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

What 47532 covers

A physician injects contrast through an established route into the biliary system and obtains cholangiographic images. The route may be an existing biliary catheter or other established access. Interventional radiologists commonly perform this service in a hospital or outpatient procedural setting to assess duct anatomy, drainage, or a suspected obstruction. Fluoroscopy, when used, is part of the service.

Choose this code when imaging is performed through existing access, rather than by establishing new percutaneous access. The record should identify the access route, document the contrast injection and imaging, and include the clinical reason and findings. Same-day preoperative and postoperative care is included in the 0-day global service. When multiple procedures occur in one session, Medicare pays the highest-valued procedure in full and reduces the others to 50%. The biliary anatomy is not treated as a paired bilateral service, so modifier 50 is not appropriate. Medicare does not pay an assistant at surgery for this service, and does not permit co-surgeon or team-surgery payment.
