Whats the approval process for medicaid in Wisconsin.

Hi, I was wondering if anyone knows the approvel process for medicaid and medicare, I have the white forward card Im not sure if that helps any. I live in Wisconsin. I am just wondering about a time frame and how the process works with both the insurance and the steps. I am signed up for the informational seminar, for September 14th. My Primary Care Doctors, Suggest I should have the surgery and I agree. They said they were going to send whatever documents they need to. and are backing me up 100%. I am having health issues and Im on disability already for a bad back. I know that losing all this weight can greatly improve my quality of life. Im sure they are going to tell me more at the seminar but since talking with my dr.s I cant stop thinking about this, im feeling very hopeful. Thank you for any information. Also I would love to hear stories of success with the surgery. Thanks again and God Bless.
