I'm really happy you had a positive experience in the ER.
In 2004 I ended up in a local hospital emergency room, and when my TS past was discovered by the ER doctor, he refused to treat me! The most he would do was shoot me up with pain meds and transfer me to intensive care where I had to wait until another doctor showed up and I could be sent to surgery. Even worse, because I had been treated in the hospital chain before and identified by my SSN, the hospital attempted to put an wrist ID on my with my former male name and "M". They then tried to coax me to sign all of the authorizations and hospital paperwork in my old name. This is despite me presenting them a legal drivers license showing my new name and "F." I eventually called for the administrator and told her "If I need to sign the paperwork in that name in order for you to render life saving assistance, I'll do so, but keep in mind that "he" isn't insured, and I really doubt that my insurance is going to pay you ANYTHING if you choose to prepare all paperwork in that name." 5 minutes later she reappeared with a new hospital ID bracelet with the correct info, as well as re-done paperwork with the correct information. I really hate the healthcare around here. (Florida)
