D1558Removal of Fixed Bilateral Space Maintainer - Mandibular

What This Code Covers

D1558 covers removal of fixed bilateral space maintainer - mandibular. The appliance is removed when the permanent teeth have erupted or when continued space maintenance is no longer indicated. This code covers only the removal procedure and not any replacement appliance.

Billing Guide

Bill this code when:

• The specific space maintainer procedure described by D1558 is performed
• The arch (maxillary or mandibular) matches the code description
• Documentation confirms the clinical indication for the procedure

Do not bill this code when:

• The arch does not match. Verify maxillary vs. mandibular coding
• The appliance type (fixed vs. removable, unilateral vs. bilateral) does not match
• A new appliance is being fabricated when a re-cementation code should be used, or vice versa
• The procedure is better described by D1551 (Re-cement or re-bond bilateral space maintainer - ...)
