Tooth Fragment Reattachment - CDT Code Guide
Overview
CDT code D2921 refers to the reattachment of a tooth fragment, specifically at the incisal edge or cusp. This restorative procedure is typically employed when a portion of a tooth has fractured or broken off, and the fragment can be successfully reattached to restore the tooth's function and aesthetics. The process involves cleaning the fragment and the remaining tooth structure, applying an appropriate bonding agent, and carefully reattaching the fragment. This procedure is often used in cases of trauma or accidents where the tooth fragment is intact and viable for reattachment. Clinically, it is a conservative approach that preserves the natural tooth structure and can be a preferable alternative to more invasive restorative methods.
When to Use This Code
- A patient presents with a fractured incisal edge due to trauma, and the fragment is available for reattachment.
- A cusp has broken off during mastication, and the fragment is intact.
- A child has chipped a tooth during sports, and the fragment can be retrieved and reused.
- A patient experiences a fracture due to bruxism, and the fragment is suitable for reattachment.
- Aesthetic concerns arise from a chipped tooth, and reattachment is feasible.
Documentation Requirements
- Detailed clinical notes describing the incident leading to the fracture.
- Photographic evidence of the tooth before and after the procedure.
- Documentation of the condition of the fragment and remaining tooth structure.
- Description of the materials and bonding agents used during the procedure.
- Patient consent form acknowledging the procedure and potential outcomes.
- Post-procedure care instructions provided to the patient.
Billing Considerations
When billing for D2921, it is important to ensure that the procedure is justified by the clinical situation and documented appropriately. Frequency limitations may apply, as this procedure is typically performed on an as-needed basis following trauma. Common modifiers may include those indicating emergency treatment or trauma-related care. Insurance coverage can vary, so verifying with the patient's provider is recommended to ensure the procedure is covered under their plan.
