Other congenital malformations of mouth

This code describes various congenital structural anomalies of the oral cavity not specified elsewhere. It encompasses a range of developmental defects affecting the mouth's formation, excluding conditions like cleft lip/palate or macrostomia/microstomia, which have more specific codes. These malformations are present at birth and can impact oral function, speech, and feeding.

Use this code for congenital malformations of the mouth that do not have a more specific ICD-10-CM code. Examples include congenital fistulas of the mouth, congenital absence of specific oral structures (other than teeth), or other rare developmental defects of the oral cavity. Documentation should clearly state a congenital anomaly of the mouth that is not classified under other specific Q codes.

• Do not use this code for cleft lip or palate (Q35-Q37) or other specifically coded congenital anomalies of the mouth (e.g., macrostomia/microstomia Q38.0, ankyloglossia Q38.1).
• Always review documentation for a more specific diagnosis before assigning this "other specified" code.
• Ensure the documentation explicitly states the malformation is congenital; acquired conditions should be coded elsewhere.
