About 59000: Diagnostic amniotic fluid aspiration
Percutaneous amniotic fluid collection for prenatal diagnostic testing, such as evaluation of fetal chromosomes, genetic conditions, or infection.
An obstetrician or maternal-fetal medicine specialist uses a needle passed through the maternal abdomen and uterine wall to collect amniotic fluid. Ultrasound commonly helps locate the fluid pocket and avoid the fetus and placenta. The sample is sent for diagnostic laboratory testing, such as chromosome or genetic analysis or evaluation for fetal infection. The procedure is performed in an office or facility setting where prenatal diagnostic sampling is provided.
Report 59000 for diagnostic fluid collection, not for fluid removal intended to treat a condition. The record should identify the diagnostic indication, the sampling procedure, and the specimen obtained; laboratory analysis is separately represented. This minor procedure has 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 the others are subject to the standard 50% reduction. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this service; co-surgeons and team surgery are not permitted.

59000 billing questions
How does 59000 differ from therapeutic amniocentesis?
Use 59000 when fluid is collected for diagnosis. Code 59001 describes amniotic fluid removal for a therapeutic purpose.
Is ultrasound guidance included in 59000?
Ultrasound is commonly used to guide needle placement. When guidance is performed and documented, 76946 may be reported separately, subject to applicable coding edits.
Can modifier 50 be used for sampling from both sides?
No. The CMS bilateral adjustment does not apply, and modifier 50 is inappropriate for this service.
Can an assistant or co-surgeon be reported?
Medicare does not pay an assistant at surgery for 59000. Co-surgeons and team surgery are not permitted.
What documentation supports reporting 59000?
Document the diagnostic reason for sampling, the amniocentesis performed, and the fluid specimen obtained. Keep the diagnostic purpose distinct from therapeutic fluid removal.
