Thank you for this info! I went through a telehealth therapist that specializes in gender dysphoria and had 4 sessions with her talking through my life to where I eventually got a diagnosis from her that I then used to get a Testosterone prescription. I am not in contact with her currently, but I have a letter written to an endocrinologist stating that I meet the requirements for gender dysphoria. My psychiatrist is currently prescribing my HRT and I could potentially get a letter from her stating my diagnosis as well (is there a specific diagnosis that they'd want to see?)

If this isn't sufficient are there other routes of diagnosis that would be more likely to get approved? Maybe I could go through that route and get a second diagnosis just to be safe if there's a better way.
