Sunday I had to call 911 when Mom fell and I couldn't get her up. She did not hurt herself in the fall, but she was both dehydrated, low on sodium, and has a bad UTI. She will probably need to be transferred from the hospital to a rehab nursing facility. My question is this. As her POA am I responsible for unpaid bills from the hospital? ie. radiology, specialists etc. I unfortunately have all her money in a joint account. When that is gone, am I still held responsible?
