Endodontic Therapy, Premolar - CDT Code Guide
Overview
CDT code D3320 refers to endodontic therapy specifically for premolar teeth, excluding the final restoration. This procedure involves complete root canal therapy, which includes the removal of infected or damaged pulp tissue and the sealing of the tooth to prevent further infection. It is applicable to both primary teeth without succedaneous teeth and permanent teeth. The process encompasses all necessary appointments to complete the treatment, including intra-operative radiographs, but does not cover the initial diagnostic evaluation or necessary radiographs. This code is crucial for treating teeth that have experienced decay or trauma, leading to pulp exposure or infection.
When to Use This Code
- When a premolar tooth has deep decay reaching the pulp
- In cases of trauma to a premolar resulting in pulp exposure
- When a premolar shows signs of pulp necrosis or irreversible pulpitis
- For a primary premolar without a succedaneous tooth requiring root canal therapy
- When a premolar requires complete root canal therapy excluding the final restoration
Documentation Requirements
- Detailed clinical notes of the diagnosis and treatment plan
- Intra-operative radiographs showing the procedure
- Records of all appointments related to the treatment
- Patient consent forms for endodontic therapy
- Documentation of any complications or additional procedures performed
- Exclusion of diagnostic evaluations and initial radiographs from this code
Billing Considerations
D3320 should be billed when complete root canal therapy is performed on a premolar. It does not include the final restoration, which should be billed separately. Be aware of insurance policies regarding frequency limitations and ensure that all intra-operative radiographs are documented. Common modifiers may include those indicating the tooth number or quadrant.
