Official Description

Radical resection of tumor, radius or ulna

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Radical resection of a tumor in the radius or ulna, as described by CPT® Code 25170, is a surgical procedure primarily indicated for the removal of malignant neoplasms. However, it may also be necessary for benign tumors or tumors of indeterminate nature. The procedure begins with the creation of a skin incision directly over the tumor site, or alternatively, a skin flap may be elevated to provide access. The surgeon meticulously dissects the overlying tissue to expose the tumor. During the resection, all bone and cartilage in the radius or ulna that is involved with the tumor is excised. This process involves removing the tumor en bloc, which means the tumor is taken out in one piece along with a wide margin of surrounding healthy tissue to ensure complete removal. The radical resection encompasses not only the excision of the tumor but also all affected soft tissues, which may include muscles, tendons, fat, blood vessels, lymph vessels, nerves, and adjacent joint tissues. To confirm that the surgical margins are free of tumor cells, a separately reportable frozen section may be performed. If any margins are found to contain malignancy, additional tissue will be excised until all margins are clear. Post-surgery, drains may be placed as necessary, and the surgical wound can be closed in layers, or additional reconstructive procedures may be performed if required.

1. Indications

Radical resection of a tumor in the radius or ulna is indicated for the following conditions:

  • Malignant Neoplasm The primary indication for this procedure is the presence of a malignant tumor in the radius or ulna, necessitating complete removal to prevent further spread of cancer.
  • Benign Tumors In some cases, benign tumors that pose a risk of complications or have uncertain behavior may also require radical resection.
  • Tumors of Indeterminate Nature Tumors that cannot be definitively classified as benign or malignant may necessitate radical resection to ensure comprehensive treatment and evaluation.

2. Procedure

The procedure for radical resection of a tumor in the radius or ulna involves several critical steps:

  • Step 1: Incision A skin incision is made directly over the tumor site on the radius or ulna. Alternatively, a skin flap may be created and elevated to provide adequate access to the underlying structures.
  • Step 2: Dissection The surgeon carefully dissects the overlying tissue to expose the tumor. This step is crucial for visualizing the tumor and surrounding structures to ensure complete resection.
  • Step 3: Resection of Involved Bone and Cartilage All bone and cartilage in the radius or ulna that shows tumor involvement is resected. This ensures that no cancerous cells remain in the bone structure.
  • Step 4: En Bloc Tumor Removal The tumor is removed en bloc, meaning it is excised in one piece along with a wide margin of surrounding healthy tissue. This technique is essential for minimizing the risk of residual tumor cells.
  • Step 5: Soft Tissue Excision The radical resection includes the excision of all involved soft tissue, which may encompass muscles, tendons, fat, blood vessels, lymph vessels, nerves, and tissues surrounding the joints.
  • Step 6: Frozen Section Analysis A separately reportable frozen section may be performed to assess the surgical margins for tumor cells. If malignancy is detected at the margins, additional tissue is removed until all margins are confirmed to be free of tumor cells.
  • Step 7: Drain Placement Drains may be placed as needed to prevent fluid accumulation at the surgical site, facilitating proper healing.
  • Step 8: Wound Closure The surgical wound may be closed in layers, or if necessary, separately reportable reconstructive procedures may be performed to restore the area.

3. Post-Procedure

After the radical resection procedure, patients can expect specific post-operative care and considerations. The surgical site will be monitored for signs of infection, and the placement of drains will help manage any fluid accumulation. Patients may experience pain and swelling, which can be managed with appropriate analgesics. The recovery process will vary depending on the extent of the resection and any additional reconstructive procedures performed. Follow-up appointments will be necessary to assess healing and to review the results of the frozen section analysis. Rehabilitation may be required to restore function and strength in the affected limb, and patients will be advised on activity restrictions during the recovery period.

20933 Add-on Code MPFS Status: Active Code APC N ASC N1 Allograft, includes templating, cutting, placement and internal fixation, when performed; hemicortical intercalary, partial (ie, hemicylindrical) (List separately in addition to code for primary procedure)

22 Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service.
58 Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78.
62 Two surgeons: when 2 surgeons work together as primary surgeons performing distinct part(s) of a procedure, each surgeon should report his/her distinct operative work by adding modifier 62 to the procedure code and any associated add-on code(s) for that procedure as long as both surgeons continue to work together as primary surgeons. each surgeon should report the co-surgery once using the same procedure code. if additional procedure(s) (including add-on procedure(s) are performed during the same surgical session, separate code(s) may also be reported with modifier 62 added. note: if a co-surgeon acts as an assistant in the performance of additional procedure(s), other than those reported with the modifier 62, during the same surgical session, those services may be reported using separate procedure code(s) with modifier 80 or modifier 82 added, as appropriate.
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
