Understanding Dental Code D0705

When to Use D0705 dental code

The D0705 dental code is designated for an extra-oral posterior dental radiographic image, specifically for image capture only. This code is used when a dental practice needs to obtain diagnostic images of the posterior teeth (molars and premolars) using an extra-oral technique, such as a panoramic or extra-oral bitewing, but without interpretation or reporting. D0705 is most appropriate when intraoral imaging is not feasible due to patient limitations (e.g., severe gag reflex, limited mouth opening, or pediatric cooperation issues) or when extra-oral imaging provides superior diagnostic value for posterior segments.

Documentation and Clinical Scenarios

Accurate documentation is critical for correct billing and insurance reimbursement. When using D0705, ensure the clinical notes clearly state:

• The reason intraoral imaging was not possible or not optimal
• The clinical indication for the extra-oral image (e.g., caries detection, evaluation of restorations, or assessment of periodontal status in posterior teeth)
• The specific area imaged (e.g., upper right molars)
• Confirmation that only image capture was performed (no interpretation or report included)

Common scenarios include patients with special needs, young children who cannot tolerate intraoral sensors, or cases where anatomical limitations make intraoral imaging ineffective. Always align documentation with the medical necessity to support claim approval.

Insurance Billing Tips

When submitting claims for D0705, follow these best practices to maximize reimbursement and reduce denials:

• Verify benefits: Check with the patient’s dental insurance to confirm coverage for extra-oral radiographs and any frequency limitations.
• Attach supporting documentation: Include clinical notes and, if possible, a narrative explaining why extra-oral imaging was necessary.
• Use accurate CDT codes: Ensure D0705 is not billed alongside other radiographic codes for the same area on the same date of service unless medically justified. If a different type of radiograph is performed, use the appropriate code (e.g., D0330 panoramic radiograph).
• Review EOBs (Explanation of Benefits): If a claim is denied, review the EOB for the denial reason and prepare a claim appeal with additional documentation if needed.

Consistent use of these steps helps maintain clean claims and minimizes accounts receivable (AR) delays.

Example Case for D0705

Case: A 7-year-old patient presents for a routine exam, but is unable to tolerate intraoral bitewing radiographs due to a strong gag reflex. The dentist determines that an extra-oral posterior image is necessary to evaluate the child’s molars for interproximal caries. The clinical note documents the failed intraoral attempt, the reason for extra-oral imaging, and the area captured. The office bills D0705 for image capture only, attaches a brief narrative, and receives insurance reimbursement after claim review.

This example highlights the importance of matching the code to the clinical scenario and providing thorough documentation to support billing.
