I am living with and caring for my 92 year old Grandfather who has bone cancer. For some reason he never got Medicare part A, although he does have part B. He has Blue Cross also, but they recently stopped approving any rehabilitation stays that he has needed after being in the hospital. They also stopped covering any home health besides a short stint of home PT and OT. What can I do? As far as I know he can only apply during an enrollment period at the end of the year, but he needs it now.
