What the O-A, O-X, LTR and DTV visas actually require, which mainland hospitals coordinate with international insurers, and real premium ranges.
Mainland Surat Thani has two private hospitals with real insurance-coordination departments -- Bangkok Hospital Surat (part of the BDMS network) and Thaksin Hospital -- plus the public Surat Thani Hospital for pay-and-claim care. Neither private hospital publishes a definitive named-insurer list specific to its Surat branch online, so this guide is honest about what's confirmed and what needs a phone call. It covers exactly what each long-stay visa requires, what real premiums look like, and how claims and pre-existing conditions get handled. If you're island-hopping from the Surat Thani ferry piers, Koh Samui has the area's best-equipped private hospitals as a fallback for anything serious. For the hospitals themselves and everyday medical costs, see our full Surat Thani healthcare guide.
The standard minimum is THB 400,000 inpatient (IPD) and THB 40,000 outpatient (OPD) cover per policy year, from a Thai insurer on the official TGIA-approved list or an international insurer holding a Foreign Insurance Certificate. Some Thai embassies handling the initial application abroad instead require USD 100,000 per policy year -- confirm which figure your specific embassy or the Surat Thani Immigration Office is asking for before buying a policy.
O-X carries the same THB 400,000 IPD / THB 40,000 OPD minimum as O-A for renewals at Thai immigration offices, but initial applications through a Thai embassy abroad commonly ask for the higher USD 100,000 figure instead. Every applicant on the visa, including a spouse or children, must maintain continuous cover for the full stay.
The Board of Investment's LTR visa requires inpatient coverage of at least USD 50,000 per year, with at least 10 months remaining on the policy at application. The BOI also accepts a USD 100,000 bank deposit, a THB 3 million Thai bank deposit, or proof of Thai Social Security coverage instead of a policy.
There is no single Thailand-wide government mandate for DTV insurance. Individual Thai embassies and consulates retain discretion over their own checklists, and several do ask for proof of cover -- commonly the same THB 400,000/40,000 figures used for O-A, or a USD 50,000 minimum. Confirm directly with the specific embassy or consulate you're applying through.
Bangkok Hospital Surat is a confirmed member of BDMS (Bangkok Dusit Medical Services), Thailand's largest private hospital network, and runs its own Insurance Service Coordination Department handling inpatient eligibility checks, cost estimates, and claims coordination with insurers. Unlike some BDMS flagship campuses in Bangkok and Pattaya, Bangkok Hospital Surat does not publish its own named-insurer list online -- call its Insurance Service Coordination Department directly to confirm your specific policy is covered before admission.
A long-established private hospital (opened 1983) at 309/2 Talat Mai Road, Muang district, widely used by long-term residents for routine and emergency care and reportedly better equipped than the Koh Samui hospitals combined. No public named international-insurer list was found on the hospital's own site -- confirm direct-billing status for your specific insurer with the hospital before you need care.
The provincial public hospital, with 24-hour emergency care. Public hospitals in Thailand almost never hold direct-billing relationships with international insurers, so expect to pay upfront here and file for reimbursement afterward.
Bangkok Hospital Group's own published insurer pages (its Bangkok and Pattaya campuses) list well over a hundred international insurers and assistance companies it has established direct-billing relationships with, including Bupa Global, Cigna Global, Allianz Partners, AXA, IMG, MSH International, William Russell, Global Benefits Group and Tokio Marine & Nichido. This reflects group-wide infrastructure Bangkok Hospital Surat shares as a BDMS member, but it is not the same as a Surat-branch-specific confirmed list -- verify your insurer's current status with the Surat Insurance Service Coordination Department directly.
A Thailand-focused insurer commonly cited as the cheapest tier for comparable cover, though with a smaller worldwide footprint outside Thailand than global international plans. Confirm current Surat Thani hospital network status directly with the insurer, since networks can change.
These insurers add worldwide cover, higher annual and lifetime limits, and in some cases moratorium underwriting for pre-existing conditions -- useful if you split time between Surat Thani and elsewhere, including trips out to Koh Samui, Koh Phangan or Koh Tao.
