Pls help! Nonbinary breast reduction surgery

I'm not sure if this is the right space to ask, pls lmk if this is inappropriate to ask here. I'm looking to get a breast reduction, going from a 36c to hopefully somewhere in the a range. My insurance does cover it! I'm in the US and live below the poverty line (yay!😍), so I qualify for Medicaid. How does someone navigate this process? My insurance says I need to be diagnosed with gender dysphoria and I need a letter from a qualified medical professional sent to the surgery office. I live in a rural area and am concerned the one psychologist around here is transphobic. Has anyone navigated this process? It's overwhelming and I'm not sure where to start😞
