What 49423 covers

This service exchanges an existing percutaneous catheter used to drain a fluid collection, such as an abscess, hematoma, seroma, or cyst. An interventional radiologist typically removes the existing catheter and places a replacement through the established access, using fluoroscopy and contrast injection to assess the catheter and collection. The procedure is commonly performed in a hospital radiology suite or another setting equipped for image-guided intervention.

Report the exchange when a catheter is already in place and is replaced, rather than when a new drainage catheter is initially placed. The record should identify the collection and existing catheter, explain the reason for exchange, and document the replacement and imaging. Contrast injection and fluoroscopic guidance with radiological supervision and interpretation are included. The 0-day global period includes same-day preoperative and postoperative care. When multiple procedures occur in one session, the highest-valued procedure is paid in full and the others at 50%. Modifier 50 is inappropriate. Assistant-at-surgery payment requires documented medical necessity; 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.

49423 billing questions

When should this code be chosen instead of 49405, 49406, or 49407?

Use 49423 for exchanging a catheter already draining a collection. Codes 49405, 49406, and 49407 describe image-guided placement of a drainage catheter, with the applicable code determined by the collection site.

Is the fluoroscopic contrast assessment separately reported?

Fluoroscopic guidance, contrast injection, and radiological supervision and interpretation are included in the exchange service.

Can modifier 50 be used for an exchange on both sides?

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

How does Medicare handle this service when other procedures occur in the same session?

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

What documentation supports reporting the exchange?

Document the collection and existing catheter, the reason it needed replacement, the catheter exchange performed, and the fluoroscopic and contrast assessment.

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.
