What is the CPT code for nuchal translucency ultrasound?

Ultrasound Fetal Nuchal Translucency Measure CPT® 76813 can be performed once per pregnancy if the pregnancy is 11 to 13 6/7 weeks.

Is nuchal scan same as 12 week scan?

The nuchal translucency (NT) scan, or “12-week scan,” is an ultrasound performed in the first trimester between 11.5 weeks and 13 weeks, six days. This scan is combined with a blood test that looks at two specific hormones of pregnancy: the free-Beta hCG and PAPP-A (pregnancy associated plasma protein A).

What is cer on ultrasound?

The trans‐cerebellar diameter is the widest measurement across the cerebellum, perpendicular to the falx. Cerebellar size in millimetres correlates with gestational age up to 20 weeks and is larger than gestational age after this time.

How accurate is 12-week scan for Down’s syndrome?

Babies with Down’s syndrome are more likely to have a small or absent nose bone, with a flat profile. They often have leakage across the tricuspid valve and reverse flow in the ductus venosus. So adding in these additional markers will take the average detection rate of the standard technique of 80% up to 95%.

Can a baby with Down syndrome have a normal nuchal translucency?

A normal amount of fluid in the back of the neck during ultrasound means it is very unlikely your baby has Down syndrome or another genetic disorder. Nuchal translucency measurement increases with gestational age.

What is BPD HC AC FL in fetal biometry?

Biparietal diameter (BPD) is one of the basic biometric parameters used to assess fetal size. BPD together with head circumference (HC), abdominal circumference (AC), and femur length (FL) are computed to produce an estimate of fetal weight.

What does P90 mean on an ultrasound?

P90 means 90% of the estimates exceed the P90 estimate. It does not mean that the estimate has a 90% chance of occurring – that is a very different concept. The central limit theorem indicates that the P50 estimate has more chance of occurring than the P90 and P10 estimates.

What is the difference between 76805 and 76811?

Q Are CPT 76805 and 76811 different? Both are for fetal and maternal ultrasound evaluation, yet 76811 includes a detailed fetal anatomic exam.
