How often should a maxillary partial denture be rebased?

The need for rebasing depends on individual patient factors, but it is generally considered when the denture becomes loose or uncomfortable.

Is rebasing covered by dental insurance?

Coverage varies by insurance plan, so it's important to verify benefits and any frequency limitations before proceeding.

Can rebasing improve the appearance of my denture?

Rebase Maxillary Partial Denture - CDT Code Guide

Prosthodontics, removable/Denture Rebase Procedures

Overview

CDT code D5720 refers to the procedure of rebasing a maxillary partial denture. This involves replacing the base material of an existing denture without changing the occlusal relations. The procedure is typically necessary when the denture base has deteriorated or no longer fits properly due to changes in the oral cavity, such as bone resorption or tissue shrinkage. Rebasing helps improve the fit and comfort of the denture, ensuring better functionality and patient satisfaction. Dental professionals may recommend this procedure to extend the life of a denture and maintain oral health.

When to Use This Code

When the base of a maxillary partial denture has worn out or deteriorated.
If the patient experiences discomfort due to a loose-fitting denture.
When there are changes in the oral cavity, such as bone resorption, affecting denture fit.
To improve the stability and retention of an existing maxillary partial denture.
When the patient reports difficulty in chewing or speaking due to denture instability.

Documentation Requirements

Detailed patient history and examination notes indicating the need for rebasing.
Clinical notes describing the condition of the existing denture base.
Documentation of oral changes such as bone resorption or tissue shrinkage.
Patient consent form acknowledging understanding of the rebasing procedure.
Laboratory prescription and communication records for the rebase process.
Post-procedure evaluation notes to confirm improved fit and function.

Billing Considerations

When billing for D5720, it is important to verify the patient's insurance coverage for prosthodontic procedures, as policies may vary. Rebasing is typically covered less frequently than new dentures, so check for any frequency limitations. Common modifiers may include those indicating the arch (upper or lower) or adjustments. Ensure documentation is thorough to support the necessity of the procedure.
