CPT® Code 28173

Radical resection of a tumor in the metatarsal region is a surgical procedure primarily indicated for the removal of malignant neoplasms, although it may also be necessary for benign tumors or tumors of indeterminate nature. This procedure involves a comprehensive approach to ensure complete excision of the tumor along with a significant margin of healthy tissue to minimize the risk of residual cancerous cells. The process begins with a skin incision made directly over the tumor site, or alternatively, a skin flap may be created and elevated to provide better access. Once the overlying tissue is carefully dissected, the tumor is exposed for removal. The radical resection entails excising not only the tumor itself but also all associated bone and cartilage that show signs of tumor involvement. This extensive removal includes all affected soft tissues, which may encompass muscles, tendons, fat, blood vessels, lymph vessels, nerves, and any tissues surrounding the joints. To ensure that the surgical margins are clear of malignancy, a frozen section analysis is performed during the procedure. If any margins are found to contain tumor cells, further tissue is excised until all margins are confirmed to be free of malignancy. Post-surgery, drains may be placed as necessary to manage fluid accumulation, and the surgical wound is typically closed in layers. In some cases, additional reconstructive procedures may be required and reported separately. For coding purposes, it is important to note that specific codes are designated for different types of bone tumor resections, such as code 28171 for tarsal bones excluding the talus or calcaneus, code 28173 for metatarsal tumors, and code 28175 for phalanx of the toe.
