Why Your Home Coverage Won't Follow You
Most domestic health plans, including U.S. employer coverage and Medicare, simply don't extend to treatment received abroad, leaving movers who assume otherwise exposed to the full cost of foreign medical care. International or expat health insurance exists specifically to fill that gap -- and unlike travel insurance, built for short trips and emergency-only coverage, it functions like a genuine long-term health plan: doctor visits, hospital stays, prescriptions, and often preventive care.
The Line Between Travel and Expat Coverage
Travel insurance and international health insurance are not interchangeable, despite frequently being marketed as similar. Travel insurance generally excludes routine care, ongoing conditions, mental health support, and maternity care beyond genuine emergencies. Expat health insurance, by contrast, is built for people living abroad for a year or more, and typically includes routine and preventive care alongside emergency treatment. Most insurers pay providers directly, or reimburse the policyholder after treatment, depending on the specific plan.
What Actually Matters: Evacuation, Networks, and Exclusions
A handful of policy details tend to matter more than headline premium cost. Emergency medical evacuation can run well over $100,000 from remote locations -- a benefit that alone justifies international coverage for many expats, since few people could absorb that cost directly. Provider network quality matters just as much as coverage limits: insurance is of limited use if local doctors and quality facilities don't actually accept it, making it worth researching the real provider network in a specific destination rather than a generic coverage map.
Pre-existing conditions are another common source of unpleasant surprises. Many plans impose moratorium periods of 12 to 24 months before covering a pre-existing condition, and some exclude specific conditions permanently -- assuming a condition is automatically covered, without confirming it during the application, is one of the more consistently reported mistakes among expats filing claims.
The US Coverage Question
For expats who anticipate needing care in the United States -- whether during visits home or as a future return destination -- the decision of whether to include US coverage is a significant one. Adding it can double a policy's premium, while excluding it means any care received in the US comes entirely out of pocket, given how much more expensive US healthcare typically runs compared to other developed countries.
Costs Vary Enormously by Destination
The cost of routine healthcare -- and therefore insurance pricing -- varies dramatically by country. A routine doctor's visit in the UAE might run roughly $65 to $80, compared to as little as $2 to $8 for the same visit in Thailand, or $50 to $75 in Spain. Popular expat destinations with higher-cost healthcare systems generally carry correspondingly higher insurance premiums, which is worth factoring into overall cost-of-living comparisons between countries, not just insurance shopping in isolation.
What to Actually Compare Before Choosing a Plan
Beyond price, the more useful comparison points are: whether the plan covers the specific country or countries you'll actually be in, how pre-existing conditions are handled, whether evacuation coverage extends to your home country or only the nearest adequate facility, and whether the plan integrates with telehealth options for routine care that doesn't require an in-person visit. A plan that looks comprehehensive on a marketing page can still leave meaningful gaps -- reading the actual policy document, not just the summary, remains the only reliable way to know what's covered before it matters.
