Support Husband's Rehab After Stroke

My husband had a hemorrhagic stroke and has been in the hospital for over 30 days. He needs to go to rehab and his insurance is not covering the rehab that he needs! He is completely paralyzed on his left side. And left side vision loss. He needs extensive rehab that his insurance is not covering so we have to pay out-of-pocket. Please help me pay for his rehab!
