D0364 is the CDT code for cone beam CT capture and interpretation with a limited field of view of less than one whole jaw. It is a focused 3D scan of a specific region, used when a 2D image cannot provide the detail needed for planning or diagnosis.

Use D0364 when you capture and interpret a cone beam CT scan with a limited field of view that covers less than one whole jaw. The scan is focused on a specific region rather than a full arch. The code includes both the image capture and the diagnostic interpretation by the same provider.
Common clinical scenarios: Implant site planning for a single tooth or small area. Evaluating an impacted or ectopic tooth in one region. Assessing a localized pathology or lesion. Examining root morphology or a suspected fracture before endodontic treatment. Looking at a focused area where 2D imaging is not sufficient.
Do NOT use D0364 for: A scan covering one full dental arch (use D0366). A scan covering both jaws (use D0367). A 2D panoramic image (use D0330). An intraoral periapical image (use D0220 or D0230). A scan where capture and interpretation are split between different providers, which uses separate capture-only and interpretation-only codes.

A focused 3D scan covering less than one whole jaw. Capture and interpretation together. Used for a single region such as an implant site or a localized area of interest.
Cone beam capture and interpretation with a field of view of one full dental arch, either the mandible or the maxilla. A larger volume than D0364, covering an entire arch rather than a localized region.
Billing tip: The field of view determines the code. If the scanned volume is less than one whole jaw, use D0364. If it covers one full arch, use D0366. Record the field of view captured so the code matches the actual scan.
Payers want to see why a 3D scan was necessary rather than a 2D image. If the note does not explain the clinical question that required cone beam imaging, the claim can be denied as not medically necessary. Document the indication, such as implant planning or evaluating an impacted tooth, and why 2D would not answer it.
D0364 is limited to less than one whole jaw. If the scan actually covered a full arch or both jaws, the correct code is D0366 or D0367. Billing D0364 for a larger volume is a coding error that can trigger a denial or an audit. Match the code to the field of view captured.
Advanced imaging is often subject to frequency limits. If the patient had a recent cone beam scan within the plan window, an additional scan may be denied. Check the imaging history and benefits before capturing the scan, and provide a narrative when a new scan is clinically required.
Some plans do not cover cone beam imaging at all, or only for specific indications. The claim is denied because the service is excluded, not because of documentation. Verify cone beam coverage and covered indications during eligibility so the patient understands any out of pocket cost before the scan.
Document the clinical question that required a cone beam scan and why a 2D image would not answer it. Implant planning, impacted tooth, localized pathology, or root assessment. This is the primary justification for the code.
Record that the scanned volume was less than one whole jaw. This supports D0364 over the full arch or both jaws codes and shows the smallest appropriate field of view was used.
D0364 includes interpretation. Retain a written interpretation of the scan with the findings. The report demonstrates that the interpretation portion of the service was performed.
Retain the cone beam volume in the patient record. The image is the evidence that the capture was performed and that it covered the stated region.
Confirm the plan covers cone beam imaging for the indication and check frequency limits. Document that prior imaging was reviewed so the scan does not look like a duplicate.

A limited field of view means the scan covers less than one whole jaw. The volume is focused on a specific region, such as a single quadrant or a few teeth, rather than the full arch or both jaws.
D0364 is cone beam capture and interpretation with a limited field of view of less than one whole jaw. D0366 is cone beam capture and interpretation with a field of view of one full dental arch of the mandible or maxilla. The size of the scanned volume determines the code.
Yes. D0364 covers both the capture of the cone beam image and its interpretation. If capture and interpretation are performed by different providers, separate capture-only and interpretation-only codes exist for that scenario.
Common reasons include missing documentation of medical necessity for 3D imaging, frequency limitations, choosing the wrong field of view code, and plans that do not cover cone beam imaging for the stated indication.
Use D0364 when a focused 3D view is clinically necessary and a 2D image would not provide the needed information, such as implant planning, evaluating an impacted tooth, or assessing a localized pathology. Document why 3D imaging was required.
