What to look for on the first trimester ultrasound?
First trimester ultrasonic scans may show ‘soft’ markers for chromosomal abnormalities, such as the absence of fetal nasal bone or an increased fetal nuchal translucency (back of the neck) to enable detection of Down syndrome fetuses. While your sonographer takes measurments they will explain what you are looking at.
What is the CPT code for an ultrasound?
ultrasound can be performed to confirm dates (report one of the following CPT codes: 76801 [plus 76802 if more than one fetus] if a complete ultrasound has not yet been performed, 76815 or 76816 if a complete ultrasound was done
