About 49083: Image-Guided Abdominal Paracentesis

Report image-guided abdominal paracentesis when a clinician removes peritoneal fluid for diagnosis or symptom relief using imaging to guide needle placement.

A clinician uses imaging, commonly ultrasound, to guide a needle or catheter into the peritoneal cavity and remove ascitic fluid. The procedure may obtain fluid for diagnostic testing or relieve symptoms from fluid accumulation, such as abdominal distention or discomfort. It is performed in settings including hospitals, outpatient departments, and offices by physicians or other qualified practitioners who perform paracentesis.

Select 49083 when imaging guidance is used; 49082 is the corresponding code for paracentesis without imaging guidance. Documentation should support the indication, fluid removal, and use of imaging to guide the procedure. The 0-day global period includes same-day preoperative and postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and others are subject to the standard 50% reduction. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery, and co-surgeons and team surgery are not permitted.
