Official Description

Repair lip, full thickness; up to half vertical height

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 40652 involves a full-thickness repair of the lip, specifically addressing injuries that affect up to half of the vertical height of the lip. The lips are anatomically divided into three distinct regions: the cutaneous, vermilion, and mucosal areas. The cutaneous region encompasses the outer skin of the lip, while the vermilion region is the pinkish-red area that is more delicate and composed of modified mucosal membrane. The mucosal portion is located inside the mouth and is adjacent to the teeth. In the context of this procedure, a full-thickness repair means that all layers of the lip, including skin, muscle, and mucosa, are involved in the repair process. The surgical technique requires careful alignment of the vermilion border to ensure aesthetic outcomes, and the repair is performed in a specific sequence to promote optimal healing and minimize scarring. This procedure is indicated for lacerations that do not exceed half of the vertical height of the lip, distinguishing it from more extensive repairs that may require additional techniques or considerations.

1. Indications

The procedure described by CPT® Code 40652 is indicated for the repair of full-thickness lip lacerations that affect up to half of the vertical height of the lip. This may include injuries resulting from trauma, surgical procedures, or other causes that compromise the structural integrity of the lip. The specific indications for this procedure include:

  • Traumatic Lacerations Lacerations caused by accidents or injuries that penetrate through the full thickness of the lip.
  • Surgical Repair Surgical interventions that necessitate the reconstruction of the lip due to previous procedures or congenital defects.
  • Cosmetic Restoration Situations where the aesthetic appearance of the lip is compromised and requires surgical intervention to restore form and function.

2. Procedure

The procedure for CPT® Code 40652 involves several critical steps to ensure a successful repair of the lip. The steps are as follows:

  • Step 1: Initial Assessment The surgeon begins by assessing the extent of the laceration to determine that it does not exceed half of the vertical height of the lip. This assessment is crucial for selecting the appropriate coding and surgical approach.
  • Step 2: Submucosal Repair The repair process starts with the closure of the submucosa using small-caliber, soft, nonirritating suture material. The knots of the sutures are buried to minimize irritation and promote healing.
  • Step 3: Muscle Repair Following the submucosal repair, the orbicularis oris muscle is repaired using absorbable sutures. This step is essential for restoring the functional integrity of the lip.
  • Step 4: Vermilion Repair The vermilion portion of the lip is then repaired, with careful attention to aligning the vermilion border to ensure a natural appearance post-surgery.
  • Step 5: Cutaneous Closure The dermis and subcutaneous tissue of the cutaneous lip are closed next, followed by the closure of the epidermis. The epidermis is everted to prevent depression and minimize scarring.
  • Step 6: Mucosal Involvement If the mucosa is involved due to a through-and-through laceration, it may be closed either before or after the repair of the vermilion and cutaneous lips, depending on the surgeon's preference and the specific circumstances of the injury.

3. Post-Procedure

After the completion of the repair procedure, post-operative care is essential for optimal recovery. Patients are typically advised to follow specific instructions regarding wound care to prevent infection and promote healing. This may include keeping the area clean and dry, avoiding certain foods that could irritate the repair site, and possibly using prescribed topical ointments. Follow-up appointments are important to monitor the healing process and to assess the cosmetic outcome of the repair. Patients should also be informed about signs of complications, such as increased swelling, redness, or discharge, which may require further medical attention.

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).
54 Surgical care only: when 1 physician or other qualified health care professional performs a surgical procedure and another provides preoperative and/or postoperative management, surgical services may be identified by adding modifier 54 to the usual procedure number.
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.
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.)
