Does Dental Insurance Cover CBCT Scans? Costs, Billing, and Denials

Dental insurance does cover CBCT scans in many cases, but coverage is never automatic. Insurers treat cone beam computed tomography as advanced imaging that has to be justified by a specific clinical problem the dentist records before taking the scan. If the scan is ordered for routine screening or general diagnosis, expect a denial. If it is ordered for implant planning, a temporomandibular joint problem, a complicated root canal, or another recognized indication, and the dentist documents why a regular X-ray will not do, most dental plans will pay some share of the cost.

What Determines Whether Your Plan Pays

A CBCT scan produces a three-dimensional image of teeth, bone, nerves, and soft tissue around the jaw. It costs more than a standard two-dimensional X-ray and delivers a higher radiation dose, and clinical evidence does not show it improves outcomes for every situation where it might be ordered. Insurers draw a firm line around that: the scan is covered when a dentist needs information a regular X-ray cannot provide, and not covered when a standard image would do the job.

UnitedHealthcare’s dental clinical policy, effective June 2026, states that CBCT is “proven and medically necessary as adjunctive advanced imaging” when clinical conditions require additional detail, and “unproven and not medically necessary for routine dental diagnosis.”¹ Aetna takes the same approach, requiring that a “documented pathologic condition or concern” be identified during the clinical exam and recorded in the patient’s chart before any CBCT is taken.²

Clinical Reasons Insurers Accept

The indications most insurers recognize track the January 2026 consensus recommendations from the American Dental Association and the American Academy of Oral and Maxillofacial Radiology.³ The scenarios that commonly qualify include:

Dental implant planning, including assessing bone volume at the implant site, evaluating the maxillary sinus before augmentation, fabricating surgical guides, and evaluating complications with previously placed implants.¹
Temporomandibular joint disorders, where CBCT is the preferred imaging method for the bony components of the joint, including degenerative disease, condylar resorption, and fractures.⁴
Impacted wisdom teeth, but only when a panoramic X-ray shows the roots are close to the inferior alveolar nerve and that proximity may change the surgical approach. Routine CBCT screening of all wisdom teeth is not covered.⁴
Complex endodontic cases, such as failed root canals, suspected perforations, separated instruments, or external resorption, when two-dimensional imaging cannot explain the symptoms or anatomy.³
Complex periodontal cases where conventional imaging and clinical exam are not enough to plan treatment. Standard full-mouth radiographs remain the first-line tool for periodontal disease.¹
Orthodontic situations involving facial asymmetry or placement of temporary anchorage devices.¹
Autotransplantation, when a tooth is being moved from one site to another and both the donor and recipient sites need to be assessed.

CBCT is not indicated for detecting cavities, and insurers will not pay for it when that is the reason given.⁴

How Major Dental Insurers Handle CBCT

Each insurer sets its own rules, and plans within one insurer vary. The broad contours line up: coverage requires medical necessity, applies to specific procedure codes, and sits inside the plan’s limits on frequency, dollar amounts, and coinsurance.

Delta Dental

Effective January 2024, Delta Dental added CBCT coverage to its PPO and Premier plans, treating the technology as a standard of care for implants, orthodontia, and complex endodontic and periodontic services.⁵ The covered procedure codes are D0364 through D0367, plus D0391 for interpretation by a separate practitioner. Scans are limited to once in a 12-month period, subject to each plan’s coinsurance, exclusions, and annual maximums.⁶ Cosmetic procedures and scans done for purely investigational reasons are excluded.⁷

UnitedHealthcare

UnitedHealthcare recognizes a broad set of CBCT procedure codes, including D0364 through D0368 for capture and interpretation, D0380 through D0384 for capture only, and D0391, D0393, D0394, and D0395 for related interpretation and simulation services. The insurer requires that the field of view be “no larger than necessary to view the region of interest” and that images be read by an appropriately trained professional.¹ UHC’s Texas Medicaid dental plan requires prior authorization for code D0367, with a panoramic X-ray and a narrative explaining the clinical need.⁸

Aetna

Aetna covers CBCT codes D0364 through D0368 and D0380 through D0384 when the scan is justified by a documented condition identified before the scan is taken. Routine CBCT for every new patient or at every recall appointment is explicitly inappropriate under Aetna’s policy, and plans may cap the number or frequency of images allowed.² Aetna’s PPO, PDN, and several other plan types do not require precertification, though the insurer recommends a pretreatment estimate when the course of treatment exceeds $350.⁹

Cigna

Cigna’s dental HMO schedule covers one CBCT scan per calendar year under code D0368 (capture and interpretation for a TMJ series), with a $240 patient charge, when the scan is tied to a TMJ evaluation.¹⁰ Coverage for other CBCT indications under Cigna’s various plan types is less clearly documented and should be verified directly with the plan.

