Official Description

Debridement, subcutaneous tissue (includes epidermis and dermis, if performed); each additional 20 sq cm, or part thereof (List separately in addition to code for primary procedure)

© 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. Specifically, CPT® Code 11045 refers to the debridement of subcutaneous tissue, which includes the epidermis and dermis if performed. This code is utilized when additional areas of 20 square centimeters or part thereof are debrided, and it is listed separately in addition to the primary procedure code. The process of debridement is critical in managing wounds, as it helps to eliminate devitalized tissue, foreign materials, and any necrotic skin that may impede the healing process. The physician employs sharp excision techniques to remove nonviable tissue until healthy, bleeding tissue is encountered, indicating that viable tissue has been reached. Following the debridement, the physician may choose to close the wound or cover it with gauze to protect the area as it heals. This procedure is essential in various clinical scenarios, particularly in cases of chronic wounds, ulcers, or infections where tissue integrity is compromised.

1. Indications

Debridement using CPT® Code 11045 is indicated for the following conditions:

  • Necrotic Tissue The presence of necrotic or devitalized tissue that requires removal to promote healing.
  • Infected Wounds Wounds that are infected and necessitate the removal of nonviable tissue to prevent further infection.
  • Chronic Ulcers Chronic wounds or ulcers that have not responded to conservative treatment and require surgical intervention.
  • Foreign Material The presence of foreign materials within the wound that must be excised to facilitate proper healing.

2. Procedure

The procedure for debridement as described by CPT® Code 11045 involves several key steps:

  • Assessment of the Wound The physician begins by thoroughly assessing the wound to determine the extent of necrotic tissue and any foreign materials present. This assessment is crucial for planning the debridement process.
  • Preparation of the Area The area surrounding the wound is cleaned and prepared to minimize the risk of infection. This may involve antiseptic solutions and sterile draping.
  • Debridement of Nonviable Tissue Using sharp excision techniques, the physician carefully removes the necrotic epidermis, dermis, and subcutaneous tissue. The goal is to excise all nonviable tissue until healthy, bleeding tissue is encountered, indicating that viable tissue has been reached.
  • Removal of Foreign Material Any foreign materials present in the wound are meticulously removed during the debridement process to ensure a clean wound bed.
  • Wound Management After debridement, the physician may choose to close the wound, apply a dressing, or pack the wound with gauze. The choice of management depends on the size and condition of the wound.

3. Post-Procedure

Post-procedure care following debridement with CPT® Code 11045 includes monitoring the wound for signs of infection, ensuring proper dressing changes, and assessing the healing process. Patients may be advised on wound care techniques and signs to watch for that may indicate complications. Follow-up appointments are typically scheduled to evaluate the healing progress and determine if further debridement or additional interventions are necessary. Pain management may also be addressed as part of the post-procedure care plan.

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.
GW Service not related to the hospice patient's terminal condition
XS Separate structure, a service that is distinct because it was performed on a separate organ/structure
RT Right side (used to identify procedures performed on the right side of the body)
GC This service has been performed in part by a resident under the direction of a teaching physician
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.
LT Left side (used to identify procedures performed on the left side of the body)
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.
