What 49082 covers

49082 represents needle or catheter entry through the abdominal wall into the peritoneal cavity to withdraw ascitic fluid without imaging guidance. The procedure may be diagnostic, such as sampling new or worsening ascites for evaluation, or therapeutic to relieve symptomatic fluid accumulation, including ascites associated with cirrhosis or malignancy. Physicians commonly perform it at the bedside or in hospital and clinic settings.

Choose 49082 when the tap is performed without imaging guidance; when imaging guides the procedure, report 49083 instead. Documentation should identify the indication, technique, fluid obtained, amount removed, and whether a specimen was sent for testing. Separately performed laboratory analysis is reported under the applicable lab codes. The 0-day global period includes same-day preoperative and postoperative care. When multiple procedures are performed in one session, CMS pays the highest-valued procedure in full and the others at 50%. 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.

49082 billing questions

When should I report 49083 instead?

Report 49083 when imaging guidance is used for the paracentesis. Use 49082 when the procedure is performed without imaging guidance.

Can the ascitic-fluid tests be billed separately?

Yes. Separately performed laboratory testing, such as a fluid cell count or albumin measurement, may be reported under the applicable laboratory codes.

Is modifier 50 appropriate for bilateral paracentesis?

No. CMS identifies bilateral adjustment as inappropriate for this code.

How many units should be reported when a large volume is removed?

Report the procedure, not a unit for each volume removed. Document the amount drained, but do not use the volume as the unit count.

Does the code include same-day care?

Yes. The 0-day global period includes same-day preoperative and postoperative care.

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.
