Medicare has a 2 year wait for disabled people on Social Security Disability. Did you check to see if your Dad is also eligible for Medicare extra help? Here is a link for that. I also one more link in my above post for you.www.medicare.gov/your-medicare-costs/help-paying-costs/extra-help/level-of-extra-help.html
Again...in our case, nothing is available. Some people refi homes, sell extra vehicles, sell the large home and rent or buy a small condo instead of keeping a large home.
Also, check with each utility company and ask if they have any help for elderly or disabled. Some do. Again...did not work for us, but give it a shot :) If there is a mortgage, perhaps the bank will let them refi, or delay a payment. Hope Dad is getting things moving. Big Hugs
