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.

49083 billing questions

When should 49083 be selected instead of 49082?

Use 49083 when imaging is used to guide the paracentesis. Use 49082 when the paracentesis is performed without imaging guidance.

Can the imaging guidance be reported separately?

Imaging guidance is part of 49083. Do not separately report a guidance service for the same needle placement.

Can modifier 50 be appended for fluid removed from both sides?

No. The CMS bilateral adjustment does not apply, and modifier 50 is inappropriate for this service.

What documentation supports 49083?

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.

Can an assistant or co-surgeon be billed for this procedure?

Medicare does not pay an assistant at surgery for 49083. 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.
