Aetna considers ultrasounds not medically necessary if done solely to determine the fetal sex or to provide parents with a view and photograph of the fetus. Aetna considers detailed ultrasound fetal anatomic examination experimental and investigational for all other indications including routine evaluation of pregnant women who are on bupropion Wellbutrin or levetiracetam Keppra , pregnant women with low pregnancy-associated plasma protein A, and pregnant women who smoke or abuse cannabis.
There is inadequate evidence of the clinical utility of detailed ultrasound fetal anatomic examination for indications other than evaluation of suspected fetal anatomic abnormalities. Detailed ultrasound fetal anatomic examination is not considered medically necessary for routine screening of normal pregnancy, or in the setting of maternal idiopathic pulmonary hemosiderosis.
Ultrasonography in pregnancy should be performed only when there is a valid medical indication. ACOG stated, "The use of either two-dimensional or three-dimensional ultrasonography only to view the fetus, obtain a picture of the fetus, or determine the fetal sex without a medical indication is inappropriate and contrary to responsible medical practice.
Indications for a first-trimester ultrasound performed before 13 weeks and 6 days of gestation include:. This recommendation is based primarily on consensus and expert opinion Level C.
ACOG stated that it may be possible to document normal structures before 18 weeks of gestation but some structures can be difficult to visualize at that time because of fetal size, position, and movement; maternal abdominal scars; and increased maternal abdominal wall thickness.
A 2nd or 3rd trimester ultrasound examination, however, may pose technical limitations for an anatomic evaluation due to suboptimal imaging, and when this occurs, ACOG recommended documentation of the technical limitation and that a follow-up examination may be helpful.
ACOG uses the terms "standard" also called basic , "limited," and "specialized" also called detailed to describe various types of ultrasound examinations performed during the 2nd or 3rd trimesters.
A standard ultrasound includes an evaluation of fetal presentation, amniotic fluid volume, cardiac activity, placental position, fetal biometry, and fetal number, plus an anatomic survey. A standard examination of fetal anatomy includes the following essential elements:. A limited examination does not replace a standard examination and is performed when a specific question requires investigation e. A limited examination may be performed during the 1st trimester to evaluate interval growth, estimate amniotic fluid volume, evaluate the cervix, and assess the presence of cardiac activity.
A detailed or targeted anatomic examination is performed when an anomaly is suspected on the basis of history, laboratory abnormalities, or the results of either the limited or standard examination. Other specialized examinations might include fetal Doppler ultrasonography, biophysical profile, amniotic fluid assessment, fetal echocardiography, or additional biometric measurements. Specialized examinations are performed by an operator with experience and expertise in such ultrasonography who determines that components of the examination on a case-by-case basis.
Rather, this scan is necessary for a known or suspected fetal anatomic or genetic abnormality i. AMA, diabetic, fetus at risk due to teratogen or genetics, abnormal prenatal screen.
Thus, the SMFM has stated that the performance of this scan is expected to be rare outside of referral practices with special expertise in the identification of, and counseling about, fetal abnormalities SMFM, ; SMFM, Once this detailed fetal anatomical examination is done, a second one should not be performed unless there are extenuating circumstances with a new diagnosis. The SMFM has stated that it is appropriate to repeat the detailed fetal anatomical ultrasound examination when a patient is seen by another maternal-fetal medicine specialist practice, for example, for a second opinion on a fetal anomaly, or if the patient is referred to a tertiary center in anticipation of delivering an anomalous fetus at a hospital with specialized neonatal capabilities.
A focused ultrasound assessment is sufficient for follow-up to provide a re-examination of a specific organ or system known or suspected to be abnormal, or when doing a focused assessment of fetal size by measuring the bi-parietal diameter, abdominal circumference, femur length, or other appropriate measurements SMFM, Amniotic band sequence refers to a highly variable spectrum of congenital anomalies that occur in association with amniotic bands.
Amniotic banding affects approximately 1 in 1, live births. It is also believed to be the cause of in 10, miscarriages. The diagnosis is based upon the presence of characteristic structural findings on prenatal ultrasound or postnatal physical examination. The diagnosis should be suspected when limb amputations or atypical body wall or craniofacial defects are present, or when bands of amnion are seen crossing the gestational sac and adherent to the fetus. In a practice bulletin on screening for fetal chromosomal anomalies, ACOG has stated that patients who have a fetal nuchal translucency measurement of 3.
