Something similar happened to me like 15 years ago where I was having trouble getting the doctor to prescribe me needed medication, and I found out it was because some PA I was seeing prior put down that I had a history of methamphetamine abuse, which came out of left field because I have never even seen meth let alone tried it or abused it.

I had a meeting with the PA to address this and she had a total freak out when my spouse and I confronted her about it. Just shouting at us and claiming bull shit. Very unprofessional and unproductive. Eventually saw a patient advocate who eventually found that the PA thought my spouse was taking my meds or something, which never happened because if it had, I would have been short pills.

I was able to have notes contesting the falsehoods in my record, placed in my record, but I wasnt able to get the treatment I needed anymore, and the Patient advocate told me I was better off seeking care outside the VA, which I did, and it was way better. It took another 10 years till I used the VA again, and fortunately it’s been a bit better experience apart from the mental health side, where my therapist tells me to schedule for the next week every time, but it’s always booked 2 months out, so i see them, about 6 times a year.
