Retreatment of Root Canal Premolar - CDT Code Guide

Endodontics/Endodontic Retreatment

Overview

CDT Code D3347 pertains to the retreatment of a previous root canal therapy specifically for premolars. This procedure is necessary when the initial root canal treatment fails or complications arise, such as persistent infection or new decay. During the retreatment, the dentist will remove the existing filling material, clean and disinfect the canal system, and refill the canals. This code is crucial for addressing issues that compromise the success of the initial root canal, ensuring the tooth's health and functionality are restored. Dental professionals often encounter this scenario when a patient presents with symptoms like pain or swelling in a previously treated tooth.

When to Use This Code

When a patient experiences persistent pain or infection in a previously treated premolar.
If radiographic evidence shows new decay or infection in the root canal of a premolar.
When the initial root canal treatment was incomplete or inadequately sealed.
In cases where the previous root canal filling material has deteriorated.
When a new restoration is planned, and the integrity of the previous root canal is in question.

Documentation Requirements

Detailed clinical notes describing the symptoms and reason for retreatment.
Radiographic evidence supporting the need for retreatment.
Documentation of the initial root canal treatment and its outcomes.
Patient consent for retreatment procedure.
Description of the retreatment procedure performed, including materials used.
Post-operative instructions and follow-up care plan.

Billing Considerations

When billing for D3347, ensure that the need for retreatment is well-documented, as insurance may require evidence of failure of the initial treatment. Frequency limitations may apply, and it's important to check the patient's insurance policy for coverage details. Common modifiers might include those indicating the tooth number or quadrant. Coordination with insurance providers is crucial to confirm coverage for retreatment procedures.
