What 59074 covers

This procedure drains fluid from a collection within the fetus, rather than removing amniotic fluid from the uterus. Examples include fetal thoracentesis for a pleural effusion and fetal paracentesis for ascites. A maternal-fetal medicine specialist or fetal therapy physician typically performs the intervention in a hospital setting, using ultrasound to guide access and monitor the fetus during drainage. Ultrasound guidance is part of the reported service.

Choose the code when the treatment is drainage of fetal fluid; document the collection’s location, the therapeutic reason, and the procedure performed. Distinguish this from therapeutic amniocentesis, which removes amniotic fluid. The code has a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and the others are subject to the standard multiple procedure reduction. Bilateral adjustment is inappropriate. An assistant at surgery may be paid; co-surgeons and team surgery are not permitted.

59074 billing questions

When should this be reported instead of therapeutic amniocentesis?

Report 59074 for drainage of a fluid collection within the fetus, such as a pleural effusion or ascites. Therapeutic amniocentesis removes excess amniotic fluid from the amniotic cavity.

Is ultrasound guidance separately reported?

No. Ultrasound guidance is included in the fetal fluid drainage service.

What documentation supports reporting 59074?

Document the fetal fluid collection and its location, the clinical reason for drainage, and the drainage procedure performed. For example, identify a pleural effusion when performing fetal thoracentesis.

How are other procedures in the same session paid?

Under the standard multiple procedure reduction, the highest-valued procedure is paid in full and other procedures performed in that session are paid at 50%.

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.
