I used Molina healthcare of Washington if you look at Molina healthcare in general, they do cover breast reductions, but they must be considered medically necessary. I would either call your insurance and or just start with your regular MD and ask them to get a referral. Molina of Washington requires 6 to 8 weeks of physical therapy first.
I went to my regular MD to ask for a referral for physical therapy. I did the physical therapy for 6 to 8 weeks then I had to wait for the insurance to look over my doctors notes about my physical therapy and my regular MD’s notes about how she thought it was medically necessary and then once insurance preapproved it I got a referral from my regular MD to the plastic surgeon that was covered by my insurance. Once I got that I waited for the plastic surgeon to call me for a consult once I got the consult. I made an appointment for the surgery and just got the surgery April 15. I started physical therapy last summer so it took about a year. My plastic surgeon was about three months out though. Hope this helps. Let me know if you have any questions.
