This is a new law, so you might have to work pretty hard to find the legalese on it. You might have to get in contact with someone at Medi-Cal, and you'll need to vet top surgeons one at a time. I have heard that some don't do insurance at all, but I wouldn't know. I paid for my surgery out of pocket.
Be prepared to jump through a lot of hoops and take quite a bit of time to reach your goal. But I think it's worth it if you don't have to shell out thousands and thousands of dollars.
