Hi, anyone know any helpful charities for medical deductibles?

My father is 80 and has to have back to back surgeries... for cancer and heart issues... but the deductible were insane... my mother is mega depressed about it.. It is only a few k, but with medicines, and nurses it is hard to pay down.. so I was wondering if there was a bank or charity that could help.. i dont mind if it was a loan, i just dont want my father departing and leaving us with mega bills..

any suggestions would be welcomed thanks and Bless eberyone...
