Official Description

Mediastinotomy with exploration, drainage, removal of foreign body, or biopsy; cervical approach

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

A mediastinotomy is a surgical procedure that involves accessing the mediastinum, the central compartment of the thoracic cavity, through a cervical approach. This approach is specifically designed to explore the superior mediastinum, which is the upper part of the mediastinal space located between the lungs. The procedure may involve several key actions, including exploration of the mediastinal area, drainage of any fluid collections, removal of foreign bodies, or obtaining biopsies of tissue for diagnostic purposes. The surgical process begins with an incision made above the suprasternal notch, which is the dip at the top of the sternum, and extends between the borders of the sternocleidomastoid muscle. This incision is then deepened to reach the pretracheal fascia, which is carefully divided to allow further access. The dissection continues down to the superior mediastinum, where the area is opened and thoroughly explored. During this exploration, the surgeon may drain any accumulated fluid, remove foreign objects that may be present, or take biopsies of tissues for further examination. It is important to note that an alternative approach, referred to as a transthoracic or median sternotomy, is described under CPT® Code 39010, which involves a different incision and technique for accessing the mediastinum.

1. Indications

The mediastinotomy with cervical approach is indicated for various clinical scenarios where access to the superior mediastinum is necessary. The following conditions may warrant this procedure:

  • Exploration of Mediastinal Masses - When there is a need to investigate abnormal growths or masses located in the superior mediastinum.
  • Drainage of Mediastinal Abscesses - In cases where there is an accumulation of pus or fluid that requires drainage to alleviate symptoms or prevent complications.
  • Removal of Foreign Bodies - When foreign objects are lodged in the mediastinal area and need to be surgically extracted.
  • Biopsy of Mediastinal Tissue - To obtain tissue samples for histological examination to diagnose conditions such as infections, tumors, or other pathologies.

2. Procedure

The mediastinotomy procedure involves several critical steps to ensure effective access and intervention in the superior mediastinum. The following procedural steps are performed:

  • Step 1: Incision - The procedure begins with the surgeon making an incision above the suprasternal notch, which is located at the top of the sternum. This incision is carefully placed between the borders of the sternocleidomastoid muscle to provide optimal access to the underlying structures.
  • Step 2: Division of Pretracheal Fascia - After the initial incision, the surgeon proceeds to dissect through the layers of tissue until reaching the pretracheal fascia. This fascia is then divided to allow further access to the mediastinal space.
  • Step 3: Dissection to Superior Mediastinum - The dissection continues deeper into the tissue until the superior mediastinum is reached. At this point, the mediastinal space is opened, allowing for exploration and intervention.
  • Step 4: Exploration and Intervention - Once the superior mediastinum is accessed, the surgeon conducts a thorough exploration of the area. This may involve draining any fluid collections, removing foreign bodies, or taking biopsies of tissue as necessary for diagnostic purposes.

3. Post-Procedure

Following the mediastinotomy, patients may require specific post-procedure care to ensure proper recovery. This includes monitoring for any signs of complications such as infection or bleeding. Patients may also need to be observed for respiratory function, especially if the pleural space was entered during the procedure. Pain management will be addressed, and instructions for activity restrictions will be provided to facilitate healing. Follow-up appointments will be necessary to assess the surgical site and review any biopsy results obtained during the 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).
