What 47534 covers

An interventional radiologist or other qualified physician accesses the biliary tree through the skin and liver, evaluates the ducts with cholangiography, and places a catheter that permits bile to drain internally into the bowel and externally through the catheter. This approach may be used for biliary obstruction when drainage across the obstructed segment is feasible and external access is also needed. The service is commonly performed in a hospital imaging or interventional suite.

Report this code for placement of the internal-external drainage catheter, not for an external-only catheter. The service includes diagnostic cholangiography and imaging guidance with associated radiological supervision and interpretation; document the access route, catheter position and drainage configuration. The procedure has a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures occur in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate for this service. Medicare does not pay an assistant at surgery, and co-surgeons and team surgery are not permitted.

47534 billing questions

How does this differ from 47533?

47534 is for an internal-external catheter, which drains into the bowel and also provides external drainage. 47533 is for an external drainage catheter.

Can the cholangiogram or imaging guidance be billed separately?

Diagnostic cholangiography and imaging guidance associated with catheter placement are included in this service. Do not separately report them as though they were independent services.

Should modifier 50 be appended for bilateral drainage?

No. The biliary drainage service is not reported as a paired-side procedure, and modifier 50 is inappropriate.

How are other procedures in the same session paid?

The highest-valued procedure is paid in full; other procedures in the same session are subject to the standard multiple-procedure reduction.

Can an assistant surgeon or co-surgeon be reported?

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

What documentation supports reporting 47534?

Document the percutaneous access, cholangiographic evaluation, catheter position, and that the catheter provides both internal and external drainage.

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.
