unplanned hospitalisation

Hi

I have a guest (brother -in -law), visiting from Bangladesh. He has
a known heart condition. Within a couple hours of arriving at the
house, he was sitting down to a meal. Halfway through it he lost
consciousness. We called 911. He regained consciousness within a
minute or so. The paramedics came, checked him out, and said all
tests came out normal but strongly urged that he should be taken to
the nearest hospital for further tests. He was moved by ambulance to
Anaheim Memorial Hospital. This is not a community hospital. There they ran a battery of tests, including blood tests, urine tests and CAT
scan. They advised to keep him overnight. In the morning they ran
further tests, although the previous days test results were normal.
When I asked to take him home and not run anymore tests, they said
that we would be acting " against medical advice", and that they would not extend any discounts which they would previously extended.
The patient does not have any health insurance, and no money to pay
for his bills. They insisted that I make a $500 deposit towards
the $3500 bill which has increased manifold by now. The lady said
at the time that this did not make me liable for any bills, and
that I could have this money back when the bill was settled. I
have given them my credit card to charge that $500. He was released by the hospital that evening. He was found to have had dehydration. So far I have not signed anything and
made it clear to them that the patient is responsible for all his
expenses. The 'deposit' was a loan to my brother in law, as he had no cash with him. His closest relative (a daughter) lives in Indiana.

Could you advise me on any liabilities I may have inadvertently
signed up for by making the [$500] deposit? Please advise me on
what my conduct should be when the bails come.

If you signed the payment forms you could be liable. Review what you signed closely.

But you can still dispute it and argue they misled you in the middle of an emergency.

If any witnesses could back that up, it would be even more helpful.
