Molina Healthcare Ohio (Medicaid) Insurance qualifications !

Hello Everyone! I'm so glad I found this forum! I've been putting a TON of thought into bariatric surgery and have been trying to figure out how I was going to pay for it on my own. I decided to see what my insurance would help me with ( Molina Medicaid) I'm glad I did!! I have a couple questions and any advice is GREATLY appreciated! Do I need to call my insurance first for any reason? Should I just make an appointment at the bariatric clinic or do I need to go to my PCP? My BMI is 43 and I haven't been 'diagnosed' I know that I have sleep apnea and high blood pressure. I had complications with my pregnancies due to high blood pressure and it's stayed high. I am in Columbus, OH so I am open to advice on bariatric drs/locations! thank you!!
