Axillary lymphadenectomy; superficial

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

An axillary lymphadenectomy is a surgical procedure that involves the removal of lymph nodes located in the axilla, or armpit area. This procedure is typically performed to assess or treat conditions such as cancer, particularly breast cancer, where lymph nodes may be affected by malignant cells. The axillary lymph nodes are categorized into three levels based on their anatomical location relative to the pectoralis minor muscle: level I nodes are situated below the lower edge of the pectoralis minor, level II nodes are located beneath the muscle, and level III nodes are found above the muscle. During the procedure, an incision is made in the lowest part of the axilla to access these nodes. The surgeon carefully identifies the borders of the pectoralis major and latissimus dorsi muscles, as well as the axillary vein, which is dissected from surrounding tissues to minimize damage to nearby structures. The neural structures in the axilla are also identified and protected throughout the procedure. The surgeon excises the axillary lymph nodes along with the surrounding fat pad, typically removing between 15 to 25 nodes from the area beneath the axillary vein and adjacent to the nerves and muscles. After the excision of any cancerous or suspicious tissue, a drain is placed to prevent fluid accumulation, and the surgical wound is subsequently closed. For coding purposes, the CPT® Code 38740 is used for the excision of superficial lymph nodes, specifically those in level I, while the CPT® Code 38745 is designated for the complete removal of axillary lymph nodes encompassing levels I through III.

1. Indications

The axillary lymphadenectomy procedure is indicated for various clinical scenarios, particularly in the context of cancer management. The following conditions may warrant this surgical intervention:

  • Breast Cancer: The primary indication for an axillary lymphadenectomy is the presence of breast cancer, where lymph nodes may be involved with metastatic disease.
  • Suspicious Lymph Nodes: The procedure is also indicated when imaging studies or physical examinations reveal suspicious lymph nodes that require further evaluation or removal.
  • Staging of Cancer: Axillary lymphadenectomy is performed to help stage the cancer, determining the extent of disease spread and guiding further treatment options.

2. Procedure

The axillary lymphadenectomy procedure involves several critical steps to ensure the effective removal of lymph nodes while preserving surrounding structures. The following procedural steps are undertaken:

  • Step 1: Incision An incision is made in the lowest area of the axilla to provide access to the axillary lymph nodes. This incision is strategically placed to minimize scarring and facilitate optimal exposure of the surgical field.
  • Step 2: Identification of Anatomical Structures The surgeon identifies the borders of the pectoralis major and latissimus dorsi muscles, which serve as important landmarks during the procedure. This identification is crucial for navigating the surgical area and avoiding damage to vital structures.
  • Step 3: Dissection of the Axillary Vein The axillary vein is carefully dissected from the surrounding tissue. This step is essential to access the lymph nodes while ensuring that the vein remains intact and functional.
  • Step 4: Protection of Neural Structures The axillary neural structures are identified and protected throughout the procedure. This is vital to prevent nerve damage, which could lead to complications such as loss of sensation or motor function in the arm.
  • Step 5: Excision of Lymph Nodes The axillary lymph nodes, along with the surrounding fat pad, are excised. Typically, 15 to 25 nodes are removed from beneath the axillary vein and along the nerves and muscles of the axilla. This excision is performed to ensure that any cancerous or suspicious tissue is completely removed.
  • Step 6: Drain Placement and Wound Closure After the excision, a drain is placed to prevent fluid accumulation in the surgical site. Finally, the surgical wound is closed, ensuring proper healing and minimizing the risk of infection.

3. Post-Procedure

Post-procedure care following an axillary lymphadenectomy is essential for optimal recovery. Patients are typically monitored for any signs of complications, such as infection or excessive bleeding. The drain placed during surgery is usually removed after a few days, depending on the amount of fluid collected. Patients may experience discomfort, swelling, or limited range of motion in the shoulder and arm on the affected side, which can be managed with pain relief medications and physical therapy. Follow-up appointments are necessary to assess healing and to discuss any further treatment options, especially if the lymph nodes were found to be cancerous. It is important for patients to adhere to post-operative instructions provided by their healthcare team to ensure a smooth recovery process.

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.
AS Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery
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.
50 Bilateral procedure: unless otherwise identified in the listings, bilateral procedures that are performed at the same session, should be identified by adding modifier 50 to the appropriate 5 digit code. note: this modifier should not be appended to designated "add-on" codes (see appendix d).
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.
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.
