Retreatment of Root Canal Molar - CDT Code Guide

Endodontics/Endodontic Retreatment

Overview

CDT Code D3348 pertains to the retreatment of a previous root canal therapy on a molar. This procedure is necessary when the initial root canal treatment fails or complications arise, such as persistent infection or reinfection. It involves removing the existing root canal filling material, cleaning, shaping, and disinfecting the canal system again, and then refilling it. This code is crucial for endodontists and general dentists who manage complex cases where initial treatments have not resolved the patient's issues. Retreatment is often considered when there is evidence of new or persisting symptoms, radiographic signs of infection, or when the original treatment was incomplete.

When to Use This Code

Persistent pain or infection after initial root canal treatment
Radiographic evidence of periapical pathology post-treatment
Failed initial root canal due to missed canals or inadequate cleaning
New decay compromising the existing root canal filling
Fractured tooth or restoration affecting the root canal seal

Documentation Requirements

Detailed patient history and symptoms
Radiographic evidence supporting retreatment necessity
Clinical notes on previous root canal treatment
Documentation of patient's informed consent
Description of retreatment procedure performed
Post-operative care instructions provided to the patient

Billing Considerations

When billing for D3348, ensure that the necessity for retreatment is well-documented. Most insurance plans require evidence of failure or complications from the initial treatment. Frequency limitations may apply, and it's essential to check with the patient's insurance for coverage specifics. Common modifiers include those indicating the tooth number and any special circumstances. Coordination with the insurance provider is recommended to confirm patient benefits and potential out-of-pocket costs.
