What to do when insurance denies payment for rehabilitation services and you cannot take care of him at home?

59 yr old husband hospitalized with 2nd stroke. Admitted to rehab; after 6 wks insurance quit paying saying not making sufficient gains in therapy. Patient has had many chronic problems including severe headaches, c. diff infection causing severe diarrhea, is on PEG feeding tube and urinary catheter (also had UTI) and is battling dysphagia. Therapy has been very difficult and intermittent due to all medical problems. Don't insurance companies have to also consider the medical condition of a therapy patient? Can't participate much in therapy with 'poop' running down your legs or throbbing headaches. What to do now? My experience has been that the elderly and disabled are not given the same medical consideration as younger and/or non handicapped individuals.
