Malocclusion, Angle's class I

This code represents a specific type of malocclusion where the mesiobuccal cusp of the maxillary first molar occludes with the buccal groove of the mandibular first molar, but other dental irregularities such as crowding, spacing, or rotations are present. Despite the correct molar relationship, there are deviations in tooth alignment that require orthodontic intervention.

Use this code when documentation clearly indicates a Class I molar relationship with coexisting dental anomalies like crowding, spacing, or crossbite. This diagnosis is typically made by an orthodontist or dentist during a comprehensive oral examination. Supporting documentation should include findings from clinical examination, dental models, and radiographic analysis.

• Ensure the documentation explicitly states "Angle's Class I" and details the associated dental irregularities.
• Do not confuse with other Angle's classes (Class II or Class III) which involve different molar relationships.
• Consider additional codes for specific dental anomalies (e.g., K07.31 for crowding, K07.32 for spacing) if further specificity is warranted and documented.
