It varies based on where you live. I know that Kaiser Permanente HMO on the West coast covers transgender services, including hormones and surgery. It is listed with all the specifics of the coverage (routine physical, eye exam, prenatal, bone density CT screening, infertility, transgender services, etc.). In theory, I should have a $20 co-pay for "Transgender Services," a $20 co-pay for "Day Surgery Transgender," and a $100 co-pay for "Hospital Inpatient Care Transgender." But Kaiser isn't available everywhere, and possibly their other regions have different coverage.
