Official Description

Excision of chest wall tumor including rib(s)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 21601 involves the excision of a tumor located in the chest wall, which is the structural framework 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 tumors can be categorized further into primary tumors, which originate from the chest wall itself, and secondary tumors, which arise from other locations in the body and subsequently spread to the chest wall. During the excision procedure coded as 21601, the surgeon makes an incision through the skin over the tumor and opens the chest cavity. The operation involves the complete removal of the tumor along with the full thickness of the chest wall, including the adjacent pleura, and a margin of healthy tissue measuring approximately 4-5 centimeters. Additionally, the procedure necessitates the resection of the involved rib as well as at least one rib above and below the tumor site. It is important to note that this specific procedure does not include any reconstruction of the chest wall following the excision, distinguishing it from related procedures that may involve reconstruction efforts.

1. Indications

The excision of a chest wall tumor, as described by CPT® Code 21601, is indicated for various conditions related to the presence of tumors in the chest wall. These indications include:

  • Benign Tumors - Tumors that are non-cancerous and may require removal due to size or location, even though they do not invade surrounding tissues.
  • Malignant Tumors - Cancerous tumors that can invade adjacent tissues or metastasize to other organs, necessitating surgical intervention.
  • Primary Tumors - Tumors that originate from the structures of the chest wall itself.
  • Secondary Tumors - Tumors that have spread to the chest wall from other parts of the body.

2. Procedure

The procedure for excising a chest wall tumor involves several critical steps, which are detailed as follows:

  • Step 1: Incision - The surgeon begins by making an incision through the skin directly over the tumor site. This incision allows access to the underlying structures of the chest wall.
  • Step 2: Opening the Chest - Following the skin incision, the chest cavity is opened to provide the necessary visibility and access to the tumor and surrounding tissues.
  • Step 3: Tumor and Tissue Resection - The full thickness of the chest wall, including the adjacent pleura, is resected. This step is crucial to ensure complete removal of the tumor along with a margin of healthy tissue, typically measuring 4-5 centimeters, to minimize the risk of residual disease.
  • Step 4: Rib Resection - The involved rib, as well as at least one rib above and one rib below the level of the tumor, is excised. This is necessary to ensure that all potentially affected areas are removed.
  • Step 5: Closure - After the tumor and surrounding tissues have been excised, the chest wall is left without reconstruction, concluding the procedure.

3. Post-Procedure

Post-procedure care following the excision of a chest wall tumor typically involves monitoring for complications such as infection or bleeding. Patients may require pain management and respiratory support to aid in recovery. The expected recovery period can vary based on the extent of the surgery and the patient's overall health. Follow-up appointments are essential to assess healing and to monitor for any signs of recurrence of the tumor. Additionally, patients may need to engage in rehabilitation to restore normal function and mobility following the surgical intervention.

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

32674 Add-on Code MPFS Status: Active Code APC C Thoracoscopy, surgical; with mediastinal and regional lymphadenectomy (List separately in addition to code for primary procedure)
38746 Addon Code MPFS Status: Active Code APC C Physician Quality Reporting CPT Assistant Article Thoracic lymphadenectomy by thoracotomy, mediastinal and regional lymphadenectomy (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).
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.)
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).
