What 49083 covers

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.

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.

49083 billing questions

When should 49083 be selected instead of 49082?

Document the clinical reason for drainage, that peritoneal fluid was removed, and that imaging was used to guide the procedure.

How is 49083 affected when another procedure is performed in the same session?

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