My dad has dementia and needs constant care. What can I do if Medicare declined him and won’t pay?

go to medicaid office and if they deny him ask for a fair hearing and explain to them that you can't maintenance him/nor pay for a nursing home. also call your local councilman/senator/politician and ask for help. talk to his doctor or social worker at he hospital where he get medical treatment and explain them your dad's situation to see what's happens. good luck
