Horizontal displacement of fully erupted tooth or teeth

This code signifies a malposition of one or more fully erupted permanent teeth where the tooth is shifted horizontally within the dental arch, rather than being rotated, tilted, or impacted. This displacement can affect occlusion and lead to various dental issues.

Use this code when documentation indicates a fully erupted tooth or teeth are horizontally displaced, such as a tooth pushed buccally or lingually out of its normal arch alignment. Supporting documentation would include clinical notes from a dentist or orthodontist detailing the specific horizontal malposition of permanent dentition.

• Differentiate from other malocclusion codes like M26.2- for displacement due to trauma or M26.30 for unspecified tooth displacement.
• Ensure the documentation specifies "horizontal displacement" and that the tooth is "fully erupted."
• Consider additional codes for associated malocclusions (e.g., M26.4- for malocclusion, unspecified) or dental anomalies if present.
