Official Description

Excision of frenum, labial or buccal (frenumectomy, frenulectomy, frenectomy)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure identified by CPT® Code 40819 involves the excision of the frenum, which can be either labial or buccal. This surgical intervention is commonly known by several terms, including frenumectomy, frenulectomy, or frenectomy. The frenum is a small fold of tissue that connects the lip or cheek to the gums, and in certain cases, it can lead to complications such as the displacement of dentures or interference with periodontal implant tissue. The procedure is performed to alleviate these issues by removing the frenum. During the excision, a diamond-shaped incision is typically made in the frenum to facilitate its removal. In instances where the frenum is broader, a Z-plasty type incision may be employed, which not only excises the frenum but also helps to lengthen the vestibule, thereby improving the overall oral function and aesthetics. This procedure is essential for patients experiencing discomfort or functional limitations due to an abnormal frenum attachment.

1. Indications

The excision of the frenum, as described by CPT® Code 40819, is indicated in specific clinical scenarios where the frenum contributes to dental or periodontal complications. The following conditions may warrant this procedure:

  • Displacement of Dentures The frenum may cause dentures to become misaligned or displaced, leading to discomfort and functional issues for the patient.
  • Proximity to Periodontal Implant Tissue When the frenum is located close to periodontal implant tissue, it can interfere with the stability and health of the implant, necessitating its removal to ensure proper healing and function.

2. Procedure

The procedure for excising the frenum involves several key steps that ensure effective removal while minimizing complications. The following outlines the procedural steps:

  • Step 1: Anesthesia Administration Prior to the procedure, local anesthesia is administered to the patient to ensure comfort during the excision. This step is crucial for minimizing pain and anxiety associated with the surgical intervention.
  • Step 2: Incision Creation A diamond-shaped incision is made in the frenum to facilitate its excision. This incision allows for precise removal of the frenum while preserving surrounding tissue integrity.
  • Step 3: Frenum Excision The frenum is carefully excised from the underlying tissue. This step requires attention to detail to ensure complete removal and to prevent any residual frenum tissue that could lead to recurrence of the issue.
  • Step 4: Alternative Incision Technique (if applicable) In cases where the frenum is broad, a Z-plasty type incision may be utilized. This technique not only removes the frenum but also lengthens the vestibule, enhancing the functional and aesthetic outcomes of the procedure.
  • Step 5: Closure After the frenum has been excised, the incision site is closed, typically using sutures. The closure technique is chosen based on the extent of the incision and the surgeon's preference.

3. Post-Procedure

Following the excision of the frenum, patients may experience some swelling and discomfort at the surgical site. Post-procedure care typically includes recommendations for pain management, which may involve over-the-counter analgesics. Patients are advised to maintain good oral hygiene to prevent infection and promote healing. Additionally, dietary modifications may be suggested to avoid irritation of the surgical site during the initial recovery period. Follow-up appointments may be scheduled to monitor healing and address any concerns that may arise during the recovery process.

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).
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.
