Koh Chang's healthcare sits between a big island's needs and a resort island's infrastructure: a 24/7 private hospital run by the Bangkok Hospital Group, a cheaper government hospital, village clinics and one dentist. Here's the relocation view — where to go, what it costs, and how insurance and mainland transfers work. Figures are 2026 guide ranges (≈ THB 35–36 = USD 1).
Koh Chang has no airport of its own and no full tertiary hospital, but it does have a genuine 24-hour private hospital — Koh Chang International Hospital, run by the Bangkok Hospital Group at the southern end of White Sand Beach — plus a public government hospital at Dan Mai on the east coast and a scatter of village clinics along the west-coast beach road. For everyday illness and injury, the island covers itself reasonably well. Anything more serious escalates in stages: first to Bangkok Hospital Trat on the mainland (a ferry and short drive away), then, if needed, on to Bangkok's leading private hospitals. For live rent by area, use the BAANLYY Koh Chang hub.
Routine and emergency care stays on-island; anything beyond it escalates off-island in stages, first to Trat and then, if needed, to Bangkok.
| Facility | Type | Area | Known for |
|---|---|---|---|
| Koh Chang International Hospital | Private · Bangkok Hospital Group (BDMS) | White Sand Beach (southern end, 14/16 Moo 4) | Started as Koh Chang International Clinic in 2005 and was upgraded to full hospital status in 2015. Open 24/7 with emergency care, inpatient rooms, lab, X-ray and CT scan, and an emergency transfer system — including ambulance and medical boat services — to Bangkok Hospital Trat on the mainland. |
| Koh Chang Hospital (government) | Public · general | Dan Mai, east coast, ~15 min drive south of the ferry piers | The island's public hospital, treating both Thai nationals and tourists at Thailand public-hospital rates. Some English spoken; expect longer waits and more basic facilities than the private hospital, but genuinely cheaper for routine care. |
| Village health clinics | Nurse-staffed local clinics | Klong Son, Klong Prao, Bang Bao, Salak Phet | Small clinics for everyday problems — colds, minor infections, scooter-spill cuts and scrapes, wound cleaning and dressing. Budget-friendly and useful for anything that doesn't need a full consultation; bring your passport as ID. |
| Pharmacies | Retail pharmacy | All main west-coast beach areas | Well stocked and found on every main beach strip; pharmacists commonly speak good English and can advise on and dispense treatment for straightforward ailments without a clinic visit. |
| Koh Chang Dental Clinic | Private dental | Klong Prao (opposite The Splash resort) | The island's main dental practice — routine and emergency dental work; book ahead in high season, as it's popular with both residents and visiting patients. |
| Bangkok Hospital Trat (mainland transfer) | Private · international | Trat town, mainland, via ferry + road | The standard escalation point for anything beyond what the Koh Chang branch can handle — Koh Chang International Hospital is run under Bangkok Hospital Trat and refers upward to it directly, with onward referral to Bangkok's leading hospitals for complex or specialist cases. |
The gap between the private hospital and the government hospital is large — the private branch is fast and English-speaking but priced at international rates, while the government hospital is a fraction of the cost. Guide ranges in THB:
| Service | Typical cost |
|---|---|
| Koh Chang International Hospital — doctor consultation | Historically quoted around THB 4,000 (confirm current pricing directly) |
| Same hospital group's Trat mainland hospital — doctor consultation | Historically quoted around THB 400 for comparison |
| Koh Chang Hospital (government, Dan Mai) — outpatient visit | Typical Thailand public-hospital rate, roughly THB 200–800 |
| Village clinic — minor wound care / dressing | Low cost; confirm at the clinic, cash-friendly |
| Rabies vaccination course (after a stray-dog bite) | Roughly THB 1,200–1,500 per dose, several doses required |
Costs vary by facility, case and how long ago pricing was last confirmed; always ask for a current quote directly, and check exactly what your insurance covers before you need it, not after.
Insurance rules differ by visa, and requirements change — confirm the current rule for your visa before you apply or extend. On an island with one private hospital branch, comprehensive cover is worth having regardless of what your visa strictly requires. As a planning guide:
The O-A in particular has historically required health insurance meeting set minimum cover; budget for a comprehensive expat policy and keep proof current at extension time.
Requires health insurance or a proof-of-funds/self-insurance threshold as part of qualifying — a policy meeting the stated minimum, or the equivalent deposit.
No mandatory insurance line in the core requirements, but travel/health cover is strongly advised — on an island whose main private hospital is a single branch, a serious case can mean a costly transfer to Trat or Bangkok.
International private medical insurance (IPMI) or a solid travel-medical policy that explicitly includes medical evacuation, given the practical distance to full specialist care.
Confirm your policy covers both the private Koh Chang International Hospital directly (for fast, English-language care) and any mainland transfer, since paediatric specialists are on the mainland, not the island.
For anything urgent, going directly to Koh Chang International Hospital (24/7, White Sand Beach) is usually the fastest option on the island. For cases beyond its scope, the hospital runs its own transfer system — ambulance and medical boat services — to Bangkok Hospital Trat, and onward to Bangkok when specialist care is needed. Keep these numbers saved:
| Service | Number |
|---|---|
| National emergency medical / ambulance | 1669 |
| Police | 191 |
| Tourist Police (English) | 1155 |
| Fire | 199 |
| Koh Chang International Hospital (Bangkok Hospital, 24/7) | +66 39 551 554 |
Pharmacies. Well stocked and present on every main beach strip, with pharmacists who commonly speak good English and can advise on straightforward ailments without a clinic visit. Dental. Koh Chang Dental Clinic in Klong Prao (opposite The Splash resort) is the island's main practice for routine and emergency work — book ahead in high season, as more complex dental work is often easier to schedule on a trip to Trat or Bangkok where choice is wider.
Yes, for an island of its size — Koh Chang International Hospital, run by the Bangkok Hospital Group at the southern end of White Sand Beach, is open 24/7 with emergency care, inpatient rooms, lab, X-ray and CT scan. What Koh Chang doesn't have is a full tertiary/specialist hospital: anything complex is referred to Bangkok Hospital Trat on the mainland, and from there on to Bangkok if needed.
Koh Chang International Hospital (private, White Sand Beach) is fast, English-speaking and open 24/7, but priced at private international rates. Koh Chang Hospital (government, Dan Mai on the east coast) is much cheaper and treats both Thai nationals and tourists, with some English spoken, more basic facilities and longer waits.
Call 1669 for the national ambulance service, or go directly to Koh Chang International Hospital, which operates 24/7 and has its own emergency transfer system — including ambulance and medical boat services — to move patients to Bangkok Hospital Trat on the mainland, and onward to Bangkok for specialist or complex cases.
It depends on your visa. The retirement O-A and the LTR visa carry specific insurance or proof-of-funds requirements; the DTV does not mandate it but strongly rewards having it, since the island's private hospital is a single branch and any serious case likely means a paid transfer to Trat or Bangkok.
Yes — Koh Chang Dental Clinic in Klong Prao, opposite The Splash resort, is the island's main dental practice for both routine and emergency work. Book ahead in high season.
A consultation at the private Koh Chang International Hospital has historically been quoted around THB 4,000 — noticeably more than the roughly THB 400 the same hospital group charges at its Trat mainland branch for the same visit. The government hospital at Dan Mai is cheaper still, at typical Thailand public-hospital rates of roughly THB 200–800. Always confirm current pricing directly, as costs change.
