About 28171: Tarsal bone tumor resection
Resection of a tumor involving a tarsal bone, reported when the operative service removes the tumor and affected bone rather than performing limited curettage.
This operation removes a tumor involving a tarsal bone, such as the talus, calcaneus, or another bone of the midfoot or hindfoot. An orthopedic foot-and-ankle surgeon or podiatric surgeon typically performs it in an operating room, exposing the involved bone and resecting the tumor and the extent of bone required by the operative plan. The specimen may be submitted for pathologic examination.
Select this code when the documented service is a tarsal bone tumor resection, rather than limited curettage or excision of a benign lesion. The operative report should identify the tarsal bone and describe the tumor and extent of resection. Medicare includes the day-before preoperative visit and 90 days of related postoperative care in the major-surgery global period. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple-procedure reduction. Modifier 50 is inappropriate for this code. An assistant at surgery may be paid; co-surgeons and team surgery are not permitted.

28171 billing questions
How is this different from a tarsal bone curettage code?
Use 28171 for resection of a tumor involving a tarsal bone. A limited curettage or excision of a benign lesion may fit a different code, depending on the bone and work documented.
What documentation supports reporting 28171?
The operative report should identify the tarsal bone, the tumor, and the extent of the bone resection. Pathology results may support the diagnosis but do not replace documentation of the operation performed.
Can modifier 50 be used when both feet are treated?
Modifier 50 is inappropriate for this code. The CMS descriptor and anatomy do not support a bilateral adjustment.
How are other procedures in the same session paid?
The highest-valued procedure is paid in full, and other procedures are subject to the standard multiple-procedure reduction when performed in the same session.
Is an assistant surgeon payable?
CMS permits payment for an assistant at surgery. Co-surgeons and team surgery are not permitted for this code.
What postoperative care is included?
The major-surgery global period includes the day-before preoperative visit and 90 days of related postoperative care.
Where these rates come from
