If your dental practice bills UnitedHealthcare for a CBCT scan and an office visit on the same day, there is a new documentation requirement you need to have in place now. Effective April 1, 2026, UnitedHealthcare will no longer separately reimburse the professional component of a radiology service billed on the same date as an evaluation and management (E/M) visit — unless the provider submits a separate, full written interpretation and report.

Without that written report, UHC treats the image review time as already included in the E/M payment. You will not receive additional reimbursement for the CBCT interpretation, regardless of how the claim is coded.

⚠ What This Means for Your Practice

If you perform an exam and a CBCT on the same patient, same day, and bill both to UnitedHealthcare without submitting a compliant written radiology report, the CBCT professional component will be bundled into your office visit payment. You lose separate reimbursement for the scan interpretation.

What the Policy Says

UHC Policy — Effective April 1, 2026
"When the same provider bills an evaluation and management (E/M) service and a global radiology code for the same patient on the same date of service, UnitedHealthcare requires a full written interpretation and report consistent with American College of Radiology (ACR) guidelines in order to separately reimburse the professional component of the radiology service. If no written report is submitted, the professional component is considered included in the E/M payment."
UHC Enhanced Professional/Technical Component Policy, April 2026

This policy applies to globally billed radiology services and to services billed with modifier 26 (Professional Component). It covers UnitedHealthcare commercial plans across the board.

Why This Affects Dental Practices Specifically

Dental practices billing medical insurance for CBCT scans — whether for sleep medicine workups, implant planning, TMJ evaluation, or oral surgery — routinely perform both a patient examination and cone beam imaging on the same visit. Under dental billing convention, the image review has historically been considered part of the comprehensive exam.

Under medical billing rules, however, the CBCT is a separate billable service — and UHC is now drawing a hard line: the interpretation must be documented separately and in writing, or it gets absorbed into the exam fee.

This is not a gray area or a technicality. UHC has explicitly stated that the radiology report must be attached to the claim when billing both an E/M and a global radiology code on the same date. If it is not there, the professional component of the CBCT will not be reimbursed separately.

What Counts as a Compliant Written Report

UHC requires the written interpretation report to be consistent with American College of Radiology (ACR) guidelines. ACR-compliant radiology reports for CBCT scans should include all of the following elements:

CBCT Interpretation Report — Required Elements

✓
Patient demographics — name, date of birth, date of service
✓
Clinical indication — the specific reason the study was ordered (e.g., evaluation of airway anatomy for suspected OSA, pre-surgical implant planning, TMJ evaluation)
✓
Technique / protocol — field of view, slice thickness, exposure parameters, and equipment used
✓
Findings — detailed, systematic description of what is observed in the scan (bone density, anatomical structures, pathology, airway measurements if applicable)
✓
Impression / conclusion — the interpreting provider's clinical interpretation of the findings and any diagnostic conclusions
✓
Provider signature — name, credentials, NPI, and date of interpretation (which may differ from the date of service)
⚠ Important Distinction

A SOAP note or chart entry that references the CBCT findings is not the same as a written interpretation report. UHC requires a standalone radiology report — not notes embedded in the encounter documentation. If your current workflow documents image findings inside the exam note rather than in a separate report, it will not satisfy this requirement.

The Correct Billing Sequence for Same-Day E/M + CBCT

  1. 1
    Perform and document the E/M visit

    Complete the examination and document it as you normally would. The E/M code (99202–99215 or equivalent) covers the clinical evaluation, history, and medical decision-making.

  2. 2
    Perform and interpret the CBCT

    Acquire the cone beam scan. The interpretation must be performed as a separate, distinct clinical activity — not simply a passing review during the exam.

  3. 3
    Generate a standalone written radiology interpretation report

    Produce a complete, ACR-consistent written report covering all required elements (clinical indication, technique, findings, impression, signature). This report must exist as a separate document — not embedded in the exam note.

  4. 4
    Bill both services with the appropriate codes

    Submit the E/M code and the appropriate radiology code (e.g., 70486, 70487, or 70488 for maxillofacial CT; D0330 on dental claims). Use modifier 26 if billing the professional component separately from the technical component.

  5. 5
    Attach the written report to the claim

    When submitting to UHC, attach a copy of the signed radiology interpretation report to the claim. Without this attachment, the professional component will be bundled and not separately reimbursed.

What Happens Without the Report

UnitedHealthcare's position is straightforward: if you reviewed the CBCT images without producing a full written interpretation report, the review time is considered part of the E/M service and included in that payment. You will receive the E/M reimbursement only. The radiology code will be denied or bundled.

This means that practices billing both services but not submitting the written report are effectively doing the clinical work of a CBCT interpretation and receiving no additional payment for it. Over time, across multiple patients and multiple dates of service, this represents significant lost reimbursement.

✓ Practice Tip

Build a CBCT interpretation report template into your practice management system or EHR so that every scan automatically generates a structured report document. The template does the heavy lifting — the provider fills in the findings and impression, signs it, and it is ready to attach to the claim. This process does not need to add significant time to the workflow once the template is in place.

Does This Apply if We Refer Out for CBCT Interpretation?

If a dental practice takes the CBCT in-house but refers the formal interpretation to a separate radiologist or oral and maxillofacial radiologist, the billing splits between the technical component (the practice — billed with modifier TC) and the professional component (the interpreting radiologist — billed with modifier 26). In that scenario, the radiologist's separate report satisfies the UHC requirement for the professional component.

The bundling issue arises specifically when the same provider bills both the E/M and the global radiology code (or the professional component) on the same date. If your practice is doing in-house interpretation and billing globally, you need the written report.

Key Takeaways

  • Effective April 1, 2026, UHC requires a separate written radiology interpretation report when billing E/M + CBCT on the same date by the same provider
  • Without the report, the CBCT professional component is bundled into the E/M payment — no separate reimbursement
  • The report must be consistent with ACR guidelines and exist as a standalone document, not embedded in the exam note
  • The report must be attached to the UHC claim at the time of submission
  • Practices referring interpretation to a separate radiologist are less affected — the radiologist's report satisfies the requirement for the professional component
  • Build a CBCT report template into your workflow now to protect reimbursement going forward
