My elderly friend needs to be in a physical therapy rehab that will cater to her. Who do I call?

To quote "send" from other thread (thanks!)
CMS.gov defines homebound.
HOMEBOUND
"Normally unable to leave home unassisted. To be homebound means that leaving home takes considerable and taxing effort. A person may leave home for medical treatment or short, infrequent absences for non-medical reasons, such as a trip to the barber or to attend religious service. A need for adult day care doesn't keep you from getting home health care."

The doctor ordered in-home PT for my mother. What exactly does "home bound" mean? My mother doesn't drive (I provide transportation). When the doctor said he could prescribe PT for her knee, I quickly asked, "Can that be in-home?" "Of course," he said. (I didn't want to drive her to PT appointments.)

If you want Medicare to pay for the physical therapy, she needs to have an "event" that precedes the doctors order. Otherwise, it will be paid by her.

Doc order for in-home therapy only happens when doc certifies her "home bound"

A rehab that will cater to her? What exactly do you mean?

If your friend just needs physical therapy, doctor can write a script for some to come to the home.
