How do I get my dad's OT, PT and ST restored during hospice?

In general and in most circumstances PT/OT are not a part of end of life care. There are times when they are a part of it. Check with the doctor.

People in hospice are waiting to die. The only help they get, is to be make them as comfortable as posible. No rehabilitation therapies or treatments are provided. They are supposed to have exhausted all medical resources to cure them.

I see nothing about Dementia involved. This is OPs first post.

If Dad is on Hospice he does not receive therapy. Like said maybe to help with contractures or atrophy.

The short answer is that you need to make an appeal for coverage.

Therapies (ST, OT and PT) in hospice are for symptom control, not to restore a patient to previous functional levels.

Dad is in a NH, yes? Is he there in Rehab or as a Long Term Care resident?

You find the head of rehab and ask her/him to appeal the stoppage.

Are you dad's POA for healthcare? Unless dad is incompetent, the folks at the NH will talk to DAD about this stuff and expect him to communicate it to you. Was it Dad who signed on to Hospice? Did you two discuss this? Is he perhaps tired of doing therapy?

Have you had a care conference yet? All the therapists, DON and Social Worker will attend and they should review dad's plan of care. It's an excellent time to ask these questions, ask them to keep you informed.

Can you not say why he was put on hospice are?

Why is your dad on Hospice if he needs those therapies?

You can make a case for PT to prevent contractures, but hospice is about comfort care, not restoring previous levels of functioning.
