Cpt code doppler ultrasound pregnancy8/29/2023 ![]() ![]() ![]() ![]() A four-chambered heart could be identified in 52% of patients in the eighth week (n = 12 of 23), improving to 80% (n = 36 of 45) in the 10th week and 98% (n = 57 of 58) by the 11th week. CD assisted with definition of cardiac anatomy at all GAs. There was stepwise improvement in image resolution of the fetal heart in those pregnancies that presented at later gestation for assessment. Very early FE was performed in 202 pregnancies including a total of 261 fetuses, with 92% (n = 241) being reassessed at greater than or equal to 18 weeks' GA. Transabdominal scanning was used in all cases, and transvaginal scanning was used additionally in most at less than 11 weeks' GA (n = 103 of 117 ). Fetal cardiac anatomy was assessed both in real time during FE and additionally offline by two separate reviewers. All underwent two-dimensional (2D) cardiac imaging combined with color Doppler (CD) assessment, and all were offered second-trimester fetal echocardiographic evaluations. Pregnant women were prospectively recruited for first-trimester FE. (2017) states that early fetal echocardiography (FE), performed at 12 to 16 weeks' gestational age (GA), can be used to screen for fetal heart disease similar to that routinely performed in the second trimester however, the efficacy of FE at earlier GAs has not been as well explored, particularly with recent advances in ultrasound technology. Newer technology including endovaginal transducers can obtain images of the heart as early as 12 weeks gestation (AHA, 2018). Some forms of congenital heart disease may even be recognized during earlier stages of pregnancy (AIUM, 2013). With current technologies, accurate segmental analysis of cardiac structures and blood flow across valves, shunts, and the ductus arteriosus is possible with a conventional transabdominal approach by 16 to 18 weeks of gestation.Īccording to the American Institute for Ultrasound in Medicine (AIUM), fetal echocardiography is commonly performed between 18 and 22 weeks’ gestational age. Pregnant women receiving selective serotonin reuptake inhibitors (except paroxetine) orĪetna considers fetal magnetocardiography experimental and investigational because its effectiveness has not been established.ĭefinition of fetal cardiac structures is currently possible at 12 weeks of gestation with the use of vaginal probes with high-resolution transducers.Gestational diabetes even if requiring insulin after the first trimester or.As a screening test in advanced maternal age or.Tachycardia other than sinus tachycardia or heart block orįetal surveillance (e.g., congenital heart block) in mother with documented diagnosis of Sjögren’s syndrome. Frequency of testing: Doppler fetal echocardiography may be repeated every 1 to 2 weeks starting at 16 weeks gestation continuing through 28 weeks gestation, then every other week until 32 weeks gestation to detect fetal (congenital) heart block.Īetna considers fetal echocardiograms experimental and investigational for all other indications including the following (not an all-inclusive list) because their effectiveness for these indications has not been established.Structural heart disease with a suggestion of hemodynamic compromise or.A ductus arteriosus dependent lesion or.When the initial screening study indicates any of the following: When other structural abnormalities are found on ultrasound orĪetna considers repeat studies of fetal echocardiograms, Doppler and color flow mapping medically necessary for any of the following: ![]()
