Medical evacuation is the component of a travel policy with the highest potential cost per claim. Understanding how it is priced explains why limits differ so widely between products.
The cost driver is the aircraft and crew
A medical evacuation may require a dedicated aircraft configured as an intensive care unit, with a physician and nurse accompanying the patient.
Long-distance movements can involve multiple fuel stops, crew duty limits and permits for each country overflown, all arranged at short notice.
Because these are chartered rather than scheduled services, the cost of a single movement can reach a very large sum, which is why policy limits are stated explicitly.
Destination determines the exposure
Cover priced for a region with good hospitals nearby carries a different expected cost from cover for a remote area with the nearest suitable facility far away.
Insurers therefore band destinations, and the bands reflect medical infrastructure and distance rather than any general assessment of the country.
Regions where local treatment is entirely adequate generate few evacuations, while remote areas generate expensive ones even for moderate injuries.
Repatriation is a separate decision
Evacuation moves a patient to appropriate care, which may be a regional hospital rather than home, and stabilisation usually comes before any long flight.
Repatriation to the home country happens when the patient is fit to travel and is a distinct benefit with its own conditions.
Policies differ on who decides, and the better-defined wordings state that the insurer's medical team makes the call in consultation with the treating physician.
Assistance capability affects the outcome
The practical quality of this cover lies in the assistance company behind it, which locates facilities, arranges transfers and guarantees payment to hospitals.
Hospitals in many countries require payment or a guarantee before treatment, so an assistance provider able to guarantee directly changes what happens on the ground.
A high stated limit with weak assistance behind it is worth considerably less than a moderate limit with a capable network, though only the limit appears in comparisons.
What travellers can check
The stated limit, whether search and rescue is included, and whether the activities planned are covered are the three points that determine whether the cover fits the trip.
Search and rescue is frequently excluded or capped separately from medical evacuation, and in remote regions it is the more likely cost.
Terms and requirements differ by insurer and jurisdiction and change over time, so the current wording of the specific policy is the only reliable source on any individual point.
