Official Description

Radical resection of tumor, proximal humerus

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Radical resection of the proximal humerus, as described by CPT® Code 23220, is a surgical procedure primarily indicated for the removal of malignant tumors, although it may also be necessary for benign tumors or those of indeterminate nature. The procedure begins with the creation of a skin incision directly over the tumor located in the proximal humerus, or alternatively, a skin flap may be elevated to provide access. The surgeon meticulously dissects the overlying tissue to expose the tumor, ensuring that all affected bone and cartilage in the proximal humerus are resected. This comprehensive approach involves the removal of the tumor en bloc, which means the tumor is excised along with a wide margin of healthy surrounding tissue to ensure complete removal of cancerous cells. The radical resection encompasses not only the bone but also all involved soft tissues, which may include muscles, tendons, fat, blood vessels, lymph vessels, nerves, and any tissues surrounding the joints. To confirm that the surgical margins are free of tumor cells, a separately reportable frozen section may be performed during the procedure. If any margins are found to contain malignancy, additional tissue will be excised until all margins are confirmed to be clear of tumor cells. Post-surgery, drains may be placed as necessary to manage fluid accumulation, and the surgical wound can be closed in layers, or additional reconstructive procedures may be performed if required.

1. Indications

Radical resection of the proximal humerus is indicated for the following conditions:

  • Malignant Neoplasm The primary indication for this procedure is the presence of a malignant tumor in the proximal humerus, necessitating complete removal to prevent further spread of cancer.
  • Benign Tumors In some cases, benign tumors that pose a risk of complications or have the potential for malignant transformation may also require radical resection.
  • Indeterminate Tumors Tumors of indeterminate nature, where the potential for malignancy is uncertain, may warrant radical resection to ensure comprehensive treatment and diagnosis.

2. Procedure

The procedure for radical resection of the proximal humerus involves several critical steps:

  • Step 1: Incision A skin incision is made directly over the tumor located in the proximal humerus. 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 to ensure that the tumor is adequately visualized and that surrounding tissues are preserved as much as possible.
  • Step 3: Resection of Tumor All bone and cartilage in the proximal humerus that is involved with the tumor is resected. The tumor is removed en bloc, which means it is excised along with a wide margin of surrounding healthy tissue to ensure complete removal of any cancerous cells.
  • Step 4: 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 any tissues surrounding the joints, ensuring that no malignant cells remain.
  • Step 5: Frozen Section A separately reportable frozen section may be performed during the procedure to assess the surgical margins for the presence of tumor cells. This step is critical for determining whether additional tissue needs to be removed.
  • Step 6: Additional Resection If the frozen section indicates that margins are not free of tumor cells, additional tissue will be excised until all margins are confirmed to be clear of malignancy.
  • Step 7: Drain Placement Drains may be placed as needed to manage any fluid accumulation post-surgery, which helps in preventing complications such as seromas or hematomas.
  • Step 8: Wound Closure The surgical wound may be closed in layers, ensuring proper healing, or separately reportable reconstructive procedures may be performed if necessary to restore function or appearance.

3. Post-Procedure

After the radical resection of the proximal humerus, patients may require specific post-procedure care to facilitate recovery. This includes monitoring for any signs of infection or complications related to the surgical site. The placement of drains will be managed to ensure proper drainage and minimize fluid accumulation. Patients may also need physical therapy to regain strength and mobility in the affected arm, depending on the extent of the resection and any additional reconstructive procedures performed. Follow-up appointments will be necessary to assess healing and to conduct any further evaluations, including imaging studies, to ensure that all cancerous tissues have been adequately removed.

This is a primary code that can be used with these additional add-on codes.

20932 Add-on Code MPFS Status: Active Code APC N ASC N1 Allograft, includes templating, cutting, placement and internal fixation, when performed; osteoarticular, including articular surface and contiguous bone (List separately in addition to code for primary procedure)
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.
51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
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.
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
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.
78 Unplanned return to the operating/procedure room by the same physician or other qualified health care professional following initial procedure for a related procedure during the postoperative period: it may be necessary to indicate that another procedure was performed during the postoperative period of the initial procedure (unplanned procedure following initial procedure). when this procedure is related to the first, and requires the use of an operating/procedure room, it may be reported by adding modifier 78 to the related procedure. (for repeat procedures, see modifier 76.)
79 Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79. (for repeat procedures on the same day, see modifier 76.)
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
82 Assistant surgeon (when qualified resident surgeon not available): the unavailability of a qualified resident surgeon is a prerequisite for use of modifier 82 appended to the usual procedure code number(s).
