Totally agreeing with everything Sue has posted.
A meeting should be scheduled for your brothers family/caregivers prior to his discharge from Rehab. If not ASK FOR ONE NOW.
At that time all of his equipment needs should be discussed. Hopefully one of the therapy staff will have made a home visit to evaluate equipment needs including, bath/shower bench,sliding board, sleeping needs (hospital bed, trapeze), toileting needs (bedside commode, elevated toilet seat, grab bars in bathroom). Medicare will rent a wheelchair for him until his powerchair is delivered. This should be ordered by the rehab team prior to discharge. If he will be using the powerchair, how will he get into the community? His caregivers will need to be able to contact local van transport or install a lift in their pov. Also Homecare visits may be initiated including, RN, OT, PT and maybe a Home Health Aide.
I don't know if guidelines have changed, but Medicare used to only pay for one of the following.. walker or wheelchair. If the patient already had a manual chair and doctor found it necessary for patient to use a powerchair.. it was a battle but medicare will do it. I don't think I have ever had medicare pay for two w/c simultaneously.. most of the time the family would purchase a manual chair while medicare paid for the powerchair. We used to tell patients to let medicare cover the more expensive item, which was the wheelchair.
Hope this makes sense... dealing with medicare is always confusing.
