It depends on several different factors. You would need to provide specific information on your situation such as the state you live in, your household (are you married, do you have minors), specific income (yours and spouse's), specific resources (cars, bank account balances, etc) and whether or not you work. For example, if you are a single adult living in Texas with no minors you would have to receive less than $694 per month and have countable resources totaling less than $2000 in order to qualify for SSI Medicaid. Texas also has a Medicaid Buy-In program for disabled adults on RSDI who work. If you are looking at a Medicare supplement through Medicaid the limit would be $903 - this before they deduct your Medicare premium. Your best bet would be to look online for what programs are available in your state and their corresponding income limits or call your local Aged and Disabled Medicaid office for screening.
I'm 53 and am disabled. My minor child and I live on my Disability payments through the government. I am on medicare and medicaid. I live in Oregon. My disability payments are 1150/mo. My only asset is my house, which has 50,000 owed. It is in poor condition. Does the Government take my assets if I sell this before it's too late and will be condemned?
