Will medicaid pay for a Brazilian butt lift?

When I was a child I crushed my coccyx since then it has been very painful for me to sit down. However in May of 2014 I had gastric bypass surgery and I've lost over 130 pounds now I have excruciating pain when sitting in the tub because it seems like that bone is exposed. In order for me to take a bath in the tub I have to be on my knees or lay, but even laying is extremely painful. When I'm in bed I can only lay on my side or my stomach because laying on my back is painful on my coccyx.
