There is more than one CBCT code
A CBCT ADA code depends on the imaged region and whether the service includes both acquisition and interpretation. D0364–D0368 describe combined services; D0380–D0384 cover acquisition alone. D0391 concerns a separate reader’s interpretation and report.
The quick reference below summarizes the American Association of Endodontists’ 2026 guide, pages 6–7. These are plain-language summaries, not the official CDT descriptors.
Combined services, distinguished by imaging scope.
Image capture without the interpretation service.
D0364 is the matching entry in this quick reference. Check the complete current CDT descriptor, actual service, and documentation before selecting a code. A code does not establish coverage.
CBCT ADA / CDT code quick reference
| Code | Imaging scope, summarized |
|---|---|
| D0364 | A region smaller than a full jaw. |
| D0365 | The full lower arch. |
| D0366 | The full upper arch; cranial coverage may be included. |
| D0367 | Upper and lower jaws; cranial coverage may be included. |
| D0368 | A TMJ series involving at least two exposures. |
| Code | Imaging scope, summarized |
|---|---|
| D0380 | A region smaller than a full jaw. |
| D0381 | The full lower arch. |
| D0382 | The full upper arch; cranial coverage may be included. |
| D0383 | Upper and lower jaws; cranial coverage may be included. |
| D0384 | A TMJ series involving at least two exposures. |
Separate interpretation: D0391 concerns a practitioner who did not acquire the images, but reads them and supplies a report.
Check the actual workflow before selecting a code
For a code question, gather the facts before discussing a claim: what imaging was performed, what anatomy was captured, who interpreted it, and what report exists. Then consult the current official CDT entry and the applicable payer requirements. The reference helps identify the question; it cannot decide a patient-specific claim.
The ADA’s coding education resources explain that documenting a procedure and determining a benefit are separate matters. A listed code should not be presented to a practice as a promise that an insurer will pay.

What a CBCT code question means in an equipment conversation
A rep can use a coding question to understand the practice’s workflow: does it acquire images locally, send patients elsewhere, or arrange external interpretation? Ask the practice to describe that process. A code on a public page is not proof that it owns a CBCT unit, needs a replacement, or has a purchase project.
Keep financial assumptions separate from the reference. Ask the practice’s own team to validate any model of collected revenue, outsourcing costs, utilization, and ongoing expenses. Do not multiply a nominal procedure fee by a guessed scan count and present it as a reliable equipment return.
For the wider decision, read how dental clinics make CBCT buying decisions. For account discovery, use the CBCT opportunity framework.