The atypical anti-depressants include bupropion, duloxetine, mirtazapine, nefazodone, and venlafaxine. The limited data of fetal exposure to these anti-depressants do not suggest an increased risk of fetal anomalies or adverse pregnancy events.
In the one published study of bupropion exposure in patients, a significantly increased risk of spontaneous abortion, but not an increased risk of major malformations, was identified.
In contrast, the bupropion registry maintained at GlaxoSmithKline has not identified any increased risk of spontaneous abortion, although these data have not undergone peer review. These investigators searched the Cochrane Pregnancy and Childbirth Group's Trials Register June and the reference lists of identified studies. Randomized and quasi-randomized controlled trials of Doppler ultrasound for the investigation of utero-placental vessel waveforms in 1st and 2nd trimesters compared with no Doppler ultrasound were included in this review.
Two authors independently assessed the studies for inclusion, assessed risk of bias and carried out data extraction. The methodological quality of the trials was good. Both studies included women at low-risk for hypertensive disorders, with Doppler ultrasound of the uterine arteries performed in the 2nd trimester of pregnancy. In both studies, pathological finding of uterine arteries was followed by low-dose aspirin administration.
They identified no difference in short-term maternal and fetal clinical outcomes; identified no randomized studies assessing the utero-placental vessels in the 1st trimester or in women at high-risk for hypertensive disorders.
The authors concluded that present evidence failed to show any benefit to either the baby or the mother when utero-placental Doppler ultrasound was used in the 2nd trimester of pregnancy in women at low-risk for hypertensive disorders.
There were no randomized studies in the 1st trimester, or in women at high-risk. They stated that more research is needed to examine if the use of utero-placental Doppler ultrasound may improve pregnancy outcome. Typically the umbilicord contains two arteries and one vein; however, a variation of umbilical cord anatomy may occur resulting in a single umbilical artery SUA. SUA may be an isolated finding, or associated with aneuploidy or other congenital anomalies. Prevalence depends on the characteristics of the population studied.
SUA is more common in pregancies at "the extremes of maternal age and in Eastern Europeans", as well as, in twin pregnancies 3. SUA is a finding that is found on an obstetrical ultrasound examination. SUA occurs in approximately 0. SMFM recommends further SUA evaluation to include a detailed anatomic survey by an experienced provider, and include assessment of risk factors for aneuploidy, including maternal age, results of other screening or diagnostic tests, and family history.
Three-dimensional 3D ultrasound can furnish a 3D image of the fetus. Proponents of 3D ultrasound scanning have argued that volumetric measurements from 3D ultrasound scan are more accurate and that both clinicians and parents can better appreciate a certain abnormality with a 3D scan than a standard 2-dimensional 2D scan.
In addition, there is the possibility of increasing psychological bonding between the parents and the baby Ji et al, Other more subtle features such as low-set ears, facial dysmorphia or clubbling of feet may be better assessed, which has the potential to lead to more effective diagnoses of chromosomal abnormalities.
The intra-class correlation coefficient ICC was highest for the vascular indices vascularization index VI and vascularization-flow index VFI , greater than 0. Intra-class correlation coefficient for flow index FI showed moderate correlation at 0. There was no bias between datasets.
Prospective studies are now required to identify if this analysis tool and method is sensitive enough to recognise patients with early-onset placental dysfunction. More recently, 4-dimensional 4D or dynamic 3D scanners have come on the market, with the attraction of being able to look at fetal movements. These have also been referred to as "reassurance scans" or "entertainment scans.
However, the impact of 4D scans on diagnosis and management of fetal abnormalities is unknown. Three-dimensional ultrasound appears to have been useful in research on fetal embryology. However, there is no evidence that the results of 3D ultrasound alters clinical management over standard 2D ultrasound such that clinical outcomes are improved. Whether 3D ultrasound will provide unique, clinically relevant information remains to be seen. Despite these technical advantages, proof of a clinical advantage of 3-dimensional ultrasonography in prenatal diagnosis in general is still lacking.
Potential areas of promise include fetal facial anomalies, neural tube defects, and skeletal malformations where 3-dimensional ultrasonography may be helpful in diagnosis as an adjunct to, but not a replacement for, 2-dimensional ultrasonography. Until clinical evidence shows a clear advantage to conventional 2-dimensional ultrasonography, 3-dimensional ultrasonography is not considered a required modality at this time.
