Official Description

Closure of laceration, vestibule of mouth; 2.5 cm or less

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 40830 pertains to the closure of a laceration located in the vestibule of the mouth, specifically when the length of the laceration is 2.5 cm or less. This procedure involves several critical steps to ensure proper healing and aesthetic outcomes. Initially, the wound is thoroughly cleansed to prevent infection, and a local anesthetic is administered to minimize discomfort during the procedure. The healthcare provider inspects the wound to assess its depth and extent, confirming that it involves the mucosa, submucosa, and deeper connective tissues. If necessary, debridement is performed to remove any devitalized tissue, which is essential for promoting healing. Following this, a layered closure technique is employed, which may involve the use of sutures, staples, or tissue adhesive. To reduce tension on the wound and facilitate optimal healing, the tissues are undermined using surgical instruments such as scissors or a scalpel. Control of any bleeding is achieved through chemical means or electrocautery. The closure process begins with the deepest layers of tissue being secured with absorbable sutures, ensuring that the knots are buried to minimize irritation. The superficial layer is then closed with careful attention to aligning and everting the wound edges, which is crucial for preventing a depressed scar. It is important to note that for lacerations exceeding 2.5 cm or those requiring complex repair, CPT® Code 40831 should be utilized, as complex repairs may involve extensive debridement and the use of stents or retention sutures to secure the wound effectively.

1. Indications

The closure of a laceration in the vestibule of the mouth, as described by CPT® Code 40830, is indicated for the following conditions:

  • Traumatic Laceration A laceration resulting from an injury or trauma to the vestibule of the mouth that requires surgical intervention for proper healing.
  • Injury to Oral Mucosa Damage to the mucosal layer of the mouth that necessitates closure to restore integrity and function.
  • Submucosal and Connective Tissue Involvement Lacerations that extend beyond the mucosa into the submucosa and deeper connective tissues, requiring a layered closure approach.

2. Procedure

The procedure for the closure of a laceration in the vestibule of the mouth involves several detailed steps:

  • Step 1: Wound Cleansing The first step involves thoroughly cleansing the laceration site to eliminate any debris or contaminants that could lead to infection. This is a critical preparatory step that ensures a clean working area for the subsequent procedures.
  • Step 2: Administration of Local Anesthetic A local anesthetic is then administered to the patient to minimize pain and discomfort during the procedure. This allows the healthcare provider to perform the necessary interventions without causing undue distress to the patient.
  • Step 3: Wound Inspection The wound is carefully inspected to assess its depth and extent. The provider determines that the laceration involves the mucosa, submucosa, and deeper connective tissue, which guides the approach to closure.
  • Step 4: Debridement If there is any devitalized or non-viable tissue present, debridement is performed to remove this tissue. This step is essential for promoting optimal healing and preventing complications.
  • Step 5: Layered Closure A layered closure technique is employed, utilizing sutures, staples, or tissue adhesive as appropriate. This method ensures that the wound is closed in a way that supports healing and minimizes scarring.
  • Step 6: Tissue Undermining To reduce tension on the wound, the tissues are undermined using surgical instruments such as scissors or a scalpel. This technique helps to facilitate a more effective closure.
  • Step 7: Bleeding Control Any bleeding that occurs during the procedure is controlled using chemical agents or electrocautery, ensuring a clean and stable surgical field.
  • Step 8: Closure of Deepest Layers The deepest layers of tissue are closed with absorbable sutures, and the knots are buried to minimize irritation to the surrounding tissues.
  • Step 9: Closure of Superficial Layer Finally, the superficial layer of the wound is closed, with careful attention to aligning and everting the wound edges. This step is crucial for preventing a depressed scar and ensuring a cosmetically acceptable outcome.

3. Post-Procedure

After the procedure, the patient may be monitored for any immediate complications, such as excessive bleeding or signs of infection. Instructions for post-procedure care typically include keeping the area clean and dry, avoiding trauma to the site, and following up with the healthcare provider as needed. Patients may also be advised on pain management strategies and signs of infection to watch for during the recovery period. The expected recovery time will vary based on individual healing processes, but proper care is essential to ensure optimal healing and minimize scarring.

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.
RT Right side (used to identify procedures performed on the right side of the body)
