Understanding Dental Code D0370

When to Use D0370 dental code

The D0370 dental code is designated for the capture and interpretation of maxillofacial ultrasound images. This CDT code should be used when a dental provider performs an ultrasound to evaluate the soft tissues of the maxillofacial region, such as for assessing cysts, tumors, salivary gland disorders, or trauma. It is not a routine imaging code and should only be billed when the clinical situation specifically warrants ultrasound imaging as part of the diagnostic process. Proper use of D0370 ensures accurate reporting and supports the medical necessity of advanced imaging procedures in dental care.

Documentation and Clinical Scenarios

Accurate documentation is critical when billing D0370. The provider’s clinical notes should clearly state the reason for the ultrasound, the anatomical area examined, findings, and the interpretation of results. Common clinical scenarios include evaluation of suspected salivary gland stones, soft tissue masses, or facial swelling of unknown origin. For example, if a patient presents with persistent swelling in the submandibular region, and initial radiographs are inconclusive, a maxillofacial ultrasound may be indicated to further investigate soft tissue involvement. Always ensure that the documentation supports the necessity of the procedure and aligns with the narrative submitted on the claim.

Insurance Billing Tips

When submitting a claim for D0370, verify that the patient’s dental or medical insurance plan covers advanced imaging procedures. Some plans may require preauthorization or additional documentation, such as clinical notes and a copy of the ultrasound report. Attach all supporting documents to the claim, and use precise coding to avoid denials. If the claim is denied, review the Explanation of Benefits (EOB) for the reason and be prepared to submit a claim appeal with enhanced documentation. Successful dental offices maintain a checklist for imaging claims, including insurance verification, preauthorization (if needed), and thorough documentation to streamline reimbursement and minimize Accounts Receivable (AR) delays.

Example Case for D0370

Consider a patient who arrives with unexplained facial swelling and discomfort. After an initial examination and standard radiographs, the dentist suspects a soft tissue lesion not visible on X-rays. The provider performs a maxillofacial ultrasound, capturing and interpreting the images to identify a benign cyst in the parotid region. The clinical notes detail the patient’s symptoms, the rationale for ultrasound, findings, and the interpretation. The dental office submits the claim using D0370, attaches the ultrasound report, and includes a narrative explaining the necessity. The claim is processed successfully, demonstrating the importance of proper code usage, documentation, and billing workflow.
