Cone Beam Computed Tomography (CBCT) Coding

CPT codes for Cone Beams

Cone beam computed tomography (or CBCT, also referred to as C-arm CT, cone beam volume CT, or flat panel CT) is a medical imaging technique consisting of X-ray computed tomography where the X-rays are divergent, forming a cone.

There is actually not currently a specific CPT code for CBCT……the closest CPT code is: 70486 - Computed tomography, maxillofacial area; without contrast material. Many offices have been using this for some time for CBCT, however, some medical insurers are auditing that code when used for CBCT because the description does not specify “cone beam”.

So, “76497 - Unlisted computed tomography procedure (eg, diagnostic, interventional)” is a good CPT option to consider (since it is an “unlisted” code, a narrative report describing the procedure is highly recommended). Also, many offices choose to put their cone beam CT into “tomography” mode and billing for a TMJ tomography instead (76102).

Or, some medical insurers will process the “D” codes for procedures when there is not a specific CPT code available……

For example, here are the “D” codes from HealthPartner’s medical policy for “Cone-beam computed tomography (CT) scan for medically-related dental services”

D0363 - Cone-Beam 3D multi image reconstruction

D0364 - Cone beam CT capture and interpretation with limited field of view - less than one whole jaw

D0365 - Cone beam CT capture and interpretation with field of view of one full dental arc - mandible

D0366 - Cone beam CT capture and interpretation with field of view of one full dental arch - maxilla, with or without cranium

D0367 - Cone beam CT capture with interpretation with field of view of both jaws, with or without cranium

D0368 - Cone beam CT capture and interpretation for TMJ series including two or more exposures

D0380 - Cone beam CT image capture with limited field of view - less than one whole jaw

D0381 - Cone beam CT image capture with field of view of one full dental arch - mandible

D0382 - Cone beam CT image capture with field of view of one full dental arch - maxilla, with or without cranium

D0383 - Cone beam CT image capture with field of view of both jaws, with or without cranium

D0384 - Cone beam CT image capture for TMJ series including two or more exposures
