You can call your insurance company and they can direct you. I have BCBS Highmark, I called my insurance and they sent me a Copy of the requirements, it didn't say anything about six months requirement. I have payed co-pay for almost all my pre surgery visits with Nut, surgeon, cardiologist, psych and physical therapy. I started my journey late august, I have my psych appointment on Tuesday after which my surgeon will submit documents for approval from BCBS.
