Here is a SCAM that anyone (in USA) could become the next victim. If you happen to go to emergency in an hospital , you can be charged with a “trauma fees”.Charges ranged from $1,112.00 at a hospital in Missouri to $50,659.00 at a hospital in California.

At San Francisco General Hospital, the $30,206 higher-level trauma response fee, which increased by about $2,000 last year, was approved by the San Francisco Board of Supervisors

Example:
The hospital charged Sulvetta a $15,666 trauma response fee, a hefty chunk of her $113,336 bill. Her insurance decided that the hospital fees for the one-day stay were too high, and — after negotiations — agreed to pay only a charge it deemed reasonable. The hospital then went after Sulvetta for $31,250.

Trauma centers argue that these fees are necessary to train and maintain a full roster of trauma doctors, from surgeons to anesthesiologists, keeping them on-call and able to respond to medical emergencies at all times.
Zuckerberg San Francisco General Hospital spokesperson Brent Andrew defended the hospital’s fee of over $15,000, even though Jeong-whan didn’t require those services.
“We are the trauma center for a very large, very densely populated area. We deal with so many traumas in this city — car accidents, mass shootings, multiple vehicle collisions,” Andrew said. “It’s expensive to prepare for that.”
