What are my responsibilities to pay my mother's medical bill? She passed away in October 2010 and the funds are running out but the bills keep on coming in. Medicare has paid but Horizon is next to impossible to deal with. She spent over 40 days in the hospital and did not use the rehab services but all are still billing for them. They insisted onkeeping her even though they had to have known that her condidtion was terminal. What do I do when the money runs out?
