Can someone help me read my fetal ultrasound bill? There were two fees, but no doctor did the exam.

Correct. Technologist does study. Doctor reads study. You get billed for reading and technical fee separately.
Doctor. A doctor did read your ultrasound, even if you didn't meet that person. An ultrasonographer usually takes the images, and a doctor may or may not be in the room for that part, but if they are not there, they review the images later and decide whether the exam is normal or not, and make recommendations for follow-up if necessary.
