Understanding Dental Code D0385

When to Use D0385 dental code

The D0385 dental code is designated for the "maxillofacial MRI image capture" procedure. This CDT code is specifically used when a dental provider captures magnetic resonance imaging (MRI) of the maxillofacial region, which includes the jaw, facial bones, and surrounding soft tissues. Dental practices should use D0385 when advanced imaging is necessary to diagnose complex conditions such as temporomandibular joint (TMJ) disorders, cysts, tumors, or other abnormalities that cannot be fully evaluated with standard dental radiographs or cone beam CT scans. Always confirm that the imaging is medically necessary and supported by clinical findings before using this code.

Documentation and Clinical Scenarios

Accurate documentation is critical when billing for D0385. The clinical record should clearly state:

• The specific reason for ordering the MRI (e.g., persistent TMJ pain, suspected neoplasm, or unexplained facial swelling).
• Previous diagnostic steps taken, such as panoramic or intraoral radiographs, and why further imaging is required.
• Detailed clinical notes, including the patient’s symptoms, exam findings, and any relevant medical or dental history.
• The provider’s interpretation of the MRI images, if available.

Common clinical scenarios for D0385 include evaluating TMJ dysfunction when conservative treatments have failed, assessing the extent of facial trauma, or investigating lesions that require high-resolution soft tissue imaging. Proper documentation not only supports claim approval but also ensures compliance in the event of an audit.

Insurance Billing Tips

Billing for D0385 can be challenging, as many dental insurance plans have limited coverage for advanced imaging like MRIs. Here are best practices to maximize reimbursement and minimize denials:

• Verify coverage: Before scheduling the MRI, contact the patient’s dental and medical insurers to determine if D0385 is a covered benefit. Some plans may require pre-authorization or may only cover the procedure under specific conditions.
• Submit supporting documentation: Include clinical notes, prior imaging results, and a clear narrative explaining the medical necessity of the MRI with your claim.
• Use correct coding: Ensure D0385 is listed as the primary procedure code. If additional procedures are performed, code them separately and provide cross-references as needed.
• Appeal denials: If a claim is denied, review the Explanation of Benefits (EOB) for the reason. Submit a detailed appeal letter with additional documentation, emphasizing the necessity and relevance of the MRI to the patient’s diagnosis and treatment plan.

Staying proactive with insurance verification and thorough documentation can significantly improve claim outcomes for D0385.

Example Case for D0385

Case: A 45-year-old patient presents with chronic jaw pain and limited mouth opening. Initial panoramic radiographs and clinical exams are inconclusive. Conservative TMJ therapy has not resolved symptoms. The dentist determines that a maxillofacial MRI is necessary to evaluate soft tissue structures and rule out internal derangement or pathology.

Workflow:

1. The dental team verifies insurance coverage for D0385 and obtains pre-authorization.
2. Detailed clinical notes are entered, documenting the patient’s symptoms, failed treatments, and rationale for MRI.
3. The MRI is performed, and the provider documents findings and next steps in the patient’s chart.
4. A claim is submitted with D0385 as the primary code, along with supporting documentation.
5. If the claim is denied, the office submits an appeal with a comprehensive narrative and any additional requested records.

This approach ensures compliance, supports medical necessity, and increases the likelihood of successful reimbursement for advanced imaging procedures like D0385.
