Official Description

Doppler echocardiography, fetal, pulsed wave and/or continuous wave with spectral display; follow-up or repeat study

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 76828 refers to a specific type of diagnostic imaging procedure known as fetal Doppler echocardiography. This procedure utilizes both pulsed wave and continuous wave Doppler techniques, accompanied by a spectral display, to assess the cardiovascular health of a fetus during pregnancy. The primary purpose of this echocardiography is to monitor and evaluate the unborn baby for potential cardiovascular anomalies. Such evaluations are particularly critical in cases where there is a known family history of congenital heart disease, or when an obstetrician has identified an abnormal fetal heart rhythm during routine examinations. Additionally, this procedure is indicated when anomalies of the heart or other major organ systems have been observed in previous ultrasounds, or if the mother has conditions such as Type I diabetes, or has been exposed to medications during pregnancy that could adversely affect fetal heart development. Abnormal results from an amniocentesis may also warrant this follow-up study. The procedure can be performed using either abdominal or transvaginal ultrasound techniques. In the abdominal approach, a gel is applied to the abdomen, and a transducer probe is moved across the skin to capture images from various angles. Conversely, the transvaginal method involves the insertion of a transducer into the vagina to obtain clearer images of the fetal heart. The Doppler technique is integral to this procedure, as it allows for the evaluation and measurement of blood flow through the heart's chambers and valves, providing critical information about the heart's function. This includes assessing the volume of blood pumped from each chamber with each heartbeat and identifying any abnormal blood flow patterns within the heart. Furthermore, the procedure can help detect structural anomalies, such as defects in the atrial or ventricular septum and issues with the heart valves. For initial complete studies, the CPT® Code 76827 should be used, while CPT® Code 76828 is designated for follow-up or repeat studies.

1. Indications

The fetal Doppler echocardiography procedure, represented by CPT® Code 76828, is indicated for several specific clinical scenarios, particularly when there are concerns regarding the fetal cardiovascular system. The following conditions may warrant this follow-up or repeat study:

  • Family History of Congenital Heart Disease - This procedure is indicated when there is a known family history of congenital heart defects, which increases the risk of similar conditions in the fetus.
  • Abnormal Fetal Heart Rhythm - If an obstetrician detects an irregular fetal heart rhythm during routine examinations, a Doppler echocardiography may be necessary to further evaluate the heart's function.
  • Previous Anomalies Detected - The procedure is indicated when anomalies of the heart or other major organ systems have been observed in prior ultrasounds, necessitating closer monitoring.
  • Maternal Health Conditions - Conditions such as Type I diabetes in the mother can affect fetal heart development, making this echocardiography essential for assessing potential impacts on the fetus.
  • Medication Exposure - If the mother has taken medications during pregnancy known to affect fetal heart development, this procedure may be indicated to evaluate the fetus's cardiovascular health.
  • Abnormal Amniocentesis Results - An abnormal finding from an amniocentesis may prompt the need for a follow-up echocardiography to assess the fetal heart for any potential issues.

2. Procedure

The procedure for fetal Doppler echocardiography, as described by CPT® Code 76828, involves several key steps to ensure accurate assessment of the fetal heart. The following outlines the procedural steps:

  • Step 1: Patient Preparation - The patient is positioned comfortably, typically lying on her back, to facilitate access to the abdomen or vagina, depending on the ultrasound method chosen.
  • Step 2: Application of Gel - If an abdominal ultrasound is performed, a conductive gel is applied to the abdomen. This gel is essential for enhancing the transmission of ultrasound waves, allowing for clearer imaging.
  • Step 3: Transducer Placement - A transducer probe is then placed on the abdomen and moved across various locations to capture images of the fetal heart. In cases where a transvaginal approach is necessary, a transducer is gently inserted into the vagina to obtain more detailed images of the heart.
  • Step 4: Doppler Technique Utilization - The Doppler technique is employed to evaluate blood flow through the heart chambers and valves. This involves measuring the velocity of blood flow, which is critical for assessing the heart's function and detecting any abnormalities.
  • Step 5: Image Acquisition - The ultrasound machine generates real-time images and spectral displays of the fetal heart, allowing the physician to analyze the structure and function of the heart in detail.
  • Step 6: Interpretation of Results - After the images are obtained, the physician interprets the findings, looking for any signs of structural anomalies or abnormal blood flow patterns that may indicate cardiovascular issues.

3. Post-Procedure

After the fetal Doppler echocardiography procedure, there are several considerations for post-procedure care and follow-up. Patients may be monitored briefly to ensure there are no immediate complications or discomfort following the ultrasound. The physician will review the results of the echocardiography and discuss any findings with the patient, including the need for further testing or monitoring if abnormalities are detected. Depending on the results, additional follow-up studies may be scheduled to continue monitoring the fetal heart health. It is also important for the patient to maintain regular prenatal care appointments to ensure comprehensive monitoring of both maternal and fetal health throughout the pregnancy.

XU Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service
26 Professional component: certain procedures are a combination of a physician or other qualified health care professional component and a technical component. when the physician or other qualified health care professional component is reported separately, the service may be identified by adding modifier 26 to the usual procedure number.
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
TC Technical component; under certain circumstances, a charge may be made for the technical component alone; under those circumstances the technical component charge is identified by adding modifier 'tc' to the usual procedure number; technical component charges are institutional charges and not billed separately by physicians; however, portable x-ray suppliers only bill for technical component and should utilize modifier tc; the charge data from portable x-ray suppliers will then be used to build customary and prevailing profiles
