Other dentofacial functional abnormalities

This code represents various functional issues affecting the teeth and facial structures that are not otherwise specified. These abnormalities can impact chewing, speaking, and overall oral function due to misaligned jaws, teeth, or other structural imbalances. It encompasses a range of conditions where the dentition and facial bones do not function harmoniously.

Use this code when documentation indicates a functional dentofacial abnormality that doesn't fit more specific M26.5x categories, such as malocclusion or occlusal anomalies. This code is appropriate for conditions like atypical swallowing patterns, tongue thrust, or other oral habits causing functional impairment not classified elsewhere. Supporting documentation should clearly describe the functional impairment and rule out more specific diagnoses.

• Ensure documentation specifies the functional aspect of the abnormality, not just a structural deviation.
• Always review other M26.5x codes first to ensure a more specific diagnosis isn't available.
• Avoid using this code if a more precise malocclusion or occlusal anomaly code (e.g., M26.2- or M26.4-) can be assigned.
