Official Description

Debridement including removal of foreign material at the site of an open fracture and/or an open dislocation (eg, excisional debridement); skin, subcutaneous tissue, muscle fascia, and muscle

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 11011 refers to a specific surgical procedure known as debridement, which involves the removal of foreign material from the site of an open fracture and/or an open dislocation. This procedure is critical in managing contaminated wounds, as it helps to prevent infection and promote healing. During the debridement process, the surgeon meticulously explores the injury site to identify and remove any irreparable or nonviable tissue, which may include ischemic or necrotic areas. The procedure begins with copious irrigation of the wound to eliminate as much foreign matter and bacteria as possible, ensuring a cleaner surgical field. Following this, a new sterile field is established for further surgical exploration and debridement of the contaminated wound. The surgeon employs sharp dissection techniques to enlarge the wound, allowing for better visualization of the underlying structures. Nonviable margins of the wound are carefully excised, and dissection may extend through the subcutaneous tissue, fascia, muscle, and even bone, depending on the extent of contamination and tissue viability. Muscle tissue is assessed for viability by evaluating its color, consistency, contraction, and circulation. The fascia is incised parallel to the muscle fibers, and any nonviable muscle tissue is excised. Additionally, contaminated or nonviable cortical bone may be removed using a chisel. Throughout the procedure, care is taken to protect vital structures such as blood vessels, nerves, tendon sheaths, viable periosteum, and soft tissue attached to the bone. Once all nonviable tissue has been adequately removed, indicated by the presence of bleeding from the exposed surfaces, the physician may choose to close the wound or leave it open for drainage. This code is specifically used for debridement that involves skin, subcutaneous tissue, fascia, and muscle, distinguishing it from other codes that pertain to different levels of tissue involvement.

1. Indications

The procedure associated with CPT® Code 11011 is indicated for the management of open fractures and/or open dislocations that are contaminated with foreign material. The following conditions may warrant the performance of this procedure:

  • Open Fracture: A fracture where the bone is exposed through the skin, often accompanied by contamination from external sources.
  • Open Dislocation: A dislocation where the joint surfaces are exposed through the skin, requiring debridement to remove foreign material and prevent infection.
  • Contaminated Wounds: Wounds that contain foreign materials such as dirt, gravel, glass, or metal, necessitating thorough cleaning and debridement to promote healing.
  • Nonviable Tissue: Presence of ischemic or necrotic tissue that must be excised to facilitate proper healing and prevent complications.

2. Procedure

The procedure for CPT® Code 11011 involves several critical steps to ensure effective debridement of the contaminated wound:

  • Initial Irrigation: The wound is first irrigated copiously to remove as much foreign matter and bacteria as possible. This step is essential to reduce the risk of infection and prepare the wound for further surgical intervention.
  • Creation of a Sterile Field: After irrigation, a new sterile field is established to ensure a clean environment for surgical exploration and debridement of the grossly contaminated wound.
  • Wound Exploration: The surgeon performs sharp dissection to enlarge the wound, allowing for better visualization of the underlying structures. This exploration is crucial for identifying nonviable tissue and assessing the extent of contamination.
  • Excising Nonviable Tissue: Nonviable wound margins are carefully excised. The dissection continues through the subcutaneous tissue into the fascia, muscle, and bone as necessary, ensuring that all nonviable tissue is removed.
  • Assessment of Muscle Viability: Muscle tissue is inspected for viability by checking color, consistency, contraction, and circulation. This assessment helps determine which muscle tissue can be preserved and which must be excised.
  • Incising the Fascia: The fascia is incised parallel to the muscle fibers, allowing for the identification and excision of any nonviable muscle tissue.
  • Bone Debridement: Contaminated or nonviable cortical bone is excised using a chisel, ensuring that all sources of infection are removed from the wound.
  • Removal of Foreign Material: Any foreign material present in the wound is meticulously removed to further reduce the risk of infection and promote healing.
  • Closure or Drainage: Once all nonviable tissue has been removed, indicated by bleeding from the exposed surfaces, the physician may choose to close the wound or leave it open to drain, depending on the clinical situation.

3. Post-Procedure

After the debridement procedure associated with CPT® Code 11011, appropriate post-procedure care is essential for optimal recovery. The wound may be left open to drain, which allows for continued monitoring and management of any potential infection. If the wound is closed, careful attention must be paid to signs of infection or complications. Follow-up appointments are typically scheduled to assess the healing process and determine if further interventions are necessary. Patients may be advised on wound care, signs of infection to watch for, and any restrictions on activity to promote healing. The overall goal of post-procedure care is to ensure proper recovery and prevent complications associated with the open fracture and/or dislocation.
