Official Description

Excision of chest wall tumor involving rib(s), with plastic reconstruction; without mediastinal lymphadenectomy

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 21602 involves the excision of a tumor located in the chest wall, which is the structure composed of bones and muscles that encase the chest cavity, safeguarding vital organs such as the lungs, heart, and major blood vessels. Tumors in this area can be classified as benign or malignant, with benign tumors typically not invading surrounding tissues or spreading to other parts of the body, although they may require removal due to their size or location. In contrast, malignant tumors have the potential to invade adjacent tissues or metastasize to distant organs. The distinction between primary and secondary tumors is also important; primary tumors originate within the chest wall itself, while secondary tumors arise from other locations in the body and subsequently spread to the chest wall. In the context of CPT® Code 21602, the procedure entails not only the excision of the tumor but also the reconstruction of the chest wall following the removal. This reconstruction is crucial for restoring the structural integrity of the chest wall after the tumor and affected ribs have been excised. The specific approach to reconstruction may vary based on the size and location of the defect created by the tumor removal. Various materials, including alloplastic options like stainless steel and titanium, as well as biological grafts such as ribs or bone grafts, may be utilized to repair the skeletal defects. Additionally, soft tissue defects can be addressed using muscle flaps from the latissimus dorsi, pectoralis major, or abdominus rectus, among other techniques. This comprehensive approach ensures that both the tumor is effectively removed and the chest wall is reconstructed to maintain its function and appearance.

1. Indications

The procedure associated with CPT® Code 21602 is indicated for the excision of tumors located in the chest wall. The specific indications for this procedure include:

  • Chest Wall Tumors: Presence of benign or malignant tumors in the chest wall that require surgical intervention for removal.
  • Size or Location of Tumors: Tumors that, due to their size or location, may pose a risk to surrounding structures or may cause symptoms necessitating excision.
  • Reconstruction Needs: Cases where the excision of the tumor results in a significant defect in the chest wall that requires reconstruction to restore structural integrity.

2. Procedure

The procedure for CPT® Code 21602 involves several critical steps to ensure the effective removal of the tumor and subsequent reconstruction of the chest wall. The steps are as follows:

  • Step 1: Incision and Exposure The surgical process begins with an incision over the tumor site, allowing access to the chest wall. The skin and underlying tissues are carefully incised to expose the tumor and the surrounding structures.
  • Step 2: Tumor Excision Once the tumor is accessible, the surgeon excises the tumor along with a margin of healthy tissue, typically 4-5 cm, to ensure complete removal and minimize the risk of recurrence. The involved rib and at least one rib above and below the tumor site are also resected to ensure thorough excision.
  • Step 3: Chest Wall Reconstruction After the tumor and affected ribs have been removed, the next step is to reconstruct the chest wall. The reconstruction may involve the use of various materials, such as alloplastic materials (e.g., stainless steel, titanium) or biological grafts (e.g., ribs or bone grafts). The choice of material depends on the size and location of the defect created by the excision.
  • Step 4: Soft Tissue Repair In cases where soft tissue defects are present, the surgeon may utilize muscle flaps from the latissimus dorsi, pectoralis major, or abdominus rectus to repair the defect. Other options may include the use of omentum or fasciocutaneous flaps to ensure adequate coverage and support for the reconstructed area.

3. Post-Procedure

Following the procedure, patients typically require monitoring for any complications related to the surgery. Post-operative care may include pain management, wound care, and monitoring for signs of infection. The recovery process will vary depending on the extent of the surgery and the individual patient's health status. Patients may also need follow-up appointments to assess the healing of the surgical site and the effectiveness of the reconstruction. Rehabilitation may be necessary to restore function and strength in the chest wall area, particularly if significant muscle or structural support was involved in the reconstruction.

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).
52 Reduced services: under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. under these circumstances the service provided can be identified by its usual procedure number and the addition of modifier 52, signifying that the service is reduced. this provides a means of reporting reduced services without disturbing the identification of the basic service. note: for hospital outpatient reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well-being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
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.)
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).
