What 59001 covers
An obstetrician or maternal-fetal medicine specialist uses a needle to remove excess amniotic fluid from the amniotic cavity. The procedure is commonly performed with ultrasound guidance in a hospital or other procedural setting for symptomatic polyhydramnios. Its purpose is fluid reduction, not collection of a sample for prenatal diagnosis.
Choose this code when the documented service is therapeutic fluid removal. The record should support the indication, the amniotic cavity as the treatment site, and the procedure performed. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple-procedure reduction. Modifier 50 is inappropriate. CMS does not pay an assistant at surgery; 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.

59001 billing questions
How does this differ from 59000?
Use 59001 for therapeutic removal of excess amniotic fluid. Code 59000 is for diagnostic amniocentesis, where fluid is sampled for testing.
What should the record support?
Document the therapeutic indication, that fluid was removed from the amniotic cavity, and the procedure performed. The note should make clear that the service was fluid reduction rather than diagnostic sampling.
Is modifier 50 appropriate?
No. CMS identifies bilateral adjustment as inappropriate for this code.
How does the 0-day global period affect same-day care?
Same-day preoperative and postoperative care is included in the procedure's payment.
What happens when another procedure is performed in the same session?
Under the standard multiple-procedure rule, the highest-valued procedure is paid in full and other procedures are reduced. CMS does not pay an assistant at surgery, and co-surgeons and team surgery are not permitted.
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.
