In the world of medical and dental imaging, cone beam radiography (CBCT) is a major advance, offering detailed three-dimensional images of anatomical structures. It is a particularly valuable technology for preoperative planning and complex diagnostics in dentistry. The code LAQK027, specially assigned to this act, standardizes its use and billing within the medical nomenclature. Understanding the functioning and applications of CBCT is therefore essential to take advantage of its clinical advantages, while complying with current legislation.

CBCT: what is it?

Cone Beam Computerized Tomography (CBCT) or Cone Beam Computerized Tomography is a medical imaging technique that allows the capture of detailed three-dimensional images of anatomical structures through the use of a conical X-ray beam.

Unlike conventional radiography, which provides two-dimensional images, CBCT provides a complete volumetric vision, allowing an accurate assessment of hard tissue, teeth and bones. The implementation of the process requires the rotation of a cone beam around the patient, which makes it possible to obtain hundreds of images in a few seconds. Afterwards, these images are digitally reconstructed to form a 3D representation.

Compared to other medical imaging techniques, the Cone Beam therefore makes it possible to visualize complex anatomical structures from different angles and provides better spatial resolution. Compared to a traditional CT scan, it uses a lower radiation dose.

The image quality of cone beam volume radiography may be slightly poor, but it should be noted that it is still a very fast technique. This speed and precision make the Cone Beam particularly advantageous for maxillofacial and dental applications.

Applications of cone beam radiology in medicine and dentistry

The Cone Beam has numerous applications in medicine as well as in dentistry:

Diagnosis of anatomical anomalies in endodontics

In endodontics, cone beam volume radiology is particularly useful for detecting complex anatomical abnormalities such as root fractures or additional root canals. It provides an accurate three-dimensional view, which allows for more accurate diagnosis and appropriate treatment.

Preoperative planning for dental implants

CBCT provides a detailed view of bone structure for dental implant planning. In particular, this allows dentists to identify bone density and the ideal location for implants. The risks of complications are thus minimized.

Study of dentoalveolar and maxillo-mandibular pathologies

The Cone Beam is essential for studying conditions such as jaw infections, tumors, and cysts. The details in the images it provides allow clinicians to plan surgical procedures more accurately and effectively.

Diagnosis of bone pathologies of the temporomandibular joint (TMJ)

Cone Beam Computerized Tomography is very useful for diagnosing TMJ conditions such as disc displacement, arthritis, and other bone abnormalities. By providing clear images of joint and bone structures, this technique allows for accurate assessment and appropriate treatment.

Other potential applications

Apart from the world of ATM evaluation and dentistry, cone beam radiology has applications in ENT to diagnose nasal cavity and sinus pathologies, and in orthopedics to examine fractures and bone deformities. Its increasing use in these areas is only a testament to its effectiveness and versatility.

What are the limitations of Cone Beam Computerized Tomography?

Like any scientific or technological approach, cone beam volume radiology also has limitations.

‍

Limitations for some clinical applications

The Cone Beam is still great for examining bone structures, but compared to traditional scanners, it may be less effective for imaging soft tissue. This limitation reduces its use for certain medical diagnoses.

Need for specific training for practitioners

To use the equipment optimally and to interpret the three-dimensional images correctly, the use of CBCT requires specialized training. The adoption of technology may thus be limited by this training requirement.

High equipment cost

Machines for cone beam radiology represent a significant investment for dental offices and clinics. Regular maintenance and high initial costs may be unaffordable for some practitioners.

Medical nomenclature and the code LAQK027

The code LAQK027 is specifically assigned to the Cone Beam Computerized Tomography (CBCT) act for the evaluation of dental arches, mandible, and maxilla. The LAQK027 code standardizes cone beam volume radiology in the nomenclature of medical procedures, which thus simplifies its billing and reimbursement.

What are the delivery and billing conditions under the code LAQK027?

Certain conditions must be met in order to be able to invoice a CBCT act under the code LAQK027. These include the use of approved equipment, compliance with radiation safety protocols, and the clinical rationale for the examination. In addition, only practitioners who have undergone specific training in the use of cone beam radiology are authorized to perform this procedure.

What are the specific clinical situations for which Cone Beam (LAQK027) is recommended?

The Cone Beam Computerized Tomography (LAQK027) is recommended in dentistry in a variety of situations. These include: the detection of bone pathologies and the evaluation of maxillofacial structures before surgical procedures. It is also used for complex orthodontic evaluations and the diagnosis of temporomandibular joint pathologies.

Precautions and contraindications of Cone Beam (LAQK027)

While the Cone Beam remains a relatively safe approach, it should be noted that due to the potential risks associated with radiation, it is not recommended for pregnant women. For each examination, a rigorous clinical rationale is required and repeated exposure should be limited to the strict minimum. Practitioners should also assess the need for other imaging modalities by being aware of the limitations of CBCT for soft tissue imaging.

Code LAQK027: conditional care

Health Insurance can reimburse the Cone Beam act (LAQK027), but under certain conditions. In fact, recourse to the procedure must necessarily meet one of the indications asked during a preoperative or diagnostic evaluation:

• Bone pathology of the temporomandibular joint;
• dentoalveolar or maxillomandibular pathology;
• Anatomical atypia in endodontics.

A quality assurance program must be respected by the environment. This includes procedures for controlling the quality of examinations, implementation and equipment. It is not allowed to codify the code several times for the examination of several sectors in the same session: it is a fixed price.

Health Insurance does not cover procedures related to the placement of an intraoral implant or an implant assessment, except for the following specific situations:

• Sequelae of a tumor of the maxillaries or the oral cavity;
• Multiple dental agenesis caused by a rare disease.

By entering the mention X on the care sheet in the “CCAM pricing element” column, the practitioner thus attests to his compliance with the conditions of care.

Cone beam radiology, or CBCT, offers numerous benefits in terms of patient comfort, reduced radiation exposure, and image resolution. Its field of application in medicine and dentistry is very broad, with specific uses for treatment planning and diagnostics. This technology is standardized by the LAQK027 code, which simplifies its clinical adoption. With ongoing innovations and increasing integration into care protocols, the Cone Beam has a very promising future.
