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.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

59015 billing questions

How is chorionic villus sampling different from diagnostic amniocentesis?

59015 reports sampling placental villi, while 59000 reports sampling amniotic fluid. The appropriate procedure depends on the diagnostic method and specimen obtained.

Can ultrasound guidance be reported with 59015?

CPT 76945 describes ultrasound guidance for chorionic villus sampling. Report it when the guidance service is performed and documented.

Is the genetic laboratory analysis included in 59015?

No. Code 59015 represents obtaining the placental tissue; laboratory analysis is a distinct service when performed and reported.

Should modifier 50 be used for sampling from both sides of the placenta?

No. Modifier 50 is inappropriate for this procedure. Document the sampling performed and the approach used.

What same-session payment rules affect 59015?

Same-day preoperative and postoperative care is included in its 0-day global period. In a session with multiple procedures, the highest-valued procedure is paid in full and other procedures are subject to a 50% reduction.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
