What 47533 covers

An interventional radiologist typically places this catheter through the skin and liver into the biliary system, using imaging to guide access and catheter positioning. The external catheter directs bile out of the body into a collection bag, commonly to relieve obstruction from a stricture, stone, or tumor when external drainage is needed. Diagnostic cholangiography and imaging guidance are included when performed, along with the associated radiological supervision and interpretation.

Report 47533 for initial placement of an external drain; use 47534 when the catheter provides internal-external drainage. The record should support the access, catheter placement, drainage approach, and clinical need. The 0-day global includes same-day preoperative and postoperative care. In a same-session multiple-procedure claim, the highest-valued procedure is paid in full and other procedures at 50%. 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.

47533 billing questions

How does 47533 differ from 47534?

47533 describes an external drainage catheter that directs bile outside the body. Use 47534 for a catheter that drains both externally and internally.

Can diagnostic cholangiography be billed separately with 47533?

Diagnostic cholangiography performed as part of the catheter placement is included in 47533. The code also includes imaging guidance and associated radiological supervision and interpretation.

Is modifier 50 appropriate for bilateral biliary drainage?

No. The descriptor and anatomy make bilateral adjustment inappropriate for 47533.

Can an assistant surgeon or co-surgeon be reported?

Medicare does not pay an assistant at surgery for 47533. Co-surgeons and team surgery are not permitted.

How is 47533 affected when other procedures are 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%.

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.
