Chorionic villus sampling is reported with which code?

Chorionic villus sampling (CVS) is a prenatal test where a sample of chorionic villi is taken from the placenta for genetic testing. The procedure is typically performed between the 10th and 13th week of pregnancy. The correct CPT code for this procedure is 59015, which specifically denotes "Chorionic villus sampling, transabdominal."

The choice of this code is significant because it reflects the specificity and technique used during the procedure. This coding captures the nature of the service provided, which is important for proper billing, reimbursement, and tracking of healthcare services related to prenatal diagnosis. The other codes do not represent chorionic villus sampling; they may correspond to different prenatal care services or assessments, making 59015 the accurate choice for CVS.
