Official Description

Exploration of penetrating wound (separate procedure); neck

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 20100 refers to the exploration of a penetrating wound in the neck, classified as a separate procedure. This procedure is typically indicated in cases of traumatic injuries, such as those resulting from gunshot or stab wounds. During the exploration, a scalpel is employed to carefully extend the margins of the wound, allowing for a thorough examination of the underlying tissues. The exploration aims to visualize and assess the condition of the subcutaneous tissue, fascia, and muscle, as well as to determine the depth of the penetration. To enhance visibility and facilitate the removal of any debris, the wound is irrigated with normal saline. Following irrigation, the wound undergoes debridement, which involves both sharp and blunt dissection techniques to eliminate non-viable tissue and foreign bodies. Control of any bleeding from minor blood vessels within the subcutaneous tissue, muscle fascia, or muscle is achieved through ligation or coagulation methods. The procedure concludes with an assessment to ensure that the penetrating injury does not compromise deeper structures, such as major blood vessels and nerves, and that, in cases of chest or abdominal wounds, the injury does not extend into the thoracic or abdominal cavity. Depending on the findings, the wound may be packed either open or closed in layers. It is important to use the appropriate CPT® code, 20100, specifically for penetrating wounds of the neck, while code 20103 is designated for similar procedures involving the extremities.

1. Indications

The exploration of a penetrating wound in the neck, as described by CPT® Code 20100, is indicated in the following scenarios:

  • Traumatic Injury A penetrating traumatic wound, such as those caused by gunshot or stab injuries, necessitates exploration to assess the extent of damage.

2. Procedure

The procedure for exploring a penetrating wound in the neck involves several critical steps:

  • Step 1: Wound Extension The initial step involves the use of a scalpel to carefully extend the margins of the penetrating wound. This extension is crucial for gaining access to the underlying tissues that require examination.
  • Step 2: Visualization of Underlying Tissues Once the wound margins are extended, the underlying subcutaneous tissue, fascia, and muscle are visualized. This step is essential for determining the depth of penetration and assessing any potential damage to these structures.
  • Step 3: Irrigation The wound is then irrigated with normal saline. This irrigation serves two purposes: it improves visualization of the wound and helps to remove any debris that may be present, ensuring a clearer view of the tissues involved.
  • Step 4: Debridement Following irrigation, the wound undergoes debridement, which is performed using both sharp and blunt dissection techniques. This process is vital for removing any non-viable tissue and foreign bodies that could impede healing or lead to infection.
  • Step 5: Control of Bleeding During the exploration, any bleeding from minor blood vessels located in the subcutaneous tissue, muscle fascia, or muscle is controlled. This is typically achieved through ligation or coagulation methods to ensure hemostasis.
  • Step 6: Assessment of Deeper Structures After controlling any bleeding, the surgeon assesses whether the penetrating injury involves deeper tissues. It is critical to confirm that major blood vessels and nerves remain intact and, in cases of chest or abdominal wounds, that the injury does not extend into the thoracic or abdominal cavity.
  • Step 7: Wound Closure Finally, based on the findings from the exploration, the wound may be packed either open or closed in layers. This decision is made to promote optimal healing and prevent complications.

3. Post-Procedure

Post-procedure care following the exploration of a penetrating wound in the neck involves monitoring for signs of infection, ensuring proper wound healing, and managing any pain or discomfort. The patient may require follow-up visits to assess the healing process and to address any complications that may arise. Additionally, instructions regarding wound care and activity restrictions may be provided to facilitate recovery.

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).
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).
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).
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.
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.
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.)
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).
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).
