Tongue tie

This code describes ankyloglossia, a congenital anomaly characterized by an abnormally short or thick lingual frenulum that restricts the tongue's range of motion. This restriction can interfere with breastfeeding, speech development, and oral hygiene.

Use this code when documentation clearly indicates a diagnosis of ankyloglossia, often referred to as "tongue tie." This diagnosis is typically made during a physical examination, observing the limited movement of the tongue.

• Ensure documentation specifies "ankyloglossia" or "tongue tie" and not just "frenulum abnormality" without functional impairment.
• Do not confuse with other congenital anomalies of the tongue (e.g., macroglossia, microglossia) unless ankyloglossia is also present.
• If a frenotomy or frenuloplasty is performed, this diagnosis code would support the medical necessity of the procedure.
