D0364 Dental Code (CBCT): Limited Field of View Billing

What D0364 covers

D0364 reports a cone beam CT scan of a limited area, less than one whole jaw, where the provider both captures the image and interprets it. The code bundles two pieces of work into one line: the 3D scan itself and the diagnostic read of that scan, with a written interpretation in the record.

The defining features are the field of view and the bundle. The field of view is limited, a focused volume around a specific site rather than a full arch. The bundle is capture plus interpretation, meaning the same provider who took the scan also read it. Both of those facts have to be true for D0364 to be the right code.

Common clinical situations for a limited CBCT:

• Locating a single impacted or ectopic tooth and its relationship to adjacent roots and nerves.
• Planning an implant at one site, where the bone volume and proximity to the sinus or the inferior alveolar canal matter.
• Evaluating a localized lesion, a suspected root fracture, or a focused endodontic problem that 2D films can’t resolve.

What D0364 is not

• A larger field-of-view scan. A full-arch or both-jaw scan is a different code. Use D0365 (full arch, mandible), D0366 (full arch, maxilla), or D0367 (both jaws, with or without cranium). D0364 is specifically the limited, less-than-one-jaw volume.
• Capture only. If the scan is taken by one provider and read by another, the capture is reported on its own. The capture-only twin of D0364 is D0380 (limited field of view, capture only). D0364 is not a capture-only code.
• Interpretation only. A read performed by a provider who did not take the scan is D0391. D0364 includes the interpretation, so it isn’t the code for a standalone read.
• A 2D radiograph. Panoramic and intraoral films are not CBCT. A panoramic image is D0330. A full-mouth intraoral series is D0210. D0364 is 3D cone beam imaging.

The two axes that drive the CBCT code

Almost every CBCT miscoding traces back to getting one of two axes wrong: the field of view, or the split between capture and interpretation. Get both right and the code is unambiguous.

Axis one: field of view. The capture-and-interpretation series climbs with the size of the scanned area.

• D0364: limited field of view, less than one whole jaw.
• D0365: one full dental arch, mandible.
• D0366: one full dental arch, maxilla.
• D0367: both jaws, with or without the cranium.

The field of view is set on the machine when the scan is taken, so it’s a fact about the scan, not a billing choice. A focused scan of one implant site is D0364. A scan that captures the whole lower arch is D0365, even if the clinical question started small.

Axis two: capture versus interpretation. Each capture-and-interpretation code has a capture-only counterpart, used when one provider scans and a different provider reads.

• Capture and interpretation (same provider does both): D0364 through D0367.
• Capture only (read billed separately by someone else): D0380 (limited), D0381 (mandible), D0382 (maxilla), D0383 (both jaws), plus D0384 for a TMJ series.
• Interpretation only (read by a provider who didn’t capture): D0391.

D0364 versus the capture-only and interpretation-only codes

This is the distinction that separates D0364 from the codes it’s most often confused with. D0380, D0391, and D0364 can all touch the same limited scan, but they describe different scopes of work and rarely belong on the same claim.

D0364 (capture and interpretation) is the single-provider path. Your office owns the machine, takes the limited scan, and your provider reads it and writes the interpretation. One code covers the whole episode.

D0380 (capture only) is for the office that takes the scan but sends it out to be read. It reports the imaging without the interpretation, because the interpretation is coming from someone else.

D0391 (interpretation only) is for the reading provider, an oral and maxillofacial radiologist, for example, who receives a scan they did not capture and produces a diagnostic report. It reports the read without the capture.

In a single-office workflow, D0364 stands alone. The split codes (D0380 paired with D0391) come into play only when the capture and the read actually happen at two different providers. Putting a capture-and-interpretation code on the same claim as a capture-only or interpretation-only code for one scan is the most common way to double-bill CBCT.

Coverage reality: necessity and frequency

CBCT coverage is tighter than coverage for routine radiographs, and it varies enough by plan that you can’t predict it from general benefit knowledge.

• Many plans require documented clinical necessity. Advanced 3D imaging is often covered only when 2D films won’t answer the clinical question, commonly tied to implant planning, surgical evaluation, impaction assessment, or pathology. A vague indication invites a denial.
• Frequency limits are common. Some plans restrict CBCT to once within a multi-year window for the same area, treating it as a high-cost diagnostic rather than a routine image. A scan inside that window can deny even when it’s clinically reasonable.
• Some plans don’t cover CBCT at all. Where the benefit excludes 3D imaging, the scan is patient responsibility, and that’s plan language rather than a coding error to appeal.

Documentation that supports the claim

A CBCT claim is only as strong as the record behind it. The chart should make the field of view and the clinical necessity obvious.

• The imaged area and field of view. State that the scan was a limited field of view, less than one whole jaw, and name the site. This is what keeps D0364 from looking like an undercoded full-arch scan, or an overcoded one.
• Why 3D imaging was needed. The clinical question the scan answered that 2D films could not: implant site assessment, nerve or sinus proximity, an impaction, a suspected fracture, a localized lesion.
• The interpretation. Because D0364 includes the read, the interpretation has to exist in the record. A written report of the findings is what the capture-and-interpretation code is paying for, and it’s what a carrier audit will look for.

For the claim itself, submit the interpretation report and a brief statement of the clinical indication. A one-line narrative naming the imaged site and the diagnostic purpose helps the carrier process the scan against the right benefit and frequency rule.

What to get right in your PMS

The menus differ across Open Dental, Dentrix, Eaglesoft, Curve, and Carestream, but the setup that prevents CBCT miscoding is the same:

1. Keep the field-of-view codes distinct. D0364 (limited), D0365 (mandible), D0366 (maxilla), and D0367 (both jaws) should be separate, clearly labeled entries, so the person posting the claim picks the one that matches the scan the machine actually captured.
2. Separate capture-and-interpretation from capture-only. Make D0364 and D0380 distinct line items with labels that name the difference. One fuzzy “CBCT” entry is how a single-office scan ends up billed as both a capture and a separate read.
3. Flag CBCT for necessity and frequency review. Set CBCT codes to prompt a benefit check before the scan, since coverage hinges on medical necessity and frequency limits that don’t apply to routine radiographs.
4. Attach the interpretation to the claim. The read is what D0364 pays for. Make sure the interpretation report is linked to the claim, not just sitting in the patient record.
