When I came out to my PCM almost 15 years ago as MTF, VA offered me gender affirming care (after psyche evaluation, suicide is a real problem in our population) and assigned me to a single PCM in the Women's Clinic. I find that in the VA system the patients are almost never seeing the same care giver, always someone new. The turnover is atrocious in my experience.
She always has a young doctor in tow, whether in person or on video/audio appointments. I use secure messaging to the clinic too and am not afraid to ask about changes to my regimen. Early on the endocrinologists got involved, always 2 at each appointment. After that 1st year PCM and I jointly consider where I am and where I feel I need to go. I've learned to not be shy when I have ideas about meds and dosages, its my life after all.
VA has limits to what can be offered. I'm hoping the current Executive Officer won't impact the VA support to our community. HRT for me was Spironolactone first, then Estradiol 6 mos. later. This is where you might get the feeling that medicine is a practice and we are research subjects. I send my PCM research about other healthcare systems HRT programs, which she seems to welcome. An example was progesterone. She is limited by what the VA approved and must be able to justify her medical opinions. For 2-3 years she said there wasn't a definitive study available to support it, then after year 3 HRT she added it. VA won't do any surgeries, but they will help with prosthetics (and bras to fit them), life test support and therapy, HRT and voice coaching.
By the by, the progesterone seems to have helped round out my breasts. I say it definitely has, but I'm sure I'm biased. I wear the same bra sizes but the cups are well filled out C's. There's nothing scientifically objective about how you feel, but visual results are clear evidence.
All I'm trying to convey is that the VA doesn't specialize in gender affirming care, but for the most part the VA doctors that volunteer to support us are maybe not the most experienced, yet they are well meaning. If you find yourself up against it, ask for a referral to community care.
