LA Care - Medi Cal HELP!, Los Angeles Area

Hello, NEW HERE! Been looking into getting WLS & currently have LA Care Medi-Cal....I can choose different plan providers such as anthem, care 1st and Kaiser...but first, anyone get lucky with LA Care in getting approved for surgery? If not, any one get lucky using the other plan providers with MEDI-CAL? Been trying to search for answers for months...(p.s. I did call LA Care they say they will cover if deemed "Medically Necessary"....i feel that they might BS me with some crap that they will say no to the surgery) 

Anthem Blue Cross with AltaMed as the medical group for them was the winning combination for me.
