Is decoronation a common procedure?

While not as common as other endodontic procedures, it is essential in specific clinical scenarios where bone preservation is critical.

Can decoronation be performed on any tooth?

It is typically performed on non-restorable teeth where root preservation is necessary, often based on clinical judgment and treatment planning.

Does insurance usually cover decoronation?

Coverage varies by provider and plan; it is important to verify with the patient's insurance and obtain any necessary pre-authorizations.

What are the post-procedure care instructions?

Patients should follow standard post-operative care, including managing discomfort and monitoring for any signs of infection or complications.

Decoronation of Erupted Tooth - CDT Code Guide

Endodontics/Other Endodontic Procedures

Overview

CDT code D3921 refers to the decoronation or submergence of an erupted tooth, a procedure primarily aimed at preserving the root and surrounding bone structure. This involves the intentional removal of the coronal portion of a tooth, which can be crucial in cases where maintaining the root is necessary for future dental work or to prevent bone resorption. Typically, this procedure is performed when a tooth is non-restorable or when orthodontic or prosthetic plans require the preservation of the alveolar bone. By removing the crown and allowing the root to remain submerged, dentists can maintain the integrity of the bone structure, which is essential for future dental procedures.

When to Use This Code

When a tooth is non-restorable, but root preservation is necessary.
In preparation for future orthodontic treatment requiring bone preservation.
To prevent alveolar bone resorption in cases of severe decay or trauma.
When a prosthetic plan necessitates maintaining the root structure.
In pediatric cases where maintaining space for future permanent teeth is needed.

Documentation Requirements

Detailed patient history and clinical findings justifying the procedure.
Radiographic evidence supporting the need for decoronation.
Comprehensive treatment plan outlining the reasons for root preservation.
Informed consent from the patient, acknowledging understanding of the procedure.
Post-operative notes detailing the procedure and any complications.

Billing Considerations

Ensure accurate documentation of the clinical necessity for decoronation. Be aware of any frequency limitations imposed by insurance providers. Common modifiers may include those indicating a distinct procedural service. Verify with the patient's insurance for coverage specifics, as this procedure may be subject to pre-authorization requirements.
