Supernumerary teeth

This code represents the presence of extra teeth beyond the normal complement in the dental arch. These supernumerary teeth, also known as hyperdontia, can occur in any region of the mouth and may be impacted, erupted, or unerupted. They can lead to various dental complications, including malocclusion, impaction of permanent teeth, and cyst formation.

Use this code when documentation clearly indicates the presence of one or more teeth in excess of the typical number. This includes conditions like mesiodens (supernumerary tooth between the central incisors), paramolars, or distomolars. Supporting documentation would include dental radiographs, clinical examination findings, and dentist's notes confirming hyperdontia.

• Differentiate from retained deciduous teeth, which are primary teeth that have not exfoliated.
• Specify the location and type of supernumerary tooth if further detail is available in the documentation.
• Consider sequencing this code with other dental conditions, such as malocclusion (524.x) or impacted teeth (520.6), if they are also present and documented.