Blue Cross Blue Shield

Coverage varies significantly across BCBS affiliates. Blue Cross Blue Shield of Michigan’s dental medical-surgical treatment policy, reviewed in the third quarter of 2026, lists CBCT imaging under its exclusions.¹¹ Other BCBS affiliates may cover it. Calling the number on the back of the card is the only reliable way to find out.

Medicare

Traditional Medicare does not cover routine dental services, and there is no general provision for dental CBCT or dental implants.¹² Medicare pays for dental work only when it is “inextricably linked” to the clinical success of a covered medical procedure, such as an organ transplant, cardiac valve replacement, or treatment for head and neck cancer, and in the 2026 Physician Fee Schedule rulemaking CMS declined to expand that list.¹³ Medicare Advantage plans often include supplemental dental benefits that go beyond traditional Medicare, and some may cover CBCT.

When the Scan Is Billed to Medical Insurance Instead

If the scan is ordered for a condition that falls under medical rather than dental care, such as TMJ dysfunction, jaw pathology, impacted teeth near a nerve, trauma, or reconstructive surgery, the dentist can bill the patient’s medical insurance. This requires cross-coding to medical CPT codes. The primary code is CPT 70486 (CT scan, maxillofacial area, without contrast), reported alongside CPT 76376 or 76377 when three-dimensional rendering is performed.¹⁴

Medical insurers require an ICD-10 diagnosis code on the claim, such as K01.1 for impacted teeth, and documentation showing why the scan was medically necessary and why a standard panoramic X-ray was not enough.¹⁵ Medical plans may require prior authorization for advanced imaging. Dental implants are generally excluded from medical coverage unless the tooth loss resulted from trauma or jaw pathology, though sleep apnea, sinus disease, and TMJ dysfunction are among the diagnoses that may qualify for medical reimbursement.¹⁴

Confirming Coverage Before the Scan

The single most useful step before a scan is to verify benefits in writing. The ADA recommends requesting a predetermination for complex or costly procedures, which produces the insurer’s written estimate of what will be covered before treatment begins.¹⁶ A predetermination is not a guarantee of payment, since benefits are still determined at the time of service based on eligibility and remaining plan maximums, but it sharply reduces the chance of an unexpected denial.

Ask the dentist for the specific CDT procedure code (typically one of D0364 through D0368) and call the insurer to confirm whether that code is covered, whether prior authorization is required, and what the coinsurance or copay will be. Neither UnitedHealthcare nor Aetna publishes a fixed coinsurance percentage for CBCT; both tie reimbursement to the individual member’s benefit plan document.¹²

What the Scan Costs Without Coverage

When insurance does not cover the scan, or when the patient has a high-deductible plan, the out-of-pocket price generally falls between $100 and $700, depending on the field of view and the provider. A small-field scan of a limited area runs roughly $150 to $350. A medium-field scan covering a quadrant or full arch costs $300 to $450. A large-field scan of both jaws, or one that includes the airway and sinus structures, can reach $400 to $700 or more.¹⁷ Dental schools may offer pricing 50 to 70 percent below private offices, and some practices bundle the scan into the total cost of a larger treatment plan like full-arch implants.¹⁸

If the Claim Is Denied

Many denials come from administrative problems rather than genuine coverage exclusions: incorrect codes, missing documentation, or a lack of pre-authorization. Appeals that address administrative errors succeed more than 70 percent of the time; appeals challenging a medical necessity determination succeed at a lower rate of roughly 15 to 25 percent.¹⁹

Start by reading the Explanation of Benefits to understand the reason for the denial. If it rests on missing information or a coding error, the dentist can often resolve it by resubmitting the correct documentation without a formal appeal.²⁰ A formal appeal must be in writing. Phone calls do not count. Include the original claim number, a narrative explaining the clinical rationale for the scan, and supporting materials such as radiographs, photographs, charting, and clinical notes.²¹ The ADA also advises asking the insurer’s dental consultant to speak directly with the treating dentist before a final denial is issued.

Most policies allow 60 to 180 days from the denial date to file an appeal, and some plans require it within as few as 90 days.²² If internal appeals fail, the next step is the state’s dental insurance ombudsman or insurance commissioner’s office.