Their use in fetal medicine varies with the nature of the tissue to be imaged and the challenges each organ system presents, versus the advantages of each ultrasound application. Fetal applications include all types of anatomical assessment, morphometry and volumetry, as well as functional assessment. They had successful fetal nasal bone measurement by 2D US by 4 operators. Three-dimensional volumes were recorded in the mid-sagittal plane of fetal profile by the 5th operator and examined using multi-planar techniques.
In the subsequent 3D examination, the nasal bone length could be examined in 94 cases The mean difference between the 2D and 3D measurements was 0. Limits of agreement were The authors concluded that there was significant inter-method difference between the results obtained by 2D and 3D, as well as substantial inter-observer variation in 3D measurement of fetal nasal bone length in the 1st trimester.
They stated that independent 3D measurement of nasal bone offers no additional advantages over 2D US. Kurjak and colleagues stated that an evolving challenge for obstetricians is to better define normal and abnormal fetal neurological function in utero in order to better predict ante-natally which fetuses are at risk for adverse neurological outcome.
In a multi-center study, these investigators examined the use of 4D US in the assessment of fetal neurobehavior in high-risk pregnancies.
It was revealed that fetuses were neurologically normal, 7 abnormal and 25 borderline. Out of 7 abnormal fetuses ATNAT was borderline in 5 and abnormal in 2, whereas GM assessment was abnormal in 5 and definitely abnormal in 2.
In summary, out of 32 borderline and abnormal fetuses, ATNAT was normal in 7, borderline in 22 and abnormal in 3; GM assessment was normal optimal in 4, normal suboptimal in 20, abnormal in 6 and definitely abnormal in 2. The authors concluded that 4D US requires further studies before being recommended for wider clinical practice.
The parents and families could readily understand the fetal conditions and undergo counseling; they then choose the option of termination of pregnancy. In a pilot study, Antsaklis et al evaluated the use of 3D ultrasonography as an alternative for examining fetal anatomy and nuchal translucency NT in the first trimester of pregnancy.
A total of low-risk pregnant women undergoing 1st trimester ultrasound scan for fetal anomalies were included in this study. The NT and fetal anatomy were evaluated by 3D ultrasonography after the standard 2D examination. The gold standard in this study was the 2D ultrasonography. In some of the evaluated parameters, the 3D method approaches the conventional 2D results.
These parameters are the crown-rump length CRL , the skull-brain anatomy Some of the anatomic parameters under evaluation revealed a statistically significant difference in favor of the 2D examination. During the 3D examination the nasal bone was identified in The authors concluded that the 3D ultrasound is insufficient for the detailed fetal anatomy examination during the 1st trimester of pregnancy.
An UpToDate review on "Idiopathic pulmonary hemosiderosis" Milman, does not mention the use of detailed ultrasound fetal anatomic examination. According to the Product Insert of Keppra Pregnancy Category C , there are no adequate and well-controlled studies in pregnant women. In animal studies, levetiracetam produced evidence of developmental toxicity, including teratogenic effects, at doses similar to or greater than human therapeutic doses.
Keppra should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. As with other anti-epileptic drugs, physiological changes during pregnancy may affect levetiracetam concentration. There have been reports of decreased levetiracetam concentration during pregnancy.

Focus on Obstetric Ultrasound
The CPT code book lists the required elements for all OB ultrasound codes, and gives instructions to look for all of these elements in the radiology report in order to choose a complete study code. This article summarizes the OB codes and identifies when they should be reported. The current complete OB ultrasound codes include: , , , , , , and Coding questions commonly brought forward by coders of OB ultrasound fall into two categories. First, lack of understanding of the study's technical aspects and of the terminology used in the reports often results in an inability to determine whether all the required elements are, in fact, documented. Second, there is sometimes confusion about assignment of an OB ultrasound code vs an abdominal or non-OB pelvic ultrasound code. If any of the elements are not documented, the limited OB ultrasound study should be assigned
Ultrasound for Pregnancy
A viability scan is used to check a pregnancy is developing normally is viable. It can be done transabdominally like a normal ultrasound after about 7 weeks. Before this it will be done vaginally. Before 7 weeks all they will look for is that the sac is in the uterus as they are unlikely to see a heartbeat.
This document addresses the use of maternity ultrasound in the outpatient setting. This document does not address nuchal translucency. Maternity ultrasound is considered medically necessary for any of the following:.
