D2989

Excavation of Non-Restorable Tooth - CDT Code Guide

Restorative

Overview

CDT code D2989 refers to the excavation of a tooth that results in the determination of non-restorability. This procedure involves the removal of decayed or damaged tooth structure to assess whether the tooth can be restored. Typically, this code is used when a dentist needs to explore the extent of decay or damage to decide if a tooth can be saved or if extraction is necessary. Clinically, this is a crucial step in treatment planning, particularly in cases where the prognosis of a tooth is uncertain due to extensive decay or structural compromise.

When to Use This Code

When a tooth exhibits extensive decay and the restorability is in question.
In cases where a tooth has suffered trauma and needs evaluation for restoration potential.
During a comprehensive dental examination where the structural integrity of a tooth is uncertain.
When previous restorations have failed, and the tooth's viability needs assessment.
Prior to planning extensive restorative procedures to determine the feasibility of saving the tooth.

Documentation Requirements

Detailed clinical notes describing the condition of the tooth before excavation.
Radiographic evidence supporting the need for excavation.
Documentation of the findings post-excavation, including the determination of non-restorability.
Patient consent forms acknowledging the procedure and potential outcomes.
Photographic evidence, if applicable, to support clinical findings.

Billing Considerations

When billing for D2989, it is important to note that this code is used when the tooth is determined to be non-restorable after excavation. It is not typically covered by insurance if the tooth is restorable. Frequency limitations may apply, and this code should not be used in conjunction with codes for restorative procedures on the same tooth. Common modifiers include those indicating the quadrant or arch. Always verify with the patient's insurance for specific coverage details.
