Official Description

Sternal debridement

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure identified by CPT® Code 21627 refers to sternal debridement, a surgical intervention performed to remove necrotic or infected tissue from the sternum, which is the flat bone located in the center of the chest. This procedure is typically indicated when there is a need to address complications such as infections or non-healing wounds that affect the sternum, often resulting from prior surgeries, trauma, or underlying medical conditions. During the procedure, the patient is placed under general anesthesia to ensure comfort and immobility. The surgeon makes a precise incision in the chest, specifically above the sternum, allowing for direct access to the bone. Once the sternum is visualized, specialized medical instruments are employed to carefully debride the affected area, effectively removing any unhealthy tissue. Following the debridement, the area is thoroughly irrigated to cleanse it of debris and reduce the risk of infection. Finally, the incisions made during the procedure are meticulously closed to promote healing and restore the integrity of the chest wall.

1. Indications

The procedure of sternal debridement is indicated for specific conditions that necessitate the removal of unhealthy tissue from the sternum. These indications may include:

  • Infection The presence of an infection in the sternum, which may arise from surgical complications, trauma, or other underlying health issues.
  • Necrotic Tissue The accumulation of necrotic (dead) tissue that can impede healing and lead to further complications if not addressed.
  • Non-Healing Wounds Chronic wounds or surgical sites that fail to heal properly, potentially due to inadequate blood supply or persistent infection.

2. Procedure

The sternal debridement procedure involves several critical steps to ensure effective treatment of the affected area. The process begins with the patient being placed under general anesthesia, which is essential for ensuring that the patient remains comfortable and pain-free throughout the surgery.

  • Step 1: Incision The surgeon makes a careful incision in the chest, positioned above the sternum. This incision is designed to provide optimal access to the sternum while minimizing trauma to surrounding tissues.
  • Step 2: Visualization The incision is extended until the sternum is fully visualized. This step is crucial as it allows the surgeon to assess the extent of the damage and determine the necessary debridement.
  • Step 3: Debridement Using specialized medical instruments, the surgeon performs the debridement of the sternum. This involves the meticulous removal of any necrotic or infected tissue to promote healing and prevent further complications.
  • Step 4: Irrigation After debridement, the area is thoroughly irrigated. This step is vital for cleansing the surgical site of any remaining debris and reducing the risk of postoperative infection.
  • Step 5: Closure Finally, all incisions made during the procedure are closed. The closure is performed with careful attention to ensure proper healing and restoration of the chest wall integrity.

3. Post-Procedure

Post-procedure care following sternal debridement is essential for optimal recovery. Patients are typically monitored for any signs of complications, such as infection or excessive bleeding. Pain management is also a critical component of post-operative care, and patients may be prescribed analgesics to manage discomfort. Additionally, instructions regarding wound care, activity restrictions, and follow-up appointments will be provided to ensure proper healing. Patients are advised to report any unusual symptoms, such as increased pain, redness, or discharge from the incision site, to their healthcare provider promptly. Overall, the recovery process may vary depending on the individual patient's health status and the extent of the procedure performed.

20700 Add-on Code MPFS Status: Active Code APC N ASC N1 Manual preparation and insertion of drug-delivery device(s), deep (eg, subfascial) (List separately in addition to code for primary procedure)
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.)
AS Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery
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.
GC This service has been performed in part by a resident under the direction of a teaching physician
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.
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.
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).
81 Minimum assistant surgeon: minimum surgical assistant services are identified by adding modifier 81 to the usual procedure number.
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).
