spousal medicaid

The social worker called me again to find out if I had all the information that I needed on the available nursing homes. I wanted to know what would happen after ninety days when my insurance coverage would run out. She told me that we could always file for medicaid. The way I understand it my state allows us to file for spousal medicaid. I'm am not that knowledgeable on this subject but the way I think I understand it is, the partner that needs medicaid would receive it.
