About 47146: Donor liver venous reconstruction
A transplant surgeon reports donor-liver backbench reconstruction for each venous connection created to establish graft outflow before liver implantation.
A transplant surgeon reconstructs venous outflow on a donor liver graft on the back table before implantation. The work may involve joining or shaping graft veins to create a usable outflow pathway. It is distinct from removing the donor liver and implanting the graft in the recipient. This work is performed in the operating room during preparation of a graft from a deceased or living donor.
Report one unit for each venous anastomosis performed. The operative report should identify the graft, the veins joined, the number of reconstructions, and the work performed. When other procedures occur during the same session, CMS applies the standard multiple-procedure reduction: the highest-valued procedure is paid in full, and the other procedures are paid at 50%.

47146 billing questions
How does this differ from whole-graft preparation?
Code 47143 describes backbench preparation of a whole donor liver. Code 47146 identifies venous reconstruction work, so the record should show that this work was performed.
How many units should be reported?
Report one unit for each venous anastomosis performed. Document the number of reconstructed venous connections in the operative report.
Can this be reported with liver transplantation?
The backbench reconstruction occurs before implantation, while 47135 describes transplantation in the recipient. The operative record should support each service performed.
What documentation supports reporting this code?
Document the donor graft, the veins reconstructed, the anastomosis work, and the number of connections. A general statement that the graft was prepared does not identify the venous reconstruction.
How does the multiple-procedure payment rule affect this service?
When other procedures are performed in the same session, CMS pays the highest-valued procedure in full and pays the other procedures at 50%.
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.
