 35 to 40 percent of US visits, including Ultherapy, RF tightening, lasers, and injectables. Health checkups, ophthalmology, plastic surgery, and orthopedics rounded out the next tiers. The age cohort skew for US patients shows about 55 to 60 percent in the 30-49 age range, with another 25 to 30 percent in the 50-69 range. The under-30 cohort is smaller than headline coverage might suggest.

Is Korean medical tourism revenue actually growing or just visit count?

Both, but at different rates. Total foreign patient revenue reached approximately 1.4 trillion won in 2024 (roughly 1.05 to 1.1 billion USD), up about 73 percent year-over-year. Visit count grew faster at 92 percent because the patient mix shifted toward shorter, lower-cost procedures like dermatology and injectables. Per-patient revenue was actually down slightly. KHIDI projections suggest foreign patient revenue could reach 2 trillion won by 2027 if the current trajectory holds.

How do I verify these numbers myself?

KHIDI publishes its annual foreign patient statistics report at khidi.or.kr in both Korean and English, with a one-year reporting lag (so the 2024 full-year report is the most recent comprehensive release as of mid-2026). The Korea Tourism Organization and the Ministry of Health and Welfare publish supplementary breakdowns. Quarterly preliminary releases come out about two months after each quarter ends. For US patient state-level breakdowns, secondary sources like industry associations and individual clinic reporting fill in granularity that KHIDI's national rollup does not provide directly.
