D1520

Space Maintainer Removable - CDT Code Guide

Preventive/Space Maintenance (Passive Appliances)

Overview

CDT code D1520 refers to a removable space maintainer designed for unilateral use per quadrant. This preventive dental procedure involves the placement of a passive appliance to maintain space in the dental arch following the premature loss of a primary tooth. Space maintainers are crucial in preventing the shifting of adjacent teeth, which can lead to misalignment and occlusion issues. Typically, this procedure is recommended for pediatric patients who have lost a primary tooth prematurely due to decay or trauma. By maintaining the space, it ensures that the permanent tooth has adequate room to erupt properly, thus aiding in the maintenance of proper dental arch form and function.

When to Use This Code

Following the premature loss of a primary molar in a child
To prevent the drifting of adjacent teeth after tooth extraction
In cases where a primary tooth is lost due to decay or trauma
When there is a risk of space closure affecting the eruption of permanent teeth
To maintain arch integrity in pediatric patients

Documentation Requirements

Detailed patient dental history and reason for tooth loss
Clinical notes on the necessity of space maintenance
Description of the appliance fabricated and its fit
Patient or guardian consent for the procedure
Follow-up plan for monitoring the appliance and dental development

Billing Considerations

When billing for D1520, it's important to check the patient's insurance plan for coverage specifics, as some plans may have frequency limitations or age restrictions. Common modifiers may include those indicating the specific quadrant treated. Ensure documentation is thorough to support the necessity of the appliance.
