Koh Samui is a well-equipped island for private healthcare, with a handful of internationally-experienced hospitals clustered around Bophut and Chaweng doing the heavy lifting for foreigners. Here’s the plain-English directory: who’s who, what each is known for, where they sit, how insurance and cashless billing work, what care costs, how medevac and referral to Bangkok work for complex cases, and how to choose a home near the right one. Unbiased, never paid placement.
Koh Samui’s main international-standard private hospitals — Bangkok Hospital Samui, Bandon International, Thai International and Samui International — are good, English-speaking and used to foreigners, clustered mostly in Bophut and Chaweng. Pick a primary hospital early based on proximity, your insurer’s cashless network and whether your policy covers medevac/air-ambulance transfer to Bangkok for complex cases, save 1669 for emergencies, and know how far it is before you choose where to live.
On an island, the choice of home and the choice of hospital are linked more tightly than in a mainland city. Koh Samui’s main private hospitals sit mostly on the northeast side, around Bophut and Chaweng, and getting off the island for specialist care means a drive to the airport and a flight rather than a short taxi ride to another hospital. That’s a real factor to weigh, not an afterthought. Read this as a directory first, then use our area tools to put it on the map before you sign a lease.
A few names come up again and again among Koh Samui’s foreign residents. Each is used to treating international patients, with English-speaking staff:
The government-run Samui Hospital in Nathon is the island’s public facility — reasonably equipped but generally used by residents rather than foreign long-stayers, unless it’s genuinely the closest option in an emergency. This isn’t an exhaustive list of every clinic on the island, but these cover most of what foreign residents need.
All handle general and emergency care, but a few reputations are worth knowing when you pick a primary hospital:

What makes these hospitals workable for foreigners is the international-patient infrastructure built around them:

By Western standards, outpatient and routine care at Koh Samui’s private hospitals is generally affordable — a consultation, tests and medication in one visit without the bill shock many foreigners expect. Costs climb quickly for inpatient stays, surgery and especially for any air-ambulance or inter-hospital transfer, which is exactly why insurance matters more than self-paying on an island. We deliberately don’t publish specific prices: they vary between hospitals and change over time. Ask the international department for a written quote, confirm what your insurer covers (including evacuation), bring an international card where accepted, and keep itemised receipts for any claim.
In a serious emergency many residents also call their chosen private hospital directly, because the larger Koh Samui hospitals operate their own ambulance services and can dispatch a team that already knows your records. On an island, response time and distance both matter more than on the mainland, so save your primary hospital’s main and ambulance numbers and keep your insurance card on your phone. Confirm all emergency numbers locally when you arrive, as services and numbers can change.
