What 59015 covers
A clinician obtains a small sample of chorionic villi from the placenta for prenatal diagnostic testing. Sampling may use a transcervical catheter or a transabdominal needle, with ultrasound used to guide the approach. Maternal-fetal medicine specialists and obstetricians commonly perform the procedure in an outpatient setting when testing for a fetal chromosomal or genetic condition is indicated.
Report 59015 for the sampling procedure, documenting the indication, approach, and specimen obtained. The genetic analysis is a separate laboratory service when performed and reported. Medicare assigns a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to a 50% reduction. Modifier 50 is inappropriate for this sampling. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.
