Official Description

Debridement, muscle and/or fascia (includes epidermis, dermis, and subcutaneous tissue, if performed); first 20 sq cm or less

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Debridement is a surgical procedure that involves the removal of dead, damaged, or infected tissue to promote healing and prevent infection. In the context of CPT® Code 11043, this procedure specifically refers to the debridement of muscle and/or fascia, which includes the removal of the epidermis, dermis, and subcutaneous tissue if performed. The primary goal of this procedure is to eliminate nonviable tissue, which can impede the healing process and serve as a potential source of infection. During the debridement process, the physician utilizes sharp excision techniques to carefully remove devitalized tissue until healthy, bleeding tissue is encountered. This ensures that the wound is clean and conducive to healing. Additionally, any foreign material present in the wound is also removed to further reduce the risk of complications. After the debridement is completed, the physician may choose to close the wound, cover it with gauze, or place a drain to facilitate further healing. CPT® Code 11043 is specifically designated for the debridement of the first 20 square centimeters of tissue, with additional codes available for larger areas of debridement.

1. Indications

The procedure described by CPT® Code 11043 is indicated for the removal of nonviable muscle and/or fascia tissue in various clinical scenarios. The following conditions may warrant this procedure:

  • Necrotizing fasciitis - A severe bacterial infection that destroys skin, fat, and the tissue covering the muscles.
  • Chronic non-healing wounds - Wounds that have not shown improvement despite appropriate treatment, often due to the presence of devitalized tissue.
  • Traumatic injuries - Injuries that result in significant tissue damage, necessitating the removal of nonviable tissue to promote healing.
  • Infected surgical wounds - Post-surgical wounds that have become infected and require debridement to remove necrotic tissue and reduce the risk of further complications.

2. Procedure

The procedure for CPT® Code 11043 involves several critical steps to ensure effective debridement of muscle and/or fascia. The following procedural steps are outlined:

  • Step 1: Preparation - The area surrounding the wound is prepared using aseptic techniques to minimize the risk of infection. This may involve cleaning the skin and applying sterile drapes.
  • Step 2: Anesthesia - Local or general anesthesia is administered to ensure the patient is comfortable and pain-free during the procedure.
  • Step 3: Incision and Exposure - An incision is made to access the affected area. The surgeon carefully exposes the muscle and fascia while taking care to preserve healthy tissue.
  • Step 4: Debridement - Using sharp excision techniques, the surgeon removes all nonviable muscle and fascia tissue. This is done until viable tissue is encountered, which is indicated by the presence of bleeding. The surgeon inspects the muscle tissue for viability by assessing color, consistency, contraction, and circulation.
  • Step 5: Irrigation - The wound is thoroughly irrigated to remove any debris and foreign material, ensuring a clean surgical field.
  • Step 6: Closure or Packing - Once all nonviable tissue has been excised, the wound may be closed, packed with gauze, or a drain may be placed to facilitate healing and prevent fluid accumulation.

3. Post-Procedure

After the debridement procedure is completed, the patient will require specific post-procedure care to promote healing and monitor for any complications. The wound should be kept clean and dry, and the patient may be instructed on how to care for the wound at home. Follow-up appointments are essential to assess the healing process and determine if further debridement or additional interventions are necessary. Signs of infection, such as increased redness, swelling, or discharge, should be reported to the healthcare provider immediately. Pain management may also be addressed, and the patient may be prescribed analgesics as needed. Overall, proper post-procedure care is crucial for optimal recovery and healing outcomes.

GW Service not related to the hospice patient's terminal condition
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.
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.
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.)

QX Crna service: with medical direction by a physician
X4 Episodic/focused services: for reporting services by clinicians who provide focused care on particular types of treatment limited to a defined period and circumstance; the patient has a problem, acute or chronic, that will be treated with surgery, radiation, or some other type of generally time-limited intervention; reporting clinician service examples include but are not limited to, the orthopedic surgeon performing a knee replacement and seeing the patient through the postoperative period
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.
24 Unrelated evaluation and management service by the same physician or other qualified health care professional during a postoperative period: the physician or other qualified health care professional may need to indicate that an evaluation and management service was performed during a postoperative period for a reason(s) unrelated to the original procedure. this circumstance may be reported by adding modifier 24 to the appropriate level of e/m service.
25 Significant, separately identifiable evaluation and management service by the same physician or other qualified health care professional on the same day of the procedure or other service: it may be necessary to indicate that on the day a procedure or service identified by a cpt code was performed, the patient's condition required a significant, separately identifiable e/m service above and beyond the other service provided or beyond the usual preoperative and postoperative care associated with the procedure that was performed. a significant, separately identifiable e/m service is defined or substantiated by documentation that satisfies the relevant criteria for the respective e/m service to be reported (see evaluation and management services guidelines for instructions on determining level of e/m service). the e/m service may be prompted by the symptom or condition for which the procedure and/or service was provided. as such, different diagnoses are not required for reporting of the e/m services on the same date. this circumstance may be reported by adding modifier 25 to the appropriate level of e/m service. note: this modifier is not used to report an e/m service that resulted in a decision to perform surgery. see modifier 57 for significant, separately identifiable non-e/m services, see modifier 59.
26 Professional component: certain procedures are a combination of a physician or other qualified health care professional component and a technical component. when the physician or other qualified health care professional component is reported separately, the service may be identified by adding modifier 26 to the usual procedure number.
50 Bilateral procedure: unless otherwise identified in the listings, bilateral procedures that are performed at the same session, should be identified by adding modifier 50 to the appropriate 5 digit code. 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).
53 Discontinued procedure: under certain circumstances, the physician or other qualified health care professional may elect to terminate a surgical or diagnostic procedure. due to extenuating circumstances or those that threaten the well being of the patient, it may be necessary to indicate that a surgical or diagnostic procedure was started but discontinued. this circumstance may be reported by adding modifier 53 to the code reported by the individual for the discontinued procedure. note: this modifier is not used to report the elective cancellation of a procedure prior to the patient's anesthesia induction and/or surgical preparation in the operating suite. for outpatient hospital/ambulatory surgery center (asc) 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).
56 Preoperative management only: when 1 physician or other qualified health care professional performed the preoperative care and evaluation and another performed the surgical procedure, the preoperative component may be identified by adding modifier 56 to the usual procedure number.
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.
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).
95 Synchronous telemedicine service rendered via a real-time interactive audio and video telecommunications system: synchronous telemedicine service is defined as a real-time interaction between a physician or other qualified health care professional and a patient who is located at a distant site from the physician or other qualified health care professional. the totality of the communication of information exchanged between the physician or other qualified health care professional and the patient during the course of the synchronous telemedicine service must be of an amount and nature that would be sufficient to meet the key components and/or requirements of the same service when rendered via a face-to-face interaction. modifier 95 may only be appended to the services listed in appendix p. appendix p is the list of cpt codes for services that are typically performed face-to-face, but may be rendered via a real-time (synchronous) interactive audio and video telecommunications system.
