When had my surgery I went to my prim care Dr. at the time and came clean, figured he's a Dr. so.... Then told him what my surgeon "Chettawut" needed, he ordered the tests, had x-rays and blood work covered, and I paid my co-pay. Now is not the time to be shy with a doctor, be frank with tell him what is up and be concise and to the point. I was nervous as hell too when I went and told him as I hadn't told him I was trans, lol the look on his face lol, anyway he said my x-ray was to check for pneumonia, and the blood work was to test for my general health and auto immune disorders. It went smoothly.
