Another SCTI customer racked up a $110,000 medical bill in the Pacific Islands after tripping and falling down a flight of steps, and injuring their hip.
Nearly half of the top 10 claims in 2017 were made while in the United States, which is renowned for having some of the highest medical care costs in the world.
SCTI Chief Executive Chris White said some hospitals in the United States may request a large deposit before they will even start providing treatment.
"This is one of the key areas where having travel insurance is important. Our emergency assistance team can provide payment guarantees to hospitals, keep immediate family advised of the situation and coordinate emergency medical evacuations," he said.
"They're available 24 hours a day, seven days a week, no matter where you are in the world.
"New Zealand's public healthcare system means we generally don't have to worry about the financial cost when we get injured or sick, but this isn't the case overseas. It doesn't take long for the bills to reach eye-watering amounts — it can cost up to $US50,000 a day for intensive care treatment at a US hospital."
White said the most expensive medical claims list showed the importance of buying travel insurance before heading overseas.
"The average price of a Southern Cross Travel Insurance policy can be as little as the cost of a coffee a day so it's an affordable one-off payment that could end up saving you tens of thousands of dollars."
