Other congenital malformations of tongue

This code represents various congenital structural abnormalities of the tongue not classified elsewhere. These malformations can affect the tongue's size, shape, or attachment, potentially impacting speech, swallowing, and oral hygiene. Examples include bifid tongue, aglossia, or hypoglossia when not specified as macroglossia or microglossia.

Use this code when documentation specifies a congenital malformation of the tongue that is not specifically coded elsewhere, such as ankyloglossia (tongue-tie), macroglossia, or microglossia. This code is appropriate for conditions like partial or complete absence of the tongue (aglossia/hypoglossia) or a cleft tongue (bifid tongue). The physician's notes should clearly describe the specific congenital anomaly.

• Do not use this code for ankyloglossia (Q38.1), macroglossia (Q38.2), or microglossia (Q38.2).
• Ensure the documentation specifies "congenital" to differentiate from acquired tongue conditions.
• Consider additional codes for associated symptoms or functional impairments (e.g., dysphagia, speech articulation disorders).
