Resection of mediastinal tumor

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 39220 involves the surgical resection of a mediastinal tumor. The mediastinum is the central compartment of the thoracic cavity, situated between the lungs, and contains vital structures such as the heart, trachea, esophagus, and major blood vessels. The term 'resection' refers to the surgical removal of tissue, in this case, a tumor or cyst located within the mediastinal space. The approach taken by the physician during this procedure is determined by the specific location of the mass within the mediastinum. For tumors located anteriorly, a median sternotomy is commonly performed, which involves making an incision along the sternum to access the chest cavity. Conversely, for posterior lesions, a posterolateral approach is utilized, allowing access from the side of the chest. During the procedure, the surgeon carefully dissects through the surrounding tissues to reach the mediastinal space, where the tumor or cyst is identified and exposed. If the lesion is a cyst, the goal is to remove it completely, including the cyst wall, to minimize the risk of recurrence. However, if the cyst wall is firmly attached to critical structures such as the tracheobronchial tree or esophagus, the surgeon may opt to remove only the mucosal lining of the affected area. In cases involving a mediastinal tumor, the objective is to excise the tumor entirely whenever feasible. After the successful removal of the cyst or tumor, the surgical incisions are meticulously closed in layers to promote optimal healing.

1. Indications

The procedure for resection of a mediastinal tumor is indicated for various conditions that may present in the mediastinal area. These include:

  • Mediastinal Tumor A neoplasm located within the mediastinum that may require surgical intervention for removal.
  • Mediastinal Cyst A fluid-filled sac in the mediastinal space that may cause symptoms or complications, necessitating resection.

2. Procedure

The surgical procedure for the resection of a mediastinal tumor involves several critical steps, which are outlined as follows:

  • Step 1: Patient Positioning and Anesthesia The patient is positioned appropriately, typically in a supine position, and general anesthesia is administered to ensure comfort and immobility during the procedure.
  • Step 2: Incision Depending on the location of the mediastinal mass, the surgeon makes an incision. A median sternotomy is performed for anterior lesions, while a posterolateral thoracotomy is utilized for posterior lesions, allowing access to the mediastinal space.
  • Step 3: Dissection The surgeon carefully dissects through the layers of tissue to reach the mediastinum. This involves meticulous handling of surrounding structures to minimize trauma and preserve function.
  • Step 4: Identification and Exposure of the Lesion Once the mediastinal space is accessed, the cyst or tumor is located and exposed. This step is crucial for determining the extent of the lesion and planning the resection.
  • Step 5: Resection of the Lesion If the lesion is a cyst, it is resected along with the entire cyst wall when possible to prevent recurrence. If the cyst wall is adherent to critical structures, the surgeon may remove only the mucosal lining of the affected area. In the case of a tumor, the goal is to excise the tumor in its entirety, ensuring clear margins when feasible.
  • Step 6: Closure After the cyst or tumor has been successfully removed, the surgical incisions are closed in layers. This layered closure technique is essential for promoting proper healing and reducing the risk of complications.

3. Post-Procedure

Post-procedure care following the resection of a mediastinal tumor includes monitoring the patient for any signs of complications, such as bleeding or infection. Patients may require pain management and respiratory support as they recover from anesthesia. Follow-up imaging may be necessary to ensure that the tumor or cyst has been completely removed and to monitor for any recurrence. The healthcare team will provide specific instructions regarding activity restrictions and wound care to facilitate optimal recovery.

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).
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.
76 Repeat procedure or service by same physician or other qualified health care professional: it may be necessary to indicate that a procedure or service was repeated by the same physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 76 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
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).
