Understanding Dental Code D3502

When to Use D3502 dental code

The D3502 dental code is designated for the surgical exposure of a root surface without apicoectomy or repair of root resorption specifically for premolars. This code is most commonly used when a dentist or oral surgeon needs to access the root surface of a premolar for reasons such as facilitating orthodontic movement, removing obstacles to eruption, or addressing localized pathology—without performing an apicoectomy or repairing root resorption. Proper use of D3502 ensures accurate reporting and reimbursement for the surgical procedure performed.

Documentation and Clinical Scenarios

Accurate documentation is critical for successful claims involving D3502. The clinical notes should clearly state:

• The specific premolar involved
• The reason for surgical exposure (e.g., to aid orthodontic eruption, remove a physical barrier, or manage localized pathology)
• Details of the procedure, including anesthesia, incision, and flap elevation
• Confirmation that neither an apicoectomy nor root resorption repair was performed

Common scenarios include exposing an unerupted premolar for orthodontic bracket placement or to remove a cystic lesion impeding eruption. Always include pre- and post-operative radiographs and intraoral photos in the patient record to support the necessity and extent of the procedure.

Insurance Billing Tips

To maximize reimbursement and reduce denials for D3502, follow these best practices:

• Verify coverage: Before treatment, check with the patient’s dental plan to confirm benefits for surgical exposure procedures. Not all plans cover D3502, especially if performed for orthodontic reasons.
• Submit comprehensive documentation: Attach clinical notes, radiographs, and intraoral images to your claim. Clearly indicate that no apicoectomy or root resorption repair was performed.
• Use correct CDT codes: If additional procedures are performed (e.g., bone grafting), use the appropriate codes and document separately. For apicoectomy, see apicoectomy code guidance.
• Monitor EOBs and AR: Review Explanation of Benefits (EOBs) promptly. If D3502 is denied, check the denial reason and prepare a claim appeal with supplemental documentation if medically necessary.

Clear, detailed documentation and proactive communication with insurance carriers are key to successful billing for D3502.

Example Case for D3502

Case: A 14-year-old patient requires exposure of an unerupted lower right second premolar to enable orthodontic bracket placement. The oral surgeon elevates a flap to expose the crown and root surface, but no apicoectomy or resorption repair is performed. The procedure is documented with pre- and post-op radiographs and detailed clinical notes. The claim is submitted with D3502, supporting images, and a narrative explaining the orthodontic necessity. The insurance carrier processes the claim and reimburses according to plan benefits.

This example highlights the importance of precise coding, thorough documentation, and clear communication between clinical and billing teams.
