A Border Patrol Agent on Univision said that the child injured from falling off the border wall, as shown in the recent video, had to be transported by helicopter from Yuma to Phoenix. The cost of transport wasn't mentioned, but I found this:

"A Scottsdale woman was billed $64,620 for an air-ambulance flight. Her husband was stabbed in the head and flown from a Yuma hospital to St. Joseph's Hospital in Phoenix."
