Official Description

Meniscectomy, partial or complete, temporomandibular joint (separate procedure)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 21060 refers to a surgical procedure known as a meniscectomy, which can be either partial or complete, specifically performed on the temporomandibular joint (TMJ). This procedure is classified as a separate procedure, indicating that it is distinct from other surgical interventions that may be performed in conjunction with it. The meniscus is a crucial structure within the TMJ, serving as a cushion and facilitating smooth movement of the joint. During the meniscectomy, the physician makes an incision near the ear to access the joint. Once the meniscus is exposed, a clamp is applied to it, allowing the surgeon to excise all or part of the meniscus as necessary. After the excision, the space left behind may be filled with adjacent tissue or a prosthetic disc to restore function and stability to the joint. Finally, the incision is meticulously closed using layered sutures to promote proper healing and minimize scarring.

1. Indications

The procedure described by CPT® Code 21060 is indicated for various conditions affecting the temporomandibular joint, particularly those involving the meniscus. The following are explicitly provided indications for performing a meniscectomy:

  • TMJ Dysfunction Patients experiencing dysfunction of the temporomandibular joint, which may include pain, limited movement, or clicking sounds during jaw movement.
  • Meniscal Tears Individuals with tears in the meniscus that cause significant pain or impairment in joint function.
  • Degenerative Joint Disease Patients suffering from degenerative conditions affecting the TMJ, leading to deterioration of the meniscus and joint structures.

2. Procedure

The meniscectomy procedure involves several critical steps to ensure effective treatment of the temporomandibular joint. The following procedural steps are outlined:

  • Step 1: Incision The surgeon begins by making a precise incision near the ear, which provides access to the temporomandibular joint. This incision is strategically placed to minimize damage to surrounding tissues and to facilitate a clear view of the joint structures.
  • Step 2: Exposure of the Meniscus After the incision is made, the surgeon carefully dissects through the layers of tissue to expose the meniscus of the joint. This step is crucial as it allows the surgeon to assess the condition of the meniscus and determine the extent of the damage.
  • Step 3: Clamping the Meniscus Once the meniscus is fully exposed, a clamp is applied to it. This clamp helps stabilize the meniscus during the excision process, ensuring that the surgeon can operate with precision and control.
  • Step 4: Excision of the Meniscus The surgeon then proceeds to excise all or part of the meniscus, depending on the specific condition being treated. This excision is performed with care to remove damaged tissue while preserving as much healthy tissue as possible.
  • Step 5: Filling the Space After the meniscus has been excised, the resulting space may be filled with adjoining tissue or a prosthetic disc. This step is important for restoring the joint's function and stability, as it helps to maintain proper alignment and movement of the temporomandibular joint.
  • Step 6: Closure of the Incision Finally, the surgeon closes the incision using layered sutures. This technique promotes optimal healing and minimizes the risk of complications, such as infection or excessive scarring.

3. Post-Procedure

Post-procedure care following a meniscectomy of the temporomandibular joint is essential for ensuring proper recovery. Patients are typically monitored for any immediate complications following the surgery. Pain management may be necessary, and the physician may prescribe analgesics to alleviate discomfort. Patients are advised to follow specific instructions regarding diet, activity level, and oral hygiene to promote healing. Follow-up appointments are crucial to assess the healing process and to determine if any additional interventions are required. Rehabilitation exercises may also be recommended to restore function and mobility to the joint as the patient recovers.

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).
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.
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
