Is a CBCT scan safe for patients?

Yes, CBCT scans are generally safe. They use a lower dose of radiation compared to traditional CT scans, but precautions are always taken to minimize exposure.

Can D0366 be used for both arches?

No, D0366 specifically covers the capture and interpretation of a CBCT scan for one full dental arch, the maxilla. A separate code may be needed for the mandible.

How often can a CBCT scan be performed?

The frequency of CBCT scans depends on clinical necessity and insurance coverage. It is important to check with the patient's insurance provider for specific limitations.

What should be included in the interpretation report for D0366?

The interpretation report should include a detailed analysis of the CBCT images, noting any abnormalities, bone quality, and other relevant findings that impact treatment planning.

Cone Beam CT Capture - CDT Code Guide

Diagnostic/Image Capture with Interpretation

Overview

CDT code D0366 refers to the capture and interpretation of a cone beam computed tomography (CBCT) image with a field of view covering one full dental arch, specifically the maxilla, with or without including the cranium. This diagnostic procedure is essential for providing detailed three-dimensional images that help in the assessment of dental structures, bone quality, and pathology. It is particularly useful in planning complex dental treatments such as implant placement, orthodontics, and maxillofacial surgery. The CBCT scan offers high-resolution images that are crucial for accurate diagnosis and treatment planning, ensuring better outcomes for patients.

When to Use This Code

Pre-implant assessment to evaluate bone structure and quality.
Orthodontic evaluation to assess jaw and tooth alignment.
Maxillofacial surgery planning to visualize anatomical structures.
Diagnosis of complex dental pathologies such as cysts or tumors.
Assessment of sinus issues related to dental health.

Documentation Requirements

Detailed patient history and clinical indications for the scan.
Written order from a licensed dentist or specialist.
Clear documentation of the interpretation of the CBCT images.
Patient consent form for the imaging procedure.
Record of the date and time of the procedure.
Storage of images in a secure, accessible format for future reference.

Billing Considerations

When billing for D0366, it is important to note any frequency limitations imposed by insurance providers, as repeated scans may not be covered. Common modifiers include those indicating the specific arch scanned. Ensure that the procedure is medically necessary and documented thoroughly to avoid claim denials. Coordination with insurance companies regarding coverage for CBCT scans is advisable, as policies may vary.
