Official Description

Arthroscopy, ankle (tibiotalar and fibulotalar joints), surgical; with removal of loose body or foreign body

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Surgical arthroscopy of the ankle, specifically involving the tibiotalar and fibulotalar joints, is a minimally invasive procedure that allows for direct visualization and intervention within the ankle joint. This procedure is primarily performed to remove loose bodies or foreign objects that may be causing pain, discomfort, or impaired function in the ankle. The term "arthroscopy" refers to the use of an arthroscope, a specialized instrument equipped with a camera and light source, which enables the surgeon to examine the internal structures of the joint without the need for large incisions. The procedure typically involves positioning the patient's leg in a manner that facilitates access to the ankle joint, followed by the creation of small incisions through which the arthroscope and surgical instruments are introduced. The surgeon can then inspect the joint for any signs of injury, disease, or infection, and proceed to remove any identified loose or foreign bodies. This technique not only aids in diagnosing potential issues within the joint but also allows for therapeutic interventions, thereby promoting quicker recovery times and minimizing postoperative complications compared to traditional open surgery.

1. Indications

The procedure is indicated for patients experiencing symptoms related to loose bodies or foreign objects within the ankle joint. These indications may include:

  • Joint Pain Persistent pain in the ankle that may be exacerbated by movement or weight-bearing activities.
  • Swelling Noticeable swelling around the ankle joint, which may indicate inflammation or irritation.
  • Restricted Range of Motion Difficulty in moving the ankle joint freely, which can affect daily activities and overall mobility.
  • Instability A feeling of instability or giving way in the ankle, which may be due to loose bodies interfering with normal joint function.

2. Procedure

The surgical procedure involves several key steps to ensure effective removal of loose or foreign bodies from the ankle joint. These steps include:

  • Positioning the Patient The patient is positioned with the leg resting on an L-shaped bar, ensuring that the thigh is supported while the knee is bent. This positioning allows the lower leg to swing freely, facilitating access to the ankle joint.
  • Preparation of the Ankle Joint The foot is secured in a device known as a bracelet, which helps stabilize the ankle. The joint is then distracted to create space for the surgical instruments, allowing for better visualization and access.
  • Joint Access A needle is inserted into the anteromedial aspect of the ankle joint, and saline is injected to inflate the joint. This inflation helps to distend the joint capsule, making it easier to visualize the internal structures.
  • Creation of the Anteromedial Portal After the joint is inflated, the needle is withdrawn, and an anteromedial portal is created. This portal serves as the entry point for the arthroscope.
  • Insertion of the Arthroscope A trocar is placed into the anteromedial portal, and the arthroscope is inserted through the trocar. This allows the surgeon to inspect the joint for any signs of injury, disease, or infection.
  • Creation of the Anterolateral Portal An additional portal, known as the anterolateral portal, is created to provide further access to the joint. This dual-portal approach enhances the surgeon's ability to navigate within the joint space.
  • Identification and Removal of Loose Bodies The surgeon locates the loose or foreign body within the joint and carefully removes it using specialized instruments. This step is crucial for alleviating symptoms and restoring normal joint function.
  • Joint Flushing After the removal of the loose body, the joint is flushed with saline to clear any remaining debris, ensuring a clean surgical field and promoting healing.
  • Closure of Incisions Upon completion of the procedure, the arthroscope and surgical tools are removed, and the portal incisions are closed, typically using sutures or adhesive strips.

3. Post-Procedure

Following the arthroscopy, patients can expect a recovery period that may involve rest, elevation of the ankle, and the application of ice to reduce swelling. Pain management may be necessary, and patients are often advised to follow specific rehabilitation exercises to restore strength and mobility in the ankle. The healthcare provider will provide detailed instructions regarding activity restrictions and follow-up appointments to monitor the healing process. It is essential for patients to adhere to these guidelines to ensure optimal recovery and prevent complications.

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.
AS Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery
RT Right side (used to identify procedures performed on the right side of the body)
22 Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service.
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).
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.
78 Unplanned return to the operating/procedure room by the same physician or other qualified health care professional following initial procedure for a related procedure during the postoperative period: it may be necessary to indicate that another procedure was performed during the postoperative period of the initial procedure (unplanned procedure following initial procedure). when this procedure is related to the first, and requires the use of an operating/procedure room, it may be reported by adding modifier 78 to the related procedure. (for repeat procedures, see modifier 76.)
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.)
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
81 Minimum assistant surgeon: minimum surgical assistant services are identified by adding modifier 81 to the usual procedure number.
