Ultrasonic guidance for chorionic villus sampling (CVS) involves the use of ultrasound technology to assist in the safe and accurate collection of chorionic villi, which are small, finger-like projections found in the placenta. These villi share the same genetic material as the fetus, making them crucial for genetic testing. The primary purpose of CVS is to detect potential fetal genetic disorders, including conditions such as Tay-Sachs disease, hemophilia, and Down syndrome. Before the CVS procedure is initiated, an ultrasound examination of the pregnant uterus is conducted to assess the fetus's position and to locate the placenta accurately. This preliminary imaging is essential for determining the safest approach for the sampling procedure. CVS can be performed using two methods: transvaginally, where a catheter is inserted through the cervix to reach the placenta, or through the abdominal wall, where a needle is guided into the placenta. Throughout the procedure, continuous ultrasound imaging is employed to ensure the correct placement of the catheter or needle, facilitating the aspiration of the chorionic villus sample. Following the procedure, the physician is responsible for providing a comprehensive written report detailing the imaging aspects of the CVS, which is critical for documentation and further medical evaluation.

Chorionic villus sampling (CVS) is indicated for the following conditions:
The procedure for chorionic villus sampling involves several critical steps to ensure accurate sampling and patient safety:
After the chorionic villus sampling procedure, patients may be monitored for any immediate complications. It is important for the physician to provide post-procedure care instructions, which may include recommendations for activity levels and signs of potential complications to watch for. The physician will also prepare a written report detailing the imaging component of the procedure, which is essential for medical records and further evaluation.

| 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. | XS | Separate structure, a service that is distinct because it was performed on a separate organ/structure |
