Unspecified anomaly of jaw size

This code signifies an abnormal jaw dimension, either excessively large (macrognathia) or small (micrognathia), where the specific nature of the anomaly is not documented. It indicates a deviation from normal jaw size without further specification of the type or etiology.

Use this code when documentation indicates an anomaly of jaw size but lacks details to specify whether it's micrognathia, macrognathia, or a specific type like prognathism or retrognathism. This is appropriate when the provider notes "jaw size anomaly" or "abnormal jaw size" without further elaboration.

• Avoid using this code if the documentation specifies the type of jaw anomaly (e.g., M26.01 for maxillary macrognathia).
• Query the provider for more specific documentation if possible to allow for a more precise code assignment.
• This code should be used as a last resort when no further information about the jaw size anomaly is available.
