In fairness he did not come to LA for his medical care. He had a disk operation on his neck by a “celebrity surgeon” who may have “botched” the operation. Hallyday flew to LA for business/personal reasons soon after the operation and then collapsed once there.
Only to point out that this is not a case of medical tourism - it’s a case falling ill while traveling.
Halliday came to the US to fix the problems caused by the French surgeon. His agent said:
“It seems the Americans fixed things that they found that were very badly done.”
Many many foreign rich and connected from countries with govt run medical systems come here to get fixed.
