Interventional radiology

About 47535: External-to-internal biliary catheter conversion

Reports percutaneous conversion of an existing external biliary drainage catheter to an internal-external catheter, including cholangiography and imaging guidance.

An interventional radiologist converts an existing external biliary drainage catheter by directing the catheter across the biliary obstruction and into the bowel, creating internal-external drainage. The service is typically performed in a hospital imaging suite for a patient whose biliary obstruction was initially managed with external drainage and can now be traversed. Diagnostic cholangiography, imaging guidance, and the associated radiological supervision and interpretation are included in the conversion service.

Report this code when the existing external catheter is converted, rather than when a catheter is newly placed or an existing catheter is simply exchanged. The procedure note should identify the prior external catheter, document the conversion and final catheter position, and support the cholangiographic and imaging work. The service has a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures 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.

47535 billing questions

How is conversion different from initial internal-external catheter placement?

Use 47535 when an existing external biliary drainage catheter is converted to internal-external drainage. Initial placement of an internal-external catheter is reported with 47534.

How is conversion different from catheter exchange?

Code 47535 describes changing an existing external catheter into an internal-external drainage catheter. Code 47536 describes exchange of an existing biliary drainage catheter, not this conversion.

Can cholangiography or imaging guidance be billed separately?

Diagnostic cholangiography, imaging guidance, and associated radiological supervision and interpretation are included in 47535.

Should modifier 50 be appended?

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

What documentation supports reporting 47535?

Document the existing external catheter, the percutaneous conversion, cholangiographic findings, and the final internal-external catheter position.

How are other same-session procedures handled?

The highest-valued procedure is paid in full, and other procedures in the same session are subject to the standard multiple-procedure reduction. Assistant-at-surgery payment is restricted; co-surgeons and team surgery are not permitted.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
