Hydroxyapatite Regeneration - CDT Code Guide

Restorative

Overview

CDT code D2991 refers to the application of hydroxyapatite regeneration medicament per tooth. This procedure is part of restorative dentistry and involves the application of a medicament designed to promote the regeneration of hydroxyapatite, a naturally occurring mineral form of calcium apatite. Hydroxyapatite is a critical component of tooth enamel and bone, and its regeneration can help in strengthening teeth and repairing early stages of tooth decay. Typically, this procedure is used in cases where there is a need to enhance the mineral content of the tooth structure, potentially reversing early decay or strengthening weakened enamel. Dental professionals may apply this treatment in conjunction with other restorative procedures to ensure comprehensive care.

When to Use This Code

When a patient presents with early signs of enamel demineralization.
As part of a treatment plan for patients with high caries risk.
To strengthen enamel in patients with erosion due to dietary acids.
In conjunction with other restorative procedures to enhance outcomes.
For patients with sensitivity due to enamel thinning.

Documentation Requirements

Detailed patient history and examination notes.
Clinical justification for the use of hydroxyapatite regeneration.
Documentation of the tooth/teeth treated with the medicament.
Description of the procedure performed, including materials used.
Patient consent forms acknowledging understanding of the procedure.
Post-procedure care instructions provided to the patient.

Billing Considerations

When billing for D2991, ensure that the procedure is documented thoroughly to justify its necessity. Check with the patient's insurance for coverage details, as some plans may consider this a preventive or restorative procedure. Be aware of any frequency limitations that might apply to similar treatments. Common modifiers might include those indicating the specific tooth treated. Coordination with other restorative codes may be necessary if performed as part of a larger treatment plan.
