Medicaid & Revisions

I have KY Medicaid. It paid for my RNY surgery back in 2006. I am now looking into having a revision to a DS. Does anyone have any experiences with medicaid paying for your revision? Does anyone know if it will pay for a revision? I called the 1800 # and the only Insurance code I had was for DS and she said it was covered.. That eases my mind, however, I worry that it will not cover a revision especially since it paid for my original RNY.
