Official Description

Vermilionectomy (lip shave), with mucosal advancement

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure known as vermilionectomy, specifically coded as CPT® Code 40500, involves the surgical removal of the vermilion portion of the lip, which is the pink to red area that is composed of modified mucosal membrane. The lips are anatomically divided into three distinct regions: the cutaneous, vermilion, and mucosal areas. The cutaneous region of the upper lip extends from the base of the nose to the nasolabial folds, while the lower cutaneous lip stretches from the vermilion border to the nasolabial folds and down to the mental crease at the chin. The vermilion area is crucial for aesthetic and functional purposes, and its excision is typically indicated for various pathological conditions. Vermilionectomy is performed to address issues such as actinic cheilitis, carcinoma in situ, and squamous cell carcinoma affecting the vermilion. During the procedure, an incision is made along the vermilion border of the affected lip, allowing for the excision of the vermilion tissue along the submucosal plane. Following this, the posterior lip mucosa is incised and developed to facilitate the reconstruction of the vermilion. The mucosal tissue is then advanced and carefully sutured to the cutaneous lip, effectively reconstructing the vermilion area.

1. Indications

The procedure of vermilionectomy is indicated for several specific conditions affecting the vermilion area of the lips. These indications include:

  • Actinic Cheilitis - A precancerous condition caused by prolonged sun exposure, leading to changes in the texture and color of the vermilion.
  • Carcinoma in Situ - A localized form of cancer that has not invaded surrounding tissues, often requiring surgical intervention to prevent progression.
  • Squamous Cell Carcinoma of the Vermilion - A type of skin cancer that can arise in the vermilion area, necessitating excision to ensure complete removal of malignant cells.

2. Procedure

The vermilionectomy procedure involves several critical steps to ensure effective removal and reconstruction of the vermilion area. The steps are as follows:

  • Step 1: Incision - The surgeon begins by making an incision along the vermilion border of the affected lip, which may be either the upper or lower lip. This incision is strategically placed to allow for the excision of the vermilion tissue while preserving surrounding structures.
  • Step 2: Excision of Vermilion - Following the incision, the surgeon excises the vermilion tissue along the submucosal plane. This careful dissection is crucial to remove the diseased tissue while minimizing damage to adjacent healthy tissues.
  • Step 3: Incision of Posterior Lip Mucosa - After the vermilion has been excised, the posterior lip mucosa is incised. This step is essential for developing the mucosal tissue, which will be used to reconstruct the vermilion area.
  • Step 4: Mucosal Advancement - The lip mucosa is then advanced forward to cover the excised vermilion area. This advancement is performed meticulously to ensure proper alignment and tension-free closure.
  • Step 5: Suturing - Finally, the advanced mucosal tissue is sutured to the cutaneous lip. This suturing is done with precision to reconstruct the vermilion and restore the aesthetic and functional integrity of the lip.

3. Post-Procedure

Post-procedure care following a vermilionectomy is essential for optimal healing and recovery. Patients are typically advised to follow specific instructions regarding wound care to prevent infection and promote healing. This may include keeping the surgical site clean and dry, avoiding certain foods that could irritate the area, and adhering to any prescribed medication for pain management. Patients should also be monitored for any signs of complications, such as excessive swelling, bleeding, or infection. Follow-up appointments are crucial to assess the healing process and ensure that the reconstruction of the vermilion is successful.

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.
