Insurance deductible and other necessities

My mother was a victim of assault and armed robbery on Jan. 10th 2023 at 4pm trying to access an atm at a u.s. bank on 26th and Wisconsin. The person took advantage of a 66 year old disabled woman. Tried to take the money from her hand and pulled her out of her wheelchair. They broke her right hip while trying to get away leaving her In The middle of the street. She's going into surgery tomorrow January 11th, 2023 and has Medicare only. She to go Into a rehabilitation center after that and the deductible is 1,600. I'm her only son and I'm doing everything I can to help but I don't have this kind of money on hand. Anything will help, I greatly appreciate you!
