About 27645: Radical tibial tumor resection
Reports a major operation removing a tibial tumor through radical oncologic resection, typically when the operative plan requires removal of tumor-bearing bone.
This code describes an extensive operation to remove a tumor involving the tibia, generally by taking out the tumor-bearing bone as part of an oncologic resection. Orthopedic oncologists typically perform it in a hospital operating room after imaging and biopsy have informed surgical planning. The removed tissue is submitted for pathologic examination. The approach and amount of bone removed depend on the tumor and the planned resection; the diagnosis alone does not determine code selection.
Select this code when the operative report supports radical tumor resection of the tibia, rather than limited curettage, lesion excision, or partial bone removal. Documentation should identify the tibial site, tumor, resection performed, and relevant specimen. Medicare assigns a 90-day global period, including the day-before preoperative visit and related postoperative care. 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 paid at 150% for a bilateral procedure. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

27645 billing questions
How is this different from tibial bone-lesion curettage?
Use this code when the operative work is radical oncologic resection of a tibial tumor. A more limited curettage or excision of a bone lesion is represented by a different procedure code.
How does this differ from partial tibial excision?
Code 27640 describes partial removal of the tibia. This code is for radical resection of a tibial tumor, so the operative technique and purpose—not simply the amount of bone removed—guide selection.
What documentation supports reporting this code?
The operative report should identify the tibial tumor and site, describe the radical resection performed, and document the tissue removed. A tumor diagnosis by itself does not establish that the operation was a radical resection.
How are multiple procedures in the same session paid?
The highest-valued procedure is paid in full, and other procedures in the same session are subject to the standard multiple-procedure reduction, with payment at 50%.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be available. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
