CPT code 47540: Biliary stent, percutaneous placement2026 Medicare rate & RVUs

Medicare pays $3,956.67 for 47540 nationally in the office and $376.43 in a hospital or facility. Local office rates run $3,429.19–$5,578.88.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 47540 covers

An interventional radiologist or other physician with appropriate procedural training places a stent in the bile ducts through percutaneous access, commonly using imaging to guide the device across an obstructed or narrowed segment. The procedure is generally performed in a hospital or another setting equipped for image-guided biliary intervention. Diagnostic cholangiography may be performed as part of the stent procedure.

Select this code when the documented service meets its specific percutaneous stent-placement circumstances; distinguish it from biliary drainage catheter placement, exchange, or duct dilation. The record should identify the biliary access, target duct or obstruction, stent placement, and imaging performed. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures occur 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. CMS does not pay an assistant at surgery, and co-surgeon and team-surgery billing are not permitted.
