Abnormalities of size and form of teeth

This code signifies developmental anomalies affecting the physical dimensions or morphology of teeth, such as abnormally large (macrodontia) or small (microdontia) teeth, or teeth with unusual shapes (e.g., peg laterals, gemination, fusion). It represents congenital or acquired deviations from normal tooth size and form, excluding issues related to eruption or number.

Use this code when documentation specifies a patient presents with teeth that are unusually large, small, or malformed. This includes conditions like macrodontia, microdontia, dens invaginatus, taurodontism, or supernumerary roots. Supporting documentation should clearly describe the specific size or form abnormality observed during clinical examination or radiographic imaging.

• Do not use for abnormalities in the number of teeth (e.g., anodontia, supernumerary teeth) or eruption disturbances.
• Specify the exact type of abnormality (e.g., macrodontia, peg lateral) in the documentation for optimal specificity.
• Consider sequencing this code as a primary diagnosis when the abnormality is the main reason for the encounter, or as a secondary diagnosis when it's an associated finding.
