He was traveling, was taken ill, went to emergency, survived his surgery but had to be put in hospice due to colorectal cancer, stage 4. He could not travel back home and consequently passed away out of the country. We paid for his medical expenses on our credit card and insurance has reimbursed us for the hospital but not hospice.
Have you contacted the foreign to ask if they are willing to waive or reduce their fees. There may be charitable funds to pay for this.
Why did you assume responsibility for the payments rather than have them charged to Dad's account?
This is no longer a help to you but there are often charities who are willing to help return a seriously ill patient to their home.
Additionally if you are still stuck with the bill you my be able to work with your CC company for a reduction or at least take a deduction on your taxes if you assumed responsibility for Dad's care once he became ill which it sounds as though you dad. So sorry for your loss and the current difficulties you are experiencing.
If all else fails, it seems only right that your CC charges be paid back directly from his estate, when it comes time to settle up. I'm sure he would have aggreed.
I'm glad your father did get his vacation. But this is awful for the family - I'm so sorry for your loss, and for this additional worry at such a sad time.
