About 47425: Open common bile duct stone removal
Reports open incision of the common bile duct to extract a calculus when operative treatment requires direct access to the duct.
Code 47425 represents open choledochotomy to remove a calculus from the common bile duct. The surgeon exposes the extrahepatic duct, incises its wall, and extracts the stone. The procedure is performed by a surgeon in an operating room when open duct surgery is needed for stone removal. It is distinct from an incision of the gallbladder or duct exploration without calculus removal.
Report the code when the operative note supports an incision into the bile duct and extraction of a calculus; documentation should identify the duct and describe the removal. Do not separately report overlapping duct work when a combined cholecystectomy and common-duct procedure describes the operation performed. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. In same-session multiple procedures, the highest-valued procedure is paid in full and others at 50%. Modifier 50 is inappropriate for this single-duct service. Assistant-at-surgery payment may be made; co-surgeons require supporting documentation, and team-surgery payment is not permitted.

47425 billing questions
How does 47425 differ from 47420?
Use 47425 when the surgeon incises the common bile duct and removes a calculus. Code 47420 describes duct exploration without calculus removal as the defining service.
Can 47425 be reported with a cholecystectomy?
A cholecystectomy may occur during the same operation, but do not separately report duct work that is included in a combined cholecystectomy and common-duct procedure code.
Is modifier 50 appropriate?
No. This is a single bile-duct service, not a bilateral procedure; modifier 50 is inappropriate.
What documentation supports 47425?
The operative report should establish that the surgeon made an incision in the bile duct and removed a calculus. Duct exploration alone does not support this code.
How are assistants and co-surgeons handled?
Assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation, and team-surgery payment is not permitted.
