It will depend on which state your father resides in.
Some states accepted the Medicaid expansion. Even with that there are different guidelines.
In NV where I worked on Medicaid claims, it was based on if you had an income and what that level was. It did not take into consideration of savings or if you owned a home etc.
In PA where I am now the guidelines are different and it is income level and they do consider savings and other finances.
My advice is if you can go on the Medicaid website for the state you are in. All of the guidelines and if a person qualifies are there as well as the application. Also you can call the state Medicaid office for assistance.
