About 49406: Image-guided peritoneal fluid drainage
Report percutaneous, image-guided catheter placement to drain a fluid collection in the peritoneal or retroperitoneal space.
This service places a catheter through the skin into a fluid collection in the peritoneal or retroperitoneal space so the collection can be drained. Typical cases include image-guided drainage of an abdominal abscess, hematoma, or cyst. An interventional radiologist commonly performs the procedure in a hospital imaging suite or other procedural setting, using imaging to guide access and catheter position.
Select this code when the collection is peritoneal or retroperitoneal; collections in a visceral organ or another specified access route belong to different codes. The report should identify the collection’s location and nature, the imaging guidance and access used, and catheter placement and drainage. This is a minor procedure with a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures are performed in one session, the highest-valued is paid in full and the others are subject to the standard 50% reduction. Modifier 50 is inappropriate; assistant-at-surgery payment is restricted, and co-surgeons and team surgery are not permitted.

49406 billing questions
How does this differ from 49405?
Use 49406 for a peritoneal or retroperitoneal collection. Code 49405 is for a collection in a visceral site, such as an organ.
When is 49407 more appropriate?
Code 49407 is for catheter drainage reached through a transvaginal or transrectal route. Code 49406 covers percutaneous drainage of a peritoneal or retroperitoneal collection.
Can the imaging guidance be billed separately?
Image guidance is part of this catheter-drainage service. The procedure documentation should identify the guidance used and how it directed access and catheter placement.
Can modifier 50 be used for collections on both sides?
No. CMS identifies bilateral adjustment as inappropriate for this code, so modifier 50 should not be used.
How does the multiple-procedure rule affect another procedure in the same session?
The highest-valued procedure is paid in full, and the other procedure or procedures are subject to the standard 50% reduction.
Is an assistant or co-surgeon payable for this procedure?
Assistant-at-surgery payment is restricted. Co-surgeons and team surgery are not permitted under the CMS rules provided for this code.
