Official Description

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

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Debridement is a surgical procedure aimed at removing dead, damaged, or infected tissue to promote healing and prevent infection. In the context of CPT® Code 11044, this specific code refers to the debridement of bone, which includes the removal of epidermis, dermis, subcutaneous tissue, muscle, and/or fascia if performed. The procedure is indicated when there is a need to eliminate devitalized tissue and foreign material from a wound, ensuring that only viable tissue remains. The process begins with the identification of nonviable tissue, which is then excised using sharp instruments until healthy, bleeding tissue is encountered. This thorough removal is crucial for the healing process, as it helps to reduce the risk of infection and facilitates the body's natural healing mechanisms. The procedure is typically performed on wounds that are larger than 20 square centimeters, and the code specifically applies to the first 20 square centimeters of tissue that is debrided. For larger areas, additional codes are utilized to account for each subsequent 20 square centimeters or part thereof. The physician may choose to close the wound, pack it with gauze, or place a drain, depending on the extent of the debridement and the condition of the surrounding tissue.

1. Indications

Debridement of Bone This procedure is indicated for wounds that involve necrotic or devitalized bone, necessitating the removal of nonviable tissue to promote healing and prevent infection.

  • Infection Presence of infection in the bone or surrounding tissues that requires debridement to eliminate infected tissue.
  • Necrosis Areas of necrotic bone that must be removed to allow for proper healing and restoration of function.
  • Foreign Material The presence of foreign material within the wound that could impede healing and increase the risk of infection.

2. Procedure

Step 1: Assessment The physician begins by assessing the wound to determine the extent of necrosis and the presence of foreign material. This assessment is crucial for planning the debridement process.

Step 2: Anesthesia Local or general anesthesia may be administered to ensure patient comfort during the procedure, depending on the size and location of the wound.

Step 3: Debridement Using sharp excision techniques, the physician removes nonviable epidermis, dermis, subcutaneous tissue, muscle, and fascia as necessary. The goal is to reach viable tissue, which is indicated by bleeding. This step may involve careful dissection to avoid damaging surrounding healthy tissue.

Step 4: Bone Debridement The physician then focuses on the bone, removing all devascularized bone until healthy, bleeding bone is encountered. This step is critical to ensure that the underlying bone is viable and can support healing.

Step 5: Wound Management After debridement, the physician may choose to close the wound, pack it with gauze, or place a drain to facilitate drainage and prevent fluid accumulation. The choice of wound management technique depends on the extent of the debridement and the condition of the surrounding tissue.

3. Post-Procedure

Post-procedure care involves monitoring the wound for signs of infection and ensuring proper healing. The physician may provide specific instructions regarding wound care, including how to change dressings and when to return for follow-up visits. Patients are typically advised to keep the area clean and dry, and to report any signs of increased redness, swelling, or discharge. The recovery process may vary depending on the extent of the debridement and the patient's overall health, but regular follow-up appointments are essential to assess healing and determine if further intervention is necessary.

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

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).
74 Discontinued out-patient hospital/ambulatory surgery center (asc) procedure after administration of anesthesia: due to extenuating circumstances or those that threaten the well being of the patient, the physician may terminate a surgical or diagnostic procedure after the administration of anesthesia (local, regional block(s), general) or after the procedure was started (incision made, intubation started, scope inserted, etc). under these circumstances, the procedure started but terminated can be reported by its usual procedure number and the addition of modifier 74. note: the elective cancellation of a service prior to the administration of anesthesia and/or surgical preparation of the patient should not be reported. for physician reporting of a discontinued procedure, see modifier 53.
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.
77 Repeat procedure by another physician or other qualified health care professional: it may be necessary to indicate that a basic procedure or service was repeated by another physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 77 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
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).
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.
