The Destination Thailand Visa has put thousands of remote workers, freelancers, and long-stay foreigners (people who stay for many months at a time, often 180+ days a year) into a position the insurance market was not really designed for. They live in Thailand in every practical sense, but on a visa that, on paper, looks like a series of long visits. Many of them remain on the travel insurance they arrived with, because it is cheap, easy to buy online, and has not obviously caused any problems yet.
To explain why that often becomes a problem later, we sat down with Thuyvan Zhang at LUMA, who works on health insurance for foreigners across Thailand and Southeast Asia. The list below is drawn from her experience with long-stay clients, and from the situations she sees most often when someone tries to claim on a travel policy after living in Thailand for longer than the product was built for.
Travel insurance is the right product for a trip. It is generally not the right product as your main cover once you live somewhere.
Here are ten specific reasons why:
1. Travel insurance is bought policy by policy, not renewed
Travel insurance is purchased one trip at a time. When you buy a new policy, it starts fresh. There is no continuity from one policy to the next. People talk about “renewing” their travel insurance, but what is actually happening is that they are purchasing a new policy each time. Health insurance, by contrast, is designed to be held year after year, with the same policy carrying forward.
2. Pre-existing conditions carry forward between travel policies
Anything claimed under one travel policy becomes a pre-existing exclusion on the next. The insurer does not need to ask medical questions when you buy online, because the pre-existing exclusion does the work automatically. Your first policy covers you with a clean record. Your second policy looks identical when you buy it, but quietly excludes anything that came up under the first one. Most people only discover this when they make a claim.
3. There is a maximum trip length on every travel policy
Most travel insurance policies cap a single trip at 30, 60, 90, or 180 days. After that, the cover ends. Annual or multi-trip policies do not mean year-round cover either. The word “annual” describes when the policy expires, not how long each trip can be. Each trip within an annual policy is usually capped at 30, 35, or 90 days. A DTV holder spending 180 days in Thailand often finds their travel policy expires before the visa entry does.
4. Travel insurance is emergency-only by design
Travel insurance is built to respond to unexpected events: accidents, sudden illness, and evacuation home. The routine medical care that fills most of a normal year is not what the product is for. For someone living in Thailand long-term, that gap matters because the average year contains far more routine appointments than emergencies.
5. Primary and preventive care are out of scope
Annual check-ups, routine bloodwork, dermatology consults, screenings, follow-up appointments, prescription refills: travel insurance generally does not cover any of this. For long-term residents, this is the everyday use of healthcare, and travel insurance is not built to support it.
6. Maternity care is not included
Pregnancy care, antenatal appointments, delivery, and postnatal care: standard travel insurance excludes maternity entirely. For someone living in Thailand who is planning a family, already pregnant, or thinking about it in the next few years, this is one of the largest single gaps in cover.
7. Mental health support is typically excluded
Therapy, psychiatric care, and mental health medication management are usually not part of a travel insurance policy. For long-term residents who already use these services or might come to need them, this is a real limit. Most comprehensive expat health plans now include mental health as standard.
8. Routine dental work is not covered
Travel insurance covers emergency dental trauma, broadly defined. It does not cover cleanings, fillings, crowns, root canals, or any planned dental work. For a long-term resident, this means dental care becomes a fully out-of-pocket category.
9. Travel insurance usually works on a pay-and-claim basis
Travel insurance is usually pay-and-claim. You pay the hospital or clinic upfront, keep the receipts, submit a claim, and wait for reimbursement. This works for a single incident on a short trip. As the basis of ongoing healthcare, it becomes a recurring administrative task. Most expat health plans in Thailand offer direct billing at major private hospitals: you show your card at the desk, and the hospital bills the insurer directly. Over a year of regular healthcare use, that difference reshapes how it feels to use your insurance.
10. The cost of waiting adds up
Every year you wait, two things work against you. The first is that health insurance gets more expensive as you get older, because age is a major factor in how it is priced. The second is that the longer you stay on travel insurance, the more likely something develops in the background that becomes a pre-existing exclusion on any future health policy. The short-term savings from staying with travel insurance usually disappear once you try to switch.
Who actually qualifies for expat health insurance in Thailand
One of the most common reasons people stay on travel insurance is the assumption that they do not qualify for anything else. Most expat health plans require the policyholder to be in Thailand for at least 180 days per year. A DTV holder doing the standard cycle, with one 180-day entry, a border run, and another 180-day entry, meets that threshold comfortably. The border run does not break the residency calculation the way many people assume it does.
For DTV holders who use Thailand as a base but travel elsewhere in the region during the year, regional plans count residency across multiple Southeast Asian countries rather than Thailand alone. That pattern still qualifies, just on a different product.
What to do if you are not sure where you fit
Start with the policy you already have. Two questions to ask: how long is each trip my current travel policy is willing to cover, and how long am I actually here for each entry? If the second number is bigger than the first, the product is not doing what most people assume it is doing.
Then look at how you are actually living. Where do you sleep most nights? Where do you go for a non-emergency doctor’s appointment? Where do you collect prescriptions? Where is your dentist? If the answers all point to Thailand, you are no longer living a trip-shaped life, and it is worth having the conversation about expat health insurance. The product exists, most long-stay foreigners qualify for it, and the conversation is much easier to have while nothing has gone wrong yet.
Travel insurance and health insurance are not substitutes. One protects your trip, while the other protects your future. The question is which one fits the life you are actually living.
