How can I move my dad into assisted living when he has a tremendous amount of debt?

I am new to this. My father has pushed me (only child) and all his siblings away for years. He has declined tremendously over the past 6 months and has asked me to get him into Assisted Living. He has wracked up a tremendous amount of debt that I know needs to be paid off. His pension and SS will be enough to cover Assisted Living. But if I budget his debt then I cannot afford a decent place for him. I feel stuck and know time of of the essence. He is going blind, had Diabetes, Possible return of cancer (will know soon), a fall risk due to neuropothy and incontinence. Any information would be greatly appreciated. He has a neighbor helping him at home, but she isn't a nurse.
