What the O-A, O-X, LTR and DTV visas actually require, named insurers with confirmed relationships at Kasemrad International Rattanathibet and Nonthavej Hospital, and real premium ranges.
Nonthaburi has two private hospitals with genuinely long, self-published insurer lists -- Nonthavej Hospital's alone names over 65 companies, more than any other BAANLYY-covered hospital. This guide covers exactly what each long-stay visa requires, which insurers are actually confirmed to work here, what real premiums look like, and how claims and pre-existing conditions get handled. For the hospitals themselves and everyday medical costs, see our full Nonthaburi 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 Nonthaburi 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.
Nonthaburi's international-patient hospital on the Bang Yai / Central Westgate side, part of the Kasemrad Hospital Group. Its own published participating-insurer list runs to roughly 30 named companies, coordinated through a dedicated insurance liaison centre. See our full Nonthaburi healthcare guide for the hospital itself and everyday costs.
A long-established private hospital on Ngamwongwan Road with 24/7 emergency and trauma care, serving the MRT Purple Line corridor. Its own published insurance-company list is unusually long -- more than 65 named companies, including several international assistance and insurance brands alongside the expected Thai life and health insurers.
Kasemrad International Rattanathibet publishes its own list of participating insurance companies, including AIA, Thai Life Insurance, Krungthai-AXA Life, Allianz Ayudhya Life and General, Muang Thai Life and General, Dhipaya Life and General, Tokio Marine Life and General/Safety, FWD Life, Chubb Life Assurance, Prudential, Thai Ocean Life, Viriyah, Bangkok Life, Bangkok Insurance and Phillip Life among others -- coordinated through its own insurance liaison centre (ศูนย์ประกันสัมพันธ์).
Nonthavej Hospital publishes an unusually long insurance-partner list on its own site -- over 65 named companies -- that, alongside the expected Thai life and general insurers (Bangkok Life, Muang Thai, Thai Life, AIA, Allianz Ayudhya, Krungthai-AXA and similar), also includes several internationally recognisable names: Pacific Cross Health Insurance, Cigna Europe Insurance, International SOS Services (Thailand), April Assistance (Thailand), AWP Services (the Allianz Worldwide Partners assistance arm), AIG Insurance (Thailand), AXA Insurance, MSIG Insurance, LMG Insurance, Euro-Center (Thailand), Prestige International (Thailand) and Falck Global Assistance.
Both hospitals' own published lists skew heavily toward local Thai life and health insurers rather than the handful of major global expat plans (Cigna Global, Allianz Care, IMG Global) that anchor Bangkok's guide. Cigna Europe, Pacific Cross, AXA, AIG, MSIG and the Allianz-linked AWP assistance arm do appear on Nonthavej's list, which is a genuine plus -- but if you hold a major global international plan not named here, confirm current network status directly with the hospital or insurer rather than assuming it's covered.
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 Nonthaburi and elsewhere, or want direct access to Bangkok's flagship hospitals as well as local care. Confirm current Nonthaburi hospital network status directly with the insurer, since networks can change.
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 bills your insurer directly -- no upfront cash. Both Kasemrad International Rattanathibet and Nonthavej Hospital publish their own participating-insurer lists; always confirm your specific plan is on a hospital's current accepted list before you need care, not after.
Without direct billing, you pay the full bill yourself, then submit paperwork to your insurer and wait roughly two to four weeks for reimbursement. More common with smaller policies or insurers not on a hospital's direct-billing list -- budget for the 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 Nonthaburi Immigration Office or your specific embassy.
Kasemrad International Hospital Rattanathibet publishes its own list of roughly 30 participating insurers, including AIA, Thai Life, Krungthai-AXA, Allianz Ayudhya and Muang Thai. Nonthavej Hospital's own published list is even longer -- over 65 named companies -- and includes several international names such as Pacific Cross, Cigna Europe, AXA, AIG, MSIG and International SOS alongside the usual Thai insurers.
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 Nonthaburi sits inside the same metro market and 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.
Yes -- because Nonthaburi is part of Greater Bangkok, any plan that covers Bangkok's hospital networks typically extends to Kasemrad International Rattanathibet and Nonthavej Hospital as well, and residents can also reach Bumrungrad, Samitivej and the wider BDMS network in 20-40 minutes for specialist or complex care. Always confirm your specific plan's network directly rather than assuming.
Visa insurance minimums (O-A, O-X, LTR, DTV) reflect published national guidance as of this writing. Insurer lists and relationship status are drawn from Kasemrad International Rattanathibet's and Nonthavej Hospital's own published provider pages and can change -- 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.
