Can I get a doctor to come to my home?

I live in Chicago it's very hard for me to get around due to nerve damage in my back. In April or May of this year I had a doctor that was coming to my home but there company went out of business and my doctor now works at U of C. Now no one is coming to see me. I'm 69y I have Nerve damage in my back and it's really hard for me to get around .I'm not on any Med's beside the pain med I take for my back. it's getting really hard for me to get around these days so I was praying that it would be somehow possible for me to get a doctor back to the house again. I'm on SSI and I also have Medicare Blue cross Blue shell . would it be possible for me to get a doctor to come back to my home?
