Apicoectomy Additional Root - CDT Code Guide

Endodontics/Apicoectomy/Periradicular Services

Overview

CDT code D3426 pertains to the apicoectomy procedure performed on each additional root beyond the first during endodontic surgery. This code is typically used in cases involving premolars and molars, where multiple roots require surgical intervention. An apicoectomy involves the removal of the tip of a tooth's root to eliminate infection and promote healing. This procedure is often necessary when a root canal treatment has failed or when there is persistent inflammation or infection at the root tip. It's important to note that D3426 does not cover the placement of retrograde filling materials, which may be billed separately.

When to Use This Code

  • When performing an apicoectomy on a molar with multiple roots.
  • In cases where a previous root canal treatment has failed and additional roots need treatment.
  • During endodontic surgery on a premolar with more than one root requiring intervention.
  • When there is persistent infection or inflammation at the root tip of multiple roots.
  • As part of a comprehensive endodontic treatment plan involving multiple roots.

Documentation Requirements

  • Detailed clinical notes describing the need for apicoectomy on additional roots.
  • Radiographic evidence supporting the necessity of the procedure.
  • Pre- and post-operative images or radiographs.
  • Documentation of patient consent for the procedure.
  • A clear outline of the treatment plan including the number of roots treated.

Billing Considerations

When billing for D3426, ensure that it is used only for additional roots beyond the first. The primary root should be billed under a different code. Be aware of any frequency limitations imposed by insurance providers. Common modifiers may include those indicating bilateral procedures or multiple procedures. Verify with the patient's insurance for coverage specifics, as some plans may have restrictions on endodontic surgeries.