If a visa requires a policy from the official Thai General Insurance Association (TGIA) list specifically -- as O-A and O-X do -- confirm the insurer you're considering is actually on that list before buying.
Basic inpatient-only plans run roughly THB 20,000-40,000 a year. Inpatient plus basic outpatient cover moves to roughly THB 40,000-80,000. Comprehensive plans with higher limits run THB 80,000-200,000, and premium worldwide plans can exceed THB 200,000 a year -- broadly consistent nationwide regardless of which city you're based in.
Roughly USD 70-250 a month in your 30s, USD 100-300 a month in your 40s, and USD 150-400 a month in your 50s -- indicative ranges, not fixed quotes; actual pricing depends on health history, deductible and exact plan.
Roughly USD 150-360 a month in your 30s and USD 200-480 a month in your 40s for a global tier plan -- meaningfully higher than Thailand-focused options, reflecting the worldwide network and higher limits.
With direct billing, you show your insurance card at admission and the hospital's insurance department contacts your insurer for a guarantee of payment. Bangkok Hospital Surat and Thaksin Hospital both run dedicated insurance-coordination teams, but neither publishes a definitive named-insurer list online for the Surat branch -- call ahead and confirm your specific plan before you need care, not after.
At Surat Thani Hospital (public) and for any insurer without a confirmed direct-billing arrangement, you pay the full bill yourself, then submit paperwork to your insurer and wait roughly two to four weeks for reimbursement. Budget for that cash-flow gap if your plan works this way.
Insurers generally treat anything diagnosed or treated in the 2-5 years before your policy starts as pre-existing. Full, honest disclosure matters: insurers can and do deny future claims entirely if a condition was undisclosed.
Most standard plans exclude pre-existing conditions permanently. Some plans instead impose a 12-24 month waiting period before covering a disclosed condition. A smaller group of premium international insurers -- Allianz Care is a commonly cited example -- offer moratorium or full-underwriting options that can bring a pre-existing condition into cover after a claims-free window, typically at a higher premium.
THB 400,000 inpatient and THB 40,000 outpatient cover per policy year, from an insurer on Thailand's official TGIA list or an international insurer with a Foreign Insurance Certificate -- though some embassies handling the initial application ask for USD 100,000 instead. Confirm which figure applies with the Surat Thani Immigration Office or your specific embassy.
Bangkok Hospital Surat (a confirmed BDMS network member) and Thaksin Hospital both run dedicated insurance-coordination departments and can request a guarantee of payment from your insurer. Neither publishes a public named-insurer list specific to the Surat branch, so call ahead to confirm your specific plan before you need care. The public Surat Thani Hospital generally does not offer direct billing.
It's genuinely unsettled. There's no single Thailand-wide government mandate, but individual Thai embassies and consulates set their own documentation requirements and several do ask for proof of cover -- commonly THB 400,000/40,000 or USD 50,000. Check directly with the specific embassy or consulate you're applying through.
Roughly THB 20,000-40,000 a year for basic inpatient-only cover, THB 40,000-80,000 for inpatient plus basic outpatient, and THB 80,000-200,000+ for comprehensive plans -- broadly the same national pricing as Bangkok, since premiums aren't typically city-specific in Thailand.
Usually not straightforwardly. Most plans permanently exclude conditions diagnosed or treated in the 2-5 years before your policy starts, though some impose a 12-24 month waiting period instead. A handful of premium international insurers offer moratorium underwriting that can bring a condition into cover later, typically at a higher premium. Always disclose fully.
Visa insurance minimums (O-A, O-X, LTR, DTV) reflect published national guidance as of this writing. Bangkok Hospital Surat's insurance-department services and Bangkok Hospital Group's broader named-insurer directory are drawn from the hospital group's own published pages; Bangkok Hospital Surat does not publish a branch-specific named-insurer list. Always confirm current requirements and network status directly with your Thai embassy, the Immigration Bureau, the hospital or the insurer before buying a policy or relying on a figure for a visa application.
