Space Maintainer Fixed Bilateral - CDT Code Guide

Preventive/Space Maintenance (Passive Appliances)

Overview

CDT code D1517 refers to the placement of a fixed bilateral space maintainer in the mandibular arch. This preventive procedure is essential for maintaining the space left by prematurely lost primary teeth, ensuring proper alignment and spacing for the eruption of permanent teeth. Typically, this procedure is used in pediatric dentistry when a child loses multiple teeth on both sides of the lower jaw. The space maintainer is a passive appliance that helps prevent the shifting of adjacent teeth, which can lead to misalignment and bite issues. By maintaining the space, it supports the healthy development of the child's dental arch and occlusion.

When to Use This Code

When a child loses primary molars prematurely on both sides of the mandibular arch.
In cases where there is a risk of adjacent teeth shifting into the space of missing teeth.
To prevent potential crowding or misalignment of permanent teeth due to early tooth loss.
When advised by an orthodontist as part of a comprehensive treatment plan.
In situations where maintaining arch integrity is crucial for future orthodontic work.

Documentation Requirements

Detailed patient chart notes indicating the reason for space maintenance.
Radiographs showing the current dental status and missing teeth.
Documentation of the appliance type and material used.
Patient or guardian consent forms for the procedure.
Follow-up care instructions and maintenance plan for the appliance.

Billing Considerations

When billing for D1517, consider the frequency limitations as some insurance plans may only cover space maintainers once per arch. Common modifiers include those indicating bilateral procedures. It's important to verify with the patient's insurance provider regarding coverage specifics, as some plans may require preauthorization. Additionally, note that this code is typically used for pediatric patients.
